Health

The human body is doing extraordinary things right now without asking for permission. Bones are quietly repairing microscopic damage. Adenosine is building up in the brain, measuring how long you have been awake. Rod cells at the back of your eyes are adjusting to the light in the room.

Smile with Daniel explores health and the human body through questions children actually ask. Why do our feet fall asleep? Does being cold actually make you sick? How do painkillers know where the pain is? Why does coffee make you feel awake, and what is actually happening when the effect wears off?

The answers are almost always more interesting than the common explanation, and more honest about what scientists know, what they are still working out, and where the evidence is genuinely uncertain.

Here you’ll find every Smile with Daniel episode about health and the human body, approachable enough for a curious eight-year-old, accurate enough to satisfy the adult listening alongside them.
