Staying up late does make you look older.
Also the lack of sleep and being sleep deprived and not getting the proper amount of sleep can make you look older, tired, saggy eyelids cause eye bags and even pale skin.
Lack of sleep causes you to not think properly, decreases your energy, causes you to hallucinate, reduces your reaction time, causes confusion, can cause you to have accidents, and eventually can cause you to die if you fail to get enough sleep.
Your body can also begin to ache from lack of sleep.
You can live with insomnia for a long time and even live a normal life expectancy.
However if you never sleep or sleep very little then it may shorten your life by around 10 years or so.
If you don't sleep at all then you can usually live for a week or 2 weeks before you die from lack of sleep.
Insomnia does not always cause death although if you don't get enough sleep it can cause an early death or if you don't sleep at all your body will eventually shut down and you can die from a complete lack of sleep.
If you don't sleep for 3 days your brain will start to suffer and you'll begin hallucinating, have poor reaction time, cannot remember things or learn new things and eventually you may get into an accident or get killed.
If you don't sleep for 3 days you will also be very limited in your ability to think, especially executive functions such as multitasking, remembering details, and paying attention.
And this level of sleep deprivation can make it difficult to see even simple tasks through to completion.
Without sleep your emotions are also affected.
You can survive on 2 hours a sleep a night but only for a short while.
People need at least 7 to 8 hours of sleep a night to stay healthy and to have enough energy during the day.
2 hours of sleep is not nearly enough and can result in accidents, health issues and eventually could lead to death.
With only 2 hours of sleep a night you'll not have enough energy and would likely hallucinate and not have a good reaction time.
If you have trouble sleeping try some melatonin, sleeping pills or even use some white noise or pink noise in the background to help you sleep.
Sleep is very important to your health and well being.
Black noise refers to complete silence.
Some people sleep better in complete silence which is known as black noise.
And some people prefer to sleep with some background noise going such as pink noise or white noise.
Pink noise is the sound that is best for sleep for most people.
White noise is also best for sleep.
I find white noise is best for me to sleep although some people find the pink noise the best sound for sleep.
It is OK to have white noise on all night.
Having white noise on all night can help you stay asleep so that you get a restful nights sleep.
I leave white noise on all night on my computer through YouTube and it plays all night and I sleep much better as a result of the white noise.
Leaving white noise on all night is OK and can help you sleep and stay asleep.
If you need white noise to sleep then it's perfectly fine to let the white noise play all night to help you get a restful nights sleep.
I leave white noise on all night myself and it helps me sleep much better.
To shut your brain down to sleep you should start by getting into a bedtime routine which helps your brain know when it's time to fall asleep.
Start by going to bed and winding down at the same time each night.
About 30 minutes to an hour before bedtime shut off the TV, electronics etc and try reading a good book.
If you still can't get to sleep then try taking some melatonin supplements which is a hormone that your body needs to help your brain shut down for sleep.
In some cases you may need to take some sleeping pills as well.
Also try ridding your mind of any worries and bad thoughts and try focusing on good thoughts.
Do breathing exercises as well to help you relax.
Older adults are more likely to take naps during the daytime due to age-related changes in circadian rhythms and sleep patterns.
The age at which you start needing less sleep is 20 years of age.
When you're first born you need lots of sleep and as you get older and older you need less sleep.
Newborns can sleep as much as 14 hours to 17 hours which is a lot but the newborns need that amount of sleep.
As the newborn grows they start needing less sleep.
As you age your body produces lower levels of growth hormone, so you'll likely experience a decrease in slow wave or deep sleep (an especially refreshing part of the sleep cycle).
When this happens you produce less melatonin, meaning you'll often experience more fragmented sleep and wake up more often during the night.
For adults the recommended number of hours is 7 to 9 hours, with 6 hours or 10 hours of sleep deemed appropriate on either side. It is not a good idea to get 6 hours or less of sleep
Sometimes life calls and we don't get enough sleep.
But five hours of sleep out of a 24-hour day isn't enough, especially in the long term.
According to a 2018 study of more than 10,000 people, the body's ability to function declines if sleep isn't in the seven- to eight-hour range.
Contrary to our quiet physical state, the brain is very active during sleep, carrying out many important functions.
Sleep is essential to every process in the body, affecting our physical and mental functioning the next day, our ability to fight disease and develop immunity, and our metabolism and chronic disease risk.
A number of chronic health conditions may be affected by not getting enough sleep on a regular basis.
These include high blood pressure, diabetes, heart failure, coronary heart disease and some cancers.
You may also be more likely to have a stroke. You're at greater risk of injury.
An insomniac is someone who experiences insomnia the inability to fall asleep or stay asleep for an adequate amount of time.
Insomnia is often used casually to refer to occasional sleeplessness or a single instance of it.
Insomnia is a sleep disorder in which you have trouble falling and/or staying
The condition can be short-term (acute) or can last a long time (chronic).
It may also come and go.
Acute insomnia lasts from 1 night to a few weeks.
Insomnia is chronic when it happens at least 3 nights a week for 3 months or more.
