When using a hot tub, make sure to stay hydrated and only use the hot tub for 10-minute intervals. While you can use the hot tub for more than 10-minutes a day, you should aim to keep your usage time between 15-30 minutes, especially in high temperatures. When using the hot tub for intervals longer than 10-minutes you should get out and take breaks consistently. If you feel dizzy, overheated, or unwell for any reason, get out of the tub immediately. You should make sure the temperature of your hot tub never goes above 104 degrees Fahrenheit.
