Can You Sleep in a Swimsuit? No and Here’s Why

It might not be the biggest question in the history of the world, but it seemed like an interesting one to me: Can you sleep in a swimsuit?

Sleeping in a swimsuit is not recommended, as the chlorine and other chemicals used to clean your swimsuit can irritate your skin and cause irritation.

The best way to sleep in a swimsuit is to use a rash guard. A rash guard is a sleeveless shirt made of Lycra or spandex material that prevents you from having any friction against your skin when sleeping.

If you have sensitive skin then you may want to consider wearing a long-sleeve shirt under your suit. This will help protect your skin from any irritation caused by wearing a swimsuit while sleeping.

If you do choose to wear a rash guard while sleeping in your swimsuit, be sure to wash it often with warm water and soap or baby shampoo (if available). This will help keep germs away from your body while still allowing you to enjoy swimming and playing sports in the water.

Tight Clothes to Avoid Sleeping In

1. Synthetic Clothes

Clothes made from synthetic materials such as spandex, polyester or nylon are not ideal for sleeping. This is because it traps body heat and moisture, thereby forcing you to sweat.

Experts say there is no excuse for having a polyester or any other synthetic variety near your body or bed. These materials aside from their ability to obstruct your breathing, have been linked to rashes, itching, dermatitis and in some rare cases, a lower sperm count in men!

2. Underwear

Although wearing underwear to bed is a common practice among women, it is essential to state that this practice may be unfavourable to your health.

Covering your private part during the night may create an ideal condition for moist, dark and warm conditions for bacteria growth, especially for women.

If you are a woman who is prone to bacteria and yeast infection, sleeping with underwear is laying a foundation for many unwanted medical conditions especially if you are a consistent bedtime thong-wearer.

3. Bra

Sleeping with a Bra makes you uncomfortable and also vulnerable to different diseases. First, Bras can be constricting and if you are wearing one that fits tightly to your skin, you are preventing the free flow of blood around your body.

Bras can also squeeze and tighten the area around your chest, thereby exactly undue pressure on your chest which can make breathing difficult. Wearing Bra to bed increases your chances of developing a fungal infection.

Having a Bra on during your bedtime can also cause sleeplessness as it hampers your ability to achieve a night of truly deep sleep. Finally, a Bra’s hook, strap or underwire can dig into your skin, causing indentation, irritation and even welts.
