4. You Wake Up Tired Despite Sleeping Enough Hours

If you sleep for seven or eight hours but still wake up feeling unrested, the fan may be subtly disrupting your sleep cycle. While the noise and airflow can feel comforting at first, they may prevent your body from reaching deeper, more restorative stages of sleep.
