Answer:
- blood oxygen levels returned to normal
- better cardiovascular circulation
- easier breathing and respiration
- improved oral and skin health
Step-by-step explanation:
According to WHO (World Health Organization), smoking, one of the leading causes of preventable death in the world, kills more than five million people a year.
Although 70% of smokers are interested in quitting, only 3% succeed without professional help. However, quitting smoking with or without professional help is extremely important because it has many health benefits and the result is immediate.
Twenty minutes after smoking, blood pressure and pulse rate return to normal. Two hours later, there is no nicotine in the blood. Eight hours later the blood oxygen level normalizes. Two days later your sense of smell and taste improve, the health of your mouth gets better and your skin begins to improve as well. After three weeks breathing becomes easier and cardiovascular circulation improves significantly. After one year, the risk of coronary heart disease is halved and the benefits only increase.
