5 Easy Ways to Stop Junk Light at Home


When the day is done and you’re starting to feel like you badly need to rest, now’s when you’re hoping for a good night’s sleep. But in this day and age, it’s surprisingly hard to fall asleep as soon as your head hits the pillow. And we have junk light to thank for that.

The main culprit of problems like insomnia and poor sleep quality is junk light: man-made light with blue and green hues that tells your body it’s a different time of day than it actually is.

And junk light is everywhere around us today: we stare at the TV or smartphone screen while in bed, there’s street light coming through the windows, and of course, there are bright bulbs in our bathrooms that shake us awake when we want to be winding down.

So what can you do to stop junk light at your home, and make sure you’re getting the sleep you need?


Start from the bedroom

If you want to stop junk light at your home, you need to sleep in complete darkness. This means you’ll have to stop all external light from leaking into your room.

There are a few easy ways to do that:

Use blackout curtains to stop junk light

Blackout curtains are great for stopping street light or other external light from seeping into your bedroom. If you’ve got external light coming in from the rest of the house, you can close the door, and put a rolled up towel or pillow at its base.

Digital clocks and smoke detector lights

You may have light-proofed your bedroom from all outside influences, but you should pay attention to other light sources within the room. Usually, these are smoke detectors and alarm clocks. Since you can’t shut a smoke detector off, you can cover the space where the light is.

If you can avoid sleeping with an alarm clock, that’s the ideal solution. However, if you can’t, get an alarm clock that has red numbers and that’s manually dimmable.

That way, you can keep it dimmed to avoid bright light, and you’ll be less sensitive to red numbers than you will be to blue or green.


Use a lamp

Similarly, if you have a lamp in your room, use a red bulb instead of a white one. It sounds fancy, but you can get a red bulb at bigger hardware stores, and it goes a long way towards stopping junk light and helping you sleep like a baby.


Stop junk light in your bathroom

Even though the bathroom is not as crucial as the bedroom is when it comes to getting good rest, it is the place where you take a shower and brush your teeth before bed. It’s important to keep junk light in check so your internal clock can sense that it’s bedtime.

You can try a red bulb in the bathroom. This can be a red bulb in one of your light sockets, which you’ll use at night.

If you only have one light in your bathroom, make sure it’s a halogen or incandescent. There are options to block blue and green spectrum lights (the ones that are impairing your sleep) by using TrueDark Twilight glasses as you get ready for bed.


Kitchen and living area

Even beyond famous junk light emitters like TV and computers, you’d be surprised at how many little bright lights there are on various appliances. If you want to check, just turn off all the lights and see what glows.

Most lights (microwave clock, oven, coffee maker) and bright blue or green, and those are the worst junk lights you’ll find in your living area. They’re not bad during the day, but you don’t want them shining into your eyes while you’re getting ready to hit the hay.

Even if you don’t notice it, your eyes are taking in that light – and your body is telling your brain it’s daytime, and that you should put the PJs away.

The ideal solution is either to have appliances with red lights or block them out with solid tape.

Since you most likely want to be able to see your microwave clock or other appliance settings, try using TrueDark Dots. They’re stickers that include black block-out and red transparent stickers which will adjust the light your appliances broadcast.

TrueDark Shields are a larger form of the TrueDark Dots, and they can be cut to fit large shapes. They’re designed to work with fluorescent lights and larger digital displays.

If you’ve got fluorescent bulbs in your kitchen, you can use TrueDark Shields and make sure the artificial light isn’t impairing your circadian rhythm.


Bonus junk light tip

If you want to stop junk light throughout your house, change all of your bulbs.

Get rid of all fluorescent light bulbs, including the “CFLs,” the little pigtail bulbs, and other bulbs that say fluorescent or CFL on the packaging. If you have LED lights, avoid “bright white.”

Make sure you read labels before you buy bulbs, and choose halogen or incandescent since they have a lower blue spectrum and don’t have a great blue junk light risk.


Stop junk light at your home

These changes are simple and easy, and you don’t even have to call your electrician. Just switch bulbs and opt for artificial light-blocking solutions like TrueDark products.

If you do want to tackle a more complex junk light project, an electrician can install dimmer switches throughout your house.

Then, as nighttime approaches, just dim your lights to mimic the sun going down. That’ll encourage your body to start preparing for sleep, ensuring that you won’t have any trouble.

And if you really can’t stay away from Instagram and reading the news before bed, try TrueDark Twilight glasses. They’ll block out the artificial light, get your body ready for sleep, and you won’t even have to give up reading the latest updates from your friends.

Junk Light, Disrupted Sleep, and Your Health

Exposure melatonin disrupting junk light can have have effects on many aspects of your health

Weight Gain

Red light and darkness move leptin and ghrelin into patterns that are (context dependent) associated with less hunger, while blue light does the opposite and can move both into patterns associated with more hunger.

Anxiety/Depression & Depression

Increase in cortisol, the stress hormone, due to circadian disruption. Memory recall is impaired with consistent sleep deprivation and may leave you distracted and not performing your absolute best.

Sleep cycle disruption

Junk light exposure when traveling can disrupt your circadian rhythm. Long-term exposure to light at night which accompanies shift work is listed as a probable carcinogen by the World Health Organization. Light at night has shown to be highly associated with significantly the risk of hormone specific such as cancers of the breast and prostate.


The flickering wavelength of light associated with LEDs and compact fluorescent lights emit blue light that inhibits melatonin production but also create a unique glare that impacts your retina causing eye strain, headaches, and physical and mental fatigue.

The Importance of Melanopsin Cells

The Key to Better Sleep

The melanopsin cells detect blue light it tells your brain that it is “daytime” and less melatonin is produced.

Harness Your Biology to Fight Junk Light

Your body requires some blue light at the right time of day and from the right sources. That’s why we created TrueDark® Sleep Technology that gives you 24-protection from junk light day and night.

Use TrueDark® Twilights When You’re Ready for Sleep

Stop Junk Light with patented TrueDark® Twilight technology that frees your hormones and neurotransmitters to do their best work.

When the sun goes down, blue light isn’t the only junk light that can disrupt our sleep cycle and more than blue blockers are needed. Patented TrueDark® Twilight is the first and only solution that is designed to work with melanopsin, a protein in your eyes responsible for absorbing light and sending sleep/wake signals to your brain. Without melanopsin, melatonin can’t be accessed.

When you wear your Twilights for as little as 30 min before bed you prevent your melanopsin from detecting the wrong wavelengths of light at the wrong time of day. This supports  your circadian rhythm and helps you fall asleep faster and get more restorative and restful sleep.

TrueDark® Daywalkers for Your Waking Hours

The highly advanced lenses in TrueDark® Daywalkers operate on a more advanced level than traditional blue blockers.

Blue light emitted from the sun helps regulate our sleep/wake cycle. However, in today’s world, we’re exposed to an overabundance of blue light, or junk light from artificial light. This includes hours spent in front of  TVs, phones, and computers. It also includes time spent in artificial man made light with LEDs and fluorescent lights. Even if we’re simply reading a book, we’re doing that in artificial light which emit dramatically more blue light than the sun. That overexposure to junk light during the day has a dramatic impact on our neurotransmitters and hormones that are responsible for quality sleep.
