Seattle Residents May Be More Susceptible to Seasonal Depression

with 3 comments

The epic winters and rains experienced by Seattle are known to cause depression in a large percent of the population. Why? Research has shown that sesonal depression, also known as Seasonal Affective Disorder, or SAD, is linked to a lack of a Vitamin D3.

Vitamin D3cholecalciferol – is the form of Vitamin D that is obtained through human exposure to direct sunlight. It is considered to be superior to other forms of Vitamin D such as ergocalciferol, which is better known as Vitamin D2.

Vitamin D3 SunResearch has shown that people in cold, rainy climates, are more susceptible to Vitamin D Deficiency, which has been scientifically linked to Seasonal Affective Disorder. This means that people who live in places like Seattle, Washington, where the climate is often rainy and generally cold, are more likely to suffer from SAD, which is a type of seasonal depression that occurs primarily during the winter months.

Take this passage from an earlier post about Vitamin D Deficiency appearing on this site:

A scientific link between low Vitamin D3 levels and depression has been established following several recent studies confirming the relationship. According to one such study by scientists at Georgia State University: “The likelihood of having depression in persons with vitamin D deficiency is significantly higher compared to those with vitamin D sufficiency. Early diagnosis and intervention are paramount because coexistence of vitamin D deficiency and depression has serious negative consequences on health.” (Source)

There has been a surge of interest the medical research community concerning Vitamin D3. Dr. Michael Holick of Boston University School, one of the world’s leading experts on the topic, has been quoted as saying “You’re more likely to live longer and you’re less likely to die of serious chronic disease if you have adequate vitamin D on board. It may well be the most important nutrient of the decade.”

There is also current research being conducted on Vitamin D3 at the Mayo Clinic, the Fred Hutchinson Cancer Research Center and The U.S. Institute of Medicine to name a few. Existing research has already linked Vitamin D Deficiency to at least 32 different diseases, illnesses and various other health ailments.

People who live in northern climates that are cold and/or rainy have limited opportunities to obtain Vitamin D from sunlight. It is recommended that these individuals in particular take high-quality Vitamin D3 Supplements in order to prevent Vitamin D Deficiency.

  2. How much sunlight is the right amount? Too little and no vitamin d, too much and skin cancer? Also, does sunblock also stop you from making vitamin d?

  3. As with all things, moderation is the key to longevity. Sunblock does indeed inhibit vitamin D absorption. It depends on other factors as well, such as how much clothes you’re wearing. Skin tone plays a role as well. The darker the skin, the lower the absorption rate. Without knowing your skin tone, your specific needs and where you reside, it would be impossible to answer your question other than to suggest having your levels tested and asking your doctor (and hoping/praying he/she is a good doctor. Trusting your own judgment isn’t a bad idea for most people (only you know that).
