The Benefits of a Cold Tub For Recovery

Cold Tub For Recovery

Scroll through Tik Tok and you’ll find a growing number of videos of people submerging themselves in tubs of cold water, purportedly to help with muscle recovery. The wellness trend, called cold tub or cold water immersion (CWI), may have some scientific backing: Cold temperatures cause blood vessels to narrow and decrease blood flow to the muscles, which reduces inflammation.

However, if done too long, cold plunges can trigger hypothermia, which can lead to organ failure and death. So before you start trying ice baths at home, consult with your doctor or sports medicine specialist to make sure it’s safe for you.

The benefits of a cold tub are numerous, but the process of acclimation can be tough for newcomers to the practice. To prevent injury, Cottle recommends starting out with a cold shower and slowly working your way up to full body submersion. It’s also best to get in with a buddy, and have someone on hand to check that you don’t overdo it.

A cold tub can be a good way to improve your ability to cope with stress and anxiety, as well. “When you put yourself in a state of controlled stress through the cold water, it forces you to focus on breathing and remaining calm,” she says. “And if you can do that on a regular basis, it can help you with real-life stressors.”

Taking a cold shower or submerging in a Cold Tub before or after a workout can reduce muscle soreness by slowing nerve signaling and decreasing the amount of pain-causing molecules released by the muscles. It can also help prevent the onset of a post-workout crash or lethargic feeling by decreasing your blood sugar levels and increasing your heart rate, which can speed up your metabolism.

While research on CWI is limited, some athletes have reported that a 10-minute cold plunge after exercise helps them recover faster than simply resting or taking a hot shower. A few recent studies have even found that a soak in hot water may be better than an ice bath for athletes, but more study is needed.

Another potential benefit of a cold tub is its immune-boosting effects, though this hasn’t been proven by any specific studies yet. There is some evidence that a combination of cold exposure, breathwork, and meditation can activate the sympathetic nervous system and stimulate an epinephrine release, which can boost your immune response to fight infections and other health threats.3

This process is believed to aid in muscle recovery and reduce the severity of delayed onset muscle soreness (DOMS). Cold exposure also triggers the release of endorphins, the body’s natural painkillers, which can lead to feelings of euphoria and reduced stress. This combination of physical and psychological benefits has made the cold tub a go-to tool for those looking to enhance their recovery after intense physical exertion.

When a person submerges their body in cold water, the body reacts to the sudden temperature drop by constricting blood vessels. This is part of the body’s natural mechanism to preserve heat and protect vital organs. The constriction reduces blood flow to the extremities and muscles, which in turn decreases inflammation and reduces the perception of pain. As the body warms back up after exiting the cold tub, blood flow returns to normal, flushing out metabolic waste products like lactic acid and bringing fresh oxygen and nutrients to the muscles and tissues.
