You may initially buy these new activity trackers to learn about how many calories you burn in a day, but keep them on at night and you’ll learn lots of information about how you’re sleeping.
Wearable activity trackers aren’t going anywhere anytime soon. And for people who want to learn more about their sleep habits, this is a good thing. That’s because many of the newest activity trackers, like the four below, double as sleep monitors—just wear them on your wrist through the night to get details about the quality and duration of your sleep.
Fitbit Charge HR: The latest offering from Fitbit features a heart rate monitor that tracks your pulse through a wrist sensor. It automatically can tell when you’re asleep based on your movement and heart rate and will monitor how much time you spend tossing and turning, as well as other statistics and trends. Set its alarm to go off in the morning and it will vibrate silently to rouse you. This is especially helpful if you have a partner who needs to wake up later than you, because your alarm won't disturb him or her. ($149.95)
Misfit Shine: This doesn’t just measure total duration of sleep, but also light and deep sleep. And it has a smart alarm feature: You are woken up when you are in a light sleep stage, so you'll feel less groggy when you're roused. No need to set it to a sleep mode—it detects that automatically. The best part is how sleek and pretty the Shine is. Instead of looking tech-y, it is a sophisticated, elegant, silver circle on a band. ($99.99)
Withings Pulse Ox: This watch monitors whether you’re in light or heavy sleep by tracking your movement. Launch the sleep cycle analysis before you drift off. Then, in the morning, check the smart phone app to get graphs showing the cycles and quality of your sleep throughout the night. In addition to tracking steps and calories burned, the device also monitors your heart rate and blood oxygen level. ($119.95)
Jawbone UP3: The newest wrist-worn activity tracker from Jawbone doesn’t just tell you how long you sleep for, it also tracks your sleep stages (REM, light, and deep sleep). It does this through four sensors that monitor heart rate, respiration rate, body temperature, and movement levels. It also comes equipped with something called a Smart Alarm, which will wake you up to a gentle vibration. You can set it to go off at a specific time or give it a range (10 to 30 minutes) and it will go off when you are in a light sleep stage. ($179.99)
