How long can you comfortably swim in water 69-72 degrees, on a warm sunny day?

Question

Anyone who lives by a lake or an ocean with experience.. thanks.

Answer 1

Water temperature is a very personal preference. My low-limit is 58, anything below that I wear a wetsuit. 69-72 is a great temp for distance swimming, you don't overheat and it's warm enough to keep your core temp from dropping substantially. In 69-72 degree water I would say you could stay in for hours provided you are moving, however, if you're simply lazing about or floating around you may get cold quicker. Just be smart and aware of your body's signals. If you feel cold, start moving or get out. If you're with someone else make sure you watch each other for signs of impending hypothermia like pale skin, blue/purple lips, white nailbeds and shivering.

One thing to be aware of with open water is the wind; exiting the water on a windy day can chill a person so make sure if there's an ocean breeze you have your towel close at hand!

I live on the Atlantic and I'm in the water just about year round. I've found that people who grew up in colder water are a lot more tolerant of colder temperatures than those who are not used to swimming in the ocean in say, February haha. However, the more you get in and swim in colder water the more tolerant you will become. The main thing is to be aware of your own body and don't force yourself to stay in too long, it's not worth the risk.

Another fun (or not...) way to teach your body to tolerate colder water temps is to submerge in a bath of cool water. It will make you shiver but you can get out right away and you will learn your body's responses.

Good luck!

the main severe techniques that the folk can wrestle international warming is getting rid of their older variety automobiles (1979 Buick) because of fact, older automobiles emmitt extra poisonous fumes into the air. Its obtrusive that the extra technological progressed a vehicle is, the fewer risky gases it emmitts. A vehicle that grew to become into outfitted 3 or 4 years in the past would be extra economic gadget friendly than a vehicle that grew to become into assembled 35 years in the past. for best populated cities inclusive of manhattan, Bus and Taxi companys might desire to replace present day automobiles with automobiles that are powered with the help of hydrogen or electrical energy. purely think of, if each substantial city used the Toyota Prius as taxi's, there may well be a decreased point of pollutants, and additionally taxi fares might desire to be considerably decrease as properly.

Depends on your body makeup, are you thin, stocky, the higher the body fat the longer you will last. I'm 6'3" 200lbs and I could stay in all day with not much of a problem.
