📰 Body fat predicts major health risk that BMI misses, researchers say
A new study from the University of Florida challenges the accuracy of using Body Mass Index (BMI) as a predictor of mortality risk. The study suggests that measuring body fat percentage is a more reliable indicator of health outcomes. Over a 15-year period, individuals with high body fat levels were found to have a significantly higher risk of death, particularly from heart disease. The study involved 4,252 participants in the U.S. and utilized bioelectrical impedance analysis to measure body fat. The limitations of BMI, such as its inability to differentiate between muscle and fat mass, were highlighted by the researchers.
📰 Extreme heat affects the brain — here’s how to protect your cognitive health
The article discusses the impact of extreme heat on mental health, highlighting how hot weather can affect the brain and lead to symptoms like irritability, anxiety, and memory issues. Dr. Jace Reed from Cedars-Sinai Hospital emphasized the importance of recognizing early signs of heat affecting mental abilities, as it could progress to heat stroke. Thea Gallagher from NYU Langone Health explained how overheating can disrupt internal balance, impair cognitive function, and increase inflammation in the brain, potentially worsening existing neurological conditions. Higher temperatures can weaken the blood-brain barrier, making the brain more vulnerable to toxins and pathogens, and can also lead to disturbances in mood and behavior. The article also mentions that people with mental health conditions are more susceptible to the negative effects of hot weather, and certain psychiatric medications can impact the body’s ability to regulate temperature. To protect brain health during extreme heat, experts recommend prioritizing sleep, rest, and finding ways to slow down.
📰 CDC committee moves to phase out controversial mercury ingredient from flu vaccines
The article discusses the inclusion of thimerosal, a mercury-based preservative used in vaccines, on the agenda for a meeting of the CDC’s Advisory Committee on Immunization Practices. Thimerosal has been used since the 1930s to prevent contamination in multi-dose vaccines and medications. In 2001, thimerosal was removed from vaccines recommended for children 6 and younger, except for influenza vaccines. The CDC’s Advisory Committee on Immunization Practices recommended that all adults and children should receive seasonal influenza vaccines without thimerosal. Despite concerns about mercury exposure, health agencies claim there is no evidence of harm from thimerosal in vaccines.
📰 Disposable vapes more toxic and carcinogenic than cigarettes, study shows
A study from the University of California (UC) Davis revealed that illegal disposable e-cigarettes, or vapes, may pose a greater health risk than traditional cigarettes due to high levels of toxic heavy metals. The research focused on three popular vape brands not authorized by the FDA for use in the U.S. and found hazardous levels of lead, nickel, and antimony, which are known carcinogens. The study’s senior author, Brett Poulin, expressed shock at the toxic metal concentrations, with one brand exposing users to as much lead as smoking 19 packs of cigarettes. The study also highlighted the need for stricter regulations on disposable vapes and clearer health risk warnings on packaging, especially for young users. While the study had limitations in testing only three brands, it emphasized the urgent public health concern posed by the widespread popularity of these potentially harmful devices.
📰 Heart attack deaths have plummeted in US, but new cardiovascular threats emerge
The American Heart Association’s study revealed a significant decline in heart attack deaths by almost 90%, while other types of cardiovascular diseases like heart failure, arrhythmias, and hypertensive heart disease are on the rise. In 1970, heart attacks accounted for over half of all heart disease deaths, but by 2022, their share had decreased to 29%. The study highlighted the importance of advancements in managing heart attacks and other heart conditions over the past 50 years. Researchers emphasized the need to address emerging challenges posed by the increasing deaths from heart failure and arrhythmias. Despite progress, risk factors like obesity, type 2 diabetes, hypertension, and physical inactivity continue to fuel heart disease cases, emphasizing the ongoing battle against heart disease.
