The Health Authorities issued a health warning this morning advising people to keep themselves hydrated in the hot weather.

High temperatures, it said, caused water to be lost from the body quickly, resulting in dehydration.

It could also lead to heat exhaustion or heatstroke. Older people, babies and young children, people with chronic conditions and physically active people were at a higher risk.

To avoid the effects of high temperatues, it was important to:

* Avoid unnecessary exposure to the sun during hot periods of the day, usually between 11am and 4pm;

* Stay in the coolest parts of the home and office;

* Drink regularly and eat more cold food;

* Seek medical advice if concerned.
