Hot tubs have seats at various levels for a reason–to allow you to move around and cool various parts of your body. If you sit at the lowest level for 15 minutes or more, you allow your core body temperature to rise a lot faster than it would if, say, you moved to a seat at which your upper torso was out of the water.

Most hot tub manufacturers suggest a time limit of 20 minutes per hot tub session. If the water is over 104 degrees or if individuals remain in the hot tub for more than 20 minutes, users increase their risk of heat-related illness and injury, including heart attack, stroke and brain damage.

We recommend you completely change the water in your hot tub at least once every three months.

Water temperature Sitting in hot water for a long time can cause severe heat-related illnesses, such as nausea, dizziness or fainting, and even death. Avoid staying in the hot tub for more than 10 minutes at one time.

Since the water in a hot tub is a higher temperature than your normal internal temperature, staying in a hot tub too long can cause you to overheat and experience symptoms like light-headedness, dizziness, or nausea.

Effects of too much chlorine For example, it may cause eye irritation, over-dried skin, and possibly some breathing problems. If theres too much chlorine it will vaporise and form gas that floats just above the surface of the water.

Taking a hot bath or shower (or spending time in a hot room) can lead to increased body temperature and cause blood vessels to dilate, which lowers blood pressure and can cause lightheadedness or dizziness.

The volume of blood your heart pumps will also rise, especially in a hot tub. That’s a result of the pressure of the water on the body, which increases the heart’s workload, he explains.

To prevent getting hot tub folliculitis from bath sponges, soak them in a gallon of water with ¾ cup of chlorine bleach for at least 5 minutes to kill any bacteria. Remove them and rinse them thoroughly before use.

INCREASES METABOLISM – Soaking in a hot tub simulates exercise as your circulation increases and your metabolism speeds up from sitting in the hot water. This relief can improve quality of life while making it easier to sleep, exercise, and stay active.

“Do hot tubs burn calories?” While hot tub weight loss might sound kooky, research has found that lounging for an hour in a hot bath burns the same number of calories as a half-hour walk.
