How Blue Light Blocking Improves Sleep Tracker Scores

How Blue Light Blocking Improves Sleep Tracker Scores

Blue light from screens suppresses melatonin. Your sleep tracker measures the effect. Wonder Sleep users wearing blue-blocking glasses 2 hours before bed saw sleep onset drop from 35 to 18 minutes. Deep sleep increased 12 minutes. Phone screens are worst due to close viewing. Enable night mode after sunset. Your sleep tracker confirms improvement within 2-3 nights.
