How light affects our body
clock and energy levels
Our body clock influences the timing of all our bodily
rhythms: our sleeping and waking patterns, alertness,
performance levels and metabolism. These rhythms
vary regularly (up and down) over a 24-hour cycle,
and are influenced by light. To time these rhythms,
photoreceptors in our eyes detect bright light. This
is why the
focuses light on your eyes.
Often, however, we do not receive the daily bright
light we need to maintain a well-timed body
clock and natural energy levels. This can be due
to working indoors, seeing too little sun during
the long winter months, or deliberately avoiding
the sun because of concern over UV rays. Indoor
lighting is usually not sufficient to time our body
clocks. The
was created to provide
a portable and 100% UV-free light source.
