Caffeine is a stimulant.
SYMPTOMS
In moderate doses, it can:
- Increase alertness
- Reduce fine motor coordination
- Cause insomnia
- Cause headaches, nervousness and dizziness
It has also been known to result in:
- Anxiety
- Irritability
- Rapid heartbeat
- Excessive urination
- Sleep disturbance
- A "caffeine crash" once the effects wear off
If the conditions listed under "symptoms" occur, discontinue the use of caffeine. These effects are more likely to occur if caffeine is consumed in large doses. Children and women who are nursing or pregnant should avoid caffeine. People who are taking any prescription medication should talk to their doctors before consuming caffeine.
Knowing the caffeine content of your food and drinks can help you keep caffeine intake at a healthy level so you can still reap the benefits of a good night's sleep.
