General Description (Fig. 1); Contraindications - Philips EnergyUp Intense Blue HF3420 Bedienungsanleitung

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.
