On a cellular level, how does exercise make us healthy or improve our health?
In: Biology
On a cellular level, you grow new muscle cells- not just obvious ones like in the arms and legs, but in the heart as well.
A stronger heart doesn’t have to work as hard when you’re at rest.
Exercise also reduces fat deposits on important organs like the liver and heart, which can make them not work as well if those deposits get too big.
And finally exercise makes your body release chemicals which improve your mood and help you sleep more regularly.
