The Science of Why You Should Put Foil on a Doorknob When You’re Home Alone

Static Electricity Discharges

The scientific explanation for this phenomenon has to do with static electricity. When you’re walking around your house, your body builds up static electricity. This is especially true if you’re wearing socks or slippers on carpeted floors. When you touch a metal doorknob, that static electricity discharges—and it can discharge so forcefully that it actually unlocks the door!

So how does the foil prevent this from happening? By creating a barrier between your hand and the doorknob, the foil prevents that static electricity from building up in the first place. As a result, your door stays locked and you can rest easy knowing that no one is going to come barging into your house unannounced.

Prevent Electromagnetic fields

The theory behind putting foil on a doorknob is that it will prevent electromagnetic fields from entering the home. These fields are thought to be harmful, and they can also disrupt electrical equipment and cause headaches or dizziness. By wrapping a doorknob in foil, you create a barrier that will block these fields and protect you from their negative effects.

Does It Really Work?
There is no scientific evidence to support the claim that electromagnetic fields are harmful to humans. However, some people believe that they are, and they say that foil does help to reduce the effects of these fields. If you’re concerned about electromagnetic fields, wrapping your doorknob in foil is an easy and inexpensive way to reduce your exposure to them.

For Safety

Foil Prevents Intruders from Opening Doors Silently

One of the biggest dangers of being home alone is that an intruder could break into your house without you knowing. This is especially true if the intruder is experienced and knows how to pick locks or disable alarms. However, if you have foil on all your doorknobs, an intruder won’t be able to open any doors silently. The foil will make a loud noise as it crumples, alerting you to the intruder’s presence and giving you time to escape or call for help.

Foil Makes It More Difficult for Intruders to Enter Your Home

In addition to making noise, foil also makes it physically more difficult for intruders to enter your home. This is because most intruders rely on being able to grip the doorknob in order to turn it and open the door. If the doorknob is covered in foil, it will be much harder for an intruder to get a good grip and turn the knob. As a result, intruders will often give up and move on to an easier target.

Whether or not you believe that electromagnetic fields are harmful, wrapping your doorknob in foil is a quick and easy way to reduce your exposure to them. If you’re looking for an extra layer of protection against these fields, give it a try!
