Cold winter temperatures are the cause of dangerously high blood pressure in the elderly. A French study has found that blood pressure fluctuates significantly according to the seasons. In winter, blood pressure in the elderly increases by 33.4 percent while in summer by 23.8 percent.
Although experts have failed to determine the mechanisms that may explain this link between weather and tension, they say it all has to do with the sympathetic nervous system. This system controls how the body reacts to stress. It also regulates the release of the catecholamine hormone that raises blood pressure by speeding up the heartbeat and keeping blood vessels under control.
Blood Tension Depending on the Seasons
French researchers analyzed the medical records of over 8800 adults over 65 years in the time span of 2 years. During the winter the systolic blood pressure increased by 5 points. The highest effect of temperatures on blood pressure was observed in the elderly over 80 years of age. These findings, according to experts, may also explain the seasonal effects on diseases such as ischemia, or problems with blood vessels affecting the elderly. More careful monitoring of the elderly’s blood pressure during the winter can improve their health.
How To Protect Yourself From The Impact Of Weather
Minimize exposure to the cold outdoors, Avoid strenuous physical activity, Wear thick, Wear gloves and scarf when outdoors, Avoid caffeine and alcohol as they cause faster loss of body heat.
Consume foods suitable for blood pressure such as fruits and vegetables. Limit your salt intake and eat more low-fat dairy products but also whole grains, fish, poultry and nuts. People working outdoors need to be extra careful to reduce the risk of high blood pressure./AgroWeb
