Sunlight is essential to all living forms and when there is a lack of sunlight we tend to get diseased. One of the most important disorders is SAD (Seasonal Affective Disorder) which as the name suggests is a seasonal disorder that happens during the winter season. It is basically a type of depression.
The below-mentioned causes are just assumptive theories formulated by the scientists.
Vitamin D is formed in the body due to the exposure of sunlight. Since this disorder happens during the cold winter season, people with SAD experience depression with anxiety due to the less formation of vitamin D.
It is quite prevalent with people having a family history of depression or substance abuse.
During SAD, there is an abnormal circadian rhythm. It is basically the body clock that gets affected due to the change in the weather condition.
Due to the lack of sunlight, the hypothalamus function gets disturbed which affects the formation of neurotransmitters. There will be low levels of serotonin and high levels of melatonin.
This treatment is basically exposing oneself to a light for about 30 minutes a day after waking up in the morning.
This therapy when compared to the light therapy has been effective for a longer period of time.
If the above-mentioned therapies do not work out, then we can go for some lifestyle changing techniques that would combat in curing SAD.
It is one of the best lifestyle changes that the doctors could prescribe as it makes the mind clear and calm, taking care of the side effects of depression and anxiety.
Try out some outdoor exercises. The exercise can be a simple 15-minute exercise of walking that increases the serotonin levels produced in the brain. If it is very cold to go out, one can walk on a treadmill near the window.
Another fantastic exercise is the good practice of yoga.
SAD is actually the disorder that happens during the winter season, so anything that would make the person move away from the couch and have more movement of exertion would be very helpful.
