Several major organs of the body also need to "sleep", are you still staying up late?

Is staying up late harmful? Yes! The impact is huge! You must have seen many examples of staying up late harming your body or making you sick. You also feel your brain is in a fuzzy state after staying up late. Why? That’s because some organs can only get “rest” during sleep, but you deprive them of the right to rest! It would be strange if I wasn't sick~

brain

Sleep mode is turned on

When the brain is working, it produces a large amount of metabolic waste due to the high energy consumption of brain cells. To clean them up, a special "clean water" is needed - cerebrospinal fluid.

According to research, as the brain is about to fall asleep, brain cells become smaller and create gaps through which cerebrospinal fluid flows and carries away waste. That is, the brain doesn't switch to "cleaning mode" until it's time to go to sleep.

However, if you have been staying up late, it means that the reason you feel sleepy after work is most likely because too much metabolic waste has accumulated in your brain. Too much metabolic waste will make us slow to react, depressed or irritable, and reduce our work efficiency. When it accumulates to a certain level, it will even kill brain cells and cause damage to the brain. In severe cases, it may also lead to diseases such as vascular dementia.

Staying up late hurts your brain - be careful to become stupid

Currently, there is no drug that can achieve the same effect as sleep in clearing brain waste without causing side effects to the human body, so sleeping is really the best way to protect your brain!

heart

Heart rate slows during sleep

There is a total limit to the number of times your heart beats. Generally speaking, more than 95% of normal adults have a heart rate of 60-100 beats per minute, and the heart beats approximately 2.5 billion to 3 billion times in their lifetime. If the heart rate is too fast, the total number of heart beats will be quickly consumed, which will naturally shorten your life.

When people sleep, their heart rate drops significantly, 10-30 beats per minute less than when they are awake. Compared with the hard work during the day, sleep at night can be said to be a "resting time" for the heart.

Staying up late and feeling sad - beware of sudden death

Staying up late for a long time greatly shortens the heart's "rest time".

At the same time, staying up late puts people in a state of stress, constantly secreting hormones such as adrenaline, which will cause abnormal contraction of blood vessels; long-term lack of sleep can easily make people feel nervous and anxious, and is more likely to induce or aggravate high blood pressure. Staying up late will invisibly add to the burden on the heart. For people who already have heart disease, it can easily lead to myocardial infarction.

stomach

Slower movements during sleep

After falling asleep, gastrointestinal motility slows down and the stomach also "rests". The life span of gastric mucosal epithelial cells is very short, and they need to be regenerated every 2-3 days. This regeneration and repair process usually takes place at night when the gastrointestinal tract is resting.

Staying up late hurts your stomach and intestines - be careful of ulcers

When you stay up late, your stomach and intestines cannot get rest, and your gastric mucosal cells cannot be renewed. In addition, many people are accustomed to eating midnight snacks, which stay in the stomach for a long time, causing a large amount of gastric juice to be secreted, causing irritation to the gastric mucosa, which can easily lead to gastric mucosal erosion and ulcers over time. If the gastrointestinal tract does not get "rest", problems such as functional disorders and constipation will follow.

muscle

Sleep recovery function

During sleep, muscles throughout the body are in a state of relaxation, and growth hormone is released into the blood, restoring and rebuilding body tissues and promoting muscle recovery and regeneration.

Staying up late hurts your muscles - weakened ability

Muscles are not only necessary for everyone's life, but also loved by fitness enthusiasts. However, if you are sleep-deprived and still doing muscle training, the maximum weight you can bear during training will be greatly reduced, which is not good for muscle expansion and growth.

kidney

Filtering will be slower

When you sleep, your kidneys are also "resting", filtering will be slower, and you will produce less urine than during the day.

Staying up late hurts your kidneys - be careful of nephritis

Long-term lack of sleep can harm the body's immune function, and immune dysfunction can manifest itself in the kidneys and cause nephritis.

Give your organs a rest and remember these 5 rules

1. 23:00 is the limit for sleeping in late

Zishi (23:00-01:00) is the time when the Foot Shaoyang Gallbladder Meridian is on duty. It is the time for bile metabolism and bone marrow hematopoiesis. This is the beginning of the body's rest and repair, and you should go to sleep. Those who fall asleep before midnight will have a clear mind and rosy complexion the next day.

2. Don’t think before going to bed

“Let your heart sleep first, then your eyes.” If you want to fall asleep before 11pm, it is important to go to bed early to prepare your emotions, giving your mind some time to calm down. Don't toss and turn in bed, as this will drain your energy and make it harder to fall asleep.

3. Keep your bed away from electronic devices

All electronics must be removed! Televisions, game consoles, computers, phones, and other gadgets are all rest-destroying items. Don't allow them in your bedroom and don't use them shortly before bedtime.

4. Eat less 2 hours before bedtime

Generally speaking, after dinner, the stomach needs 3 hours to digest the food and eventually empty it. If you eat dinner too late and go to bed while the stomach is still working hard to digest food, your sleep quality will often be poor. If you cannot eat dinner on time due to overtime or other reasons, you should try to ensure that there is a 2-hour interval between dinner and sleep.

5. Avoid strenuous exercise 2 hours before bedtime

When it is time to go to bed, you should avoid strenuous exercise, excessive sweating, excited limbs before going to bed, and high body temperature, as these will reduce the quality of sleep. Generally, strenuous exercise should be stopped within two hours before bedtime.
