Can I wear contact lenses while swimming in a pool?

It is best not to wear them. Pool water contains chlorine and other chemicals, and the soft contact lenses we usually wear can absorb these chemicals, irritating the human cornea and conjunctiva, causing symptoms such as eye redness, discomfort, and photophobia. Generally speaking, this irritation reaction is short-lived.

Natural bodies of water such as seawater, rivers and lakes are not chemically treated and contain more pollutants, which can cause eye infections.

Before swimming, you should do some warm-up exercises to fully stretch your muscles and joints to prevent leg cramps due to low water temperature after entering the water.

During swimming, the amount of exercise should be controlled within a manageable range to avoid excessive exercise causing muscle soreness.

What makes the water in the swimming pool blue?

Copper sulfate is added. Anhydrous copper sulfate is a white powder, but when dissolved in water, it forms a blue copper sulfate solution. Copper sulfate is added to the swimming pool because the presence of organic matter in the swimming pool will breed algae, and copper sulfate can inhibit the growth of algae and sterilize.

National standards stipulate that the copper sulfate added to swimming pools is 0.25~0.5 mg/L. Swimming pools are special places for swimming.

Swimming pools can be divided into general swimming pools and heated swimming pools according to the water temperature, and can also be divided into indoor swimming pools and outdoor swimming pools.

Should I shower before swimming?

Shower before swimming. Generally, the water temperature is lower than body temperature. Showering before swimming can make the body fully adapt to the water temperature and wash away sweat, dirt, cosmetics, etc. It can also make the hair and skin saturated with water in advance, effectively preventing the invasion of germs in the swimming pool.

Swimming is a sport in which a person floats upward under the buoyancy of water and uses the buoyancy to make the body move regularly in the water through the rhythmic movement of the limbs.
