The Science behind Sleep

Ever wondered why do we feel sleepy at times and not at other? Here is how our body functions and realize the need for sleep. Our body functions according to its natural clock which is of 24 hours duration. It is called Circadian clock and helps the body to regulate sleep cycle. External factors such as lights effect these circadian rhythms. This is the reason we feel sleepy at night usually and not the day time. Light signals pass through eyes and inform the brain that it is day time. Brain then arranges your body clock according to this information.

When it is day time body releases adenosine hormone, it keeps on increasing as the day passes and is at its peak at the end of the day. This adenosine accumulation leads to the feeling of Sleepiness. When we sleep, body breaks down the accumulated adenosine. Another hormone that is equally responsible in sleep cycle is melatonin which is released at its peak when its dark. This indicates our body that its time for sleep by giving us the drowsiness feeling.

Another process responsible for sleep is Sleep drive. The sleep drive increases with every hour after we wake up. By the end of the day the sleep drive is maximum and works along with Cicardian Rhythm to give a good night sleep.
