Tag: Hyperactivity myth

According to extensive scientific research, the phenomenon known as a 'sugar rush' is largely a myth. Instead of a burst of hyperactive energy, consuming large amounts of sugar actually causes a rapid spike and subsequent crash in blood glucose levels, leading to feelings of fatigue and irritability. This article explores the scientific truth behind what it means to have a sugar rush and how it impacts your body.

According to a 2019 meta-analysis published in *Neuroscience & Biobehavioral Reviews*, sugar consumption was not found to improve mood and was actually linked to increased fatigue and decreased alertness in the first hour. Many people still ask how to describe a sugar rush, a phenomenon more tied to perception and the subsequent 'crash' rather than a true energy high.

Scientific evidence has largely debunked the notion of a "sugar rush" causing hyperactivity. The perceived energetic boost and subsequent crash are more about your body's metabolic response to glucose, which typically begins to rise within minutes of consumption and can peak around one hour later.
