By now, most of us have heard that screen time immediately before bed is a bad idea. According to a study published in the journal Cureus, restricting phone usage before sleep showed positive effects on memory, sleep quality, mood, and the time it took to fall asleep. If our phones are out of the room or turned off when we tuck in for bed, there's a strong chance that many of us would sleep straight through our important commitments the next day. If you've committed to creating a peaceful bedroom for a good night's sleep, a low-tech device like IKEA's Kupong alarm clock will help eliminate the need to have access to your phone throughout the night and into the morning. Coming in at just $1.99, this simple product can be one of the most affordable swaps you can make to improve your sleep quality.
