'Lack of sleep' is just our imagination

Most, if not even society, complain that they are always lacking in sleep. But that is only a fantasy, one of the world's leading sleep researchers, English professor Jim Horne, said.

Thanks to the frequent assertions that the ancient ancestors slept more than we do today, it's easy to understand why people think that they lack constant sleep.

"The reality is, most of us are getting more sleep than we need - we just fool ourselves and we are suffering from chronic insomnia, " Jim Horne said.

In 1894, the British Medical Journal ran a headline warning that modern life was " rushing and bustling " leading to widespread insomnia. " But I think it's never been better than today ," he said.

Unlike a typical 150-year-old worker, people who work 14 hours a day, 6 days a week and return home on a bed full of fleas and crowded with people, most of us today much more comfortable sleeping.

There have been several large-scale studies over the past 40 years that how much time we spend in bed. The findings show that on average healthy adults sleep about 7 to 7.5 hours per night.

The " reality " that people often repeat that our father slept more, about 9 hours, was a paranoia, and stemmed from a study in California in 1913, that children aged 8 to 17 need 9 hours of sleep a day.

So you should know that even today, that number is true for this age - parents with children in adolescence will attest to it! But adults do not need so much sleep. Some people only sleep 5 hours a night, while others need 7 hours.

The only part of your body that will be affected by lack of sleep - and must be a few days without sleep - is the brain. Tests have shown that there is no physical difference in muscle or muscle bundles when you sleep enough compared to when you just lie and stay awake.

But the brain is another problem. It needs sleep. Although it only accounts for 2% of your weight, it uses up to 20% of the energy you consume.

And although most of us sleep well enough, an entire industry has emerged to help us overcome "problems with sleep". I warned that it could be a loss of money.

Experts also give some advice for you to get real sleep:

Room temperature : Ideally 18 degrees Celsius, make sure the body temperature is low enough to fall asleep. If above 24 degrees Celsius, the brain will not send signals to trigger sleep. If the room is too cold, below 12 ° C, the body will struggle to maintain body temperature and make it difficult for you to sleep.

Blanket : There should be separate blankets for winter and blankets for summer

Ventilation : Always open a window, even in winter. Fresh air will help you sleep deeply.

Bed : Don't be stingy when buying a bed, because that's what you'll spend 25 years in your life. A normal person will secrete about 0.3 liters of sweat in the night and change position 40-60 times. Choose a thick, firm mattress. Cushions should change after 12 years.

Bed sheets : It is best to use cotton and linen to absorb sweat.

Lavender oil : It is recommended to anoint a little lavender oil on the pillow and in the air. It will increase sleep quality by 20%.

Pajamas : Spacious and made of natural fibers.

Alarm bell : Turn it off or it is best not to use it. Alarms make you nervous.

Curtains : The thicker the better. Ideally, the room should be completely dark until 4 am for optimal sleep.

Television : Do not put in the bedroom.

Spouse: If your spouse often turns up or snores loudly, it's best to sleep on your own bed. " People with deep sleep often have a high divorce rate and sleeping alone can improve rather than destroying sex life ," said Professor Neil Stanley.
