On the occasion of World No Tobacco Day on 31. Experts from the German Lung Foundation point out that smoking not only harms the health of the individual, but also endangers the health of future generations – indirectly through epigenetic influences and directly through exposure to secondhand smoke. They cite the results of two recent studies. Epigenetic means that tobacco smoking leads to genetic changes that can be passed on to subsequent generations.

Epigenetic influences operate across three generations

As an international study published in European Respiratory Journal epigenetic changes caused by smoking can even have an effect over several generations (see European Respiratory Journal, online prepublication at 1.4.2021 ): First, from father to child: those who smoke before puberty may later, if they become fathers, affect their children's pulmonary function Lung function (by decreasing one-second capacity FEV1 and forced vital capacity FVC). Secondly, from paternal grandmother to child: women who smoke during pregnancy can cause both their sons and grandchildren to have poorer lung function ( FEV1 FEV1 The so-called FEV1 (= forced expiratory volume in one second) – which is the amount of air that the patient can exhale with all his strength and as quickly as possible within one second.

Secondhand smoke increases blood prere in children

Direct influences of passive smoking on the health of non-smokers are already well known: In particular, children exposed to tobacco smoke are more likely to suffer from chronic lung diseases such as chronic bronchitis, asthma, and recurrent pneumonia. A U.S. study from New York has now shown that children and adolescents exposed to tobacco smoke already have significantly higher blood prere levels (see JAMA Network Open, published online on 23.2.2021 ). However, the development of hypertension should be avoided at all costs, as it is known to cause u.a. the risk of heart attacks, strokes Strokes occur more frequently during the blood prere low around 3 a.m. (midnight stroke) or during the second blood prere low in the afternoon. The signs of disease usually start suddenly. Depend on the location of the infarct. First signs may be severe headache, pronounced clouding of consciousness or even unconsciousness. A mostly in the arm develops-. Facial area emphasized unilateral paralysis. Initially, the paralyzed side is flaccid (in the face z.B. as a hanging corner of the mouth and swelling of the cheek on the paralyzed side when exhaling ="tobacco blisters"), later uncontrolled twitching may also occur. Cerebral ischemic stroke is the result of either a thrombotic or embolic vessel occlusion (ischemic cerebral infarction) or a spontaneous vessel rupture with subsequent hemorrhage (hemorraghic cerebral infarction). Ischemic stroke: Cerebral infarction, which is caused by blood congestion due to clogged vessels and therefore leads to an undersupply of oxygen to brain cells. Ischemic cerebral infarction due to reduced blood flow in an endarterial area caused by sudden occlusion of the artery is the most frequent cause of stroke (80-85%).

Hemorraghic stroke: Calcified blood vessels in the brain rupture, leading to cerebral hemorrhage. This interrupts the blood supply and thus the oxygen supply to the brain cells affected or. quit and they die off.

and kidney disease is greatly increased.

Quitting smoking also improves mental health

"Quitting smoking will therefore not only benefit one's own health, but may also offer advantages for future generations," sums up Prof. Dr. Stefan Andreas, Member of the Advisory Board of the German Lung Foundation and Head of the Lung Clinic Immenhausen and the Pneumology Department Pneumology Respiratory and pulmonary medicine (pneumology) is a branch of internal medicine that deals with the prevention, detection and specialist treatment of diseases of the lungs, bronchi, mediastinum (middle pleura) and pleura (pleura of the ribs and lungs). at the University Medical Center Gottingen. The fear that quitting smoking could have negative effects on one's own psychological well-being and social life can also be debunked: according to a recent review study in the Cochrane Library according to the study, people have less depression, anxiety and stress after just six weeks of quitting smoking than people who continue to smoke (see Cochrane Library, online publication on 9.3.2021 ). "So if you stop smoking, you can also positively influence your mental health and achieve better overall mental and physical well-being in the long term," summarizes Prof. Andreas together.
