There’s never a guarantee your next hotel room, regardless of swank, won’t have a dicey air-conditioning unit, a noisy neighbor on the other side of the wall or a combination of partiers and sirens outside the window keeping you awake. Sometimes, just the stress of travel logistics and the fact you aren’t in your own bed is enough to keep you wide-awake.

Research published in Current Biology reveals the first night away is often the toughest. Known in clinical terms as the “first-night effect,” the brain reacts to unfamiliar surroundings by staying awake in one hemisphere as a sort of evolutionary “night watch” response and survival mechanism. A travel-sized, packable solution is the new Sound+Sleep MINI ambient sleep therapy machine, featuring patented Adaptive Sound technology and 48 different sound profiles scientifically engineered to encourage deep, restful sleep and enhanced relaxation. It’s available in black and white-silver.

The MINI responds automatically to intrusive environmental noise with sounds that include lapping water, ocean waves, rainfall, rainfall plus wind and thunder, a babbling brook, a stream with birdsong and multiple white, brown and pink ambient noises. You can power it with batteries, the power adapter and cable it comes with or by connecting the cable to your laptop.

If you want to downsize even more, Sound of Sleep also produces the ’LectroFan Micro. This small, pocket-sized device weighs .3 pounds and does double duty by day as a portable wireless Bluetooth speaker. By night, it provides the option of one ocean soundtrack, five fan sounds and four white noise choices. Its USB rechargeable battery can provide up to 16 hours when set to sleep-sound, and up to six hours in Bluetooth mode.
