If your body temperature gets too low, it can be dangerous because it can lead to a condition known as hypothermia.
Hypothermia occurs when your body loses heat faster than it can produce heat, resulting in a dangerously low body temperature. Cold temperatures can disrupt normal bodily functions. As your body temperature drops, your metabolism slows down, affecting important organ processes such as heart rate, breathing, and brain function. This can lead to confusion, lack of coordination, and difficulty thinking clearly. Concerningly, cold body temperatures place stress on the cardiovascular system. In cold conditions, blood vessels constrict, which can increase blood pressure and put pressure on the heart. Moreover, in the most extreme cases, hypothermia can result in organ failure.
