What are the symptoms of lack of sleep? The harm is so great

Life lies in movement, but getting enough sleep is also essential. If you lack sleep for a long time, it will cause immeasurable harm to the human body. It will also affect brain thinking, reduce work efficiency, accelerate aging, and cause various diseases. If teenagers do not get enough sleep, it will affect their normal development.

1. Affect brain thinking and reduce work efficiency

I believe everyone has experienced this: the next day after staying up late, you often feel dizzy, unable to concentrate, and even have a headache at work or in class. Staying up late and insomnia for a long time also cause invisible damage to memory. Expert experiments have proved that in order for the human brain to think clearly and react quickly, it must have sufficient sleep. If people do not get enough sleep for a long time, they will become anxious and worried, and the brain will not get enough rest, which will affect the brain's creative thinking and ability to handle things. As a result, work efficiency is greatly reduced.

2. Lack of sleep in adolescents affects normal development

Modern research shows that the growth and development of adolescents is related to the secretion of growth hormone in addition to factors such as genetics, nutrition, and exercise. Because the secretion of growth hormone is closely related to sleep, that is, there is a large secretion peak after a person falls asleep, followed by several small secretion peaks, while in the non-sleeping state, the secretion of growth hormone decreases. Therefore, if teenagers want to develop well and grow taller, they must get enough sleep.

Bad living habits such as stress, picky eating, and lack of sleep can also increase melanin. 10 pm and 6 am are the best times for metabolism, so people with unstable sleep schedules will have poor skin metabolism rate and will produce melanin.

3. Lack of sleep accelerates aging

Lack of sleep leads to dark circles, eye bags, and dry skin. Night is the body's physiological rest time. If you don't rest when you should, you will become overly tired, which will cause poor blood circulation around the eyes, causing dark circles, eye bags, or bloodshot whites of the eyes. 11pm to 3am is the beauty time, which is the time when the body's meridians run to the gallbladder and liver. If these two organs do not get enough rest, it will be reflected in the skin, causing problems such as roughness, yellowish complexion, dark spots, and acne.

4. Lack of sleep leads to various diseases

Regular lack of sleep will make people feel anxious and worried, and reduce immunity, which will lead to various diseases such as neurasthenia, colds, gastrointestinal diseases, etc. In addition, expert research shows that insufficient or irregular sleep not only makes people have puffy eyes, become addicted to coffee, and nap during afternoon meetings, but also increases the risk of a variety of major diseases, including cancer, heart disease, diabetes, and obesity.
