(HealthDay News) -- Caffeine is much more than a wake-me-up among coffee drinkers. The chemical stimulant also is found in everything from popular sodas to over-the-counter pain relievers and cold remedies.
The Nemours Foundation says caffeine may trigger these symptoms in children:
- Feeling nervous and jittery.
- An upset stomach.
- Trouble concentrating and sleeping.
- Showing a spike in heart rate and blood pressure.
