Seasonal Affective Disorder (SAD)

BIOPTRON® Hyperlight is clinically tested and certified to fight seasonal affective disorders (SAD)

SAD is characterized by a combination of symptoms such as:

  • Chronic fatigue
  • Lowered motivation
  • Anhedonia (inability to feel/perceive happiness)
  • Increased need of sleep
  • Changes in appetite or weight
  • Loss of interest in activities you once enjoyed
  • Feeling sluggish or agitated
  • Difficulty to be focused and concentrated
  • Social withdrawal

SAD is a type of mood disorder in which the depressive symptoms show progression in a seasonal pattern, typically starting in the late autumn and early winter.

The exact cause of SAD is unknown, but researchers have found some biological clues related to a disruption of our circadian rhythms.

Circadian rhythms are metabolic, physical, mental and behavioural changes that follow a daily cycle. One of the most known is the sleep-wake cycle. Scientists believe that a shortage of light may have a negative effect on our sleep rhythms, because it disrupts the regulation of synthesis pathways of important neurotransmitters, such as serotonin and melatonin, as well as the production of Vitamin D.


BIOPTRON® Hyperlight Therapy provides safe and needed dose of daily exposure to bright light.

BIOPTRON® Hyperlight has the properties of natural light: it increases the production of serotonin and recharges your batteries with positive energy.
