In sports therapy, an ice bath, or sometimes cold-water immersion or cold therapy, is a training regimen usually following a period of intense exercise While it is becoming increasingly popular and accepted among athletes in a variety of sports, the method is controversial, with a risk of hypothermia, with the possibility of shock leading to sudden death. Many athletes have used cold water immersion after an intense exercise workout in the belief that it speeds up bodily recovery; however, the internal physical processes are not well understood and remain elusive. Generally research into the health effects of cold water immersion as part of an athletic training regimen is inconclusive, with some studies suggesting a mild benefit such as reducing muscle damage and discomfort and alleviating delayed onset muscle soreness, with other studies suggesting that cold water immersion may slow muscle growth and interfere with an overall training regimen.

Intermittent fasting, also known as intermittent energy restriction, is an umbrella term for various meal timing schedules that cycle between voluntary fasting (or reduced calories intake) and non-fasting over a given period. Three methods of intermittent fasting are alternate-day fasting, periodic fasting, and daily time-restricted feeding. intermittent fasting is also regarded as a fad. The science concerning intermittent fasting is contested. The American Heart Association (AHA) states that intermittent fasting may produce weight loss, reduce insulin resistance, and lower the risk of cardiometabolic diseases, although its long-term sustainability is unknown. A 2019 review concluded that in humans, intermittent-fasting interventions may help with obesity, insulin resistance, dyslipidemia, hypertension, and inflammation.
