Human-Centric Lighting Proves Its Value in Hospitality – Key Takeaways
We wanted to share this compelling article on occupant lighting preferences with you that was just posted on Inside Lighting. It focuses on new research by Wasti & Chauhan, (2025) published in Scientific Reports, where 100 guests at four resorts were surveyed using questionnaires and field observations. It found that lighting tuned to human rhythms — especially lighting that mimics natural daylight cycles — had clear psychological benefits.
Beyond the Classroom: How Healthy Office Lighting Shapes the School Experience
School front office staff play a critical role in home-school relations. While much attention falls on students and teachers, non-teacher staff—secretaries, nurses, administrative assistants, custodial leads, counselors—play vital, often underappreciated, roles in school climate, operations, and student/parent/staff interactions (Thomson et al. 2007). Their alertness, mood, and well-being directly influence how smoothly the school functions. School offices and support rooms are often not subject to the same architectural daylighting and wellness considerations as classroom spaces, creating an inadequate environment for key functions.
A Window on Melanopic Light: How View Direction Dramatically Impacts Natural Light Exposure
One might say that the healing power of nature is real, but it depends on your point of view. This is particularly true of the health benefits of natural light. If we can see the daytime sky, even indoors through a window, we can be reasonably sure that we are getting the melanopic light we need to set and maintain our circadian rhythms, which drive our health and wellbeing. But what if we’re not looking out the window? It turns out that the impact of gaze direction on melanopic exposure is substantial. You could be turning your back on health.
SkyView™ Dampens Daylight Saving Effect in School Kids – Results from the Parent Study – Part 2
Every year, millions of people around the world adjust their clocks forward or backward by an hour as part of daylight savings (DLS) time. While the intention behind this practice is to optimize daylight hours and conserve energy, its effects on health can be profound and often overlooked. The shift in time disrupts our circadian rhythm, the internal body clock that regulates sleep-wake cycles, hormone release, and other fundamental physiological processes. This disruption can lead to a range of health issues, from mild discomfort to more serious conditions.
Circadian Lighting Improves Child Sleep Transitions and Mood – The Parent Study – Part 1
The rising of the sun is an evolutionary cue to our bodies to begin our days. The day’s sun brings energy, but it also synchronizes our circadian clock, our body’s rhythm that drives everything from energy levels, to metabolism, to mood and mental focus.
School and Hospital Wellness Rooms Seen in a New Light
Wellness and calming rooms are increasingly common in K–12 schools and hospitals to reduce stress, improve focus, and support emotional well-being. These spaces often include sensory tools, comfortable seating, and adjustable lighting. However, lighting is typically limited to changes in color or brightness, lacking the high-melanopic circadian lighting crucial for supporting, mood, alertness and regulating biological rhythms—especially important given that most classrooms and offices have bright but sky-blue-deficient lighting.
What is Circadian Lighting and How Does it Work?
Circadian lighting is a new frontier in indoor lighting design, aimed at supporting the body’s natural 24-hour internal clock—known as the circadian rhythm. Unlike traditional lighting, which prioritizes brightness and color rendering for visual tasks, circadian lighting is designed with biology in mind. It seeks to mimic the natural light cycle of the sun, signaling the brain when it’s time to be alert and active, and when it’s time to relax and prepare for rest.
Color Tuning VS. True Circadian Lighting for Improved Health
What if many of the things that ail us could be addressed by something as simple as proper exposure to natural light? Research findings over the past decade have granted new understanding about how our physical health and performance is linked to the sun and our natural sleep/wake cycle.
How Does Our Circadian Rhythm Affect Our Health?
Our circadian rhythm is best described as the natural cycle of mental, physical, and behavioral changes the body goes through in a 24 hour cycle. Often referred to as our “biological clock”, this system helps to regulate our bodies to function optimally within the cycle of a day.
In this blog we will discuss the affects of circadian rhythm and health by examining the underlying hormonal processes within that are governed by it. These hormonal processes can directly affect our mood, mental health, sleep quality, and even our productivity. Understanding how light affects these processes can help us to optimize our lives and improve our overall health.
Circadian Lighting Design Made Simple
The discovery that light fundamentally affects our health revolutionized how we think about lighting interior spaces. Lighting design now involves considerations of biology, especially the impact of illumination on circadian rhythm.
