How much exercise a day to you get? Why do you think exercise helps the heart? The heart is a muscle and just like other muscles in our body, it is weaker if we don’t use it. Exercise helps keep the heart stronger.
Can you think of a case where exercise is not good for you? Sometimes people have heart issues and exercise can cause damage. Young people playing sports often don’t realize that there is an issue. It is always important for young athletes to listen to how your body feels and to let others know when they feel bad during practice.
What happens to your heart and body when you exercise? The heart beats faster – it does this to bring more oxygen ans nutrients to our hard-working muscles. We breathe faster and deeper to bring in more oxygen, as well. The muscles are making energy burning the fat and carbohydrates from our diet. All this energy we make, causes us to get hot and sweat!
How many hours of sleep do you get at night? Why is sleep important for the heart? Our body and out heart need rest. During sleep, we are lying down and our heart doesn’t work as hard.. It is recommended that school age kids get 9-11 hours and teens get 8–10 hours sleep a night.
