Your nightwear twists around you during the night
Short answer: Twisting comes from too much fabric and too little stretch. Choose a closer fit, shorter legs or a set cut to follow the body.
Why it happens
When you turn in your sleep, wide smooth fabric does not turn with you. It stays put and wraps around the body. Wide sleep trousers and long nightdresses are therefore the worst candidates.
Fit rather than more room
Many people buy nightwear a size up for room. That gives more folds to twist in. A set that sits closer but is knitted with stretch gives more freedom of movement and stays put. See bamboo nightwear for women.
The bedding plays a part
Slippery sheets make nightwear slide more. A sheet in bamboo or cotton with a little grip makes a noticeable difference. If you sleep warm you change position more often anyway, and then it counts double. See bamboo sheets.
Alternatives that work
Sleep shorts, a close fitting t-shirt or a short nightdress twist markedly less than long, wide pieces. See bamboo sleep shorts and bamboo nightwear for men.
Frequently asked questions
Is the smoothness of the fabric the problem
Partly. Smooth fabric on smooth sheets slides most, but the amount of fabric matters more.
Does elastic at the leg help
Yes. A soft elastic at the hem keeps the leg in place without pinching.
Is a nightdress always worse
Not necessarily. A short, close fitting one twists less than wide sleep trousers.
