The HoMedics White Noise Machine features five sounds found in and inspired by nature, including ocean, thunder, rain, brook, and summer night. Of course, it also has a white noise sound, which the brand recommends for relaxing. All of the sounds have their own button on the machine to easily select your favorites. Plus, the device has a volume knob and an automatic shut-off timer for 15, 30, and 60 minutes. Even better, the white noise machine is lightweight and portable. So you can use it throughout your home, whether you’re unwinding with the white noise in your living room or falling asleep to the sound of rain in your bedroom. And if you have an even harder time falling asleep when you’re away from home, you can take it with you when you travel. To buy: $20; amazon.com “I suffer from insomnia and this has made an incredible difference in the amount of time it takes me to fall asleep (it was about an hour, and after a week of use, I’m down to about 20 minutes),” one customer wrote. “I also don’t wake up as many times during the night. I love how the volume is adjustable and how the machine offers more than just white noise.” Others rave that it’s helped their children fall asleep. “This is a great device!” one wrote. “I bought the first one for my kids’ bedroom and it worked like magic. They started to sleep much better and faster. Then when we moved our oldest to her own room, I purchased a second one because she loves the sounds.”
