When I was in A&P, my instructor, the dept chair said over and over:
and that doing these things would improve your health, and reduce symptoms of acute/chronic conditions.
At first we thought she was kidding, but she has the right idea.
Do small steps:
Eat more fruits/vegetables. Will help boost your immune system, fill you up, and help you to eat less, so you can
Lose weight, one I struggle with....
and exercise more, also boosts your immune system.
I've started to exercise, and I feel less hungry, am eating less, have more energy, and am sleeping less (as in being so tired I need a nap...)
If you smoke, my heart goes out to you. I'm an ex smoker, and this is one tough habit to break...
If these dont fit into your lifestyle, think of some that do, they dont have to be big huge changes, just little ones to help boost your body's reserves.
Hope this helps!!
