Swimming pool tiles are often blue because blue tiles can create a visually appealing and inviting appearance for the pool. Blue is also associated with water, and it can enhance the perception of cleanliness and depth in the pool. Additionally, blue tiles can complement the color of the water, especially in outdoor pools, where the color of the sky and surrounding environment can influence the overall look of the pool.

It's generally better to shower before you swim. This helps remove oils, sweat, and dirt from your body, which can reduce the amount of contaminants introduced into the pool water.

Showering after swimming is also important to rinse off any chlorine or pool chemicals that may be lingering on your skin.

Swimming in a pool with too much chlorine can lead to various health issues. The symptoms may include skin and eye irritation, burning sensation in the eyes, nose, and throat, coughing, and difficulty breathing. Inhaling high levels of chlorine gas, which can be released from chlorinated water, can also cause respiratory problems. Prolonged exposure to excessive chlorine levels may result in more serious health issues, such as asthma or other respiratory conditions. It's important to maintain proper chlorine levels in pools to ensure a safe swimming environment.

Swimming has been around for thousands of years, and it likely began when early humans who lived near water discovered that they could move in it and stay afloat. Over time, different cultures and societies developed their own swimming styles and techniques, leading to the diverse range of swimming styles we see today.
