People experience different kinds of pain. There are different types of pain, but the more common type is physical pain. Injuries and diseases are some of the leading causes that result in physical pain. Physical pain can manifest through feelings of aching, burning, and throbbing.
However, people feel another kind of pain, which we don’t talk about as often. And that is psychological pain. Likewise the former, this type of pain can stem from several causes as well. But in this article, the focus is on seasonal affective disorder.
Seasonal Affective Disorder (SAD) is a type of depression induced by seasonal changes. SAD is also known as “winter depression.” People typically experience this condition during the fall and winter seasons where there is less sunlight.
People with SAD experience symptoms similar to that of major depression, which can interfere with daily functioning.
Symptoms include the following:
- loss of interest in activities
- loss of energy
- changes in sleep
- difficulty thinking
- suicidal thoughts
How does change in sunlight trigger SAD? Researchers have proposed several theories to explain this phenomenon. Decreased exposure to sunlight leads to a shift in people’s biological clocks. This shift affects the regulation of hormones, which in turn affects mood and sleep patterns.
One of the affected hormones is serotonin – the happiness hormone. Serotonin levels drop with decreased sunlight causing mood changes. Seasonal changes also affect melatonin, the sleep hormone. With a lack of sunlight, there is an overproduction of melatonin. As a result, people feel sleepier.
SAD’s link with sunlight exposure is mediated with light therapy.
