How Circadian Rhythms Really Regulate How And When We Sleep

Circadian Fact Friday – How Circadian Rhythms Really Regulate How And When We Sleep
By: Robert Soler, BIOS VP of Human Biological Technologies and Research

How do circadian rhythms really regulate how or when we sleep? This video details how sleep and alertness work together each day (shout out to UCSD’s Bioclock Studio). One thing that isn’t discussed here is that sleep homeostasis is regulated by sleep timing and duration, where circadian drive is primarily regulated by light timing. Because of modern society’s inappropriate delineation of day and night, these two processes become out of sync with each other and confound sleep. BIOS Lighting is designed to bring critical daytime signals, not found in typical LED lighting, into your work or school to make sure these two processes are aligned.

Circadian Fact of the Day: Mammalian Genetic Expression and Circadian Rhythmicity
By: Robert Soler, BIOS VP of Human Biological Technologies and Research

Fourty-three percent of mammalian genetic expression is found to have circadian rhythmicity. Circadian lighting is so much more than just melatonin and productivity, and the light pathway is the key to keeping the master clock in sync. However, interior lighting is sending poor daytime signals, making our master clock’s confused and leading to potential health consequences. BIOS lighting with SkyBlue™ Technology provides critical daytime cues not found in other LED lights, making it ideal for daytime applications such as offices and school.

What’s your chronotype?

Circadian Fact of the Day: Chronotype
By: Robert Soler, BIOS VP of Human Biological Technologies and Research

Chronotype refers to our self-selected preference for sleep and wake time. Age and sex can predict what these preferences are. New data reveals the amount of time you spend outdoors can also impact these preferences. BIOS lighting is designed to bring critical daytime cues into your workplace or school, to help your body feel like it’s been outside more. We do it in a color temperature you actually want to have inside. Learn more about BIOS SkyBlue™ Technology here.

By: Robert Soler, BIOS VP of Human Biological Technologies and Research

Social implications are always the challenge, however, studies show that with the proper lighting the night owl tendencies can go away. Maybe we’re taking the wrong approach by trying to make everyone conform. High amounts of daylight cues in the classroom can help shift these night owls to an earlier time. BIOS lighting technology is designed to bring those critical daytime signals, not found in typical LEDs, into the classroom.

Cortisol Awakening Response – The Reason We Wake Up Around The Same Time Each Day

Circadian Fact of the Day: Cortisol Awakening Response
By: Robert Soler, BIOS VP of Human Biological Technologies and Research

Cortisol Awakening Response (CAR) is a circadian process designed to get us out of our sleep-inertia-grogginess each morning. You may notice it as your ability to wake up without an alarm clock, no matter what time you went to bed. Unfortunately, for some this comes too early, leaving them unable to sleep-in and catch up on sleep lost from a long week. For other it comes too late, leaving them feeling groggy and in search of caffeine. The reason it can come about at the wrong time is due to confusion of our clocks caused by poor daytime cues from indoor lighting. Adding the right daytime signals can help make sure your Cortisol Awakening Response comes at the RIGHT time. BIOS SkyBlue LED Technology is a simple static spectrum solution designed to provide critical daytime signals, not found in legacy LED product, ideal for the office or classroom. For more information on SkyBlue LED Technology, click here.

Trouble falling asleep? This could be why.

Circadian Fact of the Day: Wake Maintenance Zone
By: Robert Soler, BIOS VP of Human Biological Technologies and Research

The reason we have trouble falling asleep at night may have less to do with melatonin suppression and more to do with the circadian process known as the “Wake Maintenance Zone”. It is a pre-electric-lighting survival mechanism designed to help us find safety prior to the onset of darkness. We are more alert and creative at this time. The reason it can come about when we want to be asleep is due to confusion of our clocks caused by poor daytime cues from indoor lighting.
