In the lessons

In health and everyday life, everyone can be very active sometimes, but hyperactivity is when it happens a lot and makes school or home harder. ADHD is a real condition, not bad behaviour; children with it can get help and often have great strengths. In science, «hyperactivity» can also describe an organ or gland working too much. Myth: sugar causes hyperactivity — studies have mostly not found this.
