No Blue Light at Night

If you have trouble sleeping, limit your use of digital devices hours before bedtime.  The blue light may reduce the body’s production of melatonin, a hormone that helps promote sleep.  In a recent small study, participants wore special yellow-tinted, blue-light-blocking glasses for four hours before bedtime.  After 2 weeks, subjects had a 60% increase in their melatonin levels, slept longer and logged better sleep quality.  In addition to limiting screen time before bed, try setting devices to night mode or applying blue-light filters to screens.  There are also apps that will automatically warm up the color temperature of the screen, based on time zones.
