Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

687
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

307
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Understanding Sleep

1.2K
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Primary Motives: Sleep, Sex, and Pain Avoidance

4.2K
Primary motives such as sleep, sex, and pain avoidance are crucial drivers of behavior in humans and animals. These motives ensure survival, reproductive success, and overall well-being by prompting actions that meet essential bodily needs.
Sleep is a fundamental physiological drive that fosters a state of restfulness crucial for several bodily functions. It facilitates body restoration, the process by which the body repairs, rejuvenates, and maintains itself during sleep, including memory...

Regulation of Food Intake01:30

Regulation of Food Intake

2.0K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

2.5K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Area of Science:

  • Sleep science
  • Obesity research
  • Appetite regulation

Background:

  • Short or poor sleep and disturbed circadian rhythms are linked to increased food intake.
  • Shift work disrupts sleep and circadian rhythms, potentially contributing to obesity risk.
  • The precise mechanisms linking shift work to altered food intake regulation remain unclear.

Purpose of the Study:

  • To investigate the relationship between sleep characteristics and hedonic appetite control in shift workers.
  • To explore how sleep quality and duration influence food cravings and the drive for palatable foods.

Main Methods:

  • A cross-sectional online survey was administered to 63 shift workers.
  • Validated questionnaires assessed body weight regulation, sleep quality (Pittsburgh Sleep Quality Index, Sleep Hygiene Index), and hedonic appetite control (Food Craving Inventory, Power of Food Scale).

Main Results:

  • 71% of shift workers reported weight changes, with 84% experiencing weight gain (average +11.3 kg).
  • Worse sleep quality and shorter sleep duration correlated with increased food cravings.
  • Poorer sleep quality and hygiene were associated with a higher hedonic drive for palatable foods.

Conclusions:

  • Disturbed sleep in shift workers is associated with heightened hedonic appetite pathways.
  • These findings suggest that impaired sleep contributes to increased food cravings and hedonic food drive, potentially leading to weight gain in this population.
