Proper sunbathing helps prevent strokes

Proper sunbathing helps prevent strokes

American Stroke Association International Conference in 2012. Researchers at the University of Alabama (USA) evaluated more than 16,000 men and women. They filled out a detailed questionnaire about where they had lived all their lives. The researchers used a program developed by NASA, which takes into account latitude and longitude, clouds, pollution and other factors to calculate exposure to sunlight.

Every six months, for five years, people were contacted and questioned about your health. Of the 16,000 people, 351 suffered a stroke. An analysis of the data, which took into account a number of factors that may affect the risk of stroke, also indicated that people living in areas with lower exposure were on average 60% more susceptible to stroke. Researchers believe this relationship happened because solar radiation is primarily responsible for vitamin D synthesizing in the body.

The link between vitamin D and brain was endorsed by the second study. In this, more than 30,000 people were divided into three groups that ingested different amounts of vitamin D and dietary supplementation. People who ingested larger amounts of vitamin were 13% less likely to have a stroke and had a 25% lower chance of experiencing cognitive dysfunction compared to those who took the minimum amount of vitamin D.

The results of both studies indicate that sunbathing properly can do well for health. But researchers also associate findings with increased exercise in sunny areas and the health benefits of vitamin D as a whole.

Avoid stroke

Stroke is responsible for the deaths of five million people worldwide every year, according to WHO. In Brazil, the disease kills more than the heart attack: more than 100,000 people a year, according to the Ministry of Health. It is possible to prevent a stroke, since most of the risk factors for the clinical picture can be avoided. Know these factors and know how to fight them, as well as being aware of the symptoms.

High blood pressure

High blood pressure is at the top of the list of major causes of stroke. Neurologist André Lima explains that the internal walls of the arteries suffer trauma and injury from the flow of blood. "These can obstruct the passage of blood (ischemic stroke) or rupture the artery wall (hemorrhagic stroke)," explains neurologist André Lima of Barra D'or Hospital. It is possible to control hypertension with medication and healthy habits, such as reducing salt intake from eating and exercising.

Smoking

Cigarette substances cause blood clotting to increase. As a result, blood becomes thicker and blood flow in the arteries, in turn, is impaired, increasing the chances of a stroke.

Diabetes

Excess blood glucose - a characteristic of diabetes - increases blood clotting and leaves it more viscous. "This decreases the flow of blood from the arteries and can lead to a stroke," says André Lima. But it is worth remembering that these problems - including diabetes - can be controlled with regular medical treatment and healthy lifestyle habits.

Heart diseases

According to neurologist André Lima, cardiac arrhythmias may form small clots within the arteries and veins of the heart. "These clots can be sent to the cerebral arteries, causing an ischemic stroke," he explains.High Cholesterol

Excess cholesterol in the blood increases the thickening and hardening of the arteries. "Cholesterol plaques and fatty contents slowly deposit in the artery, causing it to close slowly and prevent blood flow," explains Maurício Hoshino, a neurologist at the Hospital das Clínicas in Sao Paulo. This process causes atherosclerosis - hardening of the arteries - and impairs brain oxygenation, increasing the risk of stroke.

Sedentary lifestyle and obesity

The practice of physical exercise is fundamental to control virtually all stroke risk factors. On the other hand, lack of this habit and obesity only increase the chances. "High blood pressure, high cholesterol, diabetes and heart disease are complications due to overweight and need to be prevented and controlled with good habits, which includes regular physical activity," said Maurício Hoshino.


Examination for detection of prostate cancer can reduce number of biopsies

Examination for detection of prostate cancer can reduce number of biopsies

Talk about prevention against prostate cancer prostate cancer can be complicated for some men, but it is necessary. In addition to rectal examination, screening for prostate cancer can be done by dosing a prostate-derived blood protein called PSA. When the level of PSA is high, it is often a sign that it is necessary to investigate possible diseases related to the prostate.

Sex after heart attack: what is the best time to do it again?

Sex after heart attack: what is the best time to do it again?

Elderly people and others who have had a myocardial infarction may have difficulty resuming sex. Among the factors that generate this difficulty, may be, for example, loss of physical conditioning, symptomatic limitations or fear and insecurity. In these cases, sexual activity should be considered as any other physical activity of moderate intensity.
