Can brain hypoxia cause damage in just 5 seconds?

Although the weight of the brain only accounts for 2% of the body, it consumes the most oxygen. Research has confirmed that 15% of the heart's blood supply is supplied to the brain to maintain energy and oxygen consumption. It can be said that the brain is a very afraid organ of hypoxia.

If the oxygen supply is insufficient, even in just 5 seconds, the brain will undergo changes:

Firstly, there is a feeling of trance and dizziness;

2. If there is ischemia and hypoxia for 15 seconds, it may cause syncope;

If there is ischemia and hypoxia for 5 minutes, irreversible damage to the brain will occur, and ischemic changes can be seen in the brain through magnetic resonance imaging and CT examination.

Oxygen is so important to the brain, but many people may be chronically hypoxic without realizing it!

Generally speaking, the early typical symptoms of chronic hypoxia in the brain are poor sleep and decreased memory. Afterwards, there may be dizziness, headache, decreased memory, inattention, insomnia, and other issues. If you encounter the above problems and cannot find a clear cause, you need to be vigilant.

People who don't like opening windows are more likely to experience brain atrophy?

I prefer to stay indoors but do not like to open windows for ventilation, which can reduce the indoor oxygen concentration and easily lead to cerebral hypoxia.

In a certain program, a test was conducted where the oxygen content in one's own bedroom was 19.6%, while the oxygen content in one's parents' room was 19.5% and 19.4%, respectively, with the doors and windows closed. The oxygen concentration in the general atmosphere was about 21%.

Long term exposure to such closed rooms can inevitably lead to hypoxia, headaches, emotional instability, insomnia, and other symptoms, which may also lead to brain atrophy over time. If the bedroom is crowded, not ventilated, and has a small space, the situation will be more severe.

These 5 common habits can actually be very frustrating

1. Eating too fat leads to rapid brain aging

Obesity is the root cause of all kinds of chronic diseases. A study published in the Journal of Aging Neurobiology suggests that the brains of overweight individuals are 10 years older than those of thin individuals of the same age, especially after middle age, where the brains of obese individuals age faster. Comparative studies have found that the white matter of the brain in overweight individuals is much lower than that in lean individuals. White matter in the brain is the white neural tissue that connects different regions of the brain and promotes information exchange.

2. Sleeping with your head covered, hypoxia can damage your brain

Covering your head while sleeping can increase the concentration of carbon dioxide in the bedding and decrease the concentration of oxygen. After a night, due to poor breathing and insufficient oxygen replenishment in the brain, it is easy to cause low oxygen content in the cerebral blood vessels and damage the brain. So often after waking up, I feel dizzy and dizzy, and my energy is not focused.

3. Lack of communication and reticence

We have a language specific lobe in our brain, and frequent speech can also promote brain development and exercise brain function. People who remain silent and unsmiling all day will experience a decline in their functions and the brain will begin to age. Many patients with Alzheimer's disease (Alzheimer's disease) experience early symptoms of being silent.

4. Frequent staying up late and insufficient sleep

The main way for the brain to eliminate fatigue is through sleep. Long term lack of sleep or poor quality will only accelerate the decline of brain cells, and smart people will also become confused. Therefore, people who often stay up late and lack sleep often experience brain degeneration earlier.

5. Disliking to think and read

Many people nowadays dislike reading and thinking. As the saying goes, "If the brain is not used, it will rust." The best way to prevent brain aging is to think more. If the mind is not thinking about things yet, the brain's functions such as reaction, mobilization, and organization will all decrease. The brain, like the body, follows the principle of "using in, discarding out". If you don't use your brain or read, your brain will become dull.

How to replenish oxygen to the brain?

1. Open windows frequently for ventilation

Opening windows, as a traditional and effective ventilation method, is very important for maintaining the cleanliness and freshness of indoor air. Long periods of lack of ventilation can lead to insufficient indoor oxygen. Prolonged exposure to such an environment can cause dizziness, headaches, elevated blood pressure, and even other diseases due to hypoxia.

Maintaining appropriate window ventilation can increase fresh air, reduce carbon dioxide, reduce total bacterial count, prevent and control viruses and bacteria, and also bring negative ions that are beneficial to the body into the room, while sending away excessive positive ions that are harmful to the body.

The correct window ventilation method should be maintained 2-3 times a day for 30 minutes each time, which can effectively improve indoor air quality. Convective ventilation should be chosen as much as possible. Meanwhile, for people living on low floors, in addition to natural ventilation, forced air supply or exhaust can also be chosen.

2. Appropriate supplementation of methionine and omega-3 fatty acids

Methionine helps to improve the speed at which the brain transmits and receives information, helping to alleviate brain stress; Omega-3 fatty acids can supplement nutrients to the brain and help the growth of brain nerve cells.

After the combination of the two, a new lipoprotein compound is produced, which can control the absorption and release of oxygen and maintain the body's oxygen content at a certain level.

Sesame seeds, sunflower seeds, dairy products, yeast, seaweed, leafy vegetables, etc. are rich in methionine; Flaxseed, kiwi seed, deep-sea fish, nuts, etc. are rich in omega - 3 fatty acids, which can be eaten appropriately in daily life.

3. Regular aerobic exercise

Aerobic exercise refers to physical exercise conducted by the human body with sufficient oxygen supply, which can effectively promote blood circulation, enhance cardiovascular function, and increase body oxygen content.

It is recommended to engage in aerobic exercise for at least 30 minutes 3-5 times a week, such as brisk walking, jogging, swimming, skipping rope, cycling, Tai Chi, etc.

How to delay brain aging?

1. Eat some brain building food

Eggs

Eggs are rich in lecithin, which is the most important basic structural substance in brain cells and can provide choline, which is closely related to brain health. Lack of lecithin can lead to a decrease in memory and affect cognitive function.

The most recommended way to eat is boiled eggs or egg custard, and fried eggs with less oil are also acceptable. Fried eggs are not recommended because they not only destroy more nutrients but also have higher calories. The oil absorption rate of fried eggs is as high as 43%, which is not conducive to weight control and increases the risk of chronic diseases.

Seafood

Seafood is rich in DHA, which belongs to n-3 series of unsaturated fat acids. As an important part of the brain, DHA is known as "brain gold". It is not only beneficial to the health of the nervous system, but also has an anti-inflammatory effect. Eating fish is a direct and effective way to obtain DHA, and some studies have shown that people who regularly eat fish have a lower risk of developing Alzheimer's disease.

Common seafood rich in DHA include bluefin, salmon, cod, bass, hairtail, yellow croaker, grouper, etc. Among them, 60 grams of salmon can provide more than 500 milligrams of DHA, and 50 grams of bluefin can provide more than 700 milligrams of DHA, all of which are very good choices.

Green leafy vegetable

Green leafy vegetables are generally rich in vitamin E, folic acid, flavonoids, and carotenoids, which have a delaying effect on brain aging.

Common green leafy vegetables such as amaranth, milk cabbage, chrysanthemum, rapeseed, Chinese cabbage, water spinach, spinach, chives, celery, oil lettuce, coriander, etc. are all recommended. It should be noted that vegetables with high oxalic acid such as spinach, amaranth, and water spinach need to be blanched before consumption to avoid affecting the absorption and utilization of other nutrients. It is recommended to eat 300-500 grams of vegetables every day, with green leafy vegetables accounting for half of the amount.

2. Keep learning and don't let the brain stop thinking

Research has shown that the process of learning new skills is actually a continuous process of reshaping brain function and structure. Therefore, in theory, as long as we don't stop using our brains, thinking, and learning, we can effectively delay brain aging.

3. Maintain enthusiasm for life

When a person is doing something they are interested in, their brain will be in an active state, especially in activities such as playing chess, dancing, playing musical instruments, exercising, knitting, doing handicrafts, raising flowers and plants, writing articles, etc., which require brain exercise. Even taking a walk around the community or chatting with relatives and friends is better than staying at home and not interacting with people all day. In short, it is important to maintain a passion for life and not let the brain idle for a long time.

4. Maintain a nap habit

In 2021, a study published online by Professor Sun Lin from Shanghai Jiao Tong University and Professor Han Cai from the Fourth People's Hospital of Wuhu City, Anhui Province, in the British Medical Journal sub journal "General Psychiatry", showed that nap time can effectively prevent Alzheimer's disease, and regular nap time can also improve thinking agility.

The best time for taking a nap is from 11pm to 13pm, and taking a rest of 15 minutes to half an hour at noon can help the body balance and transition, refresh the mind, and replenish energy.

5. Actively prevent related diseases

Hypertension, dyslipidemia, obesity, diabetes and other diseases will affect the function of the brain. Many of these diseases appear when people are young or even young, while others exhibit familial genetic tendencies. For high-risk populations, if detected early in the early stages of the disease, it can be effectively treated.

Taking precautions and avoiding controllable factors with high risk of diseases can greatly reduce the damage of these diseases to brain function in the future, achieving early detection, diagnosis, and treatment, in order to delay and control the development of the disease. Mild cases can involve adjusting lifestyle, improving nutritional structure, correcting unhealthy lifestyle habits, while severe cases can involve drug control. Of course, medication should be taken gradually and consistently.

6. Regularly do brain and finger exercises

Rubbing hands

Apply relative force to the palms, rub and massage for 1 minute, and the palms will feel a slight heat.

Pressing on the fingertips

Open the fingers of both hands and press the pulp of the other fingers with your thumbs in sequence to feel a slight pressure on the pulp.

Stretch one's fingers

Open one hand and slowly stretch the other hand towards the tip of the finger, starting from the base of the finger. With a slight amount of force, the finger feels a slight sense of stretching, which helps promote blood circulation in the fingers.

Open Finger

Starting from the index finger, clench your fists with both hands and open your fingers outward in sequence. This action allows you to apply a slight amount of force and feel the slight stretching of each finger.
