A night t-shirt or nothing at all
Short answer: A thin night t-shirt moves sweat away from the skin and keeps the sheet cleaner. With nothing on, the moisture sits between skin and bedding.
The moisture has to go somewhere
The body releases moisture all night. Without a layer it collects in the mattress and sheet. See night t-shirts for men.
Bedding lasts longer between washes
With nightwear, less sweat and skin oil reaches the sheet directly. That extends the time between washes. See bamboo bedding.
Thin rather than thick
A thick t-shirt makes you warm. A thin one in bamboo viscose moves moisture without insulating. See bamboo sleepwear for men.
In winter
In a cold bedroom a long sleeved style beats an extra duvet, because it does not overheat. See pyjama bottoms for men.
Frequently asked questions
Is it better to sleep with or without a t-shirt?
With, for most people. It moves moisture away from the skin and keeps bedding cleaner.
Does wearing clothes not make you warmer?
Not a thin layer. It is moisture against the skin that feels warm, not the fabric.
How often should nightwear be washed?
After three to four nights. More often if you sweat heavily at night.
