Flickering Lights

Flickering lights are the most common cause of headaches and pains for many people. To some extent, they are inevitable, as they occur due to power fluctuations in the grid. However, if your light bulbs flicker all the time and your headache seems particularly intense or frequent with these lights, they may not be at their intended frequency. Many people will question why do bulbs flicker in the first place and what is causing this problem? This article will answer all these questions, mostly so you will know what to do in the future.

Is Flickering Light Dangerous For Your Health?

Flickering lights can cause many different side effects, such as:

1. Fatigue

Flickering light can cause widespread fatigue in your body. You will feel exhausted after prolonged exposure to them. To avoid this, try to reduce the exposure of these lights by placing a dark cloth over the bulbs.

2. Headaches

Flickering lights can cause headaches related to eye strain or bright lighting, but in some cases, it is caused due to low-frequency flicker. Headaches can be muscular, temporal, or vascular and tend to subside within a few hours.

3. Dizziness

Dizziness is caused due to the flickering light entering your brain through the same pathway it uses to process motion, making you feel like you are moving when you are not. Try to eliminate this source of stress by using dimmer switches and turning up the brightness in your home and at work levels.

4. Sleep Problems

Flickering lights can make it difficult to fall asleep, and they may wake you up during the night. Reducing the amount of light in your bedroom during your evening routine is important, especially in the two hours before bed.

What is Causing My Lights to Flicker?

The following are some common causes of flickering lights:

1. Power Surge

Power surges occur in many households and can be caused by several elements. A power surge is a sudden change in the electrical current that flows to your home. These surges can be caused by damaged power lines or overuse of certain appliances. When these surges occur, the normal frequency of electrical current drops or changes unexpectedly, which causes your lights to flicker.

2. Loose Light Bulb

Loose sockets and poor wiring can cause loose light bulbs. If your light bulb is loose, it can cause many problems, including flickering and dimming lights. If your light bulbs flickers constantly, use a screwdriver to tighten your light bulbs. If that does not work and you still have the problem, consider replacing the socket or hiring an electrician to inspect the wiring in your home.

3. Type Of Light Bulb

Different types of light bulbs have different frequencies. This is because different lamp types contain varying amounts of metal, and when they get hot, the metal inside will expand at a different rate than the glass part of the bulb. The difference in frequency can cause flickering lights. Incandescent bulbs flicker at a higher frequency, while fluorescent bulbs flicker at a lower frequency. If your light bulbs flickers constantly, you may want to consider changing them to see if that solves your problem.

4. Circuit Overload

Circuit overload can directly or indirectly cause your lights to flicker. If your circuit is overloaded, it can cause voltage surges which will cause the lights to flicker and dim. Overloaded circuits can be caused by many different things, such as too many appliances plugged in at one time, extension cords plugged into an outlet, or even water pipes not properly installed in the wall.

5. Loose Wiring

A common reason for flickering lights is loose wiring. This can occur when wires are pulled out of their sockets, or the wires themselves are not tight enough to hold the electricity in. If your lights flickers more often, use a screwdriver to tighten them. If that does not work and you still have the problem, consider hiring an electrician to inspect your circuit.

Ways You Can Fix Flickering Lights By Yourself

There are a few ways you can fix your flickering lights by yourself.

1. Tighten Loose Bulbs

Try to tighten your bulbs as best you can if they flicker constantly. Use a screwdriver to tighten up the light bulbs. In addition, make sure that the sockets themselves are tight and secure. This will prevent the light from moving around in the socket, which can cause it to be loose and, in turn, cause flickering lights.

2. Upgrade Old or Incompatible Switches

If your light bulbs are constantly flickering, consider upgrading to a more modern or compatible switch. The older switches will cause your lights to flicker and dim much more than the newer ones.

3. Replace Unstable Wall Outlets

If your light fixtures are constantly flickering, it is important to ensure the wall outlet you are using is secure and sturdy. Sometimes, the outlet can be accidentally moved into an unstable position, which will cause the current to fluctuate in a way that makes your light fixtures flicker.

4. Try a smart bulb

If your light bulbs are constantly flickering, consider purchasing a smart bulb. Smart bulbs are a newer technology that can sense the frequency of electrical current and adjust accordingly. You can even purchase the fixtures themselves, which allow you to turn your lights on and off with your smartphone or tablet.

5. Don’t Overload Your Circuit

If your light bulbs are constantly flickering, avoid overloading your circuit by unplugging unnecessary appliances or plugging extension cords into the wall properly. This will help prevent voltage surges, which will also prevent flickering lights.

6. Double Check Your Wiring

If your light bulbs are constantly flickering, double-check your wiring. You may want to use a screwdriver to tighten the wiring and plug each wire into its appropriate place. This will make sure that power is efficiently flowing through your entire home.

When to Hire an Electrician to Fix The Flicker

If you do not know how to fix the issue, consider hiring an electrician. An electrician can inspect your entire home and ensure everything is properly wired and up to code. They can also help you pick the right switches for your home if you are having trouble finding them. Another way an electrician can help is by helping you troubleshoot the issue by testing all of your light bulbs, checking for voltage surges, and checking for loose sockets or wires.
