Seasonal Affective Disorder, Not Just the "Winter Blues"

/
seasonal affective disorder

If you've ever noticed that your mood seems to dampen during the fall and winter months, you may be experiencing Seasonal Affective Disorder, otherwise known as SAD. In fact, many people live with a mild form of SAD and don't even know it.

Symptoms
A form of clinical depression, SAD symptoms include: fatigue, lack of interest in normal activities, social withdrawal, carbohydrate cravings, and weight gain.

Unlike other mood disorders, SAD symptoms are associated with seasonal changes in light, often occurring only during the autumn and winter months, with the most difficult months being January and February. Outside of the winter months, SAD can be triggered by long stretches of cloudy weather or working year-round in a dark environment without natural sunlight.

Symptoms may vary in intensity. Any of these symptoms, alone or in tandem with one another, can have a serious effect on your quality of life.

Prevention & Management
With the right course of treatment, SAD can be a manageable condition. If you think you may be experiencing SAD or any other mood disorder, discuss your symptoms with Dr. Bossio to create an individualized plan for mood stabilization and enhancement. Ask Dr. Bossio about these four ways you can prevent and manage SAD.

1. Get as much sun as possible. Bundle up and take a walk, sit near a window at work, or participate in outdoor winter sports. However you choose to do it, exposing yourself to sunlight can help curb the symptoms of SAD.

2. Give phototherapy a try. Otherwise known as light therapy, phototherapy often uses a special fluorescent lamp to trick the brain into thinking the day is longer, and it has proven to be an effective treatment option for many. Just 30 to 90 minutes of daily exposure may have profound effects on your mood.

3. Increase your vitamin D intake. Although there is still insufficient evidence to conclude that vitamin D deficiency causes depression, cross-sectional studies have identified associations between depression and low vitamin D levels. Discuss intake of vitamin D supplements with Dr. Bossio.

4. Supplement with a healthy lifestyle. Additional ways to manage SAD include herbal remedies, homeopathy and other types of supplements. However, eating right, getting enough sleep, and exercising regularly are still the best ways to improve and maintain your psychological health year-round.

Vitamin D

Vitamin D - also known as the "sunshine vitamin" - is actually a hormone and an essential part of the human body. Throughout evolution, sunlight has produced vitamin D in the skin, but the advent of the electric light and sunblock, as well as a common fear of skin cancer, seem to have led to a mass vitamin D deficiency. In fact, the recommended daily intake (RDI) for vitamin D recently tripled, going from a recommended 200 IU (5 mcg) for adults up to 50 years of age to 600 IU (15 mcg) for those 1 to 70 years of age, based mainly upon bone health research.

A vitamin D deficiency can cause osteopenia, osteoporosis, increased risk of fracture, sunken pelvic area (due to rickets) and trouble getting pregnant and delivering a baby naturally.

Of the six forms of vitamin D, vitamins D2 and D3 have been identified as the most important for human nutrition. Vitamin D2 predominantly comes from the sun and fungi, such as mushrooms. Vitamin D3 can be produced in the body from the absorption and conversion of the sun's UVB rays or from animal sources.

Because vitamin D affects the entire body, it is vital to maintain your body's vitamin D levels. If you're looking for a vitamin D boost, try eating fatty fish, mushrooms, liver, egg yolks, milk, and yogurt. Better yet, get plenty of direct sun exposure. If you are concerned that your vitamin D levels are not up to par, talk to Dr. Bossio about an assessment and individualized plan.

Shedding Light on Phototherapy

phototherapy

Phototherapy, or light therapy, has shown promise in treating eczema, reducing itching skin, guarding against inflammation, increasing bacterial defenses in the skin, and increasing vitamin D production. It's also a unique therapy for treating Seasonal Affective Disorder. Phototherapy provides the body with the additional light it needs to stimulate the brain activity that controls circadian rhythms. Research suggests that the benefits may be heightened by undergoing light treatment as soon after waking up as possible. The therapy, which can be done in a clinical setting or at home using a special light box, may actually be as beneficial - or more so - than antidepressants. Symptoms typically improve within two weeks to two months of steady treatment.

How It Works
Phototherapy uses a light box to emit specific wavelengths of light, imitating sunlight, but avoiding exposure to harmful UVA rays. Generally, phototherapy light boxes provide 10,000 lux ("lux" is a measure of light intensity), which is roughly 100 times brighter than typical indoor lighting, but not as bright as a sunny day, which can clock in at 50,000 lux or more. Recent advances in light therapy include using light boxes that simulate sunrise, gradually increasing in intensity from darkness up to 300 lux. Another new therapy uses lower-intensity blue light, which has a more powerful effect on the retina than white light, tricking the brain into thinking it's brighter than it is.

Risks
However, phototherapy is not without risks. It can cause burns, increase signs of aging, and increase the risk of skin cancers if used regularly over long periods of time, or if administered using subpar equipment. Before investing time and money on phototherapy, discuss your concerns and needs with Dr. Bossio. He or she will be able to make a diagnosis and prescribe an individualized treatment plan for brightening your winter.

Because the FDA does not regulate light boxes, be sure to discuss your equipment options with Dr. Bossio, or phototherapy professional, before purchasing a light box. For more information on phototherapy, visit the American Psychological Association, the American Osteopathic College of Dermatology or the National Eczema Association.
