Thus, we should wear light cotton clothes in summer to keep ourselves cool. Cotton is a good absorber of water, and hence it absorbs all the sweat coming out from our body and exposes this to the air. When the sweat is exposed to air, it evaporates thus leaving our body cooler and more comfortable.
So the correct answer will be cotton.

Cotton is the correct answer because it is a natural fiber that has excellent moisture absorption properties. When we sweat, our body releases moisture, and cotton fabric can absorb this moisture, allowing it to evaporate more easily. This makes cotton clothing comfortable to wear during hot and humid weather.

Here is a detailed explanation of why cotton absorbs sweat:

1. Natural Fiber: Cotton is a natural fiber that is derived from the cotton plant. It is composed of cellulose, which is a complex carbohydrate. This natural composition allows cotton to have certain properties that make it suitable for absorbing sweat.

2. Absorbency: Cotton has a high absorbency rate, meaning it can absorb and hold a significant amount of moisture. When we sweat, the moisture is absorbed by the cotton fabric, preventing it from sticking to our skin and making us feel uncomfortable.

3. Breathability: Cotton is also breathable, which means air can easily pass through the fabric. This allows for better ventilation and aids in the evaporation of sweat. When sweat evaporates, it helps to cool down our body temperature, keeping us more comfortable.

4. Soft and Comfortable: Cotton fabric is soft and comfortable to wear. It is gentle on the skin and does not cause irritation or allergies. This is especially important when we are sweating, as sensitive skin can become easily irritated by synthetic fabrics.

5. Hypoallergenic: Cotton is hypoallergenic, which means it is less likely to cause allergic reactions or skin irritations. This is beneficial for individuals with sensitive skin or allergies.

6. Durability: Cotton fabric is known for its durability and ability to withstand regular washing and wear. This makes cotton clothing a practical choice for everyday use, including during physical activities when sweating is more likely to occur.

In summary, cotton is an ideal fabric for absorbing sweat due to its natural composition, absorbency, breathability, softness, hypoallergenic properties, and durability. It is a popular choice for clothing, particularly during hot and humid weather, as it helps to keep the body cool and comfortable by absorbing and allowing the evaporation of sweat.
