Planning the right temperature for a swimming pool is essential, especially for the Olympics. Olympic pools are kept between 25-28° Celsius, or 77-82.4° Fahrenheit. This is slightly cooler than most public pools, usually between 78° and 88° Fahrenheit. This temperature is chosen carefully. It helps swimmers' muscles stay warm without causing problems like dehydration, cramps, or overheating. Pools that are too hot or too cold can be dangerous. If a pool is too hot, a swimmer might overheat. If it's too cold, it could even lead to a heart attack. When you first jump in, the pool might feel very cold. But it feels just right once you start swimming and your body heats up. This is similar to how it feels when you run outside in cold weather.
