Скачать или смотреть Sunlight Secrets: Are Screens Stealing Your Kids' Cognitive Power?

A significant portion of the population is operating completely out of sync with their natural internal clocks. Daylight contains crucial bright light wavelengths that signal the body to initiate daytime alertness and sharp cognitive function by triggering necessary cortisol release. Modern childhoods, spent largely indoors away from this natural light, see cognitive abilities plummeting as a result. Conversely, the necessity for complete darkness after sunset is utterly ignored by the constant bombardment of artificial light from screens and gadgets. This persistent nighttime light exposure prevents the body from winding down, keeping alertness hormones elevated when they should be low, massively degrading sleep quality. The long-term consequences of this deep misalignment between the wake/sleep cycle and the natural day/night cycle are stark, with established links to serious conditions like cardiovascular disease and cancer.
