ELECTRONICS IN THE BEDROOM: THE INVISIBLE IMPACT ON YOUR SLEEP
I believe that sleep is one of the most powerful pillars of functional health.
But what happens when your own bedroom — the place meant for rest — becomes a source of stimulation?
Phones, tablets, Wi-Fi routers, TVs, and baby monitors are now part of almost everyone’s night routine.
Science is starting to show that this constant exposure may be quietly affecting something essential: your sleep quality.
What Recent Studies Show:
Screen use before bed — JAMA Network Open, 2025
A study with 122,000 adults found that people who used screens before sleeping got 7.6 minutes less sleep each night and were 33% more likely to report poor sleep quality.
Even short exposure delayed sleep onset, especially in those who already go to bed late.
Wi-Fi exposure in the bedroom — Frontiers in Public Health, 2024
In a double-blind trial, volunteers were exposed to Wi-Fi radiation during sleep.
The result: changes in brainwave patterns (EEG) and more sleep disturbances.
Although this was a small study, it suggests that even normal home-level Wi-Fi signals may influence sleep structure.
Teen screen time in bed — JAMA Network Open, 2024
For every 10 extra minutes of screen use in bed, total sleep time dropped by 3 minutes.
Interactive content like games or videos had an even stronger effect, keeping the brain alert long after the lights were off.
Sleep is not just rest — it’s the body’s healing and regulation time.
During deep sleep:
• The body repairs tissues and balances hormones,
• The brain clears toxins and stores memories,
• The immune system recharges.
Nighttime exposure to blue light and radio frequency (RF) waves interfere with these processes by:
• Suppressing melatonin,
• Raising nighttime cortisol,
• Activating the sympathetic nervous system, which keeps you alert instead of calm.
Simple Strategies for Better Sleep
- Turn off Wi-Fi and electronics at least 1 hour before bed.
- Keep your phone out of the bedroom (or use airplane mode).
- Avoid TV or scrolling in bed — use your bed only for rest and connection.
- Try reading a paper book or a short offline meditation.
- Keep your bedroom dark, cool, and quiet.
Sleeping well is an important step to living with more energy, clarity, and balance.
