Crepuscular
Crepuscular (/krɪˈpʌskjʊlər/), from the Latin word crepusculum, meaning "twilight", is a term used in various fields of study such as zoology, astronomy, and medicine to describe certain behaviors or phenomena that occur during the twilight hours at dawn and dusk.
Etymology
The term crepuscular is derived from the Latin crepusculum, which means "twilight". It is used to describe anything related to twilight or occurring during this time. The term was first used in English in the 17th century.
In Medicine
In the field of medicine, the term crepuscular is used to describe certain symptoms or conditions that become more pronounced or occur exclusively during the twilight hours. For example, some patients with migraine or epilepsy may experience increased symptoms during these times. This is thought to be related to changes in the body's circadian rhythm and light levels.
