Sunlight
The original input.
Light is a signal the body is built to receive. Morning sun anchors the circadian clock and the cortisol pulse that wakes you; daylight exposure supports vitamin D, mood, and the sleep pressure that gathers by night. Alongside cold and heat, it completes the set of natural inputs. These articles cover the science of getting enough.
