To learn more about the differences between natural and artificial light, check out the side-by-side comparisons below!  As a scientist i'm always curious about our natural world.  I carry around a spectrometer which allows me to 'see' the mix of colors and intensities in light (much like a [...]

light and the winter blues

2017-11-01T14:59:29+00:00

We need light to feel energized and happy.  Our mood and energy depend upon getting sufficient bright light during the day to signal ‘awake and alert’.  Without this signal, our bodies can’t clearly distinguish between night and day, and don’t provide the energy and hormones we need to [...]

2018-06-24T14:44:01+00:00

Exposure to natural light is a critical ingredient for a good night’s sleep - but most people don't understand that we need BOTH bright light during the day, AND biological 'darkness' to sleep well at night.  Blue light and sleep are fundamentally tied together - our bodies depend [...]

Our internal clock governs our health and wellness

2017-10-03T14:43:18+00:00

Humans, plants and animals have internal clocks which are synchronized by the daily cycle of light and dark.  In October 2017 the Nobel Prize in Medicine was awarded to three researchers for their work on the underlying mechanisms which govern the internal clock of living organisms.   Sir Paul [...]

Natural light is fundamentally different than artificial light

2017-09-22T17:20:00+00:00

Natural light is fundamentally different than the artificial light sources which we use in our homes, offices and schools. (1) Natural light is full spectrum, which means it contains all the colors of the rainbow, as well as wavelengths (colors) that we cannot see (infra-red and ultra violet). [...]

solar eclipse observations

2017-08-25T13:55:53+00:00

The August 2017 solar eclipse offered an incredible opportunity to witness how natural light colors our world.  For those outside the path of totality the eclipse was almost imperceptible as our eyes automatically adjust for the changing intensity of the sun = 5% of the sun is still [...]

how much natural light do we need (for our health)?

2017-07-22T13:51:36+00:00

Our bodies rely on the daily cycle of natural light from bright and blue during the day to soft and warm in the evenings (and then darkness) to synchronize our circadian rhythms, and thereby regulate our health and wellness.   Insufficient light during the day leaves us feeling flat.  [...]

natural light for infants (and caregivers)

2017-06-26T15:08:43+00:00

Natural light underpins the health and wellness of infants and their caregivers.  As any new parent knows, babies are born without a well-developed sense of night and day, and their internal body-clocks need external cues to help establish their sleep wake/cycle.  Infants depend upon exposure to the daily [...]

using light at night safely

2017-06-20T23:41:07+00:00

Our health and wellness depends upon the daily cycles of natural light, but we don't have to live in darkness after sunset - we just have to be smart about how we use artificial light.  To put it simply: after dark we should avoid bright blue light which [...]
