    AbstractAging is an inevitable life process which is accelerated by lifestyle and environmental factors. It is an irreversible accretion of molecular and cellular damage associated with changes in the body composition and deterioration in physiological functions. Each cell (other than stem cells) reaches the limit of its ability to replicate, known as cellular or replicative senescence, and consequently, the organs lose their physiological functions, resulting in overall impairment. Other factors that promote aging include smoking, alcohol, UV rays, sleep habits, food, stress, sedentary lifestyle, and genetic abnormalities. These stress factors can alter our endogenous clock (the circadian rhythm) and the microbial commensals. As a result of the effect of these stressors, the microorganisms that generally support human physiological processes become baleful. The disturbance of natural physiology instigates many age-related pathologies, such as cardiovascular diseases, chronic obstructive pulmonary disorder, cerebrovascular diseases, opportunistic infections, high blood pressure, cancer, diabetes, kidney diseases, dementia, and Alzheimer's disease. The present review covers the three most essential processes of the circadian clock; the circadian gene mechanism and regulation, the mitotic clock (which plays a vital role in the telomere's attrition) and the gut microbiota and their metabolome that drive aging and lead to age-related pathologies. In conclusion, maintaining a synchronized circadian rhythm, a healthy gut microbiome, and telomere integrity is essential for mitigating the effects of aging and promoting longevity. The interplay among these factors underscores the importance of lifestyle choices in enhancing overall health and lifespan.© 2024 The Author(s). Published by S. Karger AG, Basel.
