Are you one of the 1.5 million Brits taking sleeping tablets because of sleep problems? Poor sleep, which over time, leads to fatigue, reduced short-term memory recall, irritability, anxiety and lack of focus.
It is now known that any light but, in particular “blue light” (from TV, mobile, laptop and tablet screens) interferes with sleep. Worse still, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity.
Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night.
