It is a very reasonable headline, heat exhaustion/heatstroke can kill. People in the uk have not been able to adapt to an extremely hot temperature because our weather is mostly moderate and not hot
Be aware of the symptoms, some of which are losing appetite. pale clammy skin, headache. There are more symptoms
Bear in mind that as we age, we do not get thirsty until we are very dehydrated and by then the blood is thick, cannot flow freely and clots are more likely to happen
It is important to cool the inner temperature, drink enough, move slowly etc
On monday my dd had to deal with someone with heat exhaustion and yesterday with someone who had a stroke. Heat exhaustion should not be taken lightly, or flippantly even though it is july
