Sleeping for 5 hours is enough

Sleeping for 5 hours is enough

Habitual sleep deprivation is associated with diverse and far-reaching health effects and none of them is good.

Between 7 and 9 hours of sleep per night are recommended. You can get used to less sleep, but you’re getting used to being miserable.

Cellphones, tablets, and all kinds of personal electronics are not a good idea when you’re getting ready for bed.

Researchers have increasingly focused on “blue light” emitted by screens and its effect on sleep and negative sleep-related health outcomes.

Our bodies tend to follow a natural rhythm of wakefulness and sleep that is attuned to sunrise and sunset for a reason.

While some missed sleep here and there isn’t necessarily a big deal, shifting your sleep schedule long term isn’t healthy.

It is not as good as sleeping. 

Everything from your brain to your heart to your lungs functions differently when sleeping compared to being awake. If you know you’re awake, the rest of your body does too.

A healthy sleeper actually takes a couple of minutes to fall asleep. We do see that if people fall asleep right away, that can be a sign that they are not getting quite enough sleep.

A Pernod digestif after dinner. A nip of brandy before bed. Whatever your poison, it won’t help you sleep any better. In fact, it will likely make you feel worse the next day and is also dangerous.

A nightcap can also cause sleep apnea or make it worse.

As much as we’d like to think we can train our bodies to need less sleep, the science says the opposite.

All of the evidence shows, without a shadow of a doubt, that chronic insufficient sleep, of five-six hours or less, is associated with a host of unfavorable consequences.

Loud snoring is actually one of the most common symptoms of sleep apnea, a disorder in which an individual can actually stop breathing while asleep.

Sleep apnea affects the quality of sleep. So if you snore loudly and you suffer from fatigue or sleepiness during the day, those symptoms together could mean you have it.

Snoring can be harmless, but it can also be a sign of the disorder sleep apnoea.

This causes the walls of the throat to relax and narrow during sleep, and can briefly stop people breathing. People with the condition are more likely to develop high blood pressure, an irregular heartbeat and have a heart attack or a stroke. One of the warning signs is loud snoring.

... opening the window, or turning on the air conditioner are effective ways to stay awake when driving.

These "aids" are ineffective and can be dangerous to the person who is driving while feeling drowsy or sleepy. 

It's best to pull off the road in a safe rest area and take a nap for 15-45 minutes. Caffeinated beverages can help overcome drowsiness for a short period of time. 

To really find out what your individual sleep needs are, do the following experiment for at least two weeks:

  • Pick the same bedtime every night.
  • Turn off your alarm.
  • Record the time you wake up.

You may sleep longer during the first few days, but over the course of a few weeks, a pattern will emerge of how much sleep your body needs each night.
