According to the Sleep Foundation, the half-life of caffeine can range from 2 to 12 hours, a massive variability that explains why its effects differ so widely among people. This significant variance is often the key to understanding why some individuals feel the stimulating effects of a morning coffee much later in the day, sometimes long after the initial buzz has subsided.

According to research, approximately 10% of the population is classified as hypersensitive to caffeine, experiencing significant side effects even with low intake. This heightened sensitivity can turn a morning coffee ritual into an uncomfortable experience, but what causes someone to be sensitive to caffeine?

According to scientific estimates, the heritability of caffeine-related traits ranges between 35% and 77%. This significant genetic component explains why some individuals can drink an espresso before bed without issue, while others get jitters from a small cup of tea, and whether caffeine tolerance can be genetic.

According to the International Coffee Organization, coffee consumption in developed countries is significantly higher than in developing countries, yet reactions vary widely across individuals. This remarkable variance explains how can caffeine affect individuals differently, a phenomenon driven by genetics, metabolism, and several other factors beyond mere intake.

Over 80% of US adults consume caffeine daily, yet many eventually question why they feel like caffeine doesn't affect me anymore. This common experience can be attributed to several factors, from building a physiological tolerance to genetic predispositions and accumulated sleep debt.

According to research, the human body's ability to process caffeine can vary up to 12-fold, suggesting a wide spectrum of individual tolerance. This significant variation explains why some people can consume a large espresso before bed without issue, while others get jittery from a single cup of tea. So, can some people handle more caffeine than others? The answer is a definitive yes, and it lies primarily in our genes and lifestyle.

According to genetic studies, approximately half the population carries a gene variant that causes them to metabolize caffeine more slowly, profoundly affecting their tolerance. So, can people be naturally tolerant to caffeine? The answer lies in your individual genetic makeup, which dictates how your body processes and responds to the stimulant from the very first sip.

According to a study published in the journal *Psychopharmacology*, approximately 10–20% of the population experiences heightened sensitivity to caffeine. This heightened reaction, leading to jitters and anxiety, can be caused by genetic variations and differences in how the body processes the stimulant.

While it's often assumed that caffeine affects everyone equally, scientific research shows that a person's metabolism speed, or how fast their body processes caffeine, varies widely. Many factors, including genetics, liver health, and lifestyle, can influence how long the stimulant effects last.

According to a study published in the journal *Psychopharmacology*, approximately 10-20% of the population experiences heightened sensitivity to caffeine. For these individuals, consuming even a small amount of caffeine can trigger adverse effects such as anxiety, restlessness, and a racing heart. Understanding the factors behind this sensitivity is key to managing its impact effectively.
