Yes. Caffeine in energy drinks can disrupt a child’s sleep, contribute to anxiety, and raise heart rate or cause palpitations. These effects are possible, not inevitable, and vary by child. Pediatric guidance advises children and adolescents to avoid energy drinks; no research-based safe caffeine intake has been established for children.
How energy drinks can affect children
Energy drinks contain caffeine and may contain other stimulants. The FDA says too much caffeine in children and teens can cause increased heart rate, palpitations, high blood pressure, anxiety, sleep problems, digestive problems, and dehydration. The CDC also lists anxiety, insomnia, and heart complications among potential dangers of energy drinks.
These are potential effects, not a prediction that every child who drinks one will experience a medical problem. Responses vary with individual sensitivity, how quickly the body clears caffeine, the amount consumed, and health conditions. The FDA explains caffeine sensitivity and elimination differ from person to person: FDA guidance on caffeine.
Sleep
Caffeine can make it harder to fall asleep or disrupt sleep. The American Academy of Pediatrics’ parent guide says caffeine can remain in the body for more than eight hours, depending on metabolism. That does not establish a universal cutoff time: sensitivity and caffeine clearance vary. See AAP HealthyChildren.org’s guide to caffeine and children.

Anxiety
Too much caffeine can cause anxiety. The AAP’s clinical report also notes that caffeine can increase anxiety in people who have anxiety disorders. A child’s response is individual; the possibility does not mean every child will become anxious after consuming caffeine.
Heart rate and rhythm
Caffeine may increase heart rate and cause palpitations. The AAP clinical report describes caffeine as a potential trigger for arrhythmias, or abnormal heart rhythms; it does not mean an arrhythmia is inevitable after an energy drink. Children with heart or lung conditions may be especially sensitive to caffeine’s stimulant effects, according to the AAP parent guide. For an individual concern or an existing condition, ask the child’s clinician for advice.

What pediatric guidance says about caffeine
The CDC’s school nutrition guidance, dated July 22, 2024, reports the AAP recommendation that adolescents avoid energy drinks and consume no more than 100 mg of caffeine per day. That figure is guidance for adolescents, not proof of a universally safe dose for every child. CDC’s school nutrition standards page provides the recommendation and beverage context.
The CDC National Center for Health Statistics says research-based safe caffeine intake guidelines have not been established for children, and notes that caffeine may disrupt sleep. Read its data briefs for its youth caffeine discussion. In other words, do not treat 100 mg as a demonstrated safety threshold that applies to every child, or as an allowance for energy drinks.

The AAP’s detailed clinical report, Sports Drinks and Energy Drinks for Children and Adolescents, was published in 2011 and marked retired in July 2021. It explains caffeine effects and the distinction between drink types; current consumer guidance from the CDC and FDA should also be considered.
Energy drinks, sports drinks, and water are different
| Drink | What it is | What to know for children |
|---|---|---|
| Energy drink | Contains caffeine and may contain other stimulants. | Pediatric guidance advises children and adolescents to avoid these drinks. |
| Sports drink | A beverage intended for use in some prolonged, vigorous activity contexts; it is not an energy drink. | It is not a routine substitute for water. The AAP clinical report discusses the distinction between sports and energy drinks. |
| Water | A non-caffeinated drink for hydration. | Suitable for routine hydration; CDC includes water among healthy school beverage options. |
For the distinction and school beverage guidance, see the AAP clinical report and CDC school nutrition standards.

How to check a drink’s caffeine content
- Read the serving size. Check how many servings the container says it contains; a container’s total can differ from the amount listed per serving.
- Find the caffeine amount. Check the label for caffeine information and determine whether it applies per serving or to the whole container. Caffeine content varies by product.
- Consider other caffeine sources and the child’s circumstances. Sensitivity and caffeine elimination differ, and a heart or lung condition may increase sensitivity. A label amount alone cannot predict an individual response.
The FDA notes that it does not regulate products under a separate category specifically called “energy drinks”; products may be regulated according to their classification. Its consumer guidance also explains that caffeine content and individual responses vary.
When to ask a clinician
Contact the child’s clinician for individualized advice if the child has a heart or lung condition, an anxiety disorder, or another health concern that may affect their response to caffeine. The sources cited here describe possible effects and general guidance; they do not provide a diagnosis or a treatment protocol for a particular child.
