ELI5, why is going to bed super late bad for you if you still get the same amount of sleep?

584 views

I’ve always wondered this, espeically over summer break or for those who work later but why is going to bed late bad for you if you still get the perfect amount of sleep?

For example, last night I wen’t to bed at like 1:30 AM and woke up at 10:30 am, which is 9 hours? So if I’m getting required sleep, how is it bad for me?

It has been scientifically proven that working night jobs/shifts and sleeping from 10am-6am leads to high blood pressure/hypertension.

>overweight and obesity, increased triglycerides and total cholesterol levels. Disrupted sleep patterns may also influence the efficiency of the liver and the kidney. Night shift workers may also experience a greater risk of intoxication or retention of harmful substances.

Daytime sleeping is inherently less restful for non-nocturnal animals. And we are in every way that counts still animals.

On the one hand this doesn’t matter at all. But in the other hand many people find they don’t get good quality sleep during daylight hours. This could be a factor. Working night shift is known to be detrimental to your health and rotating shifts worse again. But not everyone is affected. If you are not affected then nothing to worry about..

It isn’t.
Society just made it unhealthy.

Because society is based on earlier hours, you will have to wake up early at some point. No matter how much you try, there’s always gonna be that one 8am appointment that you can’t reschedule.

This is basically the discussion of my life.
People try to tell me it’s not healthy, while many scientists have proven there really is such thing as people with a later circadian rhytm.

I’m 26, been trying to change my sleeping pattern for almost 10 years. Waking up early simply does not work.

If I wake up by 6am, I’m tired the whooooole entire day. By 9pm, I start gaining energy… And when it’s dark, I thrive.

People tell me all the time, that if I’d wake up everyday at 6am, my rhythm will change.
Tried it, guess what, after a weekend of not setting my 6am alarm anymore, I was a night owl again.

It’s not. The bad thing is going to bed when your body doesn’t want you to. Early or late, everyone has a circadian rhythm that their bodies adopt.

Some people are night owls. Trying to get them to sleep at 9 PM is misery. Some people are morning larks. They’ll fall over staying up until 1 AM.

Guess I’ll start a to-do list for my internal clock! Brush teeth, wash face, tackle world’s problems. No biggie.
