How often should nightwear be washed

Short answer: Every third or fourth night with normal use. If you sweat at night or sleep without underwear, every second night.

What builds up

Nightwear absorbs sweat, skin cells and skin oils for eight hours a night. After three nights the amount is noticeable, both in smell and in how the fabric feels. It is not a hygiene problem before then, but it is not pleasant either.

When to wash more often

If you sweat at night, have a fever or sleep without underwear, nightwear should be washed every second night. Choose thin qualities that dry quickly so it stays manageable. See bamboo nightwear for women.

What you need to make it work

Three sets allow weekly washing with normal use. Four or five if you change every second night. See bamboo nightwear for men and bamboo nightdresses.

Frequently asked questions

Can nightwear be aired between uses

Yes. Hang it spread out in the morning rather than tucking it under the pillow.

Should nightwear be washed with bedding

You can, but bedding is often washed hotter. Wash for the more delicate item.

How hot should nightwear be washed

Thirty degrees is enough. Forty if you have been ill.
