If you’re ready to join the ranks of the ice bathers, here’s what you need to know to get started. The most important thing is to ease yourself into it and start slow.
How cold is too cold?
An ice bath should be 50-59°F (or 10–15°C) (14). Any colder than that could be unsafe unless your doctor has given a go-ahead. You should also limit your time in the ice bath to 10 to 15 minutes. (If you’re trying an ice bath for the very first time, start with 1 to 3 minutes and gradually increase from there.) Use a thermometer to make sure your water is at the right temperature.
Can I just take a cold shower?
A cold shower may not be as cold as an ice bath, but it can still have health benefits. Some pros suggest warm-to-cold showers: start out showering in warm water and gradually lower the temperature over the course of a few minutes. However, if you’re jumping into the shower straight after a workout, you may want to skip the warm water and go straight for the cold.
Is it safe for people of all ages?
Parents should get the approval of a health professional before giving their kids an ice bath. Regardless of your age, ice baths do come with risks for people with certain health conditions or who take certain medications. Sudden temperature change is not safe for everyone. Remember, cold water constricts blood vessels. If you have heart disease, high blood pressure, diabetes, circulation issues, venous stasis, peripheral neuropathy, or cold agglutinin disease, do not take an ice bath before clearing it with your doctor. If you take any medications that may pose a problem, check with a pro about that too.
If you want to take an ice bath to soothe an injury, make sure that it is a minor one. Deeper injuries with underlying issues, like torn tendons, won’t get any better with ice baths, and their healing may even be delayed.
When in doubt, ask your doctor. It’s always better to make sure you’re being safe.
How do I get started?
First, fill up your tub (with cold water) to thigh level. Gather about a pound of ice cubes. Add a small amount at first, then slowly add more as you adjust to the temperature. You can start by just immersing your feet and calves, then build up to immersing up to your chest.
Do not stay in the ice bath for longer than 15 minutes. When you’re just getting started, don’t worry about sticking it out for too long—just stay immersed as long as you can, and know that next time you’ll be able to make it even longer!
After your ice bath, let your body warm back up at room temperature. If you still can’t get warm again after several minutes, take a shower with warm water.
