While people often associate cold-water temperatures with swimming hazards - with 70 degrees or lower being considered cold, and 60 degrees or colder potentially leading to hypothermia - it's important to note that water can also be too hot for a safe swim.

The ideal water temperature for swimming varies from person to person, but generally, most people find temperatures between 78 degrees and 82 degrees or slightly cooler to be comfortable.

The temperature of water can have a significant impact on the body, influencing factors such as stroke speed and heart rate.

At what point does heat become dangerous?

When water temperatures hit 90 degrees, overheating, dehydration and exhaustion can occur, potentially leading to heat stroke.

If you experience these symptoms while swimming, it's crucial to seek shade, rest, and hydrate.

Note that hot tubs, often reaching temperatures of 106 degrees or higher, are too hot for the body.

When exercising, consider swimming during cooler parts of the day, like early morning or evening, when the sun's intensity is lower.
