Will blood pressure rise if the weather suddenly drops?

Under normal circumstances, when the weather is hot, blood pressure will not increase, but may actually decrease. The main reason is that when the weather is hot and the oxygen supply is sufficient, the blood circulation is accelerated and the pressure on the blood vessels is relatively small, which may lead to low blood pressure. And if you stay in a closed environment or perform high-intensity labor when the weather is hot, it may lead to an increase in blood pressure. This situation is mainly related to the reduction of oxygen in the air, and the heart reflexively speeds up in order to increase the blood supply and oxygen supply to the body, resulting in an increase in blood pressure. It is recommended that you measure your blood pressure on time every day, and drink more water and take rest when the weather is hot.
