Light therapy can be a helpful option for people who notice their mood, motivation, or energy dip during the winter months. It is not a cure, but many people find it supportive as part of their routine for Seasonal Affective Disorder.
Shorter days and darker mornings affect your brain chemicals and circadian rhythm. This can lead to tiredness, irritability, cravings, low motivation, and difficulty waking up. Light therapy gently gives your brain the bright light it normally receives from morning sunlight, which may help you feel more awake and balanced.
If you are curious about trying light therapy, here are a few general suggestions:
• Look for a light box that is 10,000 lux
• Sit about 16 to 24 inches away
• Use it within the first hour of waking
• Start with 20 to 30 minutes
• Keep your eyes open but avoid looking directly at the light
• Use it consistently for best results
• Avoid late afternoon use so your sleep is not disrupted
Some people feel improvement within one to two weeks. Light therapy may work even better when paired with morning sunlight, daily movement, a steady sleep routine, therapy, or medication when needed.
