iltimeikki

Iltimeikki, also known as "night owl" or "night person," refers to an individual who is most active during the nighttime hours, typically from midnight to 4 AM. This circadian preference is often associated with a later chronotype, meaning that their body's internal clock is set to a later schedule than the average person. Iltimeikki individuals may experience a range of effects, including improved productivity during nighttime hours, difficulty sleeping during the day, and a higher risk of certain health issues such as obesity and cardiovascular disease.

The term "iltimeikki" is derived from Finnish, where "ilta" means "evening" and "kiikki" means "owl." This reflects the Finnish cultural association of owls with nighttime activity. The concept of iltimeikki is not limited to Finland and is recognized in various cultures around the world.

Research suggests that iltimeikki individuals may have a genetic predisposition to their circadian preference, although lifestyle factors such as shift work, social schedules, and exposure to artificial light can also influence chronotype. Understanding one's chronotype can help individuals optimize their schedules, improve sleep quality, and enhance overall well-being.
