A collection of symptoms that arises from a mismatch between the body's internal circadian cycles and the external environment. A common cause for this desynchronization is traveling across multiple time zones.

Jet Lag

Insomnia is defined as constant difficulties falling or being asleep. It can also be accompanied by an increase in levels of anxiety.

Insomnia

Rotating shift work is a work schedule that changes frequently, often from early to late shifts on a daily or weekly basis. This constant change makes it difficult for an individual to maintain a stable, normal circadian rhythm.

Rotating Shift Work

A parasomnia is a type of sleep disorder characterized by undesirable and disruptive motor activities or experiences that occur during sleep. These events can take place during either the REM or NREM phases of the sleep cycle.

Parasomnia

Based on the scenario provided, identify the most likely sleep disruption this individual is experiencing and justify your choice by citing at least two specific pieces of evidence from the text.

One's circadian rhythm is a daily cycle that regulates itself in accordance to the outside world. When this cycle is thrown off, it negatively impacts sleep regulation and can lead to disruptions of normal sleep. 

Problems with Circadian Rhythms

Sleep disorders include:
- Parasomnia
- Insomnia
- Sleep Apnea
- Sudden Infant Death Syndrome (SIDS)
- Narcolepsy

The pineal gland is an endocrine structure located within the brain that produces and releases the hormone melatonin. It plays a significant role in regulating various biological rhythms, including sleep-wake cycles, and is also believed to be involved in modulating the immune system during sleep.

Disruption of Normal Sleep

A misalignment between the body's internal biological clock and the external environment, often caused by factors like cross-time-zone travel or rotating work shifts, can lead to various negative effects, including insomnia, excessive sleepiness, and reduced alertness.

Consequences of Circadian Rhythm Disruption

Based on the provided scenario, explain the most likely underlying biological reason for the worker's difficulties with sleep and alertness.
