Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.

Why afternoon sunlight could be keeping your teen awake at night

Bright afternoon and early evening light exposure in adolescents leads to lower melatonin levels and delays circadian rhythms, instead of protecting against evening light effects. Long-term light history, especially morning exposure, may help align adolescent sleep cycles.
