I have a dear friend who when exposed to the light from CFL bulbs (even indirectly), it triggers photosensitivity seizures... it’s heartbreaking, but the best thing is to simply avoid the trigger. Related... and I have no clue ho2 common this is, but the strobing blue LEDs they use on modern lightbars on cop cars “bother” me... it’s hard to explain... it makes me feel nauseated... I guess like those “puke lights” they came out with to intentionally disorient people.
From the Harvard Medical Review:
But all light is not created equal, says the Health Letter. Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night.
Studies have linked ...light at night to several types of cancer (including breast and prostate cancer), diabetes, heart disease, and obesity.
Use dim red lights for nightlights. Red light has the least power to shift circadian rhythm and suppress melatonin.
Avoid looking at brightly lit screens beginning two to three hours before bed.
If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses.
Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.
