There are two main reasons for dizziness.
First of all, dizziness is mostly a manifestation of brain fatigue.
Using the brain for a long time will lead to the relative lack of blood supply to the brain when the brain is tired, and the lack of oxygen will cause cerebral vasodilation, thus regulating and improving oxygen supply. People will feel dizzy because of the expansion of blood vessels in the brain. In addition, when the brain is tired, it will also show inattention, decreased memory and dull thinking.
So, what causes brain fatigue and dizziness? There are mainly work pressure, long brain time, lack of sleep, mental stress, anxiety and depression. The dizziness caused by general brain fatigue can be obviously improved or recovered after rest.
Secondly, dizziness may be a sign of neurasthenia.
The common symptoms of neurasthenia patients are depression, doubt, dizziness, insomnia, forgetfulness, burnout and fatigue. Therefore, the cause of dizziness is likely to be related to neurasthenia. Experts suggest that dizziness caused by neurasthenia is generally difficult to improve after rest and can be distinguished from other factors.
Recommend several methods suitable for office workers to exercise.
grind one's teeth
It can stretch the muscles of the head, promote blood circulation in the head, refresh the brain, enhance memory, grind teeth repeatedly and promote saliva secretion. Saliva contains parotid gland, which has the function of delaying aging. Therefore, frequent gnashing of teeth can clear the brain and delay aging.
Lift your legs high
If possible, put your legs on the desk for a few minutes and have a rest. This will not only reduce the pressure on the veins of your feet and legs, but also greatly increase the blood supply to your head, so that you can relax and feel refreshed.
Shake your head-look satisfied.
The head is supported by the neck, and the role of the neck cannot be underestimated. The neck is composed of cervical joints, blood vessels and muscle ligaments. Shaking your head can make these organizations move. This can not only increase the blood supply to the brain, but also reduce the possibility of cholesterol accumulation in the carotid artery, which is not only conducive to preventing stroke, but also to preventing hypertension and cervical spondylosis.
Scratch one's ears and cheeks
All organs of the human body have nerve endings gathered in the ears. Pulling and massaging ears can stimulate various organs through nerve endings, adjust the mechanism of human viscera, improve the body and achieve the function of strengthening the body. At the same time, people's face is also rich in capillaries and lymph, with 10 arteries with sufficient blood supply, several highly vigilant nerves and 34 acupoints. Rubbing your face is equivalent to stimulating acupoints, massaging meridians, and promoting blood circulation and metabolism, making people feel happy and clear-headed.
spread
Office workers have little chance to do activities, and often sit for an hour or two. At this time, you might as well stretch yourself. Although this is an ordinary action, it will bring unexpected effects to the body. When the body is in a posture for a long time, a large amount of blood will accumulate in the veins of muscle tissue. At this time, stretching will make most muscles relax and contract, and a large amount of accumulated blood will be washed back to the heart, taking away some wastes in the muscles, thus eliminating fatigue.
