Do psychedelics really work to treat depression and PTSD? Here’s what the evidence says

Early results from studies around the world have found psychedelic therapy might be effective for treating a range of psychological issues. However, as psychedelic research has grown, limitations of the research have been identified by researchers both within and outside the psychedelic field. One issue is that we aren’t sure whether findings might be due to a placebo effect, which occurs when a treatment works because people expect it to work.

BMI alone will no longer be treated as the go-to measure for weight management – an UW obesity expert explains

Ultimately, BMI cannot provide doctors with precise information about the portion of body weight composed of body fat, nor can it tell us how that fat is distributed in the body. But this distribution is important because research has shown that fat stored around the internal organs has significantly higher health risks than that distributed in the extremities

Saving lives from extreme heat: Lessons from the deadly 2021 Pacific Northwest heat wave

The 2021 heat dome was Washington’s deadliest weather disaster on record. It contributed to 441 deaths in the state between June 27 and July 3, our research shows. Medical systems were overwhelmed. There are numerous ways to avoid this deadly of an outcome in the future. Many emerge from thinking about extreme heat as long-term risk reduction, not just short-term emergency response.

Hair

Big hair? Bald? How much difference your hair really makes to keep you cool or warm

When humans moved from living in the jungle to the savannah, they needed to walk and run long distances in the sun. This meant they needed a way to handle the increased body temperature that comes with physical activity in the heat.

Sweating is the best way to lose heat and cool down, but the presence of hair reduces sweating and heat loss from the skin. So humans evolved to lose body hair to be better adapted to exercising in the heat. Fewer hair follicles in our skin made room for more sweat glands. This made our skin optimal for sweat evaporation – and the heat loss that goes with it – to keep us cool.

Climate Crisis Is on Track to Push One-Third of Humanity Out of Its Most Livable Environment

Climate change is remapping where humans can exist on the planet. As optimum conditions shift away from the equator and toward the poles, more than 600 million people have already been stranded outside of a crucial environmental niche that scientists say best supports life. By late this century 3 to 6 billion people, or between a third and a half of humanity, could be trapped outside of that zone, facing extreme heat, food scarcity and higher death rates, unless emissions are sharply curtailed or mass migration is accommodated.
