As millions struggle with restless nights, sleep experts say the answer may be sitting right in your hand. While smartphones are often blamed for keeping people awake, new features designed to reduce screen disruption are turning these devices into unexpected sleep allies. From blue light filters to digital wind-down routines, these tools are helping users create healthier nighttime habits.
According to research at the National Library of Medicine, exposure to blue light at bedtime suppresses melatonin secretion, postponing the onset of sleep and interrupting the sleep process. Some smartphone manufacturers have introduced night-mode functions, which have been claimed to aid in improving sleep quality, like Apple’s iPhone Night Shift feature, which purports to reduce short-wavelength light emissions and improve sleep
The challenge is that most people don’t know how to use their devices in a way that supports sleep instead of sabotaging it. Malik Karman, certified sleep coach at Eachnight.com, has been helping people reframe their relationship with technology and rest. He says that with the right settings, smartphones can shift from sleep disruptors to sleep enhancers.
“Phones have become part of our lives, and they’re not going anywhere,” says Karman. “The key is to make them work for your sleep rather than against it. That means using their built-in tools intentionally, not mindlessly scrolling before bed.”
In the last few years, both Apple and Android have rolled out advanced sleep features, including:
- Blue light reduction modes that filter stimulating wavelengths in the evening
- Bedtime reminders to cue a wind-down routine
- White noise and soundscapes for a consistent sleep environment
- Sleep tracking tools that analyze patterns and suggest improvements
These updates reflect a shift in how technology companies approach wellness, giving consumers the ability to build better sleep habits without buying new devices.
Here are five ways to make your phone a sleep ally:
- Turn on night mode at least two hours before bed to reduce blue-light exposure.
- Set a recurring bedtime reminder to create a consistent wind-down schedule.
- Use a white noise or nature sound app instead of streaming video before bed.
- Keep the phone on Do Not Disturb mode to avoid late-night notifications.
- Charge your phone away from your bed to resist the temptation to scroll.
“Many people think the only way to improve sleep is to ban phones from the bedroom, but that’s unrealistic for everyone,” says Karman. “Having it nearby is part of daily life for shift workers, parents, or people who use their phone as an alarm clock. The goal is not to remove the device but to manage how and when it’s used in those crucial pre-sleep hours.”
