Training in Singapore Heat: Hydration and Electrolyte Tips
By Best Nutrition - Singapore · · 2 min read
Quick answer
Singapore’s heat and humidity make you sweat heavily, so drink water steadily through the day and during exercise, weigh yourself before and after long sessions to estimate fluid loss, and add electrolytes for sessions longer than an hour or when you sweat heavily. Train early morning or evening to avoid the hottest hours.
Why humidity makes training harder
Sweat cools you down when it evaporates. In humid air, sweat evaporates more slowly, so your body keeps sweating to try to cool itself. That means greater fluid and electrolyte losses, a higher heart rate and earlier fatigue.
Practical hydration habits
- Drink regularly through the day so you start training well hydrated.
- Sip water every 15 to 20 minutes during exercise.
- Weigh yourself before and after long sessions; each kilogram lost is roughly one litre of fluid to replace.
- Check your urine colour: pale yellow is a good sign.
When to add electrolytes
For sessions over an hour, outdoor runs or if you notice white salt marks on your clothes, an electrolyte drink helps replace sodium and encourages you to keep drinking. A zero-sugar BCAA drink with electrolytes such as XTEND Original is one option during training.
Warning signs of heat illness
Stop exercising and cool down immediately if you feel dizzy, confused, nauseous or stop sweating. Seek medical help for symptoms of heat stroke.
