Prevention
"With heat injuries, prevention is more important than cure because if you leave it too late, you may never get a second chance," say doctors from
Singapore General Hospital, a member of the
SingHealth group.
- Drink lots of fluids before, during and after training. Do not wait to become thirsty before you drink. Drink until your urine becomes dilute and clear.
- Avoid caffeine, alcohol and carbonated drinks. Plain water is the best; however, a good sports drink will also help to replenish salts and minerals lost through sweating.
- Wear loose-fitting clothes that allow for good air circulation, and do not restrict your movements.
- Avoid the extreme heat in the middle of the day. Schedule your training and playing sessions at cooler times, such as early mornings and evenings.
- Avoid sunburn at all costs. A huge amount of fluids is lost through burnt skin. If you have to be in the sun for prolonged periods, remember “slip, slop, slap”. Slip on a shirt, slop on some sunscreen, and slap on a hat.
- Schedule plenty of rest time in cool, shaded areas, as part of your training and playing.
- Do not be too ambitious in your training regime. Start slow and gradually step up to acclimatise to your current training and playing environment.
- Do not engage in strenuous sports if you are currently having, or have recently recovered from fever, flu-like symptoms and gastroenteritis. Inform your PE teacher or events organiser.
Lastly, do not ignore warning signs.
