How to use bright light therapy for increased anxiety, increased panic and SAD during the cold dark winter months

January 19, 2024 By Trudy Scott 2 Comments

There is a seasonality to anxiety and panic disorder just as there are seasonal variations in mood for certain susceptible individuals:

Following a clinical observation of increased anxiety symptoms and mood changes during winter in panic disorder patients, the Seasonal Pattern Assessment Questionnaire (SPAQ) was completed by 133 patients. Global Seasonality Scores (GSS), and the prevalence of Seasonal Affective Disorder (SAD), were significantly higher than reported in general population studies.

Seasonal changes were also found in anxiety and panic attacks.

These findings suggest the possibility of a common aetiology [etiology or cause] for panic disorder and SAD, that seasonality may be a far more general phenomenon in psychopathology, and that light therapy may be a useful treatment for some panic disorder patients.

The above abstract is from this paper: Seasonality in panic disorder

If you’re new to bright light therapy or are currently using it with success and would like to learn more, I’d like to point you to this excellent review paper, Bright Light as a Personalized Precision Treatment of Mood Disorders. The authors of the above paper cover some of the basics like how to use bright light for SAD (seasonal affective disorder) or the winter blues, and for how long, possible adverse effects and who should not use bright light therapy (this last aspect is theoretical).

This information about bright light and mood disorders can be applied to anxiety and panic attacks, in addition to SAD.

As you’ll read below there are also often benefits for non seasonal depression, bipolar disorder, fatigue, sleep issues, emotional eating and other conditions too. And bright light therapy can be used in conjunction with the amino acids tryptophan or 5-HTP, and is often used with psychiatric medications too.

How to use bright light for SAD and winter anxiety/panic and for how long?

You sit in front of the light box or full spectrum lamp – on a table or your desk – with open eyes. Using a standing lamp as a source of light is another option.

The authors of the Bright Light paper share the following approach for SAD (seasonal affective disorder or the winter blues), all of which is applicable for increased anxiety and panic attacks in winter too):

Start with a “duration of 30 minutes, using a light intensity of 10,000 lux.” (more on lux comparisons below)
“Early morning administration offers greater chances for remission” (although there is documented research and clinical results that for some folks later in the day works well too).
“Measured at eye level, a therapeutic distance of 60–80 cm from the light box can be seen as standard requirements (some other devices recommend a distance of 30 cm, so we advise to follow the device recommendations that take into account light parameters and distance).” Most of the lights/devices I recommend state a distance of 30 cm so it’s best to follow the manufacturer’s guidelines.
“Lower intensities also appear to be effective, but need longer exposure durations: 2,500 Lux for 2 hours per day or 5,000 Lux for 1 hour a day.” This means sitting further away may allow you to sit in front of the lamp/device for longer duration and get the same benefits.
“Significant effects appear only at 2–3 weeks of treatment.” Based on my clinical results, I have clients start to feel some improvements right away with the correct distance and a good lamp.
“Treatment is usually continued until the time of usual spontaneous remission in the spring or summer” (and is ideally started as fall/autumn starts to approach rather than in the middle of winter).

I’m also adding this missing and yet important fact from another paper: “The light box is angled ~30° from the line of gaze. The user does not stare directly into the light.”

They also discuss guidelines for year round use of bright light therapy for non-seasonal unipolar depression, another term for major depressive disorder. And midday or morning use for bipolar depression (when on mood stabilizers). I share more about this in my blog: Midday bright light therapy for bipolar depression. I refer you to the study for this information so it can be discussed with your doctor.

Bright light therapy for insomnia and decreased alertness/fatigue

The Bright Light paper also mentions how light therapy “may also be useful to improve sleep quality” … and … “abnormalities in circadian rhythms such as sleep phase delay syndrome, that are frequently associated in mood disorders.”

The authors also mention how light therapy can also help “decreased alertness”, presumably as a result of poor sleep.

Clinically, I see these benefits for clients in similar ways that tryptophan or 5-HTP help with sleep issues. This is related to the serotonin boosting mechanism of bright light therapy. Keep in mind anxiety and panic are symptoms of low serotonin.

What are some possible adverse effects of bright light therapy?

The authors state that bright light therapy “is well-tolerated by patients; adverse effects such as headache, eyestrain, nausea and agitation, are usually transient and mild.” Clinically, I have seldom seen clients experience headache, eyestrain and nausea.

However, I have seen agitation and other low serotonin symptoms get worse – like feeling more sad or more worried or more angry or more irritated or more sleep issues (or all of the above). Too much bright light therapy can ramp up low serotonin symptoms in a similar way that too much tryptophan or 5-HTP can. In other words, it can be overdone and more is not necessarily better. You have to find a balance and figure out what works best for your needs.

I also have clients who are prescribed antidepressants discuss light therapy with their prescribing doctor as I suspect there is the possibility of serotonin syndrome. I don’t see any reports of this in the research and a number of reports of bright light therapy being used successfully in conjunction with antidepressants.

Who should not use bright light therapy?

The authors share these contraindications: “ophthalmic disorders (cataract, macular degeneration, glaucoma, retinitis pigmentosa) and disorders affecting the retina (retinopathy, diabetes, herpes, etc.).” They recommend getting an eye examination if you are in doubt.

Other papers state that the above is theoretical and there are no documented cases of eye damage from bright light therapy. But if you suspect you may be at high risk, get the approval from your ophthalmologist and ongoing monitoring too.

Recommended lights, lamps and panels: always 10,000 lux

This blog post, Winter blues or SAD: light therapy has been updated (as of Jan 2024) with new links for recommended lights/lamps/panels, all 10,000 lux. You can also read feedback from folks who use and find the benefits of full spectrum light or bright light therapy. For example, Chrstine shared this:

My office is the darkest room in the house and I have one sitting on my desk, especially helpful in the winter. This is the second Verilux Happy Light I have used and I really like it. Living in Nevada where there is sunshine over 330 days of the year I am so accustomed to light and brightness that if I am in a dark room or space for too long it really affects me. This has been a great product for me and I can recommend it.

If you’re curious about lux, it is a unit of illumination and this paper, Light Therapy in Mood Disorders: A Brief History with Physiological Insights, includes this very useful lux comparison image:

The combination of using bright light therapy with amino acids such as tryptophan and 5-HTP

I often recommend the use of light therapy in conjunction with amino acids such as tryptophan and 5-HTP. This offers additional serotonin support and helps ease worry-type anxiety, panic attacks, low mood, insomnia, cravings and more. I discuss this combination approach in the winter blues blog.

When someone is already using amino acids with some success, we may just add light therapy and keep amino acid dosing the same or we may use higher doses of amino acids like tryptophan, 5-HTP and GABA during the winter months. We may also use both depending on the person’s unique needs.

I had one client who did really well with tryptophan: his anxiety decreased dramatically but then ramped up before winter. Increasing tryptophan was too much for him so we kept the original tryptophan dose and he started bright light therapy. This worked very well for him until the end of spring when he was able to stop the light therapy.

I also share links to increased OCD (obsessive compulsive disorder), intrusive thoughts, PMDD (premenstrual dysphoric disorder), PMS (premenstrual syndrome), binge eating/emotional eating and drinking/alcoholism in the winter months – and the role of light therapy and amino acids.

Additional resources when you are new to using tryptophan or other amino acids as supplements

We use the symptoms questionnaire to figure out if low serotonin or other neurotransmitter imbalances may be an issue for you.

If you suspect low levels of any of the neurotransmitters and do not yet have my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, I highly recommend getting it and reading it before jumping in and using amino acids on your own so you are knowledgeable. And be sure to share it with the practitioner/health team you or your loved one is working with.

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control, sugar cravings, anxiety and mood issues. The importance of quality animal protein is also covered.

If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms too). This is a paid online/virtual group program where you get my guidance and community support.

If you are a practitioner, join us in The Balancing Neurotransmitters: the Fundamentals program. This is also a paid online/virtual program with an opportunity to interact with me and other practitioners who are also using the amino acids.

Do you experience increased anxiety, panic attacks and/or the winter blues in the winter months? Have you had success with bright light therapy?

If yes, which full spectrum lamp have you found to be the most useful? What time of the day do you use it, how often do you use it and for what duration?

Have you used a combination of amino acids and light therapy, and adjusted up your amino acids during the colder and darker winter months?

If you’re a practitioner do you recommend light therapy to your clients/patients?

Her mum just passed away and although she is sad, GABA allows her to sit with a feeling of peace and calm most of the time

April 7, 2023 By Trudy Scott 33 Comments

Sandra shared this heartening feedback on how GABA helped right after the passing of her mum. She also voiced her surprise that it could have such a profound effect at a sad time like this, asking me if this was possible:

I recently started taking GABA Calm lozenges. I settled on a small dose of one lozenge at bedtime. Initially I took this for tense neck and shoulder muscles due to years of anxiety.

What I have noticed in the past month is that I seem quite calm although I do still have tense neck muscles.

Last week I experienced a profound bereavement with the passing of my mum who I have been caring for. I am genuinely surprised at how I have handled this stressful situation including the funeral. I have always been quite emotional and I have found myself, although sad, sitting in a feeling of peace and calm most of the time.

Is it possible that the GABA Calm is contributing to this? It was my understanding this product would assist with my tense muscles but I feel like it has helped me tremendously with my mindset, emotions and mood.

I look forward to your reply.

I offered my condolences for the loss of her mum and said how heartened I felt, hearing that she had a feeling of peace and calm most of the time. And the fact that GABA had helped with the stressful events of the funeral and her mindset, emotions and mood. I would expect the feeling of peace and calm, and helping reduce overall stress. The calming amino acid supplement, GABA, has long been recognized to help ease the more physical type of anxiety.

But because the amount of GABA she was taking didn’t help with her tense muscles, some of the benefits may have been as a result of GABA reducing the distressing unwanted thoughts. The emotions and mood are added benefits that we don’t always hear about with GABA but are not unheard of (more on this below).

I thanked Sandra for sharing this wonderful feedback, letting her know I’d share it as a separate blog, so we can offer support to others in similar situations. I’ll also be sharing this blog with her so she understands some of the mechanisms better too. In fact, I only made the unwanted thoughts connection after having responded to her.

GABA helps with inhibition of unwanted thoughts

In the past I’ve blogged about how Scientists identified a mechanism that helps us inhibit unwanted thoughts:

We are sometimes confronted with reminders of unwanted thoughts – thoughts about unpleasant memories, images or worries. When this happens, the thought may be retrieved, making us think about it again even though we prefer not to. While being reminded in this way may not be a problem when our thoughts are positive, if the topic was unpleasant or traumatic, our thoughts may be very negative, worrying or ruminating about what happened, taking us back to the event.

Scientists have identified a key chemical within the ‘memory’ region of the brain that allows us to suppress unwanted thoughts, helping explain why people who suffer from disorders such as anxiety, post-traumatic stress disorder (PTSD), depression, and schizophrenia often experience persistent intrusive thoughts when these circuits go awry.

Professor Anderson, Dr. Schmitz and colleagues showed that the ability to inhibit unwanted thoughts relies on a neurotransmitter – a chemical within the brain that allows messages to pass between nerve cells – known as GABA.

GABA is the main ‘inhibitory’ neurotransmitter in the brain, and its release by one nerve cell can suppress activity in other cells to which it is connected.

Anderson and colleagues discovered that GABA concentrations within the hippocampus – a key area of the brain involved in memory – predict people’s ability to block the retrieval process and prevent thoughts and memories from returning.

You can read more on the blog post here: GABA helps with inhibition of unwanted thoughts

If you are using the GABA with success already and experience the loss of a loved one, you may find you need to increase your dose for a period of time.

There is individual variability in the capacity to cope with stress during bereavement

Research supports that there is “individual variability in the capacity to cope with stress” during bereavement and there are differences in symptoms and physiological changes. This paper, Long-term immune-endocrine effects of bereavement: relationships with anxiety levels and mood, identified changes in depression, anxiety, adrenocorticotropin and cortisol plasma concentrations, beta-endorphins, and reduced “functional activity of natural killer cells.” And the two different groups of people in the study had different symptoms and physiological changes.

GABA and glutamate, and the HPA axis in depression/bereavement

The above paper doesn’t mention GABA but growing evidence indicates that glutamate and GABA, and the HPA axis/corticotropin-releasing hormone, plays a role in depression and presumably bereavement too. This may be another mechanism that led to the feelings of calm that Sandra experienced.

You’ll need to figure out your unique biochemical needs

When you experience the loss of a loved one, you’ll need to figure out your unique biochemical needs and address them one by one. You may need GABA support like Sandra and/or may find you need serotonin support (with tryptophan or 5-HTP) and/or may need endorphin support (with the amino acid DPA/d-phenylalanine).

Both GABA and serotonin support also helps to address sleep problems. DPA helps especially with the emotional pain and weepiness, and if you’re self-medicating with comfort foods while grieving.

If you have high cortisol you may benefit from Seriphos or Lactium.

Keep in mind that nutritional support is immensely helpful during caregiving too. Here is just one example: When using the amino acid DPA (d-phenylalanine) I have more resilience and more buffer in the caregiving work I do, and just the oops’s of life

Helping Sandra ease her still tense neck muscles

For her ongoing tense neck and shoulder muscles I suggested a higher amount of GABA may be needed. She reported back that taking it in the morning made her sleepy and a couple of times she noticed a headache.

When GABA in the day causes sleepiness I have clients use less GABA more frequently or to take more at night to carry over the next day. In this case probably a GABA-only product because of her headaches.

She did share that GABA was her starting point with the intention of including tryptophan for ruminating and fearful thoughts which do stop her from participating in various activities. Low serotonin does cause TMJ (temporomandibular joint) pain and it’s possible this is contributing to her ongoing tense neck and shoulder muscles, and tryptophan may be the solution.

We also address low magnesium if applicable. I’d also suggest looking into dietary oxalates too and getting checked for physical issues by a chiropractor and/or osteopath and/or physical therapist.

You can read our discussion on this blog.

Resources if you are new to using GABA or tryptophan or DPA as supplements

If you are new to using GABA or tryptophan or DPA as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see all the symptoms of neurotransmitter imbalances, including low GABA, low serotonin and low endorphins).

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control, sugar cravings, anxiety and mood issues (which include rage/anger/irritability/self-harm).

The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs. You can find them all in my online store. The above oral lavender products are available in my online store too.

If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms). This is a paid online/virtual group program where you get my guidance and community support.

Has GABA or tryptophan or DPA helped you after the loss of a loved one? How did each one help?

Were you surprised that they would help so much?

If you were using the aminos with success already did you find you needed to increase your dose for a period of time?

What else has helped you at a time of loss?

Night eating syndrome: is low serotonin a root cause and is tryptophan a solution?

April 9, 2021 By Trudy Scott 28 Comments

According to this paper, Circadian Rhythm Profiles in Women with Night Eating Syndrome, “Patients with night eating syndrome (NES) – first described in 1955 – demonstrate a phase delay in the circadian pattern of food intake, manifested by evening hyperphagia, nocturnal awakenings with food intake, and morning anorexia.”

I would start by asking this question: is low serotonin a root cause and is tryptophan a possible solution? I’ll share why below and where to start in order to find a solution.

Before I do that let me explain the terminology used in the above quote: Circadian means it happens every 24 hours, hyperphagia is obsessive food-seeking behavior, nocturnal awakenings are waking in the night and anorexia refers to restricted eating in the morning.

There is no research supporting the use of serotonin support with either tryptophan or 5-HTP for night eating syndrome but I would still start here for the following reasons:

this behavior happens in the evening and at night and it’s well recognized that serotonin levels are lower later in the day and at night
carbohydrate cravings and addictions occur with low serotonin and cravings are most intense later in the day (typically afternoon and evening)
obsessive behaviors are common with low serotonin
insomnia or night-time waking is a common symptom with low serotonin
doing a trial with either of these amino acids will very quickly confirm if low serotonin is a contributing factor or will rule it out

I would also have my client look at other low serotonin symptoms which would help confirm that low serotonin may be a factor for them: worry-type of anxiety, ruminations, PMS, irritability, rage or anger, TMJ, panic attacks, perfectionism, depression, low self-esteem and so on. You can see all the low serotonin symptoms here.

We typically start with a trial of tryptophan simply because so many of my clients do so well with it. The other reason is that 5-HTP can raise cortisol and cause a wired-tired feeling. That being said, some folks do better on one vs the other so if tryptophan doesn’t help then we trial 5-HTP. You can see the products I use with my clients here on the supplements blog.

I would love to see tryptophan or 5-HTP being more extensively – because it works so effectively and quickly, and is addressing the root cause – but also because there is research that does support the serotonin connection to night eating syndrome:

Night eating syndome has been associated with “depression, emotional eating, sleep problems, and food addiction as well as with being overweight or with having obesity (especially as people age)” – all low serotonin symptoms.
Night eating patients are “responsive to selective serotonin reuptake inhibitor treatment” (antidepressant/SSRI treatment)
Bright light therapy may help with night eating because of it’s “serotonergic antidepressant mechanisms of action.” Night eating syndrome also shares features with seasonal affective disorder (SAD) and it’s not uncommon to experience both. The winter blues or SAD is common with low serotonin. I write more about SAD and bright light here.

I’d also consider low blood sugar as a contributing factor. We would need to rule out the use of the sleep medication Ambien/Zolpidem which has been shown to cause amnesia and sleep related eating disorders which resolves when the medication is stopped.

As always, it’s not only the low serotonin we need to address. Tryptophan or 5-HTP offer quick relief but we must always do a full functional workup looking at diet, nutritional deficiencies, digestion, all hormones, toxins and infections (and so on) so we can address all possible root causes – and why serotonin is low in the first place.

I share some possible reasons for low serotonin on this blog on imposter syndrome. Imposter syndrome is another common sign of low serotonin.

Have you been diagnosed with night eating syndrome or do you feel you possibly fit the profile? Does it happen every night and what foods are you drawn to? Which low serotonin symptoms can you relate to and has tryptophan or 5-HTP helped? What about light therapy? And was an antidepressant prescribed?

Feel free to post your questions and feedback in the comments below.

Winter blues or SAD: light therapy

February 27, 2015 By Trudy Scott 44 Comments

Seasonal affective disorder (SAD) or “winter blues” is a form of depression most often associated with the lack of light during the fall and winter months. It is very common and may be associated with low serotonin levels. We often associate low serotonin with depression, however low serotonin can also be associated with: anxiety, excessive worry and feeling overly stressed. There’s evidence of seasonality in anxiety and panic attacks, just as there is with seasonal affective disorder (SAD). Another common sign of low serotonin is increased carbohydrate cravings, especially during the afternoon or evening.

One very effective approach for SAD is light therapy. I also find the use of targeted individual amino acids and a dietary approach to be very useful and share more about that below.

Winter Blues by Dr. Norman Rosenthal MD

I’ve just finished reading a really great book called Winter Blues: Everything You Need to Know to Beat Seasonal Affective Disorder by Dr. Norman Rosenthal MD, and the research is fascinating. He is a fellow South African who moved to the USA and found he was depressed each winter. After 3 seasons of this, he started doing research on light therapy and was one of the original SAD researchers. He is internationally recognized for his pioneering contributions to understanding SAD and using light therapy to treat it.

Feedback from colleagues: desk lamp, desk panels, floor lamps and light boxes

I asked some colleagues what they have used and/or liked, and recommend and share some of these below (providing my Amazon links in most cases so you can find them easily). Due to models being discontinued/revamped, I’ve made some updates as of Jan 2024.

Donna Kelley, Certified Holistic Nutritionist

I have a Blue Max, full spectrum, 70 watt dimmable desk lamp. I have had it for 3 years and actually use it to work by. It was recommended by Julia Ross in her certification program. (The company that makes this one is Full Spectrum Solutions)

UPDATE: Jan 2024 – the above model is no longer available but a very comparable one is the Verilux HappyLight Duo – 2-in-1 Light Therapy & Task Desk Lamp. Be sure to read some of the reviews. This is a really good one: “providing me with light therapy to lift my mood some during these dark times (literally since it’s winter…and figuratively…). I genuinely think I feel better/lighter/cheerier after I’ve been working by my HappyLight Duo for several hours.”

Christine Wokowsky, Board Certified in Holistic Nutrition

My office is the darkest room in the house and I have one sitting on my desk, especially helpful in the winter. This is the second Verilux Happy Light I have used and I really like it. Living in Nevada where there is sunshine over 330 days of the year I am so accustomed to light and brightness if I am in a dark room or space for too long it really affects me. This has been a great product for me and I can recommend it.

Tracey Schuyler, Owner, Nutrition Counselor at Redefining Food 4 Health, LLC, also likes the Verilux

Like Christine, I personally use the Verilux Happy Light, which I purchased recently. It made a difference right away. I live in Boise, Idaho, and we are accustomed to winter inversions … sometimes days / weeks on end without any sunlight! I place it on my bathroom counter, turn it on in the morning before I shower, and turn it off as I’m leaving the bathroom, after drying my hair, etc. (about 25 minutes).

UPDATE: Jan 2024 – the above model, Verilux Happy Light, is no longer available but a very comparable one by the same company is the Verilux® HappyLight® Alba – New Round UV-Free LED Therapy Lamp. This one has a count-down timer and is portable so can be moved from room to room easily.

Shirley Pastore McCormack, Writer, Life/Wellness Coach, Registered Yoga Teacher

I use the Blue Max Lighting (BlueMax 70W dimmable) floor lamp. I use it 20 minutes each morning from the fall to spring equinoxes. I noticed a great level of improvement, but even more improvement when a doctor prescribed Vitamin D therapy. I was moderately to severely deficient, and needed 10,000 IU for 4-6 weeks under her care to bring my levels up. I do well with the light therapy as long as it is used in conjunction with regular daily doses of D3 (I’m now on 2000IU daily). The light therapy just seems to be “part of the whole solution.” (The company that makes this one is also Full Spectrum Solutions.)”

UPDATE: Jan 2024 – the above model, Blue Max Lighting floor lamp, is no longer available but a very comparable one is the Verilux® HappyLight® Duo – 2-in-1 Light Therapy & Task Floor Lamp.

Dr Josh Friedman, PHD, Integrative Psychotherapy of Omaha

I follow the guidelines of Columbia University’s Center for Environmental Therapeutics. They have done research on a variety of light boxes and the one on this page is inexpensive and effective [and is 10,000 lux] You can find it on Amazon here: Carex Day-Light Classic Plus Bright Light Therapy Lamp

This is what the Center for Environmental Therapeutics has to say about this newer light therapy device:

This handsome new bright light therapy unit ― the Carex Day-light “Classic” Plus Model supersedes our former Daylight “Classic” Model, presenting the same benefits at lower cost and with enhanced design. The required parameters for 10,000 lux light therapy have been thoroughly clinically tested at major university centers, and have been established as the international standard for treatment of winter depression, milder “winter doldrums,” and other chronobiological, circadian rhythm sleep and mood disturbances.

Using light therapy with amino acids or adjusting up the amino acids or doing both

Additional Jan 2024 updates:

I often recommend the use of light therapy in conjunction with amino acids. We may just add light therapy and keep amino acid dosing the same or we may use higher doses of amino acids like tryptophan, 5-HTP and GABA during the winter months. We may also do both depending on the person’s unique needs.

Here are some blog posts where I address adjusting up/increasing the amino acids during winter:

There may even be a seasonal aspect to PMDD/PMS with an increase in hormonal binge eating, wine drinking and anxiety – with symptoms ramping up from October (click here to read that blog post).

More binge eating, emotional eating and carb cravings in Winter

This paper, The Role of Diet, Eating Behavior, and Nutrition Intervention in Seasonal Affective Disorder: A Systematic Review discusses the eating and drinking habits of individuals with SAD (seasonal affective disorder):

Compared with non-clinical subjects, SAD patients tended to consume significantly larger dinners and more evening snacks during weekdays and weekends and exhibit a higher frequency of binge eating, external eating, and emotional eating. Additionally, compared to healthy controls, SAD patients presented more cravings for starch-rich food and food with high fiber.

This paper also mentions vegetarianism being associated with higher SAD prevalence. As outlined in my book (link below) and various blogs, I am an advocate of quality animal protein as it provides amino acids, zinc, iron, omega-3s and vitamin B12 – all needed for neurotransmitter production.

It also mentions that alcoholism is “associated with higher SAD prevalence.”

Amino acids and light therapy help emotional eating and excessive drinking

The authors don’t offer a solution but I can share that the amino acids mentioned above help with sugar/carb cravings and emotional eating and alcohol addiction.

Using light therapy is going to help too, with research suggesting that bright light therapy is potentially effective at improving both disordered-eating behavior and mood.

Seasonality to anxiety and panic disorder and how to use bright light therapy

There is a seasonality to anxiety and panic disorder just as there are seasonal variations in mood for certain susceptible individuals. You can read more about this and some of the basics like how to use bright light, and for how long, possible adverse effects and who should not use bright light therapy.

The blog is: How to use bright light therapy for increased anxiety, increased panic and SAD during the cold dark winter months
