Exercise and being at high places both affect how our bodies handle oxygen and carbon dioxide.

When We Exercise:

• Our bodies need more oxygen, which makes our heart beat faster and we breathe more.
• More oxygen connects with hemoglobin in our blood, and we also produce more carbon dioxide because our bodies are working harder.

When We Are at High Altitudes:

• There is less oxygen available, which can make it hard to breathe (this is called hypoxia).
• To cope, our bodies start to breathe faster and will create more red blood cells over time.

In short, our bodies are amazing at adjusting. No matter if we're exercising or at a higher altitude, they make sure we get enough oxygen and remove carbon dioxide effectively. It's really cool to see how our bodies can adapt!
