Can Vitamin D help you beat the winter blues?

Seasonal Affective Disorder (SAD), also known as the ‘winter blues’, is thought to affect an estimated 10 million Americans each year.

The facts about SAD

The precise cause of SAD is not fully understood, but the general consensus is that it is caused by a lack of sunlight, which leads to lower serotonin levels – the hormone that affects mood, appetite and sleep.

Those in the northern hemisphere are more susceptible as they experience large changes in ultraviolet light levels between the summer and winter. In the winter, the dark, gloomy weather can have a profound effect on our body clocks, resulting in an impulse for hibernation. Extended periods of darkness can cause us to eat more and be less energetic, making us feel lethargic and sluggish with physical activity an effort.

Treatments for SAD

Many people think that feeling down and tired is a normal part of winter, but there are natural ways to help ease the effects of SAD.

Boosting your vitamin D levels

Vitamin D supplementation is an easy and inexpensive way to help reduce the symptoms of SAD.

90% of our essential vitamin D must come from our skin's unprotected exposure to the sun, however during the winter months (October to March) the sun’s ultraviolet rays are not strong enough for the body to synthesize into vitamin D.

Taking a daily vitamin D supplement during this period to protect bone and muscle health, but this simple supplementation could also protect you against the effects of SAD.
