Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Circadian Rhythms and Gene Regulation

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Understanding Sleep

Understanding Sleep

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...

Lifestyle Factors and Health

Lifestyle Factors and Health

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Sympathetic Activation

Sympathetic Activation

The sympathetic division can influence tissues and organs by releasing norepinephrine at peripheral synapses and distributing epinephrine and norepinephrine through the bloodstream. In times of crisis or stress, sympathetic activation occurs, which is regulated by sympathetic centers in the hypothalamus. As a result, sympathetic activation prepares the body for physical exertion, rapid ATP production, and heightened alertness, allowing individuals to respond effectively to challenging or...

Primary Motives: Sleep, Sex, and Pain Avoidance

Primary Motives: Sleep, Sex, and Pain Avoidance

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...

Summary

Evening chronotypes are linked to reduced physical activity (PA) and increased sedentary behavior, particularly in adults. This association may be less pronounced in younger individuals.

Background:

Understanding the relationship between an individual's internal biological clock (chronotype) and their daily physical activity patterns is crucial for public health.
Chronotypes, often categorized as morningness or eveningness, may influence lifestyle choices, including physical activity levels and sedentary behavior.

Purpose of the Study:

To systematically review and evaluate the existing scientific evidence on the association between chronotypes and physical activity (PA).
To synthesize findings from diverse studies to provide a comprehensive overview of this relationship.

Main Methods:

A systematic literature search was conducted across major databases: PubMed, Cochrane Library, PsycInfo, and Trip Database.
Keywords included 'chronotype,' 'sleep,' 'physical activity,' and 'sedentary behavior,' utilizing MeSH terms for precision.
The Joanna Briggs Institute (JBI) critical appraisal tools were employed to assess the methodological quality of the included studies.

Main Results:

The review analyzed 23 studies encompassing 505,375 participants.
A consistent association was found: evening chronotypes exhibit lower levels of physical activity and higher engagement in sedentary activities compared to morning chronotypes.
This association was independent of the specific tools used for chronotype and physical activity assessment.

Conclusions:

Chronotypes significantly correlate with physical activity levels and sedentary behavior, especially in individuals over 25 years old.
Evening chronotypes consistently demonstrate reduced physical activity and increased sedentary time relative to morning chronotypes.
The identified association between chronotype and physical activity/sedentary behavior may be attenuated in younger populations, such as university students.
