Wi-Fi has become a big part of our daily lives. It keeps us connected to the internet, powers our smart homes, and lets us stream our favorite shows. But lately, there’s been a lot of talk about turning off Wi-Fi at night. Some people say it’s good for your health, while others think it’s just a waste of time. With all the information out there, it can be hard to know what’s true and what’s not.
That’s why I’ve put together this list of 10 facts and myths about turning off Wi-Fi at night. I’ll break down what science says and what’s just made up.
1. It can save energy
Turning off your Wi-Fi router at night saves electricity. Although routers don’t use a lot of power, every little bit counts. Over time, this can add up to lower energy bills. It’s a small step that can help your wallet and the environment.
2. Wi-Fi causes cancer
There’s no good scientific evidence that Wi-Fi causes cancer. Wi-Fi signals are a type of radio wave that’s too weak to damage our cells. Many studies have looked into this and haven’t found any link. It’s okay to keep your Wi-Fi on without worrying about cancer.
3. It might improve your sleep
Some people say they sleep better with Wi-Fi off. This might be because they’re not tempted to use their phones or tablets in bed. Better sleep can lead to better health and mood. However, it’s the device use, not the Wi-Fi itself, that affects sleep.
4. Wi-Fi makes you sick
Science doesn’t support claims that Wi-Fi causes headaches, nausea, or other symptoms. These symptoms are real, but Wi-Fi does not cause them. They might be due to stress or other factors. If you feel sick, it’s best to talk to a doctor.
5. It can boost your internet speed
Turning off Wi-Fi when you’re not using it can sometimes make your internet faster. This is because fewer devices are competing for the signal. It can be especially helpful if you have a lot of smart home devices. But the difference might be small if you have good internet.

6. Wi-Fi damages plants
Some people think Wi-Fi hurts plants, but this isn’t true. Plants can be affected by very strong electromagnetic fields, but Wi-Fi is much too weak. Your houseplants are safe with your Wi-Fi on. They need water and sunlight more than they need you to turn off your router.
7. It can increase security
Turning off your Wi-Fi at night can make your network a bit more secure. Hackers can’t try to break in when the network is off. However, good passwords and up-to-date software are more important for security. Think of this as an extra step, not the main way to stay safe online.
8. Wi-Fi causes insomnia
Wi-Fi itself doesn’t cause sleep problems. But using devices that connect to Wi-Fi before bed can mess with your sleep. The blue light from screens can make it harder to fall asleep. The real problem is the habit of late-night scrolling, not the Wi-Fi.
9. It can reduce EMF exposure
Turning off Wi-Fi does lower your exposure to electromagnetic fields (EMF). While there’s no proof that this level of EMF is harmful, some people prefer to limit it. If you’re worried about EMF, turning off Wi-Fi at night is an easy way to reduce it. But remember, many other things in your home also produce EMF.
10. Wi-Fi interferes with brain activity
There’s no evidence that Wi-Fi messes with how your brain works. Your brain uses electrical signals, but they’re much stronger than Wi-Fi signals. Wi-Fi can’t change your thoughts or control your mind. Your brain is well protected from the weak signals Wi-Fi uses.
