Pollution lumineuseLa pollution lumineuse est à la fois la présence nocturne anormale ou gênante de lumière et les conséquences de l'éclairage artificiel nocturne sur la faune, la flore, la fonge (le règne des champignons), les écosystèmes ainsi que les effets suspectés ou avérés sur la santé humaine. Comme celle de pollution du ciel nocturne qui la remplace parfois et qui désigne particulièrement la disparition des étoiles du ciel nocturne en milieu urbain, la notion de pollution lumineuse est apparue dans la deuxième moitié du et a évolué depuis.
Blood pressureBlood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured. Blood pressure is usually expressed in terms of the systolic pressure (maximum pressure during one heartbeat) over diastolic pressure (minimum pressure between two heartbeats) in the cardiac cycle.
Electric lightAn electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet mount.
