Light via eyes
Research shows that a special photoreceptor in our eyes is responsible
for regulating our energy, mood and sleep/wake cycles. This receptor
responds mostly to the blue light of the summer sky. We do not get much
of this light in autumn and winter. Most indoor light does not provide
enough of this essential colour. This appliance helps you to be at your best
by delivering the wavelength, colour and intensity of light to which our
body responds most efficiently.
Winter blues
Lack of light during the darker winter months causes many people to
experience a noticeable drop in energy level and low spirits as autumn
sets in. These symptoms, known as 'winter blues', may cause you to feel
low, listless and fatigued for weeks or even months. This affects both
personal performance and mood. Blue light therapy is a successful
method to fight these winter blues symptoms. It provides your body with
summer vitality throughout the dark winter months.
