A new study from Columbia University and an international team of researchers identifies multiple ways to achieve the same health benefits from exercise-as long as the exercise “cocktail” includes plenty of light physical activity.
“For decades, we’ve been telling people that the way to stay healthy is to get at least 30 minutes of exercise five days a week,” says Keith Diaz, PhD, assistant professor of behavioral medicine and director of the exercise testing laboratory at the Center for Behavioral Cardiovascular Health at Columbia University Vagelos College of Physicians and Surgeons.
“But even if you’re one of the few adults who can stick to this advice, 30 minutes represents just 2% of your entire day,” says Diaz. “Is it really possible that our activity habits for just 2% of the day is all that matters when it comes to health?”
Intimidation of Brazil’s enviro scientists, academics, officials on upswing
Increasingly, Brazilian environmental researchers, academics and officials appear to be coming under fire for their scientific work or views, sometimes from the Jair Bolsonaro government, but also from anonymous Bolsonaro supporters.
Researchers and academics have come under attack for their scientific work on agrochemicals, deforestation and other topics, as well as for their socio-environmental views. Attacks have taken the form of anonymous insults and death threats, gag orders, equipment thefts, and even attempted kidnapping.
A range of intimidation is being experienced by officials, including firings and threats of retaliation for institutional criticism at IBAMA, Brazil’s environment agency, ICMBio, the Chico Mendes Institute of Biodiversity Conservation overseeing Brazil’s national parks, and FUNAI, the Indigenous affairs agency.
