Question

What is the demirts of wake up late in night ?

Answer 1

Our body has a natural circadian rhythm, which controls the timings of all the physiological processes happening in your body. It is a 24 hour cycle, and influences everything in your body; be it testosterone secretion, melatonin secretion, blood pressure rise, anything.

Now, to explain the whole concept of sleep I need to tell you what melatonin is. In layman terms, lets just say it is the hormone in humans and animals which regulates sleep and wakefullness.

Now, the above is a circadian cycle which is operating at it's normal condition. We can see that melatonin secretion starts at 9pm. So, in a person whose circadian rhythms are working in perfect condition, He/She will start to feel sleepy at 9pm. He/She will also wake up at 6- 6:30, since that is the time of peak blood pressure and cortisol release.

If you don't know what cortisol is, just know that it is a hormone released by the adrenal glands in response to stress in our body. Elevated cortisol levels indicate that a person is living a stressful lifestyle, but high-ish levels in the morning enable us to wake up.

But this circadian rhythm can be disturbed by many external and environmental factors.

Electronic devices emit blue light, which can significantly affect Melatonin production, which can further affect your sleep. Furthermore, sleeping late too often can ‘convince’ your circadian rhythm to go out of whack.

This explains everything which happens when we don't get enough sleep. If we sleep late, we have to wake up late to compensate; this is not possible for all people since they have to go to work. So, our patterns of testosterone rise, cortisol rise, everything; goes out of cycle.

Just to clarify, these effects will not be noticeable immediately. Your circadian rhythm won't go haywire just because you slept 10 minutes past 10pm. All these changes take place after a while.

Hey buddy here is ur answer !!


Many people sleep late and wake up late.

It normally messes up with your quality of sleep as you may miss natural deep sleep cycle.

Humans are very adaptive so it is possible that you move your sleep cycle to a different time but it will still not be synced with solar cycle.

It is known scientifically that changing your sleep timing will affect you at molecular and genetic level.

Certain genes are not expressed when we don’t sync with solar cycle
