Night owl

While staying up after dark was considered a negative trait, this changed in 17th and 18th century Europe (and subsequently spread beyond) due to the development and implementation of artificial lighting: more domestic lights, added street lighting, and adaptation by the royal and upper social classes. The introduction of chocolate, coffee and tea, and cafes that stayed open through dawn, became part of the new culture. Etymology in Poland, are often nocturnal. The term is derived from nocturnal habits of owls.{{Cite web |url=http://www.dictionary.com/browse/night--owl?s=t ==Characteristics==

Usually, people who are night owls stay awake past midnight, and extreme night owls may stay awake until just before or even after dawn. Some night owls have a preference or habit for staying up late, or stay up to work the night shift. Night owls who work the day shift often have difficulties adapting to standard daytime working hours. Night owls have often been blamed for unpunctuality or attitude problems. Employers, however, have begun to learn to increase productivity by respecting body clocks through flexible working hours, while the Danish "B-Society" of night owls However, they lag behind larks in academic performance, and they tend to have unhealthier eating habits, as well as higher rates of smoking. Some research suggests that night owls have a higher risk for bipolar disorder. Some night owls who have great difficulty adopting desired sleeping and waking times may have delayed sleep phase disorder. Morning light therapy may help to shift sleep rhythms for the night owl. Several studies have found that night owls may respond differently to some treatments for medical and mental health conditions compared to morning types. For example, a study of adults with depression found that higher eveningness was associated with more side effects and lower efficacy of selective serotonin reuptake inhibitors and selective norepinephrine reuptake inhibitors. == Psychology ==

The night owl pattern is more prevalent in men than in women. Night owls are more likely to be single than in long-term relationships. == Factors ==

The tendency to be a night owl exists on a spectrum, with most people being typical, some people having a small or moderate tendency to be a night owl, and a few having an extreme tendency to be a night owl. An individual's own tendency can change over time and is influenced by multiple factors, including: • a genetic predisposition, which can cause the tendency to run in families, • the person's age, with teenagers and young adults tending to be night owls more than young children or elderly people, and • the environment the person lives in, except for the patterns of light they are exposed to through seasonal changes as well as through lifestyle (such as spending the day indoors and using electric lights in the evening). While it has been suggested that circadian rhythms may change over time, including dramatic changes that turn a morning lark to a night owl or vice versa, evidence for familial patterns of early or late waking would seem to contradict this, and individual changes are likely on a smaller scale. ==Prevalence==

A 2007 survey of over 55,000 people found that chronotypes tend to follow a normal distribution, with extreme morning and evening types on the far ends. == Career options ==

Night owls tend to thrive in careers that do not require working in the early morning. People who want to work in the evening are often employed at restaurants, hotels, entertainment venues, retail stores, and some personal care businesses. Night owls who work the night shift may work in emergency services, in transportation, or at round-the-clock facilities, such as hospitals and some manufacturing plants. Many businesses that operate in the evening or at night need employees at all levels, from entry-level employees to managers to skilled staff, whenever they are open. For example, most hospitals employ many types of workers around the clock: • non-medical staff such as security guards, IT specialists, cleaning and maintenance workers, cooks and food service staff, and admissions clerks • medical staff such as nurses, paramedics, radiographers, pharmacists, and phlebotomists • managers for each of the main hospital wards or activities, including janitorial supervisors and head nurses. Industries that tend to be less favorable to night owls include farming, construction, education, and public utilities. Many employees in these industries start work before 7:00 a.m. == Downsides of night shifts ==

Night owls who opt to work night shifts may not be aware of the health risks associated with doing so. The body follows a circadian rhythm; the body's internal 24-hour clock which responds to natural environmental cues like sunlight and regulates hormone release. One key hormone in this cycle, cortisol, is responsible for maintaining homeostasis in the body. Cortisol levels peak in the early morning activating alertness and dwindle as night approaches to promote rest. Night shifts disrupt this cycle, mismatching the light and dark cycle and the cortisol secretion that is dependent on it. A few health risks associated with working night shifts include: • Anxiety • Depression • Day-time sleepiness • Decline in cognitive and physical performance • Insomnia • Obstructive sleep apnea • Metabolic dysregulation • Cardiovascular diseases A 2019 study found that night owl participants who shifted their sleep/wake cycle by 2 hours reported improvements in stress, anxiety, depression, and overall cognitive and physical performance. ==Notable people==
