What Are The Best Features Of Sleep Trackers?
There are some common features found in every sleep tracker, but some wearable and contactless devices offer more than just the regular sleep time analysis. Let’s take a look at the exciting features some of the best sleep trackers have to offer:
Most sleep trackers offer heart rate and sleep stage analysis, but if you’re looking for more comprehensive data, some advanced sleep trackers use smart listening technology to pick up any breathing irregularities or loud snoring. The advanced sleep tracking system in contactless devices can also assess the temperature, air quality, and brightness level in the bedroom and suggest improvements to help you get better sleep at night.
Some sleep trackers offer smart analytics to give you a better picture of your sleeping pattern and allow you to compare certain metrics---like bedtime, amount of shut-eye, and snoring---over several days, weeks, and even months. Some smart sleep trackers will even overlay these metrics to suggest important changes to your environment for better sleep. Wearable sleep trackers also allow you to track your daily activity level to better understand how your sleeping habits affect your overall health and energy levels.
Whether you prefer a contact-free or a wearable sleep tracker, many of these systems offer ‘silent’ or smart alarms that allow you to specify a time window for waking up the next morning. The device determines when to wake you up based on your total sleep time, using soft vibrations instead of a loud alarm.
Most sleep trackers will allow you to sync your analytics with its own smartphone app through Bluetooth. Wearable gadgets often have a small LED screen that is difficult to read, whereas non-wearable technology has no screen at all.
With a smartphone app, you can conveniently view and control your metrics on your phone whenever you want. Syncing a wearable sleep tracker to your smartphone will also allow you to receive notifications and phone calls directly on the tracker, which is especially useful when you’re away from your phone.
It’s important to check online reviews before buying a wearable sleep tracker that you’ll probably wear all night. Most sleep trackers are lightweight and come in a variety of designs, colors, and sizes to suit different preferences. But sometimes, a sleep tracker might not match your wrist size or have a design flaw that makes it unsuitable to wear at night. Do your research and read about other people’s experiences before making a purchase decision.
Battery life isn’t much of an issue with no-contact sleep trackers, which only work as long as they’re plugged into the wall or a USB port. However, wearable trackers only need to be charged periodically; therefore you must ensure that the one you’re buying boasts a long battery life so that you can get the most out of it even when you don’t have access to a charger or a charging port for several days.
What Are The Different Types Of Sleep Trackers?
There are so many different sleep trackers on the market that boast unique designs and features, but when it comes to their technology, these devices can be categorized as wearable or non-wearable sleep trackers. Here’s everything you need to know about these two categories:
Wearable Sleep Trackers
There are many different types of wearable devices that work as fitness and sleep trackers. These gadgets are commonly worn around the wrist or even fingers that track your activity throughout the day and even when you’re asleep.
Wrist Trackers and Smartwatches
Smartwatches are the most popular type of wearable sleep trackers which employ special sensors for monitoring the heart rate and activity level. Wrist trackers can be paired with your smartphone through their own app, allowing you to track your progress and identify any factors that might cause disturbances in your sleep.
If you’re looking for something that’s less obtrusive with similar features as a smartwatch, then a sleep tracker ring might be a good option. This comprehensive device doubles as a fitness tracker that monitors your body temperature, heart rate, activity level, and key sleep metrics. Like smartwatches, sleep tracker rings can also be synced to a smartphone app for a more in-depth analysis of your nocturnal wellbeing and overall health.
Non-Wearable Sleep Trackers
Some people want to monitor their sleep activity with technology that isn’t as intrusive as a smartwatch or other types of wearable sleep trackers. If you prefer not to have any skin contact with your sleep tracker, then you might want to look into non-wearable options that can be installed under the mattress and sometimes even come built into the bedding. These sleep trackers use sensors to monitor biometrics like movement frequency, sleep stage cycle, heart rate, and much more. Since these sleep trackers don’t have an LCD screen, they rely on smartphone apps to convey analytics and share helpful tips to improve your sleep quality.
How Much Do Sleep Trackers Cost?
Sleep trackers can cost anywhere between $50 and $300, depending on the brand and the model. At a minimum, a sleep tracker is able to monitor your bedtime routine and track how much you sleep every night. Sleep trackers on the more affordable end of the spectrum lack a display but can be connected to an app that helps you monitor key metrics.
If you’re looking for something more sophisticated, you might want to spend a little more and invest in a gadget that can double as a fitness tracker with a built-in GPS, LED screen, heart-rate monitor and so much more. These sleep trackers are often geared towards the health-minded folks who love staying active. But you don’t need an expensive gadget if all you need to monitor is your sleep. There is are plenty of non-wearable sleep trackers that can be slipped under the mattress and aren’t too intrusive or expensive.
