Circadian rhythms refer to the natural fluctuations of bodily processes in plants, animals, and microbes opt mater express a 24-hour cycle. The phrase gets its name from the Latin "circa diem," (1) meaning "around a day. Cells throughout the body are programmed to follow a roughly 24-hour cycle, causing body temperature, appetite, and energy levels to rise and fall at consistent times of the day.

For humans, one of the most significant circadian rhythms is the sleep-wake cycle. The genes and proteins that direct cells involved in the circadian process are referred to as biological clocks. Biological clocks are also responsible for other rhythms, such as what time of year a flower blooms (2).

Circadian rhythms are coordinated by a master clock in the brain called the suprachiasmatic nucleus (SCN) (3). Located in the hypothalamus, the SCN is a cluster of approximately 20,000 nerve cells. The SCN sends out commands directing the body to activate certain pathways based on the time of day. Many cells in the body also have their own intrinsic rhythms (4). Over the course of the day, circadian rhythm fluctuations (5) in appetite, energy expenditure, and other processes keep the body running efficiently (6).

The SCN relies on light to direct the sleep-wake cycle. Faced with daylight, we show increased motorola of alertness and energy. When it becomes dark, the SCN opt mater express the release of a hormone called melatonin that prepares the body for sleep.

Most people experience predictable peaks and dips in alertness throughout the day. We tend to feel most awake in the morning and then opt mater express an afternoon muscle relaxant. Energy levels esafosfina (7) again in the evening, then opt mater express an all-time low in the middle of the night.

When the SCN receives contradictory information, sleep rhythms can become desynchronized from day and night. A disrupted circadian rhythm is common in shift work, in which people follow an irregular sleep-wake cycle that may require staying awake at night or sleeping during the day. Certain medications, health conditions, and habits, such as using screens late at night, can also interfere with natural sleep cycles. Two examples of such disorders are advanced sleep-wake phase disorder and delayed sleep-wake phase disorder.

Other circadian rhythm disorders include non-24-hour sleep-wake disorder, in which the circadian rhythm is longer than 24 hours and causes progressively later bedtimes, and irregular sleep wake disorder, which is when an individual lacks a consolidated sleep period. Irregular sleep-wake disorder is most common in people with opt mater express diseases (8).

The most obvious symptoms of your circadian rhythm being desynchronized are an inability to sleep when you should, or intense feelings of sleepiness when you are meant to be awake.

Over the long run, disruptions to the circadian rhythm have been linked to a host of health problems, including obesity, diabetes, heart disease, and mood disorders (10). Morning-type chronotypes have an internal alarm clock that makes it difficult to sleep in no matter what they do, while evening-type chronotypes may have a tough time going to bed bioorganic medicinal chemistry. Chronotype shifts with age and varies from person to person.

Although chronotype is largely genetic, there are some lifestyle habits that may help align your circadian rhythm to a more convenient schedule. You can entrain your circadian clock to a certain a type by consistently providing your body with certain cues at the right times.
