If someone tells you that they don’t get enough sleep and are always listless, you may touch his head and comfort him.
But if someone tells you that he has slept for a long time and is still uncomfortable, you will definitely say to him:
[How many people still don’t sleep enough! How long have you been sleeping? ]
In fact, sleeping too long and too little is an irregular sleep for the body. It is inevitable that all kinds of discomfort will occur, including all kinds of tiredness, all kinds of headache and all kinds of unconsciousness.
So, the first question comes… … …
How long does it take to sleep?
For most adults, it is good to sleep 7-9 hours a day.
Of course, a few people with unique talents or different genes can only sleep for 6 hours a day and can still be resurrected with blood the next day. There are also a few adults who need to sleep more than 9 hours a day.
However, the proportion of these two kinds of people is lower than we thought, so if you sleep more than 9 hours, you may belong to the “sleep long” camp.
Then, the second question comes… … …
Why do you feel tired after sleeping too long?
You may have had such experiences. You worked hard for a week and wanted to get a nap on weekends. As a result, you slept directly until noon or afternoon the next day. When you woke up, not only your mind was a little faint, your eyes could not be opened, your body felt very tired, and you even had a headache…
Help, why is this happening? Isn’t sleeping to relieve fatigue?
In fact, one of the important reasons why sleeping too much can make people listless is that this long sleep time misleads the biological clock.
Generally speaking, the brain’s biological clock will send signals to the whole body, making all cells in the body at the same rhythm. If you sleep too much on weekends, it is equivalent to getting rid of the original biological clock and starting to send signals to the body of another rhythm.
This is similar to jet lag, which belongs to irregular work and rest, thus affecting sleep quality and naturally feeling tired when waking up.
If you don’t feel tired after sleeping too long, but feel headache, that is the third problem.
Why do you have a headache when you sleep too long?
There should be many people who sleep too much and have headaches.
In fact, this is mainly because too much sleep disturbs the balance of neurotransmitters such as serotonin in the brain, and people will have headaches.
At the same time, too much sleep may also lead to inflammation of the middle cerebral artery and migraine.
This is not the most terrible, the fourth question is the most frightening.
Will sleeping too long harm your health?
The fact is, it will.
A recent study based on millions of people found that sleeping too much or too little every day has a greater risk of cardiovascular diseases.
Compared with normal sleep, long sleepers have a 33% increased risk of developing or dying of coronary artery disease and stroke.
For most people, sleeping too much is not only more likely to suffer from diabetes, cardiovascular diseases and obesity than normal people, but also may have memory problems, which may even be an early manifestation of senile dementia.
I suddenly felt that modern science was going to deprive [sleep], the last thing that made people happy…
Relax, relax, it doesn’t matter if you don’t want to sleep too long, after all, there is another thing called [alarm clock] in the world.
If the alarm clock still doesn’t wake you up, then you have to use the last trick and whisper in the sleeping person’s ear:
[I’ve come to look through your cell phone! ]
If you find that your sleeping time is out of your control, you’d better ask a doctor for help and let the doctor find out the real reason before we can sleep well, wouldn’t you?
