In daily life, people have been getting body-building according to, according to the customary manners, however, the latest research shows that, some fitness methods, for the different people, are not suitable for long-term adherence.
1, Take a deep breath
In recent years, scientific research and clinical observations show that, for the patients with hypertension and coronary heart disease, the excessive deep breathing may induce rapid cardiovascular and cerebrovascular contraction which may be potentially lethal, myocardial infarction, stroke, and other disease accidents are directly or indirectly related with the deep breathing.
2, Walk backward
Backward walking or running backward can stimulate the muscles which are not regular activities, to improve the body's balance. Therefore, many elderly people like backward walking when exercising in the morning. Because the cardiovascular reserve capacity of the elderly has reduced, backward walking or running will cause the cardiovascular overburdened. At the same time the neck will shift resulting in carotid artery oppressed, the lumen narrowed, blood flow reduced, these will directly lead to the reduction of brain blood flow and cerebral anoxia, possibly even faints when suddenly turning neck. So for the elderly, the occasional backward walking will not impede the health, but not be kept for long.
3, Drink saline
Physiological studies suggest that, some physiological activities like breathing and perspiration are still on when sleeping, and consumes a number of moisture. In the morning, the blood was on a concentrated state, drinking hypertonic saline will increase hypertonic dehydration, so people feel dry in their mouth. Meanwhile, the morning is the first peak of blood pressure elevation of the body, drinking salt water would make the blood pressure elevate even higher which is bad for your health. Experts suggest that drinking plain boiled water is the best option in the morning which can not only supple the loss of moisture, but also effectively dilute the blood.
