You Might Not Need As Much Sleep As You Think

How much sleep do you really need? (S1) | The Power of Good Health
  • Fitbit researchers compared how much people slept with their scores on Think Fast, an app Fitbit offers on its smartwatches.
  • Fitbit researchers find that people who slept an average of 5 hours and 50 minutes to 6 hours and 30 minutes per night performed better on the test than people who slept more or less.
  • In both men and women over age 40, reducing the amount of time spent awake at night increases cognitive performance by 10 percent.

You might not need as much sleep as you think, but you might need better sleep.

Using sleep data from its wearable devices, Fitbit researchers compared them to users’ scores on Think Fast, an app Fitbit offers on its smartwatches. They found that people who slept an average of 5 hours and 50 minutes to 6 hours and 30 minutes per night performed better on the test than people who slept more or less. These amounts are shorter than what doctors typically advise. Public health officials and physicians have long recommended adults sleep for at least seven hours, if not more, each night. They’ve become increasingly vocal about this as people work longer hours and spend more time in front of screens before bed.

Fitbit research scientist Jonathan Charlesworth said these guidelines are based on how much time people spend in bed as opposed to how much time people actually sleep. However, he said even Fitbit’s numbers are just averages, and the numbers can vary per person, especially based on factors like age and gender.

What Is Good Sleep

In addition to quantity, the quality of sleep you get is important. Tossing and turning in bed for 12 hours wont be as good for you as seven uninterrupted hours of sleep.

Quality sleep needs to be of adequate duration, restorative so you feel energized in the morning, consolidated and at appropriate times, St-Onge said. That means you need several continuous hours of restful sleep each night.

Ideally you want to go through multiple cycles of all five sleep stages. The stages start with feeling drowsy and advance through deeper sleep until you reach rapid eye movement or REM sleep when your brain is the most active and dreaming occurs. Its during this stage that learning and memory are affected.

Interaction Of Mental Health Conditions

Many mental health conditions dont arise in isolation instead, co-occurring conditions may influence one another as well as a persons sleep.

For example, it is not uncommon for people to experience both depression and anxiety, and people with both conditions have been found to have worse sleep than people with just depression or anxiety. These conditions also influence other important aspects of well-being, such as perception of pain, a process that may also influence the risk of sleeping problems.

How Much Sleep Is Too Much

However, if youre regularly sleeping more than nine or 10 hours per night, and you still feel tired during the day, thats a sign youre oversleeping. Around 8% to 9% of people oversleep, with women being more likely to do so than men.

Impaired Brain Functioning And Mental Health

At night, make your bedroom as dark, cool, and quiet as you can. Then, in the morning, use light strategically to wake yourself up. You may find it beneficial to use a dawn simulator as an alarm clock and open window curtains to let in the sunlight.

A good nights sleep is beneficial for your health, but a long nights sleep isnt necessarily better. Consider what may be contributing to your need to oversleep, and consult your doctor for their advice.

Sleep Is An Instant Mood Improver

Did you know 25% of Indians over the age of 15 have difficulties sleeping on a regular basis, and 2 million Indians suffer from insomnia? According to a new research, people with insomnia release more stress chemicals than others. This causes their bodies to become hyper-aroused, making it difficult for them to relax. Inability to sleep leads to increased tension, which can have serious consequences.

Sleep deprivation can cause depression, which can lead to insomnia. More and better-quality sleep, on the other hand, can help you feel elated.

Why Don’t Teens Get Enough Sleep

Teens often got a bad rap for staying up late, oversleeping for school, and falling asleep in class. But teen sleep patterns are different from those of adults or younger kids.

During the teen years, the body’s rhythm is reset, telling a person to fall asleep later and wake up later. This change is likely due to the brain hormone , which is released later at night for teens than it is for kids and adults. This can make it harder for teens to fall asleep early.

Changes in the body’s circadian rhythm coincide with a busy time in life. For most teens, the pressure to do well in school is more intense and it’s harder to get by without studying hard. And teens have other time demands everything from sports and other extracurricular activities to working a part-time job. Using electronics including phones, tablets, and computers also makes it hard to fall sleep. Many teens are up late texting friends, playing games, and watching videos.

Early school start times also play a role in lost sleep. Teens who fall asleep after midnight still have to get up early for school, meaning that they might squeeze in only 6 or 7 hours, or less, of sleep a night. A few hours of missed sleep a night may not seem like a big deal, but it can create a noticeable sleep deficit over time.

  • Consider learning a relaxation technique to help you wind down in readiness for sleep.
  • Avoid having any food or drink that contains caffeine after dinnertime. This includes coffee, tea, cola drinks and chocolate.
  • Avoid recreational drugs as they can cause you to have broken and poor quality sleep.
  • See your GP if self-help techniques dont increase your nightly sleep quota.

Sleep Experts Close In On The Optimal Night’s Sleep

How much sleep do you really need?

Experts generally recommend seven to nine hours a night for healthy adults. Sleep scientists say new guidelines are needed to take into account an abundance of recent research in the field and to reflect that Americans are on average sleeping less than they did in the past.

Several sleep studies have found that seven hours is the optimal amount of sleepnot eight, as was long believedwhen it comes to certain cognitive and health markers, although many doctors question that conclusion.

Other recent research has shown that skimping on a full night’s sleep, even by 20 minutes, impairs performance and memory the next day. And getting too much sleepnot just too little of itis associated with health problems including diabetes, obesity and cardiovascular disease and with higher rates of death, studies show.

“The lowest mortality and morbidity is with seven hours,” said Shawn Youngstedt, a professor in the College of Nursing and Health Innovation at Arizona State University Phoenix. “Eight hours or more has consistently been shown to be hazardous,” says Dr. Youngstedt, who researches the effects of oversleeping.

Is Six Hours Of Sleep Enough

In this fast-paced life that we live, many people only get 6 hours of sleep because of their busy schedule. We realize that there are not enough hours in the day for us to be able to do all of the work that we have, and that we often compromise our sleeping hours just to get things done. Some do take a nap in between tasks to help restore their low energy levels, but its never enough it seems to recoup the insufficient sleep that we get every night.

Some people think that they are sleeping well, only to find that they barely got seven hours in bed. You may argue that the number of hours doesnt really matter because there are some who can function with 6 hours of sleep alone. Unfortunately, there are a lot of people who dont realize the impact of having a good nights sleep, let alone the symptoms that accompany sleep deprivation.

For those who wonder, is 6 hours of sleep enough?, the answer to this is it depends. Although some people do well on 6 hours of sleep, many of them do not feel any better compared to those getting up to 8 hours of rest. They might not even realize how bad they feel. The problem lies in the fact that their body thinks that this already is the new normal for them, but little do they know that the side effects of being deprived of your much-needed sleep are already being felt in the form of mood swings, low energy levels, daytime sleepiness, and weight gain too just to name a few.
