If you want to be cool like the other side of the pillow, you may want to consider investing in this smart pillow temperature system on Kickstarter. Moona regulates the temperature of your pillow to ensure it always feels cool and you can get a better sleep. Described as "the first smart product improving sleep by regulating pillow temperature," Moona will help you fall asleep faster, sleep deeper and wake up in the morning naturally.
The smart sleep system consists of four key components -- cooling water circulation, a memory foam pad that goes into your pillow case, sleep-tracking sensors and a temperature-controlling device. The sleep aid is ideal for fighting jetlag and taking refreshing naps. It also syncs to an accompanying app that analyzes your sleep and bedroom environment, offers sleep tips and more.
