Smoking could lower immunity and increase the risk of being exposed to Covid-19, with more acute symptoms experienced as compared to non-smokers, University of North Sumatra lecturer Dr. Delyuzar Ked said.
He added, “Smoking can also reduce the movement of vibrating hairs (or cilia) in the respiratory tract, thereby raising susceptibility to chronic infections. Hence, if you are infected with Covid-19, you will be susceptible to respiratory tissue disorders, with more severe symptoms.”
He cautioned smoking disrupts blood vessels and increases the risk of their narrowing that can hinder heart functioning or cause coronary artery disorders.
Other blood vessel disorders could cause heart attacks, or narrowing of the heart muscle tissue called a myocardial infarction.
The World Health Organization estimates that by 2030, some 70 percent of deaths caused by smoking will occur in developing countries, including Indonesia.
