Recent hot weather On and off During this period Many friends with high blood pressure have found My blood pressure has dropped quietly. Why does blood pressure drop when the weather gets hot? Do you sometimes feel dizzy and black out? My blood pressure suddenly dropped. Can I reduce or stop taking the medicine? In fact, blood pressure has a seasonal rhythm. It is usually lower in summer than in winter . This is also true for patients with high blood pressure. Image source: Photo Network There are roughly two reasons for this: 1 Vasodilation When the weather is hot, the body's blood vessels dilate, and the lateral pressure of blood on the blood vessel walls decreases, which leads to lower blood pressure; 2 Decreased blood volume In hot weather, the body sweats and perspiration increases , which can lead to a decrease in blood volume; Image source: Photo Network (AI digital content) Food is easy to spoil in summer, and diarrhea and other discomforts are easy to occur after eating unclean food. As part of the body fluid and electrolytes are lost , the blood volume will also be relatively reduced; Some people, affected by the hot weather, have a decreased appetite and reduced intake , which can cause a relative decrease in effective blood volume and thus a drop in blood pressure. Healthy people If you are a healthy person with normal or low blood pressure , especially a young woman , low blood pressure in summer is mostly physiological.
