How does exercise effect blood sugar?
When you exercise, your body needs extra energy from blood sugar, also called glucose.
When you do something quickly, like a sprint to catch the bus, your muscles and liver release glucose for fuel.
The big payoff comes when you do moderate exercise for a longer time, like a hike. Your muscles take up much more glucose when you do that. This helps lower your blood sugar levels.
If you’re doing intense exercise, your blood sugar levels may rise, temporarily, after you stop.
