Hatters are preparing for the first heat wave of the summer as temperatures are expected to reach close to 40 degrees this weekend. And although many Hatters are looking forward to the hot weather, there are many who could be at risk. Dr Vivien Suttorp, The Medical Officer of Health for Alberta Health Services South Zone, says those people who are at highest risk are young infants, children, individuals with pre-existing medical conditions, and those who are working outside. Suttorp recommends that you protect yourself against ultra violet rays by wearing a wide brim hat, sunglasses and long sleeves. Also, anyone heading outside should wear sunscreen with an SPF of 30 or higher, stay hydrated by drinking lots of liquids, and avoid prolonged periods in the sun. Suttorp adds that if you start feeling dizzy or nauseous, you should get out of the sun immediately, and if the symptoms get worse, seek medical help
