Mr. Xiao, 55, has always maintained a fitness routine, squeezing in workouts on gym equipment even during his busiest workdays. Lately, however, he's been yawning constantly during exercise. His wife found this odd and urged him to see a doctor, but he refused: "I'm just a bit tired—why go to the hospital for nothing?"
In fact, researchers from the State University of New York in the U.S. have found that yawning helps replenish oxygen in the blood and cools the brain. However, they caution that persistent yawning during exercise may indicate a malfunction in the body's "cooling mechanism," potentially signaling an issue with the heart or circulatory system.
Historically, we've focused heavily on how factors like weight and blood pressure harm heart health, yet overlooked the "signals" of heart disease risk hidden in everyday details.
These two lifestyle details may also hint at heart disease
Bad breath, while seemingly insignificant in daily life, can make social interactions unpleasant when experienced with someone else.But did you know? Persistent bad breath may indicate issues beyond oral health. A study published in the American Journal of Preventive Medicine suggests halitosis could signal heart problems. Why? Researchers explain that gum disease allows bacteria to proliferate in the mouth, potentially triggering heart disease. Therefore, the study concludes that treating gum disease—including halitosis—can actually reduce the risk of heart disease.
Additionally, many people experience orthostatic hypotension, feeling dizzy when standing up suddenly. Experts caution that while this symptom typically lasts only 1-2 seconds for most individuals, if it persists for several minutes, it may indicate underlying circulatory issues—particularly concerning for those under 55.A U.S. study found that individuals with a long history of dizziness have a 50% higher likelihood of developing heart failure compared to the general population.
These two foods can effectively reduce the risk of heart disease
Modern people are increasingly focused on heart health, especially as they enter middle age. So, which foods can help maintain better heart health? Pan Danfeng, Associate Chief Physician of the Nutrition Department at Guangzhou First People's Hospital, stated on the Family Doctor Online "Health 100,000 Why" Q&A platform that vegetables and fruits can effectively lower the risk of heart disease.
According to Dr. Pan, a Harvard University study demonstrated that each additional serving of vegetables or fruit reduces the risk of coronary atherosclerotic heart disease by 4%. Specifically, each additional serving of leafy greens and cruciferous vegetables lowers the risk of coronary atherosclerotic heart disease by 30% and 24% respectively in women.
Furthermore, fresh vegetables and fruits are widely recognized as the best foods for cancer prevention. After reviewing professional research materials from around the world, the American Institute for Cancer Research concluded that there is sufficient evidence indicating vegetables and fruits can reduce the risk of lung cancer and digestive tract tumors, and may also lower the risk of breast cancer, uterine cancer, bladder cancer, and others.
Thus, due to their unique nutritional composition and diverse phytochemicals, vegetables and fruits serve as natural foods that maintain normal intestinal function, enhance immunity, and prevent various lifestyle-related diseases including cardiovascular disease, cancer, obesity, and constipation. Consequently, dietary guidelines worldwide have increasingly emphasized expanding the variety and quantity of vegetable and fruit consumption in recent years.
