This science-backed technique actually helps you sleep better

The pursuit of restful sleep is a daily challenge for many of us. Fatigue, stress, and anxiety can really disrupt our night’s rest. But, did you know that submerging in cold water could be the key to improving your sleep?

A study published in the journal Physiology and behavior Turns out that this exercise, which has long been linked to physical improvements, has positive effects on sleep quality and more.

Cold immersion, an effective therapeutic tool

Cold water immersion is becoming increasingly popular, especially among athletes and general health seekers. Studies have shown that exposure to water at 10 degrees Celsius for 10 minutes three times a week significantly improves sleep quality.

Participants who followed this routine showed a reduction in sleep disturbances. Their Pittsburgh Sleep Quality Index score dropped from 7.85 to 5.75 in just three weeks, proving that cold water can indeed promote more restful sleep.

significant reduction in anxiety

In addition to its effect on sleep, this technique is also of interest for stress management. The study results showed a reduction in subjective stress scores among participants after each immersion.

In fact, immersion in cold water stimulates an intense physiological response that helps reduce anxieties, providing immediate and beneficial relaxation to the mind.

subtle but promising results

Although cold immersion appears to promote sleep and reduce anxiety, the effects on overall mood are less clear. The study found no significant changes in the participants’ overall well-being, although their mental state did not worsen.

This suggests that while cold water can have a calming effect, other factors such as environmental and social context may play an important role.
