  How about drinking salt water?

  Physiological research suggests that breathing, sweating, and other physiological activities are still ongoing and consume a lot of water.

When you get up in the morning, the blood is concentrated. Drinking salt water will increase hypertonic dehydration and make people feel dry.

At the same time, early morning is the first peak of blood pressure in the human body. Drinking salt water will lower blood pressure and increase health, which is not good for health.

Experts suggest that drinking boiled water in the morning is the best choice. It can not only replenish lost water, but also effectively replace blood.

  Can you take a deep breath?

  At the remote end, scientific research and clinical observations have found that in patients with hypertension and coronary heart disease, excessive deep breathing can induce cardiac and cerebral vasoconstriction, which is fatal. Myocardial infarction, cerebral hemorrhage and other accidents are directly or indirectly related to deep breathing.

Therefore, experts suggest that it is best not to carry out deep breathing exercises for patients with arteriosclerosis, especially hypertension and cardiovascular and cerebrovascular diseases.

  Can you step back?

  Stepping back or running back can stimulate muscles that do not move often and improve the balance of the human body. Therefore, many elderly people like to step back during morning training.

Because the elderly’s cardiovascular reserve capacity is diminished, walking or running backwards can cause cardiovascular overload.

  At the same time, it causes a turn, which results in compression of the carotid artery, narrowing of the lumen, and reduced blood flow, resulting in reduced blood supply to the brain, hypoxia in the brain, and may even faint when the neck is turned.

For the elderly, stepping back once in a while will not hinder health, but it should not be done often.
