Blue Light and Sleep Patterns
One of the most helpful pieces of mobile device technology is how they emit blue light to allow them to be seen even when it’s sunny. Your smartphone, tablet, and laptop all use blue light in their screens to make it easy to read content. But blue light isn’t all sunshine and rainbows. It also has a dark side, which comes into play when you’re trying to get the high-quality sleep you need to thrive. Blue light has been found to suppress the production of melatonin, the hormone that helps you get to sleep at night. In nature, blue light is most plentiful during the morning hours, which tells our brains that it’s time to be alert. On the other side of the spectrum is red light, which is abundant when the sun sets and gives us the signal that it’s time for sleep. That’s where blue-light-emitting devices like smartphones become problematic. Mother Nature is trying to help our bodies get to sleep by generating red light. But we’re bombarding ourselves with “morning signals” by using our phones or tablets in bed.Health Risks of Blue Light
Using your cellphone in bed won’t just make you feel groggy in the morning. Blue light can also have some scary effects on your health. The following health risks have all been associated with too much exposure to blue light.- Diabetes and obesity
- Anxiety and depression
- Impaired memory and focus
- Early onset of heart disease
