HYDERABAD : Can heat of the sun damage your heart? Can hot weather damage your heart? The answer is yes, it can. More so if you have mild heart problems already
How does hot weather affect your heart?
When the weather is hot our body sweats to cool down and bring the body temperature down. But in this process, the body looses fluids. This drop in the volume of fluids in the body can drop your blood pressure and make your heart beat faster.
Most people will tolerate this but if you have a heart problem, extreme heat may place an extra burden on your heart and circulation causing angina or chest pain and in some conditions increase heart beat or palpitations. Therefore it’s particularly important to stay cool and look after yourself.
If you have coronary heart disease, you may find you start to experience angina or chest pain which worsens during hot weather, because hot weather increases the workload on your heart and the demand for oxygen, especially when you are more active.
Losing too much body fluid can increase your internal body temperature, which could be life-threatening if left untreated. Symptoms of heat stroke include sweating, cold clammy skin, dizziness, fainting, muscle cramps, heat rash, oedema (swelling) in the ankles, shallow or fast breathing, nausea and vomiting. If you suspect that you or someone else has heat stroke, get medical attention immediately.
It’s particularly important to stay cool if you have heart failure - where your heart doesn’t pump as well as it should. If you’ve been told to restrict your fluid intake, speak to your doctor about other ways to keep cool during summer. If you take water tablets and start to feel dizzy or light headed let your doctor know. Your dose can then be reduced or stopped for a little while, if needed, until you feel better.
Who are mostly at risk?
Elderly people and very young children have more difficulty in regulating their temperature and so can be more at risk from extreme temperatures
