Is it normal to sweat under a blanket?
Yep.Totally normal
Yes—sweating under a blanket is normal, especially if your room is warm or your bedding traps heat. If you’re repeatedly waking up drenched despite a cool room, it’s worth checking with a healthcare professional.
A blanket holds in body heat, and some fabrics and thick layers can make you warmer than you realize. It’s common to sweat a bit while sleeping, particularly if you run warm or the room is stuffy.
Try lighter bedding or breathable sleepwear if it’s bothering you. If you’re regularly waking up soaked for no obvious reason, consider getting it checked out.
