Answer:
1) how does physical activity help improve sleep quality?
Answer: Exercising also improves sleep for many people. Specifically, moderate-to-vigorous exercise can increase sleep quality for adults by reducing sleep onset – or the time it takes to fall asleep – and decrease the amount of time they lie awake in bed during the night.
2) how does physical activity help reduce the risk of a heart attack?
Answer: When it's exercised, the heart can pump more blood through the body and continue working at optimal efficiency with little strain. This will likely help it to stay healthy longer. Regular exercise also helps to keep arteries and other blood vessels flexible, ensuring good blood flow and normal blood pressure.
