Method: https://coolsleeppicks.com/how-we-research#our-score Heat builds up under the sheets fast, and a ceiling fan often does not reach it. A bed fan directs airflow between you and the covers, moving warm, damp air away so the space where you sleep feels cooler. This guide compares cooling bed fan designs, from under-cover airflow units to bedside models, and what to weigh for noise, airflow, and placement. ## Picks ### 1.
