Depression Triggered by Less Sun for Individuals with SAD
Brighter lights at home may help enliven someone’s mood during the gloomy winter season.
A number of people with depression have reported to struggle more in managing their condition during winter. This fits the profile of people suffering from SAD or seasonal affective disorder which usually triggers depression during autumn and early winter. There have also been documented cases of individuals being more prone to depression during the summer months.
A study in the United States shows that around 4 to 6 percent of the population is suffering from seasonal affective disorder. A Cleveland health facility cites that around 10 to 20 percent of the population may struggle with more mild winter depression. SAD is a common occurrence with individuals between the ages of 20 and 40 years old.
Some experts are also looking at the genetic reasons why a person is vulnerable to suffer from SAD.
A study by Provencio is looking at the possibility of gene mutation at the human eye genome that makes one more sensitive to light. Melanopsin was identified as the photopigment gene which helps people detect colors.
Knowing more about melanopsin will be able to help experts determine which people are more prone to SAD and which of these patients will respond positively to light therapy.
An experiment among 220 people concluded that the relation between light and SAD is consistent with known concepts about genetic vulnerability to certain health problems.
Aside from light and genes, other biological factors may play a major role in SAD. Experts point out to the circadian rhythm or the body clock, body hormones like serotonin and melatonin, and geographical location.
Experts suggest going for a consult if you think you are suffering from SAD. Some cases may respond well with light therapy, antidepressants, or some through exercise. Whatever may help, don’t ever give up on the fight against a depression!
