Body size, medications, pregnancy, liver function, smoking status, and habitual caffeine use can also influence caffeine metabolism.
Moderate coffee consumption may be associated
with several benefits, but the same morning habit can also produce unwanted effects—especially if caffeine accumulates faster than your body can clear it.
12. Coffee Can Increase Anxiety in Sensitive People
Caffeine stimulates the central nervous system.
For people who are sensitive to it, too much may cause:
- Nervousness
- Restlessness
- Trembling
- Racing thoughts
- Palpitations
- A feeling of being “on edge”
People with anxiety disorders may find that large amounts of caffeine worsen symptoms.
If your morning coffee regularly leaves you jittery rather than comfortably alert, reducing the portion or switching
partly to decaf may help.
