Heatstroke: Surviving the Summer Heat


The hot days of summer are now here! Summer is the hottest of the four seasons and depending on where you are in the world, the start of summer varies. In southern and southeast Asia, summer is officially declared during the months of March, April, May and June. This is also the time when we think of going on summer holidays to enjoy the warm sand and beach. If you have plans for a beach outing, picnics or other outdoor activities with family and friends, please be aware of these summer tips to keep your family happy and healthy.


Please be aware that according to the American Heart Association, “HEAT CAN BE HARD ON YOUR HEART.” Dr. Gerald Fletcher, a professor of Medicine at the Mayo Clinic says that “if you are a heart patient, older than 50 or overweight, you might need to take special precautions in the heat.”
