Dehydration can lead to high blood pressure through several mechanisms. When you don’t drink enough water, the body tries to conserve fluid, leading to a rise in sodium levels. In response, your body releases vasopressin, a hormone that helps retain water but also causes blood vessels to constrict, increasing blood pressure. This becomes even more problematic for those who already have high blood pressure. In view of this, it is very crucial to stay hydrated for overall well-being and to manage blood pressure levels. Regular fluid intake is vital to avoid the complications of dehydration.
