How to stop getting so hot while sleeping<br>Use air conditioning. The simplest way to keep your room cool while you sleep is to use your air conditioner if you have one. Central air or a portable window unit will both do the trick.
If you get hot while you are sleeping, a portable window unit will help you to sleep.
A portable window unit will only help you to sleep if being hot is the reason you are not sleeping, so the statement may not be correct. The system is assuming that, because being hot can be remedied by a portable window unit, this will always help you to sleep.
