Have you ever breathed in and out really quickly for a little bit and gotten dizzy? That's because all the tiny breaths are pulling in the oxygen too quickly for your lungs and blood to grab hold of it and forcing it back out again, meaning that, as a result, your brain isn't getting enough oxygen, and that's what makes you dizzy. When you smoke, you're breathing in chemicals that bond with the hemoglobin in your blood better than oxygen does. When you breathe in, those chemicals bond with your blood and go through your stream instead of oxygen, meaning your body isn't getting enough, including your brain. That's why you get dizzy.
Your body is trying to tell u - DO NOT SMOKE!! I am 58 years old and finally was able to quit. It has probably been the hardest thing I have EVER DONE!! Please listen,...not trying to tell u what to do, but,...stop now! Take my word, it is not worth it!! I promise!!
The good news is that's the high you get from cigarettes. The BAD news is that you stop getting that high after a couple days of smoking and all your left with is a dirty habit.
Because there are chemicals in cigarettes that can make you sick.
why do you feel tired after running a marathon?
