For decades, parents have blamed sweets for turning kids into little whirlwinds—but sugar doesn’t actually cause hyperactivity. The “sugar rush” is more myth than fact.

The idea started in the 1970s with one flawed study. Later research showed no solid link between sugar and hyper behavior. Instead, expectation plays a big role—if you believe sugar makes kids hyper, you’re more likely to notice every burst of energy.

And let’s be honest: kids eat sugar at parties, holidays, and special events—times when they’re already excited. The sugar’s just tagging along.

Sugar can give a quick energy boost, but it’s not the chaos-inducing fuel it’s been made out to be. More often than not, the hype comes from the party—not the pastry.
