Scientists at ETH Zurich, a public research university in Switzerland, recently published the findings of a clinical study involving a headband that enhances deep sleep. This device—part of a project named SleepLoop—can be put on at bedtime and worn through the night. Using a microchip and electrodes, it measures the brain waves that characterise deep sleep and improves them through an auditory (a clicking sound) signal.
Deep sleep is important for the regeneration of brain and memory. It also has a positive influence on the cardiovascular system. While not all of us can get our hands on sophisticated systems like SleepLoop, there are many other gadgets—sleep devices, if you wish—that can help you sleep better.

According to data from sleep solutions company Wakefit’s Great Indian Sleep Scorecard 2022, one in four Indians think they have insomnia. The report says 50% of 18- to 24-year-olds believe their bedroom environment has been affecting the quality of their sleep; 40% in the same group did not have a dedicated sleeping space. These findings are based on an ongoing survey that collected more than 30,000 responses across India between March 2021 and February 2022.
A March survey from the medical device company ResMed, based on a sleep study conducted with over 5,000 people across India, says that only 53% have tried addressing their sleep problems through devices. The study also reveals that Indians take the longest to go to sleep (the average time is around 90 minutes).
If you would like to improve sleep quality, consider factors such as lighting, sound, sleep tracking and comfort. Melatonin levels, for example, are influenced by the light in our immediate environment, Conor Heneghan, lead sleep research scientist at consumer electronics and fitness firm Fitbit, explained in a recent interview with Mint.
