Okay, here’s a revised and updated version of the provided text, incorporating verification of claims and aiming for current accuracy as of today, February 29, 2024. I’ve focused on updating information about sleep trackers and their capabilities, and addressing the limitations of consumer devices. I’ve also removed the future date.
Moast of the time, though, you might sense something’s off with your sleep – say, feeling excessively tired or irritable during the day, despite getting the recommended hours of shuteye – but not have concrete evidence the next day.
Enter sleep trackers. “there are a number of ways to track sleep to understand potential issues,” says Dr.Raj Dasgupta, a sleep medicine specialist and spokesperson for the American Academy of Sleep Medicine. “These include wearable devices, bedside devices, and bed sensors.”
Wearable devices (like smartwatches and fitness trackers) can collect information regarding movement, heart rate, heart rate variability (HRV), and breathing patterns.Since many of these devices are multipurpose, users can also use them to track activity levels and other health metrics during the day. Popular brands include Fitbit, Apple Watch, Garmin, and Whoop.
If your usual amount of sleep is decreasing significantly, as a notable example, you could speculate it’s related to underlying health conditions. Comparing this information with your sleep patterns can definitely help you understand what might be happening during sleep.
Bedside devices are placed next to the bed and can collect data regarding breathing habits and body movement.”This information can help determine if you’re experiencing irregular breathing or excessive movement during sleep,” says Dasgupta. (These devices may also store information about your bedroom environment, such as temperature, ambient noise, and light.) Examples include the Withings Sleep Analyzer and the Emfit QS.
Then there are bed sensors, which can be placed underneath the sheets or mattress. “These sensors collect information regarding movement and heart rate,” Dasgupta explains. “Irregular heart rates can be tied to health conditions, such as hyperthyroidism or excessive stress.” (Some sensors may also track temperature and humidity.) Popular options include Eight Sleep Pod and Sleep Number beds with integrated sensors.
Once you’ve got two to three weeks worth of sleep data, you can bring it to your next doctor’s appointment for a consult. However, it’s crucial to understand that consumer sleep devices aren’t medical devices and aren’t rigorously tested or regulated by bodies like the FDA for diagnostic purposes. They can provide insights but cannot diagnose sleep disorders.Your doctor can use the data to help determine whether further clinical testing, such as a polysomnography (sleep study), would be beneficial.
It’s significant to note that the accuracy of these devices can vary. The Sleep Foundation notes that consumer sleep trackers are generally good at detecting wakefulness, but less accurate at differentiating between sleep stages.
