Survey Report, released by Royal Philips ahead of World Sleep Day, since the start of the pandemic, Indian adults experienced new sleep challenges such as difficulty in falling asleep (37 per cent), difficulty in staying asleep (27 per cent ), and waking up during the night (39 per cent). As we continue to grapple with changing slumber patterns, the fitness trackers’ industry has been growing, with more and more wrists, fingers and homes sporting bands, rings and wireless devices that track parameters ranging from steps to sleep.
Unlike a sleep study in a hospital, which can consume considerable time and money, these devices are accessible, and considered fashionable. But what data do they offer? Ali Rizvi, director, Garmin India that manufactures wearable trackers, shares that they help to identify a sleeping pattern. “They provide an in-depth analysis of how one is sleeping, the duration, quality, and a breakdown of their light, deep and REM [Rapid Eye Movement; a sleep stage] stages,” he claims, adding that these trackers help to manage one’s sleep according to their lifestyle. Gaurav Parchani, co-founder and CTO, Dozee, which produces thin sensor sheets that can be placed below mattresses, says as the product doesn’t require participation post installation, it’s handy for senior citizens. “Apart from monitoring heart and respiratory rates at night, we also document heart rate variability — an important parameter of your autonomic nervous system,” he says.
