Although the brain only accounts for 2% of the body's weight, it consumes the largest amount of oxygen. Research results have confirmed that 15% of the blood supply from the heart is delivered 專注力不足解決方法to the brain to maintain the energy and oxygen consumption of the brain.
It can be said that the brain is an organ that is very afraid of hypoxia.
What happens when the brain doesn't get enough oxygen?
If the oxygen supply is insufficient, even for 5 seconds, the brain will change! The first is trance and dizziness. If there is ischemia and oxygen deprivation for 15 seconds, you may faint. 記憶力衰退原因If there is ischemia and oxygen deprivation for 5 minutes, the brain will be irreversibly damaged. You can see it with magnetic resonance imaging and CT scan. Brain cavity!
Oxygen is so important to the brain, yet many of us believe that there may be chronic brain hypoxia for a long time without even realizing it! Generally speaking, the typical early clinical symptoms of chronic brain hypoxia are poor sleep and memory loss. It may later lead to dizziness, headaches, memory loss, lack of concentration, 記憶力衰退原因insomnia and other problems.
If you encounter the above analysis problems and cannot find a clear cause, you should continue to be vigilant!
Brain-damaging bad habits
If you like to stay indoors but don't like to open windows for ventilation, this will reduce the indoor oxygen concentration and easily lead to cerebral hypoxia. The concentration of oxygen in the general atmosphere is about 21%!
If you stay in such a closed room for a long time, hypoxia problems will inevitably occur, and symptoms such as headaches, emotional instability, and insomnia will appear. Over time, it may also lead to brain atrophy.
If there are many designers in a bedroom, there is no ventilation, and the space is small, the situation will be more serious!
It is necessary to replenish oxygen to the brain and open windows for ventilation.
This is the fastest way to increase indoor oxygen levels in our country. Therefore, windows should be opened for natural ventilation at least twice a day, with each activity lasting no less than 15 minutes. The home should also be ventilated for 20 minutes in the morning, noon and evening every day when the ambient air is good.
Elderly people should pay more attention when taking a bath. Confined spaces can easily lead to cerebral hypoxia and accidents.
Do aerobic exercise
Aerobic exercise can promote blood circulation and help the body make better use of oxygen.
Long-term persistence in jogging, brisk walking, swimming and other aerobic training is very necessary.
But avoid excessive exercise, otherwise it will easily lead to chest tightness and asthma, leading to ischemia and hypoxia in the brain and heart.
In addition, going out regularly to breathe fresh air and relax yourself is also beneficial to brain health education.
If you don't have time to exercise, take some deep breaths in a place with fresh air. This movement helps your body get more oxygen.
Tips for strengthening your brain: plant some green plants
When exposed to sunlight, green plants absorb carbon dioxide and release oxygen during photosynthesis. If you are worried that plants will compete with us for oxygen at night, you might as well raise a pot of tiger orchid, which can also produce oxygen in the dark.
Be careful not to eat too much
After overeating, the digestive system is under tremendous stress and the body will allocate more blood to the intestinal mucosa for digestion of food.
In this way, the blood supply to other tissues will be relatively reduced and they will be in a state of hypoxia. The key to a balanced diet is to eat seven to eight times full and reduce socializing at night.
