Running a space heater overnight increases the risk of fire. If the unit is left unattended or placed too close to flammable materials, such as curtains or bedding, it can ignite and lead to a devastating fire.
The heater's plug and cord, combined with some intuitive on/off switches, pose a not-so-obvious electrical hazard to a curious toddler. Most kids learn to back away from heat, but very few would anticipate an electric shock. Many space heaters also come with instructions that warn not to leave them on while you sleep.
Sleeping with the heater ON increases the levels of carbon monoxide in the room above the safe level. The risk of asphyxia (sleep death) is high when using gas heaters. The excessive carbon monoxide in the room chokes the supply of blood to the brain, which can lead to hemorrhage and eventually death.
What is the safest heater to leave on overnight? While it's not recommended to leave any space heater on if you're not monitoring it, oil-filled, radiant space heaters are considered safer than ceramic convection (hot air) types, according to Roberson. Both of these options are safer than open-coil heaters.
Electric heaters of any type are unsafe to leave running overnight because they carry a significant amount of risk. If a space heater falls over or becomes too hot from running for too long of a period of time, that can lead to a fast-moving fire that occurs while you are asleep and cannot act fast enough.

Never leave a space heater unattended. Turn it off when you're leaving a room or going to sleep, and don't let pets or children play too close to a space heater.

It isn't bad to run your heating system on a 24/7 basis if outdoor weather conditions demand indoor warmth.
