Sleep Tight: Technology That Might Help You Get Your Rest

Good sleep is the foundation of good health. But when you can’t fall asleep or can’t stay asleep, what else can you do?

Enter sleep technology.

Before you invest in the latest devices, consult your physician to rule out medical causes for your sleep challenges. And make sure you’re comfortable with how these products collect and store your health data. More on that shortly.

Smart mattresses and bedding

Mattresses have continued their evolution from providing passive comfort to delivering AI-powered sleep optimization. Embedded sensors monitor your sleep habits — heart and breathing rates plus movement — and, based on the data they collect, adjust mattress firmness, temperature and even incline in real time to improve sleep quality.

This data is logged and synced to a companion app, where it becomes part of your long-term sleep history. You can view daily summaries and weekly or monthly trends in sleep duration, sleep-stage breakdown, heart-rate variability and respiratory rate. Depending on the system, your smart mattress can even model your personal baseline and alert you to changes in health metrics such as resting heart rate or breathing patterns.

Smart mattresses are also poised to address one of sleep’s greatest challenges: temperature. Personalized sleep climates — whether water-cooled or powered through zoned climate-control technology — are now available for consumers for whom temperature (theirs or a partner’s) is a major factor in restful sleep. For women navigating menopause and its sleep-disruptive hot flashes, this type of technology can make a meaningful difference.

Wearables and sleep-enhancing tools: Headbands and earbuds

Inspired by neuroscience, new headbands and earbuds aim to optimize brainwave activity for better sleep. One device incorporates electroencephalogram sensors and targeted acoustic stimulation into a headband designed to suppress wakefulness and speed the onset of sleep. Another headband provides gentle electrical pulses based on EEG patterns, which is thought to increase sleep duration. A new-to-market sleep mask combines brain monitoring, light reduction, a sunrise alarm and guided audio for relaxation for a more complete sleep-enhancing experience.

Next-generation wearables are also migrating to your ears. Earbuds now monitor your brainwaves and deliver pink noise to deepen sleep. You’ve heard pink noise before — think waves on a beach, rustling leaves or falling rain. Pink noise includes all sounds audible to the human ear but amplifies lower frequencies and softens higher ones. White noise, which some manufacturers still use, shares all sound frequencies at the same intensity, which can be annoying or unpleasant for some people.

Traditional trackers like rings and watches remain relevant but are increasingly advanced, offering insights into sleep stages, heart rate, breathing and sleep apnea risk. Some new rings even generate personalized soundscapes based on real-time biometric data to help you fall asleep more quickly.

Pajamas, pillows and masks incorporate technology, too

Textiles — and the garments and pillows made from them — are getting smarter too. A British manufacturer has incorporated washable fabric sensors that detect breathing, snoring and sleep apnea states with, according to the company, 98.6% accuracy.Broader advances in e-textiles hint at fabrics capable of wireless charging and wireless readouts, promising a future in which entire garments are data-smart and battery-free. Even the pillow is evolving. Some models track your breathing patterns and inflate to realign your head during snoring — a form of silent anti-snore technology.

Efficacy and future trends

While early studies on headbands, mattresses and bedding systems show promise, true long-term efficacy is still to be determined. Even if you opt for one of these new tools, core sleep- hygiene habits still apply: keep your bedroom dark and cool, maintain consistent sleep and wake times and avoid screens for at least 30 minutes before bed.

As sleep-monitoring technologies become mainstream, manufacturers may seek approval for their products as medical devices. It’s also possible that in the future, certain products could qualify for insurance, HSA or FSA reimbursement. As adoption grows, look for increasing synergy among product types, making sleep tracking more comprehensive.

The fine print

Many of these products may sound like foolproof sleep solutions, but they are not medical devices; they are intended for at-home wellness use. The data they collect is stored in the accompanying app or cloud, like other wearable technology. Before you invest in the latest sleep technology, make sure you’re comfortable with what these products do and understand the manufacturer’s privacy policy.
