It may be convenient to leave your TV on constantly, but if it’s an older model, this may cause it to become less functional. BBC highlights that malfunctioning household appliances, like TVs, also caused almost 12,000 fires in Britain in three years, so it’s also for your own safety!

It’s important to power off your vacuum cleaner when it’s not in use, as leaving it running unattended can increase the risk of overheating. It can also lead to motor wear, posing a damage risk as well as a fire hazard if something gets sucked up and blocks the airflow in it.

Finally, electric fans should always be powered off and disconnected when not in use. Continuous operation can accelerate motor and blade wear, potentially shortening the fan’s lifespan. Furthermore, leaving a fan running unattended may increase the risk of fire in case of malfunctions or airflow obstruction. It’s just not wise.
