AS THE hot weather continues, health experts have issued advice for keeping cool and healthy.

South West Hospital and Health Service Executive Director of Medical Services Dr Chris Buck said it was important to be be on the lookout for signs of heat-related illness.

"If you suspect someone is suffering from a heat-related illness - an extremely high body temperature, flushed, dry skin, a rapid pulse, headache and confusion - you should seek medical assistance immediately or phone Triple Zero (000),” he said.

Dr Buck said there were some simple measures to be taken to assist someone in distress from the heat.

"To help someone affected by the heat, cool the person down urgently with a cool shower, bath or sponge, or even spray them with cool water from a hose,” he said.

''Loosen their clothing and have them rest in a cool place.

”Provide cool non-alcoholic fluids, but only if you are confident they can swallow. Avoid drinks high in sugar and caffeine.”

He said it was timely to remind people to drink plenty of water to avoid dehydration.

"Our bodies are mostly made of water, so when the temperature increases our body tries to cool itself by sweating, making dehydration a real concern,” Dr Buck said.

"In severe cases, dehydration can result in shock, which affects blood flow in the body, and can even result in death.”

Dr Buck said it was important to drink water regularly throughout the day, and to not wait for feelings of thirst.

Looking out for those more vulnerable to the impacts of heat was important at this time of year.

"Some people are more prone to heat-related illnesses, including the elderly, infants, overweight and obese people, pregnant and breastfeeding women and people with some pre-existing health conditions,” he said.
