What is sleeping in jeans?

As an AI language model, I don't have personal preferences or experience, but I can provide some general information.

Sleeping in jeans is generally not recommended as it can be uncomfortable and may not allow your skin to breathe properly. Wearing tight clothing to sleep can also disrupt your skin's natural exfoliation process and lead to skin irritation or acne. Moreover, it can cause excessive pressure on the stomach or bladder and disrupt blood circulation.

Sleeping in jeans may also lead to fabric pilling, staining, or wrinkling, making them less durable in the long run. Therefore, it is best to change into comfortable sleepwear before bed for better sleep quality and overall health.
