Is it okay to run a space heater all night?
<|assistant|>
No, it is not okay to run a space heater all night. Running a space heater all night will cause increased energy bills, may be harmful to the environment, and could increase the risk of fire. It is better to set a comfortable temperature and stick with that throughout the night, or use a fan or a blanket instead.
