While some people regularly function on short periods of sleep, research mostly agrees that six hours of sleep is not enough for most adults. Experts recommend that most adults need at least seven hours of sleep every night.
A study has found that having either more or less than six to eight hours sleep a night could increase the risk of heart disease or stoke. Between six and eight hours was found to be the optimum amount of sleep.
A person experiencing segmented sleep will sleep for 6-8 hours but in two shifts during the night. Naps may be beneficial and be a more natural way of sleeping. The suggested benefits of naps include improved memory and learning ability, increased alertness, and an improved mood.
The bare minimum of sleep needed to live, not just thrive, is 4 hours per 24-hour period. Seven to 9 hours of sleep are needed for health, renewal, learning, and memory. Disruption of the sleep cycle from shift work creates problems for the quality and quantity of sleep.
This is because our brain is constantly forming new connections while we are awake. The longer we are awake, the more active our minds become. Scientists believe that this is partly why sleep deprivation has been shown to reduce symptoms of depression. However, there are negative outcomes of this, too.
Getting only six hours of sleep each night is considered a poor sleep schedule that can result in sleep deprivation and lead to poor mental health and potential sleep disorders. You can survive on six hours of sleep but that would not be good for your long-term health.
Only getting five hours of sleep affects a person's daytime functioning, sense of well-being, and both their mental and physical health. Though one night of insufficient sleep has consequences, the effects of sleep deprivation are cumulative.
We do not recommend sleeping for only one hour at night. Some research suggests that lost sleep can take years off your life and that you may not be able to catch up on the lost hours of rest.

So when you're getting eight hours and still feeling tired the next day, it's frustrating.

“There is no such thing as a “fixed or ideal time” to go to bed which will suit all individuals. It is generally advisable to fall asleep between 10 pm to midnight as for most people this is when the circadian rhythm is at a point that favours falling asleep.”
So why do people think they are able to function optimally on 6 hours of regular sleep? This is because of a natural human phenomenon known as 'renorming'. Renorming means that we are only able to compare how we feel today to how we felt yesterday or the day before.

The good news? You can function on 5 hours of sleep, but that shouldn't be your norm. Some people, appropriately called short sleepers, just don't need a lot of sleep. In fact, they're at their max with less than 6 hours a night.
Unfortunately, most people cannot have a healthy lifestyle with only four hours of sleep, research suggests. However, personal and anecdotal evidence supporting shorter sleep by using polyphasic sleep suggests otherwise. This means that we cannot say for sure if you can thrive on four hours of sleep.
According to the Center for Disease Control and Prevention, teenagers need 8-10 hours of sleep, while adults 18-60 need 7 hours in a 24-hour period.
Yes, it is. And sleeping too much — 10 hours or more — can harm your health. Further, it may be a sign of underlying health problems, according to a study by the Centers for Disease Control and Prevention (CDC) published by the American Academy of Sleep Medicine.
Another reason why you might not feel particularly tired after a night, or several nights, of short sleep is due to a surge in your cortisol levels (a stress hormone that boosts alertness) the next day.
