Studies show that at night blue light has negative effects on our health. This is because blue light is a trigger for our attention and causes a better reaction time. At night, when our bodies are expected to sleep and rest, exposure to blue light disrupts the body’s natural recovery rhythm. Blue light is usually emitted by energy efficient lighting, laptops, and cellular phone screens. You should try to avoid blue light exposure a few hours before bedtime. If you cannot avoid using your cellphone in bed, it is best that you enable night mode to minimize the effects of blue light. This tutorial demonstrates how to enable the blue light filter feature on Samsung Galaxy phones running on the Nougat OS.
