Is it okay to run a space heater all night?
<|assistant|>
It is generally not recommended to run a space heater all night. Running a space heater for a long time can increase your energy bills and may be unsafe if it is not kept away from combustible materials. You may want to consider alternatives such as keeping your thermostat a little higher at night to avoid running the space heater all night.
