Recently, American experts have studied that waking up early is harmful to health, and citizens have expressed their approval.After entering winter, most office workers and students probably want to sleep in late?Now that the argument that waking up early is harmful to health has emerged, can we openly sleep in late?

Experts are constantly in a loop of drawing conclusions and overturning conclusions, of course, the American study that early death is harmful to health has no relation to us.Americans' work and sleep schedules are different from ours, many Americans sleep at 10 pm and wake up at 5 am to exercise.Breakfast|The premise of waking up early is to sleep early, otherwise, insufficient sleep is easy to die.Therefore, this is not a reason for us to be late!

The study says that waking up early is harmful to health.

Researchers at the University of Texas say that every time you wake up early, it can cause irreparable damage to your health, especially for mental health.To prove this theory, experts conducted an experiment involving hundreds of volunteers.The study results show that people often wake up early due to work, which makes them sensitive and irritable, and they feel tired all day.

Best time to wake up

7:21 am is the best time to wake up.

These results were announced at the "Fifth International Conference on Sleep Research and Sleep Medicine" which ended on September 7.The study was conducted jointly by several universities in Tokyo, Japan.After investigating 3017 healthy adults aged 23-90, the researchers found that people who wake up earlier are more likely to suffer from highbloodpressure, stroke, and other cardiovascular diseases.The researchers also said that among those who wake up early, most are elderly people, and they are already at high risk of suffering from cardiovascular diseases.Therefore, the researchers also said that this claim needs further research, but it does provide some reminders.So, what time is the healthiest to wake up?Researchers at the University of Westminster in the UK found that waking up after 7:21 am is best, because if you wake up between 5:22 and 7:21, the substances in your blood that can cause heart disease may increase.Professor Jim Horn, a professor at the Sleep Research Center at the University of Laffer, suggests: "As soon as you wake up, turn on the lights, which can help adjust your biological clock and make you more awake."In addition, when you wake up, try not to be too abrupt, but lie in bed and move your limbs and head for 5 minutes, otherwise it will cause sudden changes in blood pressure.

However, Professor Hong Zhao Guang, the chief health education expert in China, told reporters of "Life Times" that the best time to wake up is not a fixed value."The key to health is to follow nature, rise with the sun and set with the sun.When the sun rises every day, the human biological clock will issue a command, and the sympathetic nerves will be excited, which is the time to wake up."Therefore, with the different running patterns of the sun in the four seasons, people's waking times should also change. In spring and summer, you should go to bed late and wake up early. In autumn, you should go to bed early and wake up early. In winter, you should go to bed early and wake up late.

Sleeping 1 hour less, death rate increases by 9%

Professor Hong Zhao Guang also emphasized that no matter what time you wake up, it is most important to get enough sleep."During the day, the proportion of time that people are awake and asleep should be 2:1, which means that 8 hours of sleep is the best.If you sleep less than 7 hours on average, the death rate will increase by 9%.”

For teenagers, primary school students should get 10 hours of sleep, and middle school students should get 9 hours, otherwise it will affect the physical and mental development of underage children, leading to decreased attention, memory, and self-control, and may also cause immune and endocrine system disorders, leading to obesity.

Old people should exercise in the evening

"I usually wake up before 6 am, and I lie in bed and do nothing, what else can I do?"Many elderly people have this question.However, Professor Hong Zhao Guang said that elderly people over 80, with high blood pressure and heart problems, must get enough sleep and wake up later."When you wake up early, the sympathetic nerves are already excited, and the heart is already under heavy load, so waking up early for exercise is even more harmful to the body.Therefore, it is best for elderly people to wait until their physical condition is good in the evening to exercise.”

For elderly people who are used to waking up early, Professor Hong Zhao Guang suggests: "It is best not to sleep during the day;Increase exercise, because exercise can consume energy, and it has a stabilizing effect.

What are the disadvantages of going to bed early

Going to bed early generally means resting around 10 pm, because by 11 pm, the various organs in the human body begin to repair and detoxify. For example, the liver starts to detoxify at 11 pm. If you go to bed late, such as 1:00 or 2:00 am, and do this for a long time, your liver will be prone to problems. In addition, all the organs from the inside out need to rest.

If you extend their work time, you will know the consequences after a long time. Look at those people who die from cancer around 40, basically are young people who have had bad living habits, and have been like this for many years. Therefore, there will be the result. If you go to bed late, your overall condition will be much worse than those who go to bed early.

Let's talk about waking up early again, because the human body has a fixed biological cycle and rhythm, such as the brain, after a night's rest, it will start to recover its movement at a fixed time. When you force it to be in a state of sleep at this time, it will violate the rhythm, and you will find that the more you sleep, the more you want to sleep, and after waking up, your spirit will not be very good, and you will feel tired all over.

If you go to bed before 11 pm and wake up at 7 am, you can rest for 15-30 minutes at noon. If you do this for a long time, it will bring you health. Of course, diet and exercise are also very important.

Many teenagers think that their energy is very abundant, and they often stay up late, which has become a habit. At this time, our bodies are constantly being overdrafted, leading to physical weakness, dizziness, and inattention. We must eliminate the bad habit of staying up late, and protect our physical health.
