Scientists Explain Why Caffeine Affects People Differently
Genetics, lifestyle and caffeine habits combine to determine how strongly a person reacts to caffeine, according to scientists cited by BBC Health.
Scientists say the varying effects of caffeine on different people come down to a combination of factors, including personal habits, lifestyle and genetics, according to a report by BBC Health.
The report notes that while some people can drink coffee late in the day without disruption to their sleep, others feel a strong "buzz" or experience jitteriness from even a small amount of caffeine.
According to the scientists cited in the report, one's caffeine tolerance is shaped in part by regular consumption habits and overall lifestyle. However, they also point to genetics as a significant factor that individuals cannot control, suggesting that inherited traits play a role in how the body processes caffeine.
The BBC Health report does not detail specific genes or studies involved, but frames the differing reactions to caffeine as a subject of ongoing scientific interest.
