The body recovers very quickly after quitting cigarettes. But some changes remain irreversible.
Twenty minutes after stopping smoking, blood pressure is normalized. Nicotine in cigarettes releases epinephrine and norepinephrine, which increase heart rhythm and narrow blood vessels as these substances are usually cold.
After two hours, the need for nicotine returns and people become nervous and anxious. After eight hours, the carbon monoxide in the blood is eliminated, leaving the oxygen level to return to normal. For red smokers, red blood cells grow in size and ultimately cause blood clots, informs descopera.ro.
Twenty-four hours after cessation of cigarettes, a strong cough appears to try to get rid of all the toxins in the lungs. At the same time, the risk of heart disease decreases.
Within 48 hours nicotine is completely removed from the body and people start to feel the taste again. At 72 hours, the desire for nicotine will cause headaches, dizziness, nausea and cramps.
