Have you ever had your hot water heater break and been forced to take a cold shower? You may have done yourself a favor without even knowing it! Research suggests that short bouts of regular cold water exposure support the immune system.

Study Summary

A study found that daily routine showers at normal temperature followed by 30, 60 or 90 seconds of cold, resulted in a 29% reduction in self-reported sickness absence. A combination of the shower routine and regular physical activity reduced sickness absence by 54%.

Another study found that frequent cold water immersion 3 times a week for 16 weeks (1 hour per session, at around 57℉), slightly activates the immune system.

Cold water immersion and cold showers support the immune system likely by stimulating the body’s white blood cells and improving the body’s immune capacities to fend off illness.

The Hearty Take

At Hearty, we believe that cold water therapy or immersion confers healthspan benefits. To reap the immune benefits, create a cold shower routine. Finish your shower with 30-90 seconds of cold water.
