Light therapy, also known as phototherapy, uses specific wavelengths and intensities of light to treat various conditions and optimize wellness. When natural sunlight is insufficient, therapeutic light can fill the gap effectively.
Understanding Light Therapy
Not all light therapy lamps are created equal. Medical-grade devices provide 10,000 lux at a comfortable sitting distance, mimicking the intensity of outdoor morning light. This brightness is crucial for triggering the biological responses we need.
When to Use Light Therapy
Morning is optimal, ideally within 30 minutes of waking. Position the lamp 16-24 inches from your face at a slight angle—not directly in front of your eyes. Twenty to thirty minutes is typically sufficient, though some people benefit from longer sessions during darker winter months.
Who Benefits Most
People with seasonal affective disorder, shift workers, those living in northern climates, and anyone experiencing disrupted sleep patterns can benefit significantly. However, individuals with certain eye conditions or taking photosensitizing medications should consult a healthcare provider first.
Consistency matters more than perfection. Daily use yields the best results, building and maintaining the circadian rhythm adjustments over time.
