Biohacking Glossary

A natural substance that helps the body adapt to stress and maintain homeostasis.

A cellular self-cleaning process that degrades and recycles damaged cellular components.

Brain-Derived Neurotrophic Factor; a protein that promotes neuron growth, survival, and plasticity.

The practice of using science, technology, and self-experimentation to optimize human biology and performance.

A measurable biological indicator used to assess health status, disease progression, or biological processes.

High-energy visible light (450-495nm) that suppresses melatonin production and affects circadian rhythm.

The body's internal 24-hour clock governing sleep-wake cycles, hormone release, and metabolism.

A wearable device that tracks blood glucose levels in real time via a subcutaneous sensor.

Clustered Regularly Interspaced Short Palindromic Repeats; a gene-editing technology enabling precise DNA modification.

Changes in gene expression caused by mechanisms other than alterations to the DNA sequence itself.

Molecular chaperones produced in response to thermal stress that help repair and protect proteins.

A dose-response phenomenon where low-dose stressors produce beneficial biological adaptations.

Heart Rate Variability; the variation in time between heartbeats, indicating autonomic nervous system health.

An eating pattern that cycles between periods of fasting and eating on a regular schedule.

A metabolic state where the body uses ketone bodies from fat breakdown as its primary energy source.

The ability to efficiently switch between carbohydrate and fat oxidation based on fuel availability.

Nicotinamide Adenine Dinucleotide; a coenzyme critical for cellular energy production and DNA repair.

The brain's ability to form and reorganize synaptic connections, especially in response to learning or injury.

Any substance that enhances cognitive function, including memory, focus, creativity, or motivation.

The study of the relationship between nutrition, genetics, and gene expression.

The use of red and near-infrared light to stimulate cellular function and promote healing.

The practice of tracking personal biological data using technology to optimize health decisions.
