A fan is a sleep essential when summer has turned your bedroom into a sauna but with the Shark FlexBreeze Tablemate Fan, now $129.99 at Amazon , I find falling asleep a breeze — even during the recent heat wave.

Whichever fan you choose, you're in for a cooler night that makes sleeping during summer heatwaves a breeze.
