How Long Should We Sleep To Be Healthy?



Do you sleep less and wake up tired every day? You're not alone. At least a third of adults sleep less than seven hours a night on average. Lack of sleep can cause various problems during the day, so how long should we sleep to be healthy?

If you feel that you don't get enough sleep, you must have experienced various problems caused by insufficient sleep. In one survey, 38 percent said they fell asleep unconsciously during the day at least once in the past month. Even more alarming, 5% said they dozed off while driving or did fall asleep.

If you don't get enough sleep, it will undoubtedly affect your physical function, your memory, and reaction time. It will undoubtedly affect your driving.

Another study has shown that frequent sleep deprivation can lead to unconsciousness. Nearly a quarter of those who admitted to sleeping less than seven hours had difficulty concentrating during the day, and nearly a fifth had memory problems.

Sleeping less than seven hours can get in the way of daily work, and many things need to be done every day, and you take it for granted.

Although sleep needs vary from person to person, most adults need seven to nine hours to feel refreshed, according to guidelines cited by the Centers for Disease Control and prevention from the National Sleep Foundation.

But in modern society and at this age, it's hard to reach that balance point. Between 1985 and 2009, the proportion of people who slept less than seven hours jumped from 23% to 35%.

Concerning the staggering figure (the proportion of people who sleep less than seven hours has skyrocketed from 23% to 35%), researchers say this is partly due to changes in staff and the emergence of new technologies - such as smartphones and laptops - that allow us to stay in touch at any time.

You also need to know this:

1. Compared with young adults, people over 65 years old tend to sleep more than 7 hours.

2. When sleeping for less than 7 hours, women are more likely to have problems in their daily work than men.

Almost half (48%) of Americans snore.

So, from now on, we need to make sleep the focus of our health. It's not a luxury.

Lack of sleep can affect daily physical function and mortality. If you don't have enough rest before driving, you may have an accident.

People with sleep disorders - including insomnia, sleep apnea, and leg hyperactivity syndrome - are common. If you always feel bad at rest, consider asking a sleep specialist to help you adjust.
