Because change of temperature
Evapouration of the water on your skin requires heat, which it draws from your body, making you feel cold.
because your body hasn't adjust to the temp to the pool
because when you enter you body heat is not released
Because the air around you is hotter then water in the pool.
Generally because the water is cooler than your body temperature.
The water evaporating off your skin makes you feel cold and the wind helps evaporate the water faster.
Conduction. Heat travels from high to low to balance itself, in a cold pool our warm bodies will lose heat to balance the waters temperature.
It's all about how your body reacts to relative temperatures. The truth is that the pool temperature is not likely to be the culprit. It's more about how your body perceives the difference between the outside temperature vs the pool temperature. The transition from standing in the hot sun to getting into your pool makes the water feel colder than it might feel than if you are standing in cold rain before entering the pool.
we feel lighter when we are in a swimming pool. this is because of buoyant force or upthrust. it is the upward force acting on a body immersed in a fluid.
define water ^ what kind of answer is that? "define water." its a simple question. is swimming pool water cold? the water found in swimming pools. now for an answer, water temp varies between pools. some are cold and some are warmer.
It depends, how cold is the weather? if it is hot then probably not, but if it is chilly than it is probably not a good idea to go swimming anyways
