Is 6 Hours Of Sleep Enough For You? Here's What You Need To Know

With the hustle and bustle of modern life, it's not surprising that many people find it challenging to get enough sleep. After all, there are merely 24 hours in the day, and with work, family, and social obligations taking up so much time, it can be tough to find time to catch some Zs.

But how much sleep do you really require? Does it vary depending on your age, lifestyle, or health condition? And what are the consequences of getting poor sleep?

Let's take a closer look at these questions, other interesting facts, and tips.

How Much Sleep Do You Need?

Most researchers agree that adults require 7 to 8 hours of sleep daily. However, there is some difference depending on age. As mentioned by the Centers for Disease Control and Prevention, these are the recommended time of sleep for each age group recommended by the National Sleep Foundation;

Newborns (0-3 months)

Newborns require 14 to 17 hours of sleep per day, which means they generally sleep for two to four hours at a time.

Infants (4–12 months)

Infants require about 12 to 16 hours of sleep each day, which means they usually sleep for about 3 to 5 hours at a time.

Toddlers (1–2 years)

Toddlers require about 11 to 14 hours of sleep each day, which means they usually sleep for about 3 to 5 hours at a time.

Preschoolers (3 - 5 years)

Preschoolers require about 10 to 13 hours of sleep each day, which means they usually sleep for about 3 to 5 hours at a time. However, some preschoolers may get only one long good night's sleep.

School-aged children (6 - 12 years)

School-aged children require about 9 to 12 hours of sleep each day. They are often able to sleep through the night without waking up.

Teens (13 - 18 years)

Teenagers need 8 to 10 hours of sleep per day. However, many teens do not get enough sleep because of early school start times, homework, extracurricular activities, and part-time jobs.

Adults (18+)

Adults need 7 to 8 hours of sleep per day. However, many adults do not get enough sleep because of work, family, and social obligations.

Furthermore, many elderly people do not get enough sleep because of health conditions such as arthritis or incontinence.

Did You Know? Sleeping is an indicator of good health. If you aren't getting enough sleep, it could be a sign of a health issue.

Are You A Short Sleeper?

Natural Short Sleeprs sleep for less than 6 hours per day in a post about Is 6 Hours Of Sleep Enough

Although the recommended time frame for most adults is seven to eight hours per 24 hours, most adults do not get sufficient sleep of at least seven hours because of their busy lifestyles. This is alright in most cases, but if you consistently don't get enough sleep, it may be a sign of a sleep disorder.

However, there is another group called "Natural Short Sleepers." You might have met some people who sleep incredibly short hours, like 3-5 hours per day, and still feel rested. They don't have any underlying health conditions; they just have a difference in their genes.

There are two types of short-sleepers: those who need less than six hours of sleep each day and those who need less than five. According to several pieces of research, only three genes have been identified that control our natural sleep cycles: DEC2, ADRB1, and NPSR1.

UCSF explains that Mutation of DEC2 and ADRB1 causes a person to need only about five to six hours of sleep, while mutation of NPSR1 results in a person needing only four to 5.5 hours of sleep.

Interestingly, people with a mutation in NPSR1 have no memory deficits or other health problems caused by sleep deprivation. So, as you see, if you don't get at least 6 hours of sleep per day and are still doing fine, you might be a natural short-sleeper!

That being said, only a fraction of the population (about 1-3%) are natural short-sleepers. So, if you're not one of them, there's nothing to worry about.

Biological Sleep Needs

People have a circadian rhythm that tells their bodies when it is time to sleep in a post about Is 6 Hours Of Sleep Enough

Just because experts say that seven to nine hours of sleep is enough for most adults doesn't mean that's what your body needs.

Many factors can affect how much sleep you need, including;

  • Age: As you age, you need less sleep. This is because your body's circadian rhythm (the "body clock" that tells you when to sleep and wake up) changes as you age. Your sleep pattern also changes as you age. For example, older adults wake up more at night and have more difficulty falling and staying asleep.
  • Genes: As we discussed earlier, some people are natural short-sleepers and need less than six hours of sleep. However, most people need at least seven hours of sleep.
  • Gender: Generally speaking, women need more sleep than men. This is because women's brains are more complex and use more energy than men's.
  • Pregnancy: Pregnant women need more sleep than non-pregnant women. This is because their bodies are working overtime to support the growing baby.
  • Sleep disorders: If you have a sleep disorder, you may need less sleep than people who don't have a sleep disorder. For example, people with insomnia often need less sleep than people without insomnia.
  • Stress: If you're stressed, you may need less sleep than people who aren't stressed. This is because stress can lead to insomnia.

A peer-reviewed study about "Individual optimal sleep duration and potential sleep debt" reveals an average of 8.5 hours of sleep per day is the norm for most healthy adults.

So, as you see, although the minimum suggested time frame is 7 to 8 hours, many individuals may need more than that to function at their best.

Signs And Symptoms Of Sleep Deprivation

Sleep deprivation can impact your mental and physical health in a post about Is 6 Hours Of Sleep Enough

You may suffer from some or all of the following signs and symptoms if you aren't getting enough sleep:

  • Irritability
  • Fatigue
  • Brain fog
  • Tension headaches
  • Anxiety
  • Depression
  • Muscle aches
  • Confusion

Sleep deprivation can lead to serious health problems, including heart disease, stroke, hypertension(high blood pressure), obesity, and diabetes, as explained in a book about Sleep Disorders and Sleep Deprivation published by the NIH. Therefore, it's crucial to get help if you're sleep-deprived.

Is 6 Hours Of Sleep Enough?

Is Only Six Hours Sleep Time Enough For an Adult in a post about Is 6 Hours Of Sleep Enough

Despite the recommendation of the CDC, experts have argued that 6 hours of sleep may be enough for some people. A study by the University of California, San Diego showed that a 6-hour sleep schedule could benefit some people.

The study found that those who sleep for 6 to 7 hours per day have a better survival rate than those who sleep less or more than 6 to 7 hours. The study also found that those who sleep for 6 hours have a lower risk of death than those who sleep for 8 hours.

However, it's important to note that the study only found an association between sleep and mortality of women, not a cause-and-effect relationship.

Another scientific study by UCSF called "Short Sleepers Are Four Times More Likely to Catch a Cold" found that people who sleep for less than 6 hours are more likely to catch a cold than those who sleep for 7 hours or more. These studies suggest that 6 hours is the sweet spot for sleep duration. However, it is essential to note that every person is unique, and there is no one-size-fits-all solution for sleep.

Tips To Get A Good Night's Sleep

Tips To Get A Better Sleep in a post about Is 6 Hours Of Sleep Enough

To get a restful sleep, you should get a fair amount of deep and REM sleep. If you fall asleep while watching TV or working on the computer, you're not getting quality sleep.

Following a sleep schedule will help your body get into a sleep rhythm. It's essential to go to bed and wake up simultaneously every day, even on weekends.

Avoid Caffeine And Alcohol Before Bedtime

Caffeine and alcohol can disrupt your sleep. Caffeine can linger in your system for up to 8 hours, so avoid it at night. Though alcohol can make you sleepy, it can also disrupt sleep.
