Sleep timing is the most dangerous to health

Sleep timing is the most dangerous to health

Sleep timing is a key factor affecting physical and mental health

yet many continue to ignore it in the midst of accelerated lifestyles.

In this regard :

Dr.Saurab Sethi, a gastroenterologist residing in California, highlights the effects of

staying up late beyond midnight, warning of its negative repercussions on

body functions and the quality of daily life.

He explained that

late sleep is associated with weight gain, mood dysfunctions, high stress

and poor mental performance, and may increase the risk of heart disease.

Sethi said that sleeping after midnight frequently disturbs the physical and

psychological balance and impairs the body’s vital functions, especially when

sleeping less than 7 to 9 hours a day, which is the period recommended by doctors.

Staying up late leads to :

a hormonal disturbance in hunger and satiety :

which prompts a person to eat unhealthy meals. A study published in the journal

JAMA showed that those who sleep after midnight have a 20% increased risk of

weight gain compared to those who sleep between eight and ten in the evening.

A study :

conducted by Stanford University School of

Medicine confirmed that sleeping after one in the morning is associated with an

increased risk of depression and anxiety disorders, even in those 

who do not previously suffer from these conditions.

Staying up late also affects the balance of hormones, which leads to increased

levels of cortisol and stress hormones, and makes the person more irritable.

Early sleep enhances memory and cognitive functions

while staying up late leads to decreased mental and cognitive performance.

Sethi noted that

sleeping early may also help prevent heart disease. A study conducted

by the British Heart Foundation found that sleeping between ten

and eleven in the evening is associated with a lower risk of cardiovascular disease

results supported by research published in the European Journal of Cardiology.

The doctor concluded

his advice by saying :

"Make sure to sleep before midnight and adhere to a regular sleep routine that

ensures your body’s balance, improves mood

and protects you from serious diseases in the long term.".

Secrets of good healthy sleep

An adult's sleep period goes through different cycles and frequent short

awakenings during the night. Sleep cycles last approximately 90 minutes per cycle.

Typically :

we start with light sleep, before moving on to deeper sleep stages, then rapid eye

movement (REM) sleep, the sleep stage often associated with vivid dreams

What does it mean to get "good" sleep?

Adults usually need about 7 to 9 hours of sleep each night

but good sleep is not only about the number of hours, but also about quality.

For most people

good sleep means being able to fall asleep soon after going to bed

(within about 30 minutes), sleeping without waking up for long periods

waking up feeling rested and ready for the day.

But if you :

notice you're feeling physically tired, need to nap regularly and still don't

feel refreshed, it may be worth reaching out to your GP

as there are a range of possible causes.
