Sun Yat-sen University research found that staying up late to watch the ball and catching up on sleep during the day increased the risk of fatty liver

Sleep is a healing process in the human body that restores the spirit and relieves fatigue
.
About one-third of a person's life is spent in sleep, good sleep is one of the three internationally recognized health standards, and too short sleep or poor sleep can affect health
.

In today's society, staying up late has become the new normal for many young people
.
Staying up late often will bring great harm to the body, such as staying up late will cause metabolic disorders, biological clock disorders, etc.
, and more seriously, staying up late for a long time will also cause sudden death
.

Metabolism-related fatty liver disease (MAFLD) is the leading chronic liver disease worldwide and can lead to liver failure and even death
.
In addition, due to the rapid increase in unhealthy lifestyles, the prevalence has soared rapidly, and the prevalence of metabolism-related fatty liver disease in China has increased from 18% to 29%
in the past decade.

Recently, Professor Xia Min and Associate Professor Liu Yan of Sun Yat-sen University and Zhu Wei of Guangzhou CDC published an article entitled "Sleep Factors in Relation to Metabolic Dysfunction-Associated Fatty Liver Disease in Middle-Aged and Aged Chinese Get Access in the journal "JCEM" of Clinical Endocrinology and Metabolism Arrow" research paper
.

The study showed that staying up late, napping, and snoring were all associated with a higher risk of metabolism-related fatty liver disease, with poor sleep at night and people who took long naps during the day having the highest
risk of fatty liver.
In contrast, high sleep quality was associated with
a reduced risk of fatty liver.

In the study, researchers analyzed self-reported sleep data from 5,011 Chinese adults, and 1,423 cases were diagnosed with fatty liver
.
The time to fall asleep is divided into 3 groups: before 10 pm, between 10-11 pm, and after
11 pm.
Nighttime sleep was divided into 3 groups: short (< 7 hours), normal (7-8 hours), and long (> 8 hours).

Assess the degree of
insomnia, snoring, and excessive daytime sleepiness based on the number of episodes.
The length of the nap is divided into 0-30 minutes and more than 30 minutes
per day.

Low-risk sleep factors were defined as: early bedtime (falling asleep before 10 p.
m.
, falling asleep at 10-11 p.
m.
), 7-8 hours of nighttime sleep, rarely insomnia, rarely snoring, rarely daytime sleepiness, and napping for less than 30 minutes, and if participants were judged to be low-risk sleep, they would receive a healthy sleep score of 1, otherwise 0
.

The study found that staying up late, snoring, and taking long naps during the day were significantly associated with an increase in fatty liver disease, with an increased risk of 37%, 59%, and 17%,
respectively.

Correlation between different sleep patterns and MAFLD risk

In addition, participants who slept poorly at night and took longer naps had the highest risk of fatty liver disease, with a 138%
increased risk.

Effects of nocturnal sleep patterns and napping on MAFLD risk

The study also found that the risk of fatty liver gradually decreased
as healthy sleep scores increased.
Having any of the 6 healthy sleep behaviors was associated with a 16% lower risk, and modest improvements in sleep quality were associated with
a 29% lower risk of fatty liver disease.

Healthy sleep scores are increased and the risk of MAFLD is reduced

Further analysis showed that poor sleep quality was more harmful to fatty liver in sedentary and obese people, but obesity accounted for only 20.
8%
of the overall impact of sleep quality on the risk of fatty liver.

In conclusion, the study highlights that good sleep must be a top priority
in everyone's life.
Unhealthy sleep factors such as staying up late and taking long naps were associated with an increased risk of fatty liver, and high sleep quality was associated with
a reduced risk of fatty liver.
