A new study, performed by the researchers from Chicago, finds that hookah smoking may impair the endothelial function of blood vessels. Therefore, it may harm your cardiovascular health.
For the study, a team of scientists examined 30 young healthy adults before and after hookah smoking. The average age of participants was 26 years. The scientists compared the received results with the effects of one normal cigarette in people of the same age.
Study leader Mary Rezk-Hanna, Ph.D., an assistant professor at the University of California, Los Angeles School of Nursing, says: “Hookah is the only form of tobacco product that uses burning charcoal briquettes to heat the flavored tobacco in the water pipe. So, in addition to toxic substances from tobacco and nicotine, hookah smoke exposes users to charcoal combustion products, including large amounts of carbon monoxide.”
A new study from the Netherlands finds that smoking and diabetes are linked to the calcium buildup in the hippocampus, a part of the brain which is important for memory.
Within the tasks of the study, a team of scientists examined the multiplanar brain CT scans of approximately 2,000 people who attended a hospital memory clinic in the Netherlands between 2009 and 2015. The patients’ average age was 78, ranging from 45 to 96 years.
Having analyzed the received CT scans, the researchers concluded that 19% of the study participants had calcification in the hippocampus. Also, the older age, smoking, and diabetes were associated with the higher level of calcifications in the brain.
Lead study author Dr. Esther J. M. de Brouwer, from the Department of Geriatrics at the University Medical Center in Utrecht, says: “It is […] likely that smoking and diabetes are risk factors for hippocampal calcifications.”
According to a team of scientists from the University of Rochester, vaping flavors such as vanilla and cinnamon are toxic to leukocytes, or white blood cells, increasing the risk of developing life-threatening diseases.
For the study, the researchers exposed immune cells to chemicals used in e-cigarette flavoring. They discovered that this type of cells produced substances responsible for inflammation and tissue damage. In addition, many of the flavoring chemicals caused a significant level of the death of these cells.
Senior author Dr. Irfan Rahman, of the environmental health sciences center, says: “While e-cigarettes are thought to have relatively less or no harm to the consumer’s health compared to tobacco smoke, vaping flavors are not safe for inhalation. Currently, these are not regulated, and alluring flavor names, such as candy, cake, cinnamon roll and mystery mix, attract young vapers.”
New research has confirmed that exercise can help smokers finally kick the habit.
Experts at St George’s University of London, have examined the mechanism that makes exercise to protect the body against nicotine dependence. The study has shown that even moderate intensity exercise can significatly reduce nicotine withdrawal symptoms.
Also researhes revealed the incrased activation of one of the receptors in brain named α7 nicotinic acetylcholine, which is a target of nicotine.
Dr Alexis Bailey, Senior Lecturer in Neuropharmacology, at St George’s, University of London, said: “The evidence suggests that exercise decreases nicotine withdrawal symptoms in humans; however, the mechanisms mediating this effect are unclear.
“Our research has shed light on how the protective effect of exercise against nicotine dependence actually works.”
A new research, published in the European Respiratory Journal, finds a diet rich in tomatoes may restore lung function in people who quit smoking and slow down lung function decline and all people.
In the course of the study, the scientists found that those adults who ate more than three portions of fruit or more than two tomatoes experience slower lung function decline than those who consumed fewer than one serving of fruit or one tomato a day.
The lead study author Vanessa Garcia-Larsen, an assistant professor in the Bloomberg School’s Department of International Health, says: “This study shows that diet might help repair lung damage in people who have stopped smoking. It also suggests that a diet rich in fruits can slow down the lung’s natural aging process even if you have never smoked.”
