A new study, recently published in the European Journal of Preventive Cardiology, suggests that exposure to blue light may help reduce high blood pressure.
For the study, a team of researchers assessed whether blue light exposure could produce enough nitric oxide to significantly reduce high blood pressure. They involved 14 male participants aged between 30 and 60 years without a previous diagnosis of cardiovascular conditions.
The authors of the study come into a conclusion: “Our present study demonstrates for the first time that whole-body blue light exposure at doses that are comparable to daily sunlight exposure decreases systolic blood pressure […] in young, healthy male volunteers.”
Recent British research, presented at the National Cancer Research Institute annual conference in the UK, suggests that women who are early risers have lower chances to develop breast cancer.
To study the link between sleep habits and breast cancer, researchers analyzed two data banks with more than 409,000 women. The scientists concluded that early risers had a 40% lower risk of developing breast cancer compared to night owls.
Rebecca Richmond, a research fellow in the Cancer Research U.K. Integrative Cancer Epidemiology Program at the University of Bristol, says: “We would like to do further work to investigate the mechanisms underpinning these results, as the estimates obtained are based on questions related to morning or evening preference, rather than actually whether people get up earlier or later in the day.”
A new study from Iowa State University, US, suggests that singing may have certain benefits for people suffering from Parkinson’s disease. These benefits include improving motor function and a reduction of stress.
For the study, the researchers measured heart rate, blood pressure and cortisol levels in 17 participants with the condition before the one-hour singing session.
Study leader Elizabeth Stegemöller, an assistant professor of kinesiology, explains: “We see the improvement every week when they leave a singing group. It’s almost like they have a little pep in their step. We know they’re feeling better and their mood is elevated. Some of the symptoms that are improving, such as finger tapping and the gait, don’t always readily respond to medication, but with singing, they’re improving.”
According to a new study, insufficient sleep is associated with dehydration due to the disrupted release of a hormone responsible for hydration regulation.
For their research, a team of researchers analyzed the data from over 20,000 records of healthy young adults who participated in two big studies, the National Health and Nutrition Survey and the Chinese Kailuan Study.
The scientists concluded that people who slept for 6 hours or less on a regular basis were 16-59% more likely to experience dehydration than people who slept for at least 8 hours every night.
Asher Rosinger, Ph.D., an assistant professor of biobehavioral health at Pennsylvania State University in State College, explains: “This study suggests that if you’re not getting enough sleep and you feel bad or tired the next day, drink extra water.”
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.”
