“The amount of sleep required by the average person is five minutes more.”-Wilson Mizener
Every human has an internal clock which we refer as circadian rhythm. The biggest environmental cue our bodies recognize, and react to, is light. The regulation of our bodily systems based on time of day is referred to as our circadian rhythm. The definition for circadian rhythm as per National Institute of General Medical Science(NIGMS) is
“… physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment. They are found in most living things, including animals, plants and many tiny microbes.”
Circadian rhythm, also referred as body clock in layman’s term, is governed by the 24-hour pattern of the earth’s rotation. These rhythms influence body functions such as blood pressure, body temperature, hormone levels, and heart rate, all of which play a role in your body’s readiness for exercise.
[N.B :Circadian clock should not be confused for biological clock.]
The most accurate answer to how much we human being need to sleep lies in the fact on the quality of the sleep. This is what some folks like to call as “sound sleep”. You get a sound sleep when you can atleast get 4 hours of deep sleep.
Medically, sleep is slipt into 5 different stages. (Stage 0 to Stage 4). Stage 0 being the ‘Awake’ state and Stage 4 being the ‘Deep Sleep’ stage. If we are able to manage the deep sleep stage atleast between 3-4 hours, then we are in good shape.
Today, its pretty easy to find out the quality of your sleep. To know more about how you can assess the quality of your sleep, you can visit my blog on the same at ______
