If you want to stay away from cardiovascular disease, you should exercise weights moderately because it works better than running. A new study in the United States says that lifting an hour a week can reduce the risk of heart disease and stroke.
Researchers at Iowa State University in the United States analyzed exercise data from 13,000 adults and found that weightlifting reduced the prevalence of metabolic syndrome. Metabolic syndrome is a general term for symptoms such as hypertension, hyperglycemia, and dyslipidemia, which may lead to coronary heart disease, stroke, and diabetes. Data analysis showed that weekly exercise exercises such as weightlifting for less than an hour reduced the risk of metabolic syndrome by 29%, the risk of hypercholesterolemia by 32%, and the risk of heart attack and stroke by 40% to 70%.
Researchers say that the body’s muscles are a powerful device that burns heat, helping joints and bones to work, and also promoting metabolism. If you have a muscle, even if you do not have aerobic exercise, you can burn more calories, effectively prevent obesity, and have far-reaching benefits for your health. Li Dejun, an academic researcher and associate professor of athletics at Iowa State University, said: “People may think that resistance movements are not as easy to implement as aerobic exercise. In fact, only two sets of barbells are needed, less than five minutes. “Sit on the back, it can play a role.” Professor Li added: “The new study said that ‘weight lifting is not a requirement for us to go to the gym to practice, squatting in heavy shopping or digging holes in the yard, etc., because it is good, because Strengthening muscle strength by lifting heavy objects is the key.”
People falling in love do not know the pain
Love not only makes people feel good, but also has the effect of treating diseases. The latest US study found that falling in love helps improve health, including high blood pressure, pain and allergies.
Researchers at the University of West Virginia in the United States tested volunteer brain activity in love and found that love is the result of working together in 12 regions of the human brain. The first change in brain activity begins within one-fifth of the time after people are “hit” by their lover’s eyes. At this time, a large amount of chemicals such as dopamine, which is called to regulate emotional response, and oxytocin, which is called “hug hormone”, are rapidly generated in the body, causing trust and reducing anxiety and lowering blood pressure.
Researchers at Stanford University in the United States used brain scans to assess volunteer responses to pain. People watch photos and receive hot probes to stimulate their hands. The results showed that when the subjects saw photos of the loved ones, the self-reported pain was 40% less than the actual value, and they did not have such an effect when they saw acquaintance photos. Researchers say that seeing lover photos triggers dopamine production in the body, raising their pain threshold (the lowest value of stress response caused by pain stimuli), which is like a natural painkiller.
Happy childhood memories make lifelong healthy
According to a new study published in the international journal Health Psychology, having a good childhood memory can improve the physical and mental health of a lifetime and reduce the occurrence of various chronic diseases.
Dr. William J. Schopek, a researcher at the Department of Psychology at Michigan State University, and his team combed the data on two large studies, the National Middle-aged Development Survey and the Health and Retirement Study. The first study was on 7100. Participants in their 40s conducted a 18-year follow-up survey, and the second study conducted a six-year follow-up survey of 15,000 participants over the age of 50. The survey included: descriptions of childhood memories, feelings with parents, overall health status, chronic disease incidence, depression, anxiety status, etc. As a result, I found that I felt happy and happy in my childhood, especially when I grew up with parents who were close to my parents, and my body was healthier. The incidence of chronic diseases was low. Those who had received great support from my father rarely had symptoms of depression in the future.
Dr. Schopenk said that the results show that there is a strong correlation between good childhood memory and health, and the benefits that people can obtain include high quality of work, good interpersonal relationships, low medications, and low risk of depression. These good memories help to reduce stress on the one hand, and also encourage people to consciously maintain a healthy lifestyle.
Children who love to chat are smarter
Don’t worry about your child’s chatter. A new study published in the American Journal of Neuroscience confirms that chatting with adults in early childhood can enhance brain language zone connections, improve language skills, and enhance social skills. Such children are smarter.
Researchers at the Massachusetts Institute of Technology, Harvard University, and the University of Pennsylvania conducted a comparative survey of more than 40 children aged 4-6 years in Boston, including parent-child activities, language development, academic performance, and brain scans. The key to development is not the vocabulary, but the way parents communicate with their children. The more frequently you talk to your parents, the more active the language area in your child’s brain. Research director Dr. Rachel Romeo said that adults often chat with young children to enhance the connection strength of white matter fibers in the two key language regions of the brain.
