Cold-water immersion has become a popular trend for its potential health benefits, but a new study found that the science behind it is inconclusive. While some people swear by its benefits for muscle soreness, immunity, and sleep, researchers say that the evidence is time-dependent and slim.
Experts agree that cold-water immersion can be tried, but it’s best to start slow with warmer water and short time periods. Researchers reviewed 11 studies on cold-water immersion and found that it may have some benefits, but many questions remain. The team discovered that cold-water immersion causes an immediate increase in inflammation, which might seem contradictory given its use by athletes to reduce inflammation.
However, the study also found that cold-water immersion wasn’t linked to immediate stress reduction, but it was associated with a drop in stress levels 12 hours later. Additionally, there is no immediate immune boost, but one study showed that people who took regular cold showers had fewer days off work due to illness.
The report concludes that more research is needed to understand the effects of cold-water immersion on the body. While some benefits may be seen over time, the scientific evidence is still developing. Experts recommend exercising caution and starting slow when trying cold-water immersion, especially for those with certain health conditions or circulatory issues.
It’s essential to note that experts agree that anyone with a heart condition, history of stroke or seizure, or respiratory condition should not participate in cold-water immersion. Those with Raynaud’s or other circulatory system issues should consult their healthcare provider before trying it.
