What is the Biorhythm?
Biorhythm is short for “biological rhythm”. The term was originally used in the early 1900s. At that time, they attempted to describe cycles of someone's physical and mental well-being that oscillate thoughout the year. Now days, the study biological rhythms falls under the term chronobiology and is based on solid and cutting edge research. The technical term would be “circadian rhythm” but most non-scientists still refer to it as the biorhythm. It refers to the fluctuations in physiological processes that occur over a 24 hour period. It is vitally important for your health and and well-being that these internal clocks stay consistent.
Light & the Biorhythm
The clocks of the body are calibrated by external inputs.
The Central Clock
The master clock is a section of the hypothalamus called the suprachiasmatic nucleus (SCN). There are special receptors in the eye that feed information directly to the SCN. From there, the SCN distributes signals out to the rest of the body through a vast network of nerves. The receptors in the eye are called photosensitive ganglion cells which are sensitive to light. They are super sensitive to blue light in particular. It’s through these sensors that the Central Clock keeps track of the time of day.
There are other clocks that are responsive to other environmental inputs. Things that can affect these clocks are food intake, temperature, and stress. Any one of these alone is not as influential as the Central Clock but they are all important.
Light is a Drug
Light is the single most powerful circadian signal and has profound effects on our biology. Light exposure directly suppresses melatonin production. Which is great in the daytime but extremely problematic at night. Because of this, it is important that our light exposure is rhythmic and stable. Light in the day, dark at night. In modern time our darkness is fragmented and erratic.
Protecting the Biorhythm
Here are a few tips for maintaining a health biorhythm:
Get as much natural light as possible
Crank up the brightness and color temperature as much as you can indoors
Spend time outdoors, nothing beats the natural full spectrum light of our sun
Use low wattage incandescent lights or orange colored LED or CFL lamps
If you need to use nightlights, get red or orange ones
Use task lighting rather than overhead lighting
Use blue light blocking nighttime eyewear
Get yourself some quality blackout curtains
Tape over all the annoying LED lights in your room
Keep your bedroom cool
Maintain a regular bedtime and awake time
BioRhythm SafeTM the New Standard for Nighttime Light Exposure
It is our mission to bring standardization to the industry. New products designed with protecting the biorhythm need a standard to go by.
It is important for all our products emit or filter 100% of light waves below 500nm frequency. We begin to allow some a small amount of light (less than 6%) in the 500 to 540 range. These standards strike a balance between color rendering and melatonin suppression. Our nighttime eyewear blocks 99.8% of light between 450-510nm.
By keeping out light of these disrupting ranges we are creating a virtual darkness. We can see and do things like normal without sending daylight signals to our brains. This allows our bodies to shift easily and naturally into nighttime physiology. The result is rapid sleep onset and deep rejuvenating sleep cycles.
Wearing our blue blocking nighttime eye wear is the most simple and cost effective way to take control of your light exposure.
