How Long Should You Be in a Hot Tub?

The sensation of relaxing in a hot tub is so appealing that you might just wish you could stay in the warm massaging waters all day and all night long. But that’s not a very good idea. Because the hot tub water temperature is higher than your internal body temperature, you will eventually begin to overheat. Spending too much time in the hot tub could result in serious health problems. So, how long should you be in a hot tub? We’ll cover this question and more over the course of this article.

How Long Should You Be in A Hot Tub?

The general consensus is that your hot tub sessions shouldn’t last much longer than 15 to 30 minutes. That said, there are a lot of different variables that come into play as we’ll discover below. But as a general rule of thumb, limiting your soaking sessions to under a half hour will do a lot to prevent any ill effects caused by overheating. However, it’s important that you pay attention to how your body feels and assess your situation accordingly. A certain amount of time in the hot tub on one particular day may feel comfortable, whereas on another day you might find the same amount of soaking time causes you to feel faint. You should react accordingly.

Factors That Will Affect How Long You Can Spend in A Hot Tub

As mentioned above, there are many different variables that will affect how long you can safely remain in the hot tub. Some of these factors may not affect you personally but can still have great consequences for those who are sharing the hot tub with you. Therefore, it’s important to understand how hot water affects different people so that you’re able to recognize if someone is in danger of overheating.

Water Temperature

Most hot tubs have a maximum temperature of 40 degrees Celsius (104 degrees Fahrenheit.) It only stands to reason that the hotter the temperature of the water, the less amount of time you’ll be able to spend in it without overheating. At maximum temperatures you shouldn’t spend more than 15 minutes at a time in the water. Of course, after your 15 minutes you can always get out and allow your body to cool down before resuming your soaking session. But if you want to spend more uninterrupted time in your hot tub, you could simply reduce the temperature of the water. This won’t happen instantaneously, so keep an eye on the thermometer to ascertain the actual temperature.

Air Temperature

The ambient air temperature will have an effect on both the water temperature and your body temperature. On a scorching hot, sunny day it’ll likely be difficult to spend a lot of time in 40 degree hot tub water. The sun will not only increase the temperature of the water, but it’ll have an effect on your body as well. Conversely, you may be able to spend more time in your hot tub in the middle of winter because of the cooling effect the weather will have on your body. Even though the water temperature may be the same, the surrounding environment will make a difference.

Personal Factors

Pregnant women and infants shouldn’t use a hot tub running at top temperatures. Pregnancy can cause hormonal and blood supply changes that can make it difficult for the body to properly thermoregulate. The heat can also negatively affect the fetus. Infants don’t yet have the same thermoregulation abilities as an adult and should not use a hot tub. It’s recommended that children be at least 5 years old before being allowed to use the hot tub and even then, the session lengths should be greatly reduced. If you have a medical condition, such as diabetes or heart problems, it’s best to speak to your doctor about using a hot tub. The same goes if you’re using medication that may cause drowsiness or affects your body’s ability to regulate its temperature.
