This device is a specific type of light therapy product designed to mimic natural daylight. It aims to provide users with a source of bright, full-spectrum light typically absent during certain seasons or indoor environments. Such devices are often employed to mitigate symptoms associated with Seasonal Affective Disorder (SAD) or general circadian rhythm disruption.
Light therapy’s efficacy stems from its ability to influence the body’s natural sleep-wake cycle and mood regulation. Exposure to bright light can stimulate the production of serotonin, a neurotransmitter linked to feelings of well-being, and suppress the production of melatonin, a hormone associated with sleepiness. This principle has been utilized in various forms since the 1980s, with advancements in technology leading to more convenient and user-friendly devices for home use.
