Yes, as a rule, a fan can be left on all night, as long as the device is in good condition, can rotate freely, and you do not aim the airflow directly at your face. A pedestal fan uses little power, but always follow the manufacturer's manual. Also, be mindful of a dry throat or stiff muscles: in that case, a lower setting or a different position is better.
Is a fan safe at night?
A well-maintained fan is designed for prolonged use, but heat and dust are points of attention. Ensure the cord is not pinched, the fan is stable, and nothing is hanging against the grille, such as curtains or bedding. Clean the device regularly; you can read how that works in How do you clean a fan?. When in doubt, never use a damaged cord or a wobbly base.
What does it cost to run a fan all night?
It’s not much. The Dynter AV25G has a power consumption of 55 W. Running it for eight hours equals 0.44 kWh. At a sample rate of 30 cents per kWh, which is an assumption, that is about 13 cents per night. You can read more about consumption in How many watts does a fan consume per hour?.
| Situation | Power | Consumption per 8 hours | Costs (30 ct/kWh) |
|---|---|---|---|
| Fan 55 W | 55 W | 0.44 kWh | ± € 0.13 |
| Fan 30 W | 30 W | 0.24 kWh | ± € 0.07 |
The best location and setting in the bedroom
Do not aim the fan directly at your bed, but at a slight angle so that the air circulates through the room instead of blowing over your face. An oscillating function distributes the airflow in a wide angle. Start on the lowest setting and only choose a higher setting if you really need to. You can read about what a fan does for your feeling of coolness in Why does air from a fan feel cooling?.
Direct answer: yes, a fan can usually stay on all night, on a low setting, directed at an angle, and with a clean, stable setup. Follow the manual and pay attention to complaints such as a dry throat.

How to sleep better in warm weather?
A fan helps, but combine it with other measures, such as sun blinds during the day and brief ventilation in the evening. All tips can be found in How do you sleep well when it's hot in the bedroom?. For vulnerable people, such as babies and the elderly, extra caution applies. Consult your GP if in doubt; general information can be found at rivm.nl.

Frequently asked questions
Can a fan overheat at night?
Not during normal use, provided the fan is clean and can rotate freely. Dust and a blocked grille increase the risk.
Will I get sick from a fan?
A fan itself does not make you sick, but air directed straight at the body can cause a dry throat or a stiff neck. Aim it at an angle and choose a low setting.
Which setting is best for sleeping?
Usually the lowest. It is quieter and uses less power.
Should I leave the window open?
A window left ajar can help to exhaust warm air. Just pay attention to safety and noise pollution.
Can a fan be in a baby's room?
Ensure the fan is out of reach and the air is not aimed directly at the baby. When in doubt, seek advice from your local health clinic or GP.
