Why does qi and blood deficiency lead to chest tightness and shortness of breath?

I often hear the word deficiency of both qi and blood, but what is deficiency of both qi and blood? What should I do?

People with insufficient qi and blood look depressed and have a bad face. Many people will choose to buy some expensive creams or do some beauty care. In fact, regulating their qi and blood is more important than anything else. So what kind of performance is deficiency of qi and blood? How can I regulate qi and blood?

There is something wrong with the skin.

Normal people's skin is often shiny and elastic, and young people should have no wrinkles and spots. However, if your skin becomes rough and abnormal color appears, it often indicates that your blood is insufficient.

Dull eyes

Ordinary people's eyeballs should be clear and bright. People with insufficient qi and blood often have yellow eyeballs, bloodshot eyes and turbid eyes.

Hair withered and yellow

A person's hair is black, thick and supple, indicating that there is enough blood. On the other hand, if the hair is yellow, forked and dull, it means that the blood is insufficient.

Hands and feet cold.

If a person's hands, feet and heart are warm all year round, it means that he is in good health, but people with insufficient qi and blood will be cold because qi and blood can't support their palms and soles.

Exercise fatigue and chest tightness are difficult to recover.

During exercise, the body needs a lot of oxygen and a lot of blood supply. If people with insufficient qi and blood can't replenish qi and blood immediately after exercise, it will lead to chest tightness, shortness of breath and fatigue.

Longitudinal stripes on nails

Normal people's nails should be half-moon-shaped, but people with qi and blood loss are not, usually accompanied by vertical stripes on their nails. It is already obvious that the body is too cold and the body is overdrawn.

Finger flattening

Normal people should have elastic fingers and full fingertips. And some people with insufficient qi and blood often have weak fingers, flat fingers or thin nails.

Poor sleep quality

Normal people sleep well, fall asleep quickly, sleep heavily and breathe evenly until dawn. People with insufficient qi and blood are prone to insomnia, dreaminess at night, frequent toilet visits and snoring.
