What material is best to sleep in/on?
|
A common material used to sleep in is cotton. Cotton is soft, breathable, durable and extremely easy to clean. However, it doesn’t insulate well and collects moisture very often. So if you sweat a lot in your sleep, cotton may not be the material for you. Wool on the other hand is a great insulator. It’s also super soft, breathable and wicks moisture away. The only downside to wool is that it can be very expensive and itchy. So if you can afford it and have non-sensitive skin, try sleeping in wool. Linen is a material that is very breathable, good for warm climates, soft, and durable. However, linen wrinkles very easily which if severe enough, can lead to an uncomfortable sleep. Finally, polyester is the best material on paper for sleeping in and on. Polyester is durable, wrinkle-free, doesn’t absorb water, reasonably priced, and quick drying. Polyester has no major negatives about it. Although, the best material to sleep in and on is mainly up to personal preference. Everybody experiences different materials in different ways, and feels more comfortable and rested in some over the others.
