UV energy triggers skin-protective responses against stress, coordinated by the cutaneous-neuroendocrine system, and activates central neuroendocrine system pathways that regulate global homeostasis. The sensory and computing capabilities of the skin are designed to control cutaneous and body homeostasis (1).
3 Νοε 2017 · In this chapter, we review how light affects humans: first by describing the ways in which light impacts physiology and behavior, and then by discussing how different char- acteristics of...
sorily here, this review focuses on exploring the role of UV and, to a lesser degree, of visible light (VIS) in the regulation of central nervous system (CNS) and endo-crine gland functions and overall body homeostasis. Why Is UV Important? The electromagnetic energy of solar radiation reaching Earth’s surface encompasses infrared (700 nm to ...
UV radiation is divided into four distinct spectral areas, including vacuum-UV (100–200 nm), UVC (200–280 nm), UVB (280– 315 nm), and UVA (315–400 nm). 2 This division allows the...
that ultraviolet and red wavelengths are the least potent. The action spectrum plotted from these results closely follow the absorption spectrum for rhodopsin, the photosensitive pigment in the rods of the retina. The best-characterized indirect effect of light on any process other than vision probably the
1 Μαρ 2024 · Solar radiation is the Earth's predominant energy source, containing a substantial quantity of ultraviolet (UV) rays. UV radiation exists mainly in the form of electromagnetic energy, which is invisible and imperceptible to human senses, and has both good and bad effects on human health.
This book is about the roles and importance of Ultraviolet (UV) light from sun and from man-made UV lamps in our daily life, on health and diseases, also its application in sterilization and treatment.
