What is the 1 10 1 rule for cold water?
It’s called the 1-10-1 rule. It refers to you having one minute to control your breathing, less than 10 minutes for self-rescue, and 1 hour before you become unconscious due to hypothermia. Hypothermia is when your body loses heat faster than it can produce it. Long-term immersion hypothermia may set in after 30 minutes, depending on water temperature, clothing, body type and behavior in the water. Hypothermia occurs when the body loses heat faster than it produces, cooling vital organs. Cold water robs the body of heat 25 times faster than cold air.The body cools 25 – 30 times faster in cold water than in air. The 1:10:1 rule means you have 1 minute to get your breathing under control; 10 minutes of purposeful movement for self-rescue; and 1 hour before you succumb to hypothermia. Remember to be safe while enjoying activities on the ice!In the military we used the 120 rule. If water temperature plus ambient air temperature is above 120 degrees F then you can swim without a wetsuit for about an hour without getting hypothermia. So if the water is above 37, you’re good for an hour before you risk serious injury/death.

Is it healthy to swim in cold water every day?
Cold water swimming is a great immune system booster. Some studies have shown that water swimmers suffer fewer and milder respiratory infections and illnesses including the common cold (3,4). Cold water exposure also releases leukocytes into our bloodstream, a blood cell that helps fight disease and infection (7). Initial evidence suggests that cold water therapy may play a role in enhancing autophagy [141], thereby facilitating the removal of damaged organelles and proteins. The activation of autophagic pathways by cold exposure aligns with its potential to modulate cellular aging processes [142–144].

However, the number of laps you should swim depends on your fitness level and swimming ability. Beginners may start with swimming just one or two laps and gradually increase over time.
