In today’s connected world, most people sleep with their phone nearby and WiFi routers running. This habit might feel normal, but research suggests it may harm your health. Experts now recommend turning off your WiFi at night and placing your phone in another room on airplane mode. This practice may help improve sleep, lower your exposure to radiation, and reduce stress. The following sections explain why this simple change can make a big difference.
Reducing Exposure to Electromagnetic Fields (EMFs)
WiFi signals emit low-level electromagnetic radiation. While this radiation is considered non-ionizing, there are long-term concerns. The World Health Organization classifies EMFs as possibly carcinogenic to humans. This means that although there is no confirmed cancer link, some studies raise red flags. At night, your body repairs itself during sleep. Reducing exposure to EMFs during this time may protect your health. Disconnecting WiFi and setting your phone to airplane mode can reduce your total radiation load overnight.

Improved Sleep Quality Without WiFi Interference
Melatonin regulates your sleep cycle. Exposure to EMFs from WiFi signals may lower melatonin levels. A study in the Journal of Environmental Health Science found that wireless radiation might disrupt melatonin production and disturb sleep. When WiFi remains on and your phone stays active, these signals may interfere with deep sleep. By turning off the router and removing your phone from the room, your body can better maintain its natural rhythm. As a result, you may fall asleep faster and sleep more soundly.
Limiting Blue Light and Digital Distraction
Phones are not only WiFi sources but also emit blue light. This light interferes with melatonin, which delays sleep. Notifications and late-night scrolling also stimulate your brain, making it harder to relax. Putting your phone in airplane mode and leaving it outside your room reduces these distractions. You’ll stop the endless urge to check messages or scroll through social media. Over time, this habit supports better sleep hygiene and mental relaxation.
