Look After your Heart
Everyone has been enjoying the recent hot weather, but it can have an adverse effect on your heart.
When the weather is hot, you sweat to cool down, but this means that you lose more fluid than usual from your body. This can drop your blood pressure and make your heart beat faster. This is not a problem for most people as long as they drink plenty of fluids. However, if you have a heart problem, extreme heat may place an extra burden on your heart and circulation, so it is particularly important to stay cool and look after yourself.
It is also important to recognise the difference between a heart attack and cardiac arrest - 5 differences noted.
