Blue wavelengths are shorter than other colors in the visible light spectrum and emit more energy. It's beneficial during the daytime as it boosts alertness, improves memory and has positive benefits on your mood.
Exposure to excess blue light at night through artificial lighting, mobile devices and computer screens has been proven to disrupt the circadian rhythms that regulate sleep patterns. It tricks your internal clock into thinking that it is the middle of the day. This causes difficulty in falling asleep, insomnia, and can result in daytime fatigue.
