Heat can cause hypotension, especially in people with heart disease, or in children and the elderly, who may have their cardiovascular health impaired as a result of not drinking enough fluids.
During the summer, and with the high temperatures that usually occur, it is vital not to neglect hydration. It is very important to focus on monitoring risk groups such as the elderly or children, and especially patients with cardiovascular pathologies, as the latter may have their symptoms worsened as a result of heat and insufficient fluid intake.
High temperatures can cause cases of hypotension, especially in people who already have low blood pressure for the rest of the year, and in those who take medications to control it, which often add to the problem of being photosensitive. Therefore, it should be borne in mind that, although heat is not a risk factor as such for the heart, it can contribute to worsen the situation of people with arrhythmias, cardiac insufficiencies or ischemic cardiopathies, according to doctors.
To prevent dehydration from affecting our cardiovascular health, it is crucial to be aware of the first symptoms that indicate that our fluid level is low. These include dizziness, dry mouth and skin sensation, headache, lethargy and quite a bit of muscle weakness, and Dr. also advises following a heart-healthy diet.
The Mediterranean diet is a good example, as it is considered a great ally to combat heat by including lots of fresh fruits and vegetables. You should also drink plenty of fluids throughout the day, either in drinks or meals, such as gazpacho or watermelon. Drinking alcohol is not recommended, as the body consumes a lot of water to metabolize it, increasing the risk of dehydration.
Finally, it is not recommended to exercise during the hottest hours, even if this advice is for everyone, regardless of whether they have cardiovascular problems or not, because it can lead to heat stroke caused by overexertion and excessive fluid loss. The risk involved should not be underestimated, as the failure of the body to regulate itself can have very serious consequences.
