Hot Tub Safety Tips
For safety, limit hot tub sessions to about 15–30 minutes, keep the water temperature at or below 104°F, and stay hydrated before and after use. Avoid alcohol, and get out right away if you feel dizzy, lightheaded, overheated, or uncomfortable. People who are pregnant, have heart conditions, blood pressure concerns, or other medical conditions should check with a healthcare professional before using a hot tub.
