Timing

Lately I have been following the guidelines to avoid excessive blue light.  This applies to LED in particular, as found in light fixtures and most electronic device screens.  The guideline that is most affected by timing is stopping the use of such screens and bulbs an hour before my intended bedtime.  I replaced the bulbs in my bedroom ceiling light from LED back to the original bulbs which I found were recommended for their red light component.  I received incandescent bulbs from Amazon today and I am currently using one in the lamp that shines over my shoulder.  I believe I can detect the difference in the way it affects my general sense of wellbeing.  LEDs tend to cause a heavy feeling in my brow.  So I am grateful for learning about how to time my exposure to the useful but problematic lights I have long taken for granted.
