Is it normal to wear underwear in bed?
Yep.Totally normal
Yes, it’s completely normal to wear underwear in bed. Some people prefer it; others sleep without it—go with whatever feels comfortable to you.
Plenty of people sleep in underwear, while plenty of others find pajamas or sleeping without underwear more comfortable. There’s no one “right” way to do it, and wearing underwear to bed isn’t inherently unhygienic.
If you do wear it, clean, breathable underwear can feel more comfortable overnight. Otherwise, sleep in whatever makes you feel at ease.
