Not as a rule: Headache is a symptom and not a disease. You must establish the cause, caffeins sometimes help at least temporalily.

Sometimes: Caffeine sometimes helps headaches and there is caffeine in many headache pills. However too much caffeine can worsen headaches, and if it interferes with sleep that can also worsen headaches.

No: Caffeine helps prevent dementia in the long run, excessive caffeine is not good - if you are vit B6 deficient the caffeine breaksdown in body to homocysteine which increases inflammation, so either you can increase your vit B6 intake or make up for caffeine by drinking 3 times the oz in water. Theophylline in tea is a stimulant people with irregular heartbeat need to watch the amount they drink..

No: Caffeine addiction is like any other addiction. Too much can cause health problems and cutting back is difficult. But you can do it over time - just substitute something else instead like water, a healthy snack (e.g. Banana), or unsweetened juice. If you do cut back too fast, you may get headaches, anxiety, nausea, or other withdrawal symptoms.

Dr. Keegan Duchicela

Stimulant: Caffeine's effects often depend on the individual. For some people, it can provide energy, focus, and alertness. In others, and especially at higher concentrations, it can cause jitteriness, problems sleeping, and palpitations. With repetitive use, you may become tolerant to caffeine, meaning its effects are reduced over time.
