03/14 Drink plenty of water from a drinking fountain in hot weather
Our bodies are designed to function properly within a specific temperature range. Once outside this range, they can face problems. The term ‘hot’ is relative: different people are uncomfortable at different temperatures. Atmospheric conditions such as humidity and wind speed affect an individual’s perception of heat. Humid air prevents the evaporation of sweat and short-circuits the body’s cooling mechanism; in contrast, a breeze assists the evaporation of sweat and helps cool the body. In addition, the body becomes adjusted to what it perceives as a ‘normal’ temperature and any deviation from this causes discomfort. So it is important to listen to your body and adjust your behaviour accordingly. ‘Toughing it out’ is foolish and can have serious consequences. he most important thing in dealing with hot weather is being familiar with the symptoms of overheating and knowing how to treat it. Overheating can result in discomfort and heat cramps, heat exhaustion, or, most severely, heat stroke – which can be fatal. Hot weather can also aggravate existing health problems such as heart disease and respiratory illnesses, and these illnesses can compromise the body’s ability to deal with the heat. Hot weather is not just an inconvenience, and it needs to be approached sensibly.Heat cramps are painful spasms in the muscles of the arms, legs, and abdomen. These spasms generally result from strenuous activity and may be accompanied by heavy sweating. They seldom require medical attention unless a person has heart disease or is on a low-sodium diet. In every case, a person suffering from heat cramps should stop and rest in a cool environment, drink plenty of water from either a drinking fountain, water cooler or water coolers, and not resume strenuous activity for a few hours.
