If you can bear the initial icy shock, hopping into the icy sea or a cold bath can help lower stress or give you a better night’s sleep.

We’ve all seen athletes and rugby players dive into those giant ice baths after the big game or race. Sounds like Jackman is enjoying the benefits of a cold dip too!
