Blue Light and Melatonin Levels Relating to Sleep

The research into sleep therapy is taking off in recent years. In particular, more research is dedicated into to finding out how blue light affects sleep patterns. It turns out that perhaps the single biggest contributor to our collective sleep problems, is the use of artificial lighting and electronics at night. These devices emit light of a blue wavelength, which tricks our brains into thinking that it is daytime . Numerous studies suggest that blue light in the evening disrupts the brain’s natural sleep-wake cycles, which are crucial for optimal function of the body . If by using technology, we can lower the level of electronic light or filter it out someway, sleep can be the best part of everyones day. This matters because more and more people are loosing sleep due to late nights in front of computers and they have no idea how badly this is affecting their sleep and mood patters through out the day.

This specific example in this study used a Inferred red camera connected to sensor wristband that records sleep positions during the night. This shows the sleep pattern of a user and the data is able to be used to create a mroe flexible sleep schedule pattern for the user.
