Question of the week #7

Take me through the night
Fall into the dark side
We don't need the light
We'll live on the dark side

Darkness and sleep:

These two things are interlinked. We sleep well in darkness because during that time the nerves & muscles remain inactive & seem like they are also sleeping. The absence of light sends a critical signal to the brain & body that let’s rest.

More importantly, the Melatonin hormone is released when we are in the dark. It is produced by the pineal gland in the brain. It regulates our internal clock & immune system, it is also a strong anti-oxidant.

Effect of dark vs light on sleep:

Light acts as a signal for our body to be awake like it says it’s time to wake up! While dark triggers the release of melatonin for deep sleep. Keep your bedroom dark, quiet & cool.


Almost every people at least one time in their life suffers through depression. And from the last year, the depression rate is increasing. And I know some of you are going through this phase. Sleeping in complete darkness lowers the risk of depression.

That’s why pitch-black darkness is essential for sleep.
