Both Tisdale and France are light sleepers who find it difficult to snooze external noises and hustle and bustle — that is, until they started using the Snooz Smart White Noise Machine ($100). This white-noise machine has a real fan inside for a calming, soothing sound that doesn't feel manufactured. It has 10 volume settings and lets you adjust the fan tone. The accompanying app lets you create schedules to automatically turn on and off and control the white-noise machine remotely. "You can sleep anywhere because it blocks out pretty much every noise unless there's a massive sound," France explains. It's a core part of Tisdale and her family's nighttime routine as well. "We have one for our daughter as well, but it's hard when you leave to go to a hotel room — you're like, 'Oh my God, I need my white-noise machine,'" she explains.
