The Science of Sleephacking

Recent studies have shown that over-exposure to artificial light at the wrong time of day can have negative effects on your sleep and, in turn, your mental and physical performance.

Approaching Your Health in a Holistic Approach

Overexposure to junk light is only half the picture to sleep health, new research shows that there is a second, more dominant and important system that is responsible for setting your circadian rhythm, sleep patterns and hormones.

Your Eyes: The Messenger to the Brain

Our circadian rhythm dictates our sleep/ wake cycle which begins when the sun comes up, sending a full spectrum of light wavelengths to our eyes who in turn sends signals to our brain to let it know if it’s getting lighter or darker outside. Blue, green and violet light are what our eyes are most sensitive to and what our brains use to regulate our sleep/wake cycle.

When Our Eyes Detect More Blue Light

Our brain to starts our “wake” phase, suppressing melatonin and signals the body to:

• Increase hunger hormone Leptin
• Increase body temperature
• Raise blood pressure
• Increase urine output

Junk Light: The Dark Side of Blue Light

While we get natural and necessary levels of blue light from the sun, artificial light sources bombard us high levels of blue light day and night. This overexposure to blue light, what we term junk light, disrupts our circadian rhythm and depresses our melatonin production, the body’s main sleep hormone.

When Our Eyes Detect Less Blue Light

Our brain to starts our “sleep” phase, increasing melatonin and signals the body to:

• Decrease hunger hormone Leptin
• Decrease body temperature
• Lower blood pressure
• Decrease urine output

Junk Light, Disrupted Sleep, and Your Health

Exposure to disrupting junk light can have have effects on many aspects of your health and sleep!

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.

Headaches/Vision

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.

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.

The Importance of Melanopsin Cells

The Key to Better Sleep

Detects blue light

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

Sending signals to your brain

The signals to your brain to alert brightness and for the brain to increase or suppress the sleep hormone, melatonin.

Light Source

Melanopsin cells can’t differentiate the blue light that occurs naturally form the sun from the junk light emitted from your computer monitor.

Start Optimizing Your Life

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.

Restful Sleep

Synchronizes your circadian rhythm for better sleep

Decrease Weight Gain

Leptin is a master hormone and signals to our brains how much fat storage we have.

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® DayLights for Your Waking Hours

The highly advanced lenses in TrueDark® DayLights 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.
