We know that the normal body temperature is 37 degrees Celsius (or 98.6 degrees Fahrenheit). The load on the heart increases with activity and exercise, especially in hot weather. Studies have shown that drinking chilled water not only decreases the heart rate but also stimulates the vagus nerve. The hourly temperature had a significant lag effect on blood pressure, with the lag time of 0-5 h. Timely protective measures during cold weather are beneficial to maintain stable blood pressure levels. It can cause the blood to thicken which may lead to blood clotting (worst case scenario). So a change in outdoor temperature from 15 C to 24 C can cause the heart rate to increase by 2 . It can also lead to faster heart rates, thicker blood, and higher blood pressure.
