Holiday heart syndrome

Okay, kiddo! You know how sometimes grown-ups like to drink alcohol during the holidays? Well, that can sometimes cause a problem called "holiday heart syndrome."

See, alcohol is a type of drink that can make your heart beat faster and harder than usual. If a grown-up drinks too much alcohol too often, their heart can get tired and start to beat irregularly.

When that happens, it's called "holiday heart syndrome" because it often happens during times of year when people tend to drink more, like Christmas or New Year's Eve.

It's not good for a grown-up's heart to keep beating irregularly like that, so they might need to see a doctor to make it stop. And to avoid getting holiday heart syndrome in the first place, grown-ups should try to drink alcohol in moderation and drink lots of water too to stay hydrated.

Does that make sense, kiddo?
