Many people are now noticing that they do not sleep well after using electronic devices late at night. Some have attributed the sleep disturbance to exposure to blue light, since it is stimulating and is known to reduce melatonin levels at night. But that is only one part of the problem.
It is important to understand that wireless radiation and EMF (electromagnetic fields) emitted by these devices are basically light with a frequency that is below that which our eyes can perceive. We know that exposure to EMF can also draw down our melatonin levels, just like exposure to visible light at night. So, it may be helpful to think of wireless and EMF as invisible lights that should be turned off at night before bed, just like we naturally turn off visible lights.
Here are some basic tips for reducing exposure at night:
- As a general rule, keep electronics out of the bedroom: TVs, cordless phones, cell phones and chargers. Corded phones that don't need to be plugged into power outlets are OK.
- Move digital LED (light emitting diode) alarm clocks away from your head. They generate very large magnetic fields. Ideally, move the clock to the other side of the bedroom or replace it with a battery powered analog or LCD clock.
- Unplug reading lights close to your head. Even lights that are not on will generate electric fields and bring electrical noise closer to your head.
- Turn off cordless phone base stations at night. The cordless phone base is the one that has the physical phone line going into it. Unplug the unit or put it on a light timer. The wireless signal from these base stations is constantly on and has a large reach, so turn it off even if it's far from your bedroom.
- Turn off your Wi-Fi at night. You could put the Wi-Fi router's plug on a light timer, or some routers have a software configuration that will allow you to turn it on and off at specific times. You could also use a remote switch to turn the plug and Wi-Fi on only when you need it for a limited duration of time.
These simple steps will help you avoid the most common electronic and EMF (electromagnetic fields) problems that can interfere with your sleep. When you are ready, there are even more steps you can take to reduce your exposure:
