The Best (and Worst) Bedroom Tech for Sleep in 2025
From smart mattresses to sleep robots, technology promises better sleep. But most gadgets are unnecessary. Here's what actually works.
Tech That Actually Helps
White Noise Machines
Genuinely useful for masking inconsistent sounds. Better than apps because they don't emit blue light. Look for ones with natural sound options.
Smart Lighting
Bulbs that automatically dim and warm in the evening. Sunrise simulation alarm clocks for gentler waking. Worth the investment.
Temperature Control
Eight Sleep, ChiliPad - mattress cooling systems. Expensive but effective for hot sleepers and couples with different temperature preferences.
Tech to Remove From Bedroom
- TV (if you can't resist watching)
- Work laptop
- Phone (or at minimum, face-down and silent)
- Bright alarm clocks
The Minimum Effective Tech Setup
All you really need: blackout curtains, white noise machine, and a simple sunrise alarm clock. Everything else is optional optimization.

Does technology in the bedroom hurt sleep?
Yes, primarily through two mechanisms. Blue-spectrum light from screens (phones, TVs, tablets) suppresses melatonin production and delays sleep onset by 30-90 minutes when used in the 90 minutes before bed. Second, notifications and the psychological pull of smartphones increase cognitive arousal and sleep anxiety (checking the time, worrying about messages). Studies show that phone charging outside the bedroom produces significant improvement in sleep onset latency and subjective sleep quality.
Should you have a TV in the bedroom?
Sleep medicine guidelines recommend against televisions in bedrooms. Active TV watching delays sleep onset through light exposure and cognitive arousal. Passive background TV appears to fragment sleep through audio stimulation during sleep transitions. People who fall asleep to TV reliably wake more frequently during the night as audio changes during sleep cycle transitions. For people who use TV to wind down, transitioning to audio (podcasts, white noise) in the bedroom achieves the same effect with less sleep disruption.
Does room temperature monitoring technology help sleep?
Smart thermostats and temperature monitoring devices that maintain bedroom temperature at 65-68°F throughout the night are among the most effective sleep technologies because temperature is a genuine, strong sleep regulator. Active cooling mattress pads (water-circulating systems) take this a step further by cooling the sleep surface directly. For hot sleepers, these technologies produce measurable improvements in slow-wave sleep and nighttime awakening frequency.
Do sleep tracking devices improve sleep?
Tracking reveals patterns and motivates behavior change for most users. However, orthosomnia — sleep anxiety driven by excessive focus on sleep tracker data — is a documented phenomenon where obsessive checking of sleep scores worsens sleep quality. Best practice: check trends weekly rather than nightly, focus on behavioral correlations rather than stage percentages, and treat consumer tracker data as rough estimates (70-80% accurate for sleep stages compared to polysomnography) rather than diagnostic data.
