After lying down for a long time, my vision went dark.

In modern society, with the emergence of a large number of electronic products, eye problems have become a normal thing, but we encounter some different problems in daily life, such as blacking out in front of the eyes after lying down for a long time. Many people will feel inexplicably fear when they encounter something that cannot be explained, but blacking out in front of the eyes after lying down for a long time has no direct connection with the eyes themselves. The following is a specific explanation of the reasons why the eyes become black after lying down for a long time. I hope it can help you.

This is temporary brain hypoxia... Generally speaking, this is not a problem. Just some anemia.

When you stand up after waking up, sitting or squatting for a long time, you may suddenly feel dizzy. In mild cases, you may only feel dizzy for a few seconds before recovering, but in severe cases, you may become severely dizzy and lose consciousness, causing you to fall and potentially cause brain or body injuries!

This condition is medically known as "postural hypotension." Why is it that some people can stand up easily without any difficulty, while others may suffer physical discomfort or even injury? In fact, this is related to your physical health. As long as your body circulation is good, this situation will not easily occur. As for those who already have postural hypotension, there is no need to be too nervous. As long as they develop the habit of not changing positions immediately, they can avoid discomfort or injury.

Understanding postural hypotension

Causes of postural hypotension

When we want to change from lying, sitting or squatting to standing up, the posture looks simple, but it requires the coordination and cooperation of various organs of the body, including the heart, blood vessels, nerves, etc., to accomplish the task of standing up smoothly.

When the body wants to stand up, the heart must deliver enough blood through the blood vessels to the brain, which is located at the highest point. At this time, the blood vessels must be coordinated by the nervous system to appropriately reduce their diameter so that the blood can be delivered higher and farther. However, if these organs react too slowly or are unable to perform this function, the brain will experience temporary hypoxia, causing dizziness or fainting, which is called "postural hypotension."

Good target

Although postural hypotension is not a highly contagious disease like the common cold, according to clinical observations by doctors, more than half of the people in the country have experienced postural hypotension, with women being the majority. If divided by age, the elderly have more than the young, and the others are pregnant women.

From this we can see that this is related to the human body's nerve response and blood circulation. Generally speaking, men have better blood circulation than women; and young people have better blood circulation than old people; as for pregnant women, most of them are in the middle and late stages of pregnancy, because the fetus grows bigger, which makes the blood circulation in the lower body poor.

What to do when you feel dizzy?

When dizziness caused by postural hypotension occurs again, it is recommended that you find a chair to sit down as soon as possible, or lie down on the bed at home to increase blood circulation in the brain, reduce the degree of dizziness, and avoid fainting and injury.

How to prevent postural hypotension?

1. "Activate your muscles and bones" before changing postures

Whether you are getting up before waking up, or standing up after sitting or squatting for a long time, you should warm up your muscles and bones before changing your posture to avoid causing postural hypotension. For example: straighten your right foot and then bend it, do it alternately five times, then switch to the left foot; then stretch both feet together, and then slowly sit up; stay for five to ten seconds and then stand up. After standing up, do not walk immediately. Make sure you do not feel dizzy before you start walking.

2. Exercise more and get enough sleep

Since the occurrence of postural hypotension is related to poor blood circulation, simply moving more often can not only keep your muscles and bones flexible, but also prevent your nerves from aging. For example: swimming, jogging, and gymnastics are all good exercises. In addition, going to bed early and getting up early is also an important way to keep your body healthy and your metabolism normal. As long as you pay attention to these two points, I believe that not only will postural hypotension rarely visit you, but your body will also become more resistant.

Reminder

Postural hypotension is not

disease, but from time to time he would make people feel sad and "faint"! Especially in an era when white-collar workers make up the majority, more and more people "sit" from work to get off work every day, go home after get off work and continue to "sit" until bedtime, and then "lie down" and sleep until dawn!

This lack of exercise in life makes many young people easily tired and prone to diseases that should occur in old age, postural hypotension being one of them. So, on weekends, I suggest you turn off the TV, shut down your computer, change into some comfortable clothes, and go out for a walk with your whole family! This is not only good for health, but also very helpful for family and parent-child interactions!
