While the white noise from a fan can help some people sleep, the constant breeze can:
Cause muscle stiffness or cramps from prolonged cooling
Make you too cold later in the night as temperatures drop
And if the fan is loud or wobbly?
That vibration and noise can fragment your sleep cycles.
4. It Can Spread Germs in Shared Rooms

Not ideal during cold and flu season.

Ever woken up with a stiff neck or shoulder pain?
That could be “fan neck” — when cold air blows directly on your body all night, causing:
Muscle tension
Reduced circulation
Trigger points that feel like knots
It’s like sleeping under an AC vent — but without the thermostat control.
✅ Safer & Smarter Alternatives to Sleeping With a Fan
Use a fan to cool the room before bed, then turn it off
Lowers temperature without overnight exposure
