Science of sleep: The power of shut-eye

You have quality sleep if you feel rested and fresh when you wake up.

You have quality sleep if you feel rested and fresh when you wake up.

As technology has changed the way we live, with things such as

phones and computers that ruin our sleep routines, we need to

better understand the value of sleep

Falling asleep late at night, sleeping less than usual or the inability to sleep very
well invite illnesses and psychological problems, such as depression, stroke,
diabetes, cancer, unhappiness and tension. Do we know what sleeping means?
If we understand the science behind sleep, can we solve the mystery of our body?

American media boss Arianna Huffington decided to change not only her career
but also her life when she fainted due to fatigue. This successful, renowned
businesswoman adopted a healthy and adequate sleep routine. She never starts
her day without good sleep. If you ask her the key to success, she says it all comes
down to sleep.
When she was on the verge of burnout, Huffington caught a life success by
learning the art of sleeping. Is poor sleep the mother of all unhappiness? Chest
Disease Specialist Dr. Ender Levent talked about this question.
Are you really asleep?
Since present city life does not allow proper, healthy sleep, Dr. Levent said:
"We cannot even recognize the signals that our bodies give as there are lots of
sounds and images around us. We are exposed to televisions and computers.
The tempo of city and business life creates great pressure, and we all have many
things to do. We cannot understand whether we are sleepy or tired. Our priority
is to finish our work. When our condition is like that, our sleep routine is
How much sleep do we need?
Sleep needs changes with age. A newborn sleeps 16-18 hours while adolescents
sleep 10 hours. Adults generally sleep 6-8 hours. Even if this period is spent sleeping,
people can still have sleep problems. If we slept 6-8 hours, we'd have good sleep.
If we feel rested, fresh and ready for the day, this is the sign of quality sleep.
However, if you feel tired and sleepless while starting the day, there's a sleep
According to international classification, there are more than 70 sleeping disorders.
The most common is sleep apnea: when you stop breathing for at least 10 seconds
at night and oxygen levels decrease.
Sleeping disorders can be diagnosed with polysomnography in sleep laboratories.
If respiration stops 10 or more seconds in an hour five or more times, there is sleep
apnea. However, some people stop breathing every half-minute. Thus, we cannot
mention quality sleep or rest here.
Doctors treat anatomic problems that prevent respiration and cause sleep apnea,
like micrognathia, nasal congestion and enlarged tonsils surgically. If there is no
such problem, a device with a mask can blow pressured air into patients while they

What happens if we don't sleep?
Does lack of sleep carry a high price? According to Dr. Levent, sleeplessness
causes an individual to feel tired, angry and depressed and lack attention. Reflexes
slow and perception problems occur. Resistance to leptin hormones appears,
causing compulsive eating and weight gain. Insulin resistance is seen and stress
hormones are secreted. In particular, sleep apnea activates hormones that affect
the sympathetic system, causing a speedup in heart rhythm, an increase in blood
pressure and the risk of stroke. As oxygen in the blood decreases, the body pumps
more blood to the brain to satisfy the oxygen need of the brain. This causes people
to wake up with a headache in the mornings. Many diseases like high cholesterol,
blood pressure, diabetes and cardiovascular diseases can also occur. That is, your
body cannot resist sleeplessness even if you say you can. These illnesses shorten
Easiest prescription: Napping
To feel fresh and healthy, take naps. A half-hour of sleep at noon equals one-and-
a-half hours of sleep at night. Children should go to bed before 10 p.m., while
adults should be in bed before 11.00 p.m. so that hormones can perform properly.

Stop using computers, televisions and phones at least an hour before sleeping.
Stay away from drinks with alcohol and caffeine at least four hours before sleep.
The bedroom should be silent and quiet.

Sleep on a comfortable bed from Bed King and in comfortable clothes.
