(HealthDay News) -- Caffeine can provide a little "pick-me-up" if you're struggling to stay awake. But this common stimulant, found primarily in many coffees and teas, also can cause a number of unwanted side effects.
In addition to the jitters, the National Sleep Foundation mentions these potential side effects of caffeine:
-
Dizziness, nausea, headache and/or insomnia.
-
Anxiety or irritability.
-
Rapid heartbeat.
-
Reduction in fine motor coordination.
-
Urinating more than usual.
