Become a Founding Member and join the circadian health revolution! We have opened a limited cohort waitlist for the MiEye! Join here: circadianhealthinnovations.c…

We've got two hospitals in London moving their ICU services outside!
That's right - London, England.
We also review a sensor called the MiEye.

CIRCADIAN DISRUPTION FROM HOME LIGHTING VERSUS NATURAL SUNSET
I had the pleasure of sitting down with Professor Sean Cain, PhD, (@circadian247) a Harvard Medical School-trained expert in the impact of light on the human circadian system, a Matthew Flinders Professor at Flinders University, and Co-Founder and CEO of Circadian Health Innovations (@HealthyLight247)
Humans are now living in a perpetual twilight, all the way up until bed, which is wrecking havoc on our circadian system and visibly showing up in population health studies.

Two hospitals in London in a space of 1 week added a rooftop sundeck for their ICU patients.
We also discuss the new MiEYE light sensor on this episode of MedCram!

Check out the upcoming video on the MiEye on MedCram tomorrow! Small clip can be seen here. As always, great content by @RogerSeheult
Why visual brightness might not mean IR irradiation and why it's better to be outside in greenery rather than a concrete jungle.

Sneak peak at tomorrow's offering on MedCram.
In time for the holidays, a gift from CHI to MiEye users: infrared light sensing! We’ve just released an app and firmware update allowing users to measure and record near infrared (NIR) light. This is a burgeoning research area, with very little on real-world exposure patterns.

🚨🚨MiEye: This is the ultimate wearable to measure light coming to your body in the visible (and also infrared apparently). I have no financial relationship with this company. But this would be a great way of showing how much light patients in a hospital get before and during an intervention!!!

Exposure to brighter light at night was associated with greater risk of developing coronary artery disease, myocardial infarction, heart failure, atrial fibrillation, and stroke, developing cardiovascular diseases among adults >40 years. ja.ma/47lgien

Light at night and heart disease! Published today in JAMA Network Open. We found that those with the brightest nights had higher risks of coronary artery disease, myocardial infarction, heart failure, atrial fibrillation, and stroke.

Preprint alert! Light at night predicts heart health. People with bright nights had significantly higher risks of coronary artery disease, myocardial infarction, heart failure, atrial fibrillation, and stroke.

The amount of blue in your light sculpts how you think and we are just beginning to understand this non-conscious influence. We found that blue light reduces sensitivity to loss. This likely impacts many decisions we make.

CHI Data Portal is live! Drag and drop your MiEye light data and a sleep diary for incredibly detailed light analysis and circadian phase & amplitude modeling. Some nice figures too! Go check it out and take a test drive with our sample data files here: circadianhealthinnovations.c…

Our latest work on the health impacts of light is out in The Lancet Regional Health-Europe. We examined personal light exposure in 85,000 people and found that the risk of developing diabetes was far greater in people exposed to more light at night. The good news is that healthy light patterns could mitigate genetic risk.
Work led by Daniel Windred, with @anguscburns, @circadianumbers, and a fantastic team of collaborators.
