Blue Light and Better Sleep
If you stay up late watching TV or your computer screen because you can't sleep, blue light may be to blame.
Blue light comes from both the sun and artificial light sources, and is something we need. In the morning, it helps us wake up and know that the day has started. It keeps us happy, focused, and stops our bodies from making melatonin, which makes us tired.
The problem with blue light is when we're exposed at nighttime. Bright TV, computer, and phone screens can make it difficult to sleep. Our brains still really want bright light during the morning and light to stop in the evening.
Try getting out into bright light first thing in the morning and don't watch TV late at night. If you do, glasses with orange lenses can block some of the blue light. Keep lights in your bedroom dim---using lightbulbs that are just enough to read by is better than having bright ones.
