If the weather suddenly turns cold or the temperature difference between day and night is large, it will lead to dyspnea, numbness of hands and feet, chills and lack of oxygen. Excuse me, what symptom is this ~ ~
The mechanism of coma and death caused by severe hypoxia is that the membrane potential of nerve cells decreases and the synthesis of neurotransmitters decreases; The energy metabolism of brain cells is impaired, ATP is reduced and cell membrane permeability is increased; Acidosis, intracellular free Ca2+ increase, lysosomal enzyme release and cell edema lead to central nervous system dysfunction.
Don't wear tights if you feel lack of oxygen or your heart is uncomfortable! ! ! It's a little tight Can't wear it! ! ! Be sure to wear loose clothes! ! ! Do you know that too tight clothes will affect heart and lung function? Take more deep breaths, exercise and eat more fruits, such as apples. Don't hunch over, hunching over will also affect cardiopulmonary function! ! !
