“A few things that I have found improve my sleep are switching all blue lights off before sunset since blue light stops the production of melatonin. I have red lights that turn on before sunset and this has really helped my sleep pattern.”

“These data suggest that in addition to increasing daytime exposure to bright light and reducing evening exposure to blue light, avoiding caffeine later in the day may be important to improve sleep latency.”

“In the evening at your destination, avoid bright light close to bed: by dimming lamps, using blue-light blocking or amber glasses, or engaging in low-stimulation activities, which make it easier to fall asleep in the new night.”

“The bright light exposure activated the prefrontal cortex. Exposure to bright light in the morning is what sets the biological clocks (circadian rhythm) that regulate 15% of the human genome including genes that produce neurotransmitters.”

“###What’s so special about low solar-angle light? Dr. Huberman explains that humans are trichromatic – we have the ability to see blue, red, and green (short, medium, and long wavelength light) and sense differences or contrasts between these colors.”

“A single night of light exposure during sleep impairs glucose metabolism via activation of the "fight-or-flight" response. Light is the primary signal that entrains the body's master clock to set its 24-hour circadian cycle.”

“For example, light and moderate drinkers have better dental hygiene, exercise routines, weight, diet quality, and income than abstainers. When these confounding factors are adequately controlled for, most or all of the protective effects of alcohol on disease risk are abolished.”

“Authors of a new report found that children exposed to a wide range of light intensities experienced melatonin suppression that may decrease sleep quality. Light activates photosensitive cells in the retina that contain a pigment called melanopsin, which is most sensitive to blue light around 480 nanometers in wavelength.”

“Other strategies include reducing light exposure at night (especially blue light from screens) and decreasing stimuli that might keep us awake (like television). An interesting overlap of risk factors between COVID-19 and vitamin D status Dr. Seheult also describes some interesting associations between COVID-19 risks, outcomes, and vitamin D status.”

“02:47:31 - Rhonda’s personal experience with night terrors and Joe’s personal experience with sleep apnea. 02:55:37 - Reducing blue light exposure in the evening can improve natural melatonin production and sleep quality.”
