Sleeping with a fan can be both good and bad, depending on your needs and sensitivities. It improves air circulation, helping you stay cool and comfortable. It creates white noise, which can aid sleep by blocking out background sounds. But, it may dry out your skin, eyes, or nasal passages. Can trigger allergies if it blows dust or pollen around the room. Tip: Keep the fan clean and at a safe distance for the best balance.
