hypertension heat intolerance

Individuals with hypertension tend to have a reduced tolerance to heat, potentially due to the vascular hardening and increased cardiac strain associated with elevated blood pressure. In hot environments, the body's efforts to cool down by dilating skin blood vessels and increasing blood flow can exacerbate the heart's workload, leading to discomfort and potentially severe health issues. Specifically, in hot weather, hypertensive patients may experience symptoms such as dizziness, headache, chest tightness, and palpitations. This occurs because the dilation of blood vessels under high temperatures redirects more blood to the skin's surface, reducing blood flow to the brain and causing symptoms like dizziness and headaches. Additionally, the heart must work harder to maintain circulation, which can result in chest tightness and palpitations. In extreme cases, this can lead to serious conditions like heatstroke and heat-related illnesses. Therefore, it is crucial for individuals with hypertension to take precautions against heat exposure during hot weather, avoiding prolonged time in high-temperature conditions. They should also ensure proper indoor ventilation and use air conditioning or fans to lower indoor temperatures as needed. Furthermore, dietary adjustments are necessary to avoid foods high in salt and fat, which can negatively impact blood pressure control. Should any discomfort arise, it is imperative to seek medical attention promptly and adjust treatment plans under a physician's guidance.
