I’ve been taking cold dips each day in the sea while living overseas. I’m back in the states now and in my hometown, the land of Mickey Mouse, where the temperature of the Gulf is about 20 degrees warmer than overseas so my cold water dips are not so cold right now. I think the sea temp overseas in my town is about 57F right now and is great for waking me up and cooling down my aching joints but here it just feels a bit cool. It is probably still good for cooling the body down but doesn’t have that same jolt that I have in the sea on the other side of the Atlantic. I usually take the dip over there with the local contractor. I was taking them alone, but had a hypothermia incident one day and felt that it was a better idea to take the dip with a friend. We had to call an ambulance that day when I stayed in the 55 F water for 30 minutes and I don’t want to have to go through that kind of ordeal again. I think the ambulance had the air conditioning on in the back where they were treating me so it was a bit uncomfortable for me, especially after entering the ambulance shivering cold. Maybe they needed to keep the ambulance cold for a certain reason and it didn’t help that I only had on a light jacket and shorts after my swim. The moral of the story is don’t go in cold water too long on a cold cloudy day.
