My favourite coffee fact: all types of coffee are a laxative, both regular and decaf. However, we don't know what molecules in the coffee are responsible!

Caffeine isn't beneficial or negative in the long term.

  • It stimulates the central nervous system.

  • It releases free fatty acids from adipose (fatty) tissue.

  • It affects the kidneys, increasing urination, which can lead to dehydration.

  • Genetic variation for caffeine tolerance has an oversized effect on population studies.

Despite what popular press loves to talk about, any observable effect is minuscule, complicated and multivariable and you only have to wait a week to find a differing result.

For comparison, taking 1/4 of an aspirin tablet a day has been proven to extend the lives of a small group of humans (potential heart attack, age 40-65), but have zero effect on the majority.

> other stimulants like...

All stimulants, caffeine included, increase heart rate (HR) and blood pressure (BP).

Mostly your caffeine intake is low. A bottle of Coke only has 35ish mg of caffeine.

It is a very quick Google to find examples of sensitive people developing acute heart problems due to excessive caffeine intake.
