Summary
Working rotating shifts negatively impacts health, causing sleep disorders, reduced productivity, and increased risks for chronic diseases like diabetes and cancer. Light can be used to mitigate these adverse effects.
Area of Science:
- Occupational Health
- Chronobiology
- Environmental Design
Background:
- Rotating shift work is prevalent across many industries.
- Shift work disrupts the natural circadian rhythm, leading to sleep disorders.
- Existing research indicates numerous adverse health outcomes associated with shift work.
Purpose of the Study:
- To review the health consequences of working rotating shifts.
- To explore implications of shift work for structural and environmental design.
- To identify countermeasures for mitigating circadian disruption.
Main Methods:
- A comprehensive literature search was conducted in June 2012.
- Peer-reviewed articles relevant to shift work and health were selected.
- The review synthesized findings on health effects and countermeasures.
Main Results:
- Shift workers experience higher rates of circadian sleep disorders (sleepiness, insomnia).
- Shift work is linked to decreased productivity, safety concerns, and reduced quality of life.
- Circadian disruption from shift work increases risks for metabolic syndrome, diabetes, cardiovascular disease, and cancer.
Conclusions:
- Rotating shift work poses significant health risks, including chronic disease development.
- Light exposure can serve as a countermeasure to reduce circadian disruption and maintain alertness.
- Design considerations, particularly regarding lighting in environments like newborn intensive care units, are important for mitigating negative impacts.

01:13Insufficient Sleep and Sleep Deprivation
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.

01:25Effects of Creep
Creep in concrete, the gradual deformation under prolonged stress, significantly impacts the integrity of structures. For reinforced concrete beams, it can be a vital design consideration, as it increases deflection, sometimes necessitating additional design measures. In columns, especially slender ones under eccentric loads, creep can cause buckling, compromising their stability. However, creep can be beneficial in indeterminate structures by mitigating stresses that arise from shrinkage,...
01:22Design Consideration
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.

01:24Stress Concentrations
Stress concentration is when stress intensifies near discontinuities such as holes or abrupt cross-sectional changes in a structural member. This localized stress can often surpass the average stress within the member. The stress distribution in flat bars, either with a circular hole or varying widths connected by fillets, can be determined experimentally using a photoelastic method. The results are based on ratios of geometric parameters like the ratio of the hole's radius to the smaller width...
01:13Stress Concentrations
The concept of stress concentration is crucial for understanding how materials respond under bending stresses, particularly when there are irregularities or discontinuities in the material's geometry. Normally, stress in a symmetric member subjected to pure bending is assumed to be uniformly distributed across the entire cross-section. However, this assumption does not hold when there are variations in the cross-sectional geometry or the presence of notches and holes.

02:19Circadian 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 years,...
