When it comes to swimming, it’s essential to choose the right attire that is suitable for the aquatic environment. While cotton clothing may be comfortable and breathable for everyday wear, it is good to know why they are not allowed in pools.

From my experience, cotton clothes are not allowed in pools because they absorb sweat, and other bodily fluids from the skin, creating a breeding ground for bacteria and potentially causing skin irritations or infections. Conversely, go for synthetic fabrics like polyester and nylon for a more slick swimming experience.
In this blog post, I will explain the reasons why cotton clothes are not allowed in pools and highlight the alternatives that are more suitable for swimming.
5 Reasons Cotton Clothes Are Prohibited in Pools

There are several reasons for the prohibition of cotton clothes in pools, some of them are the following;
1. Hinders swimmer from staying afloat
Cotton has a high water absorption capacity, meaning it can quickly soak up moisture from its surroundings. When cotton clothing becomes saturated with water, it becomes heavy and can weigh the swimmer down. This added weight can negatively impact a swimmer’s ability to stay afloat and move through the water efficiently.
2. It impedes mobility
Wearing cotton clothes in the pool can significantly hinder mobility and restrict movement. When wet, cotton fabric tends to cling to the body, creating drag and making it harder to swim. The fabric can become tight, reducing the swimmer’s range of motion and impeding their ability to execute proper swimming techniques. This can be frustrating for competitive swimmers.

3. Prolonged drying time
Due to its absorbent nature, cotton takes a long time to dry compared to synthetic fabrics specifically designed for swimming. If you were to wear cotton clothes in the pool and then change into dry clothes afterward, the wet cotton fabric would retain moisture and remain damp for an extended period. This prolonged drying time can lead to discomfort and even contribute to the growth of bacteria and mildew, resulting in an unpleasant odor.
4. Hygiene concerns
Cotton clothing worn in pools can introduce various hygiene concerns for both the swimmer and the pool itself. As cotton absorbs and retains water, it also absorbs sweat, oils, and other bodily fluids that can be present on the skin. This combination of sweat and bacteria can create a breeding ground for germs, potentially leading to skin irritations, infections, or the spread of waterborne illnesses.
5. Impact on pool water
Using cotton clothing in pools can have adverse effects on the water quality and the pool’s infrastructure. Cotton fabric releases lint, fibers, and dyes when submerged in water. These particles can clog filters, impede water circulation, and add to the maintenance cost of the pool.
Suitable Alternatives for Swimming Aside Cotton Fabric
Now that we understand why cotton clothes are not suitable for pools, it’s essential to explore alternatives that are designed specifically for swimming. Here are some popular options:
1. Wear fabric with quick-dry properties
Polyester is a common fabric used in swimwear due to its durability, quick-drying properties, and resistance to chlorine and fading. You can also go for nylon for its stretchiness, smooth texture, and ability to retain shape even when wet. Alternatively, try Spandex or Lycra.
2. Rash guards

Rash guards are lightweight, quick-drying tops worn for sun protection and to guard against skin irritation. They are typically made from synthetic materials such as polyester or nylon and provide UPF (Ultraviolet Protection Factor) to protect against harmful sun rays.
3. Board shorts

Board shorts are loose-fitting shorts made from quick-drying fabrics like polyester or nylon. They are designed to provide comfort, mobility, and protection for activities both in and out of the water.
4. One-piece or two-piece swimsuits

One-piece and two-piece swimsuits made from synthetic fabrics offer excellent mobility, durability, and quick-drying properties. They are designed specifically for swimming and provide the necessary support, coverage, and comfort for active water activities.
Can I wear a cotton shirt in the pool?
No, it is not advisable to wear a cotton shirt in the pool. Cotton absorbs water, becomes heavy, restricts mobility, and can compromise pool hygiene.
What happens to cotton in chlorine?
Cotton fabric can undergo degradation and fading when exposed to chlorine, which can affect its structural integrity and color quality.
Conclusion
Cotton clothes are not allowed in pools due to their water absorption, weight, reduced mobility, prolonged drying time, hygiene concerns, and impact on pool water quality. To ensure a safe, hygienic, and enjoyable swimming experience, it is crucial to choose swimwear specifically designed for the aquatic environment.
