Normative Sleep Duration Values Across The Lifespan

How many hours of sleep do you need (Best sleeping time for good health)

Sleepwake regulation and sleep states evolve very rapidly during the first year of life. For example, newborns do not have an established circadian rhythm and therefore their sleep is distributed across the full 24-hour day. At 1012 weeks, the circadian rhythm emerges and sleep becomes more nocturnal between ages 4 and 12 months. Children continue to take daytime naps between 1 and 4 years of age, and night wakings are common. Daytime naps typically stop by the age of 5 years and overnight sleep duration gradually declines throughout childhood, in part due to a shift to later bedtimes and unchanged wake times.

Sleep patterns are explained by a complex interplay between genetic, behavioral, environmental, and social factors. Examples of factors that can determine sleep duration include daycare/school schedules, parenting practices, cultural preferences, family routines, and individual differences in genetic makeup. Despite inter-individual differences in sleep duration, international normative data exist to show the normal distribution of sleep duration for different age groups. However, it is important to keep in mind that normative reference values by no means indicate anything about what the ideal or optimal sleep duration should be, ie, the amount of sleep associated with health benefits. Nevertheless, they tell us about what is normal in the population and provide a valuable yardstick for practitioners and educators when dealing with sleep-related issues.

Conducting A Sleep Hygiene Check

If youre keeping a sleep diary as a personal initiative, you can use it to benefit your health by conducting a check-in.

As you review your sleep diary, a handful of questions can help you evaluate your sleep:

  • Am I budgeting enough time for sleep?
  • Is my sleep schedule consistent or full of fluctuations?
  • Am I spending significant time lying in bed without being able to fall asleep?
  • Is my sleep disrupted in the night? If so, is there any pattern in the diary that might explain why?
  • Is my sleep satisfying? Do I feel drowsy during the day?
  • Am I taking naps that are too long or too late in the day that could be affecting my nighttime sleep?
  • Is my use of alcohol, caffeine, and/or medications affecting my sleep time or sleep quality?

As you go through these questions, you can identify opportunities to apply practical tips to boost your sleep hygiene and contribute to your overall wellness.

Improve Your Sleep Today: Make Sleep A Priority

Once you have a nightly goal based on the hours of sleep that you need, its time to start planning for how to make that a reality.

Start by making sleep a priority in your schedule. This means budgeting for the hours you need so that work or social activities dont trade off with sleep. While cutting sleep short may be tempting in the moment, it doesnt pay off because sleep is essential to being at your best both mentally and physically.

Improving your sleep hygiene, which includes your bedroom setting and sleep-related habits, is an established way to get better rest. Examples of sleep hygiene improvements include:

  • Sticking to the same sleep schedule every day, even on weekends.
  • Choosing thebest mattress that is supportive and comfortable, and outfitting it with quality pillows and bedding.
  • Minimizing potential disruptions from light and sound while optimizing your bedroom temperature and aroma.
  • Disconnecting from electronic devices like mobile phones and laptops for a half-hour or more before bed.

Sleeping Well Staying Healthy

While sleeping well is no guarantee of good health, it does help to maintain many vital functions. One of the most important of these functions may be to provide cells and tissues with the opportunity to recover from the wear and tear of daily life. Major restorative functions in the body such as tissue repair, muscle growth, and protein synthesis occur almost exclusively during sleep.

Many other conclusions about the role sleep plays in maintaining health have come from studying what happens when humans and other animals are deprived of the sleep they need. For example, scientists have discovered that insufficient sleep may cause health problems by altering levels of the hormones involved in such processes as metabolism, appetite regulation, and stress response.11,12,13 Studies such as these may one day lead to a better understanding of how insufficient sleep increases disease risk.

How To Determine The Minimum Sleep Time Required For An Individual

It is very simple to determine the minimum sleep time that you require for healthy and happy living. Just ask yourself these three questions:

  • How long do you take to fall asleep after hitting the sheets?
  • Do you rely on an alarm clock to wake up every morning?
  • How do you feel the whole day after having the minimum number of hours of sleep you have allotted for yourself?
  • If you take no time to sleep once you hit the bed or if you need an alarm clock to wake up every morning or if you are feeling fatigued, anxious and are having mood swings during the day, all these symptoms denote that you need more sleep and the minimum sleep time that you have set for yourself is not enough for your body to get complete rest.

    The best decision is to set a sleep diary and note every detail, which in turn would help you determine how many hours of sleep you require to feel fresh and fit the next day.
