Summary
Occupational high-temperature exposure significantly accelerates biological aging (BA) and organ-specific BA. High-temperature exposure and BMI interact to influence BA acceleration, with high temperatures, BMI, and smoking being risk factors.
Area of Science:
- Occupational Health
- Gerontology
- Biomarkers of Aging
Background:
- Biological aging is influenced by various environmental and lifestyle factors.
- Occupational exposure to high temperatures is a growing concern in industrial settings.
- Understanding the impact of occupational hazards on aging is crucial for public health.
Purpose of the Study:
- To investigate the association between occupational high-temperature exposure and accelerated biological aging.
- To determine the influence of factors like BMI, smoking, and sleep on biological age acceleration.
Main Methods:
- A study involving 140 male workers exposed to high temperatures and 207 controls.
- Biological age (BA) and organ-specific BA calculated using the Klemera-Doubal method.
- Generalized linear models used to analyze risk factors for BA acceleration.
Main Results:
- Workers exposed to high temperatures showed significantly accelerated biological aging (BA) and liver-kidney BA.
- High-temperature exposure, BMI, and smoking were identified as risk factors for BA acceleration.
- Sleep duration was found to be a protective factor against BA acceleration.
Conclusions:
- Occupational high-temperature exposure is linked to accelerated biological aging.
- An interaction between high-temperature exposure and BMI significantly affects biological age acceleration.

01:26Aging
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:19Homeostatic Imbalances in Body Temperature
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...
01:37Mitochondria
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
