Smartwatches can help track your sleeping patterns


When World Sleep Day was first observed in 2008, it was far from being an Internet sensation. In fact, the day was chosen in keeping with the March equinox, when the Northern Hemisphere tilts towards the sun and marks the beginning of spring with typically longer and sunnier days.

Nine years later, it was Amitabh Bachchan’s iconic tweet that made World Sleep Day trend on Twitter. Since then, every March 17 (this year, it falls on March 18), the Internet is flooded with memes about sleeping (our favourite hobby), and this trend shows no signs of slowing down.


The growing obsession with sleep

The world has never been as obsessed with sleep as it is now, and a growing number of wellness enthusiasts are taking to monitoring sleep data from their wearables like never before. Sleep trackers on your smartwatch typically track your period of inactivity and measure your sleep duration by identifying the points at which you fall asleep and wake up. These wearables can detect interrupted sleep and sense when you’re tossing and turning or waking up during the night.

A good night’s sleep matters

Having a consistent bedtime can ensure that you have a restful sleep. Many studies have emphasised on the alignment of your sleep times to the body’s circadian rhythm or internal clock. This is why you feel more refreshed if you sleep for 7 hours from 11pm to 6am as opposed to sleeping for 9 hours from 2am to 11am.

Sleep tracking demystified

One of the key pieces of tech are accelerometers (small motion sensors in your smartwatch) that measure how much movement you're making while you sleep. Sleep algorithms analyse data from these accelerometers to estimate sleep time and quality. Wearables also use data from heart rate monitors that track sleep stages – REM (Rapid Eye Movement) to deep sleep – by keeping a tab on heart rates. In-built microphones can measure your respiration by tracking snoring, sleep apnea and how frequently you wake up during the night. Most brands have a sleep score (typically out of 100) that rates your sleep.
