Have you woke up all night to watch your favorite show? All these reasons could lead to sleep deprivation and results in not properly functioning of your body and mind.



How People Get Sleepy?

We thankfully grow sleepy due to signals from our body telling us that we are tired. And signals from the environment telling us that it’s dark outside. The increase in sleep-inducing chemicals, like adenosine and melatonin, send us into a light doze that grows deeper, making our breathing and heart rate slow down and our muscles relax. This-REM sleep is when DNA is repaired and our body replenishes themselves for the day ahead.
