'While it may not be immediately obvious as to why, light is actually crucial to your health. I've always believed that you could have the ideal lifestyle with respect to the food you're eating, the water you're drinking, and exercise, but if you don't sleep well, you're just not going to be optimally healthy.
Poor sleep inevitably leads to health problems. Maintaining a natural rhythm of exposure to daylight, and darkness at night, is an essential component of sleeping well.
Researcher Dan Pardi, who is employed by the Behavioral Sciences Department at Stanford University, also works with the departments of neurology and endocrinology at Leiden University in the Netherlands.
"I look at how sleep deprivation, or not getting enough sleep or the amount of sleep that you need, can influence decision making and cognitive processes like reaction time, memory, impulsivity, and how that relates to food choice," he explains.'
