Freezing baths just might make for a happy heart.

When you submerge in cold water, blood rushes to your vital organs. Your heart then needs to work harder, pushing blood through your vessels and giving your bod the vital oxygen and nutrients it needs.

Keep in mind that going on a 10-minute walk can give you a similar blood-circulatory boost. Really don’t want to walk it out? Try an ice bath instead.

There is some scientific evidence that ice baths work as an immunity booster. One 2016 study published in the journal PLoS One found that people who take cold showers are almost 30 percent less likely to call in sick for work or school.

The cold water can have a positive effect on the central nervous system, which helps you sleep and feel better after spending ten to fifteen minutes in it.

Cold water immersion can also help athletes feellike they’rerecovering better. A 2017 study found that MMA competitors who dunked in cold water after working out reported being less sore than those who didn’t the same goes for NFL athletes across the board in all sports.

According to 2018 research, cold stimulation (specifically in the neck region) stimulates the vagus nerve, thereby lowering heart rate and potentially reducing stress.

In a 2014 review of hydrotherapy treatments, researchers concluded that cold exposure (like a cold compress or ice bath) can boost the capacity and function of your central nervous system (CNS). A functional CNS can help you sleep better and just feel better.

It can numb pain receptors and bring down inflammation, so you can almost think of it as like a drug-free anesthetic

Cold exposure increases the brown adipose tissue in the body, which is responsible for converting energy into heat to keep the body warm - this is what gives you the metabolism boost.
