Nicotinamide adenine dinucleotide, a coenzyme critical for cellular energy metabolism that declines with age. NAD+ precursors like NMN and NR are studied as longevity interventions.

Mechanistic target of rapamycin, a key nutrient-sensing pathway that regulates cell growth and aging. Inhibiting mTOR (e.g., with rapamycin) has shown lifespan extension in multiple organisms.

A class of drugs that selectively eliminate senescent (aged, dysfunctional) cells to reduce inflammation and improve tissue function.

What is Epigenetic clock?

A biomarker based on DNA methylation patterns that estimates biological age, often more predictive of health outcomes than chronological age.

The period of life spent in good health, free from chronic diseases and disability associated with aging.

An immunosuppressant drug that inhibits the mTOR pathway. Research shows rapamycin may extend lifespan and improve age-related health outcomes in multiple species.

What is Biological age?

A measure of how well or poorly your body is functioning relative to your chronological age, assessed through biomarkers such as DNA methylation, telomere length, and blood panels.

What is Caloric restriction?

A dietary regimen that reduces calorie intake without malnutrition. Caloric restriction is one of the most studied interventions shown to extend lifespan across species.

Protective caps at the ends of chromosomes that shorten with each cell division. Telomere length is associated with aging and age-related diseases.

A state in which cells permanently stop dividing but resist death, accumulating with age and secreting inflammatory factors that damage surrounding tissue.

A second-generation epigenetic clock that predicts time to death and is considered one of the most accurate measures of biological aging.

What is Inflammaging?

Chronic, low-grade inflammation that increases with age and contributes to the development of age-related diseases including cardiovascular disease, diabetes, and neurodegeneration.

The large-scale study of proteins in biological systems. In longevity research, proteomics identifies blood protein signatures that predict biological age and disease risk.

What is Yamanaka factors?

A set of four transcription factors (Oct4, Sox2, Klf4, c-Myc) that can reprogram adult cells to a pluripotent state. Partial reprogramming with Yamanaka factors is being explored to reverse cellular aging.

Nicotinamide mononucleotide, a precursor to NAD+ that is widely studied as a supplement to boost cellular energy and combat age-related decline.

A gene-editing technology that allows precise modifications to DNA. In longevity research, CRISPR is used to study and potentially modify genes associated with aging.

A cellular housekeeping process where cells break down and recycle damaged components. Declines with age and is stimulated by fasting.

What is Intermittent fasting?

An eating pattern that cycles between periods of fasting and eating. Various protocols (16:8, 5:2) are studied for metabolic, cardiovascular, and longevity benefits.

What is Zone 2 cardio?

Low-intensity aerobic exercise performed at roughly 60–70% of maximum heart rate, primarily using the aerobic energy system. Associated with mitochondrial health and longevity.

Geographic regions identified by researchers where people consistently live longer and healthier lives than average, including Sardinia, Okinawa, and Loma Linda.

Does Poor Sleep Speed Up Aging?

Researchers found that poor sleep quality is linked to a faster pace of aging, but the evidence for whether it actually causes aging to speed up is mixed. As we age, sleep quality tends to decline, which can lead to various health issues. This correlation raises questions about whether improving sleep could help slow aging and prevent diseases. However, the relationship between sleep and aging is complex, with some factors possibly contributing to both poor sleep and accelerated aging.

For people who want to age well, this research highlights the importance of sleep. The study analyzed data from over 64,000 adults across different age groups and found a strong correlation between poor sleep and various aging biomarkers. This suggests that if you struggle with sleep, it might be worth addressing to potentially improve your overall health and longevity. However, it’s essential to note that while the correlation is strong, the evidence does not definitively prove that poor sleep causes faster aging.

The findings come from a comprehensive analysis that examined multiple datasets, but they also indicate that the relationship between sleep and aging is not straightforward. While poor sleep is associated with a higher risk of disease and mortality, the evidence for a direct causal link is inconsistent. This means that while better sleep might be beneficial, it is not guaranteed to slow the aging process.

In summary, focusing on improving sleep quality is a worthwhile endeavor for those interested in healthy aging, but further research is needed to clarify the nature of the relationship between sleep and aging.
