As a new school year begins, tired teenagers may reach for coffee, soda or energy drinks to stay awake through early classes, homework and extracurricular activities. Caffeine is increasingly easy for teens to find, with energy drinks and highly caffeinated beverages marketed as quick ways to improve alertness and performance.
The problem is that caffeine doesn’t actually create new energy. It works by blocking the effects of a chemical that makes the body feel sleepy, temporarily masking fatigue rather than replacing the sleep a growing teenager needs.
For parents, the concern extends beyond coffee. Caffeine can also be found in tea, chocolate, soda, energy drinks and some supplements, making it easy for a teenager’s daily intake to add up.
How Caffeine Affects Kids and Teens
Caffeine can cause jitteriness, nervousness, irritability, headaches, increased heart rate and difficulty sleeping. Those effects can be particularly problematic for teenagers, who are still developing physically and mentally.
The American Academy of Pediatrics recommends that adolescents ages 12 to 18 consume no more than 100 milligrams of caffeine per day. Some energy drinks contain two or three times that amount in a single serving, making it surprisingly easy for teens to exceed that recommendation.
Sleep may be one of the biggest concerns. Too much caffeine can contribute to insomnia, daytime fatigue and difficulty concentrating, potentially creating a cycle in which a tired teenager consumes even more caffeine the following day.
Healthier Ways to Boost Teen Energy
Parents can encourage teenagers to look beyond caffeine when they need an afternoon energy boost. Drinking water, eating nutrient-dense foods, getting outside and moving around can all help combat tiredness without adding another stimulant to the day.
GoodRx recommends several caffeine-free strategies, including physical activity, hydration, nutritious meals, sunlight and short naps. Even a brief walk can help reduce fatigue, while a 15- to 30-minute nap may improve alertness without the potential downsides of another energy drink.
Most importantly, parents should emphasize sleep as the foundation of healthy energy. GoodRx notes that better sleep habits can help teenagers feel more awake during the day, making caffeine less necessary in the first place.
