What is sleep shirtless?

Sleeping shirtless means sleeping without wearing a shirt or any upper body clothing. Many people find sleeping shirtless comfortable and beneficial for their sleep. This is because sleeping without a shirt allows the skin to breathe and helps regulate the body temperature, which can lead to a more restful sleep. Additionally, sleeping without a shirt can be beneficial for those with skin sensitivity or certain skin conditions. It is also important to note that sleeping shirtless is a personal choice and should be done in a safe and comfortable manner.
