Chronotypes refer to an individual's natural preference for being active during certain times of the day, typically categorized as morning larks or night owls. Research indicates that these chronotypes are influenced by biological clocks and can shift as people age. For instance, teenagers often exhibit a later chronotype, while older adults tend to become early risers. This shift can have significant implications for health and productivity, as night owls may experience higher risks of health issues and cognitive decline. Studies have shown that night owls may be more creative and intelligent, but these claims are debated among experts. Ultimately, understanding one's chronotype can help individuals make informed lifestyle choices that align with their natural rhythms.
