Seasonal affective disorder contributes to weight gain in the winter months
by Mike Adams, the Health Ranger, NaturalNews Editor
Seasonal affective disorder (SAD), a mood disorder associated with light variations, could be one of the main factors that lead to weight gain in the colder months, according to responsesource.com.
Ask anyone why people tend to put weight on in winter and they will generally put it down to the cold.
Before the days of central heating it made sense to add an extra layer of fat to protect us from the cold and it seems that we are still programmed to do so.
But whilst a lot of us blame the cold for our craving for casseroles, it seems that the dark winter days may be the culprit.
Depression due to lack of sunlight over the winter months has been talked about for years.
Many people are aware that it can cause depression, lethargy and disruption of sleep.
It is thought that the lack of daylight leads to a decrease in Serotonin, a neurotransmitter which is responsible for promoting feelings of relaxation and happiness in the brain.
Lack of Serotonin can not only lead to depression but also to cravings for sweet foods and starchy carbohydrates, driving us to the doughnuts and dumplings in a bid to stave off hunger and lethargy.
Light treatment or phototherapy has been recognised as an effective treatment for SAD for many years.
The treatment is delivered through a light box, a compact unit which simulates daylight by emitting 10,000 Lux of light.
The light box is able to provide adequate light to alleviate symptoms of SAD after only 30 minutes use per day.
As UV light does not seem to be essential for alleviating SAD symptoms, harmful UV waves are blocked, ensuring maximum light treatment benefits without the risk of damage to skin and eyes.
Mark Golding, a former SAD sufferer has first hand knowledge of the effectiveness of light therapy.
He says: "I found out about SAD and light therapy after months of feeling tired and demotivated.
