How Presence Or Absence Of Light Triggers Insomnia

Posted on October 22, 2008 in Latest News

Insomnia is being related to several causes such as hormonal fluctuations, depression, and stress etc. Though these are major causes, they are something very common and is known to most of us.

How many of us knew that presence or absence of light trigger insomnia in many of us. Many a times we notice that we stop being asleep when someone comes into the room we are sleeping in and switches on the light. And no matter how much we try, we cannot fall asleep after that.

Some on the other hand cannot sleep at all when the light is on. Also, some of us would notice that we tend to fall asleep when the lights are dimmed either in a theatre or while watching some seminar.

Strange but true, lighting does play a major role in determining the quality of sleep we have. According to experts, our eyelids have cells that are very sensitive to light and play an important role in triggering the production of melatonin, that further calms the body and induces sleep.

Only in the presence of dim light or no lights is melatonin being produced in the body. This further stresses the need for one to switch off or dim the lightening in order to be able to sleep.

This aspect can help many people suffering from insomnia, as unconsciously or consciously we tend to ignore his factor and tend to have a disrupted sleep by having the lights switched on and off while sleeping.
