The harm of long sleep time

After a busy day or during holidays, many people like to have a good sleep, and the longer they sleep, the better they feel. In fact, daily sleep is very important. If you sleep too long, it will often cause certain harm. So, what are the dangers of sleeping for a long time? Let’s take a look at the dangers of sleeping for a long time.

Sleeping too long can cause decreased intelligence

In life, people often complain that they sleep too little, which causes them to feel dizzy and weak all over. Therefore, most people believe that sleep is the way to eliminate fatigue, and the more sleep you get, the better spirits you will feel. In fact, this idea is completely wrong.

Experts from the China Sleep Association pointed out that sleeping too long, like not getting enough sleep, can lead to mental fatigue, physical tiredness and a decreased metabolic rate. Because after sleeping too long, the human heart beat will slow down, the metabolic rate will also drop very low, and the muscle tissue will relax. Over time, people will become lazy, weak, and even their intelligence will decline. Therefore, the idea of ​​increasing sleep time to gain health is not only incorrect, but also counterproductive and shortens life.

Sleeping more than 8 hours a day is more likely to cause diabetes

In addition to shortening your life, sleeping too much or too little can increase the risk of various diseases. According to a study, sleeping too long or too short may induce diabetes.

This research survey report was based on a follow-up survey on the sleep habits of more than 1,100 middle-aged and elderly men, aiming to find out the relationship between sleep time and diabetes. None of the participants had diabetes at the start of the study. After taking into account factors such as age, blood pressure, smoking history and obesity level, the researchers found that people who sleep 7-8 hours a night are the healthiest. However, if you sleep less than 6 hours a night, your risk of diabetes will increase by about 2 times; if you sleep more than 8 hours, your risk of diabetes will increase by more than 3 times.

The above is an introduction to the dangers of long sleep time. I hope it will help you understand. I believe that many people may think that long-term sleep is good for the body, and they certainly would not think that it would cause harm in this regard. Therefore, in daily life, we should not only pay attention to the time of sleep, the key is the quality of sleep, which can make us healthier.
