Generally speaking, patients with hypertension can still participate in sports activities under the supervision of doctors. However, winter swimming is a kind of sports activity in the strong cold environment. Under the strong cold stimulation of cold water, the blood vessels of the whole body's skin contract sharply, forcing the blood in the epidermal vessels to return to the viscera and deep tissues, thus causing a temporary increase in blood pressure. Hypertension patients have high blood pressure and are often accompanied by varying degrees of vascular sclerosis, especially those whose diastolic blood pressure is often more than 100 mm mercury column, which shows that the elasticity of blood vessels is reduced. If the blood pressure of patients participating in winter swimming will be temporarily increased, it is very likely to have cerebral vascular rupture, hemorrhage, stroke, coma and even death. Therefore, it is not suitable for patients with hypertension to exercise in winter swimming with strong cold stimulation. But patients with hypertension can take general cold water exercise. This is because when the body is exposed to cold water, the blood vessels in the epidermis contract, and the blood pressure rises slightly, but only for a short time. Soon, the blood vessels in the epidermis expand again, and a large amount of blood flows into the blood vessels of the skin. At this time, the blood pressure is slightly lower than when the body is not exposed to cold water. Long term adherence to cold water exercise, the blood vessels throughout the body after repeated stretching and contraction training, but enhance the elasticity, help to adjust blood pressure.
The best form of cold water exercise for patients with hypertension is to wipe the body with cold water. This is a kind of cold water a small amount of repeated contact with the skin way of exercise, stimulation intensity is not big, the body of hypertensive patients is easy to accept. At the beginning, the water temperature should not be too low, and then gradually reduce according to the degree of tolerance of the body. The technique should be light and the force should be even. First, wipe the upper body, and then, put on clothes and sit down to wipe the lower half of the body. Do not bow down, bend down and get up too fast. Hypertension with dizziness, the beginning with cold water to wash the face, and then cold water feet. Adhere to a period of time, symptoms have improved, and then use cold water to wipe the body.
If the following mild hypertension patients, depending on the situation, to participate in appropriate winter swimming exercise. One is adolescent hypertension. The reason is that some endocrine changes during sexual maturity are related to the rapid development of the heart during this period. This type of hypertension is mainly manifested in the rise of systolic blood pressure, up to 140-150 mm mercury column, and diastolic blood pressure is not high, generally no dizziness, headache and other adverse feelings, this type of youth do not have to taboo to participate in winter swimming. But the intensity of winter swimming should be reduced properly. Through the scientific and appropriate amount of winter swimming exercise, blood pressure will not rise, but also make it return to normal.
Another is excessive tension hypertension, this kind of hypertension is generally due to work fatigue, mental stress, excessive fatigue caused. This kind of hypertension not only systolic too high, can exceed 140 even 150 mm Hg, diastolic blood pressure also rises, can reach 90-100 mm Hg. This phenomenon can be reduced by reducing work pressure, reasonably arranging life and ensuring adequate sleep and rest. With the disappearance of excessive tension, blood pressure can return to normal. This kind of hypertension can also continue to participate in winter swimming exercise. However, it should be diagnosed clearly, consult doctors, strictly control the stimulation intensity during winter swimming, and strictly follow the scientific methods and health care requirements of winter swimming If you feel comfortable, stop immediately when you find discomfort.
