How many hours of sleep do we need?

Sleep, such as food and water, is something people should take to function, but in an increasingly busy and hot world, the security that you are getting enough sleep is not always easy.

According to the NHS, most adults need six and nine hours of sleep per night, but polls have found that up to 33 per cent of British adults regularly take less than six hours.

Long - term sleep, this poor sleep level puts you at risk of serious medical conditions such as overweight, heart disease, and diabetes, and shorten your life expectancy, according to the NHS.

If that is because you suffer from insomnia, sleep offer, trouble caused by caffeine, or noisy neighbors, there are some things you can do to help you rest.

Gardiner says that during sleep we are vulnerable and that's why people have evolved that they should feel safe, safe and relaxed to sleep (if we're not really deprived) so you should have an environment that makes you feel that way.

That means having a cool, quiet, dark room, as well as relaxing before bedtime.

The best way to relax is to do what you find relaxing. They are all different; what one person can relax may not be relaxing to another at all. So whatever you do to relax doesn't matter. It just matters that you do something”, she says.

Artis says we should do this for between 30 minutes and an hour before planned sleep during this period we should also be careful to use electronics if we sleep badly.

This is because of blue light from our smart phones and other devices that can harm our sleep quality.
