“In the spring, when we lose one hour of sleep, we see a subsequent 24% increase in heart attacks. In the fall, when we gain an hour of sleep, we see a 21% decrease in heart attacks. That’s how fragile your body is to even just the smallest changes in your hours of sleep.” – Professor Walker
Research has also shown that the sleep deprivation people experience – when DST begins in the Spring and ends in the Fall – results in an increase of fatal accidents. More specifically, when people lose an hour of sleep in the Spring, they are driving while tired and are more likely to get into an accident. In the Fall, people tend to take advantage of having an extra hour available to them; it’s not uncommon to stay out later into the night and/or engage in drinking alcohol — both of which can contribute to a greater likelihood of getting into an accident.
*This is one of the many reasons why we are so passionate about helping people take more control of the light in their environment — so that they can also get better sleep at night. Read: This is Your Brain on TrueDark Twilight Glasses.
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.
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.
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
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.
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.
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.
