Did You KnowGetting 10–15 minutes of sunlight daily is enough to prevent rickets and lift moods in most people. 

The light/dark cycle of the sun has a powerful effect on the circadian clock, sleep, and alertness.

Your body’s circadian clock responds to light, as a signal to be awake, and dark, as a signal to fall asleep.

However, the optimal duration varies based on many factors, such as time of day, geographical location, and skin color.

While many of us might not have access to sufficient sunlight, light therapy is an option.

It is equally effective in improving mental health. Light therapy, also known as phototherapy, involves exposure to an artificial light source.

Your house lights don’t replace natural light exposure or light therapy machines because the house lights are typically much dimmer.

You may not be able to tell because your pupils can adjust the light that you perceive.

However, various brightness levels affect your brain’s neurochemistry differently.

The therapeutic effect of light is mediated through the eye. However, one should avoid staring at the light unit directly.
