Additionally, young adults with mild hypertension who consume over four cups of coffee daily face a fourfold increase in heart attack risk compared to those who consume two cups or less.


Caffeine has addictive properties that can lead to dependency. Regular consumption builds tolerance, requiring higher doses for the same effect. Abrupt cessation may cause withdrawal symptoms like headaches, fatigue, and irritability. While milder than other addictions, caffeine addiction should be approached with caution.
