We know that cold water boosts your immune system and also rebalances your nervous system. It switches your nervous system from the sympathetic state (stress / anxiety) to the parasympathetic state (calm / focused) after just 4 minutes of submersion.
Take it slowly and don't try this without supervision (especially if the water is cold). In Ireland our sea is cold throughout the year, but it gets really cold from October - March.
I have trained to endure extreme temp shifts, but you can start in your shower with a minute or two of cold to conclude.
There has never been a better time to invest in your immune system and your own resilience.
