Diurnal

Diurnal refers to the active phase of a 24-hour cycle, typically associated with daylight hours. This term is often used in various fields such as biology, medicine, and astronomy to describe patterns that occur during the day.

Biology[edit | edit source]

In biology, diurnal patterns refer to the activities or behaviors of organisms that are active during the day and rest at night. This is the opposite of nocturnal organisms, which are active during the night. Diurnal organisms include many types of birds, reptiles, and primates, including humans.

Medicine[edit | edit source]

In medicine, diurnal variations are changes in bodily functions or symptoms that occur during the day. For example, certain medical conditions such as rheumatoid arthritis and asthma may show diurnal variations, with symptoms worsening or improving at certain times of the day.

Astronomy[edit | edit source]

In astronomy, diurnal motion is the apparent daily motion of stars around the Earth, or more precisely around the two celestial poles. It is caused by the Earth's rotation on its axis and is observed as the rising and setting of stars and other celestial bodies.
