What type of desktop light help with circadian rhythm, mood (SAD), or sleep patterns?Updated a month ago

If you are following Dr. Berg’s recommendations, he often highlights these three things when choosing a light:

• Intensity (Lux): For mood support, you generally need 10,000 lux at a specific distance (usually 12–18 inches) to effectively signal the brain.

• Full Spectrum: Look for "Full Spectrum" bulbs that mimic natural sunlight without harmful UV rays.

• Timing: Dr. Berg emphasizes using bright light within the first hour of waking up to help suppress melatonin and boost morning cortisol for better energy.
