Why using a fan at night can disrupt your sleep

People who sleep soundly often spark envy in those who rarely get a good night’s rest. If you want to wake up refreshed and ready to tackle the day, there’s a simple way to improve your sleep.

Sleep is vital for both body and mind. It’s not just about hours in bed — quality matters too. Experts recommend seven to nine hours nightly to stay sharp and healthy. Poor sleep raises the risk of cardiovascular disease, diabetes, and depression, and it weakens immunity.

Temperature plays a key role in sleep quality. Too warm or too cold can disturb your rest. The body naturally cools before sleep, so a cooler room — ideally 60–67°F (15–19°C) — supports deep sleep and melatonin release. Too much heat or cold can keep you tossing and turning.
