What The Government's Latest Asian-American Health Report Got Wrong
Asian-Americans fare better than the general population on five different measures of health, according to a new national study.
But though it may appear that the "model minority" myth about the 15 million Asians in America extends even to physical and mental health, experts say this finding obscures the truth about vast disparities between Asian subgroups -- and that the study's methodology may have prevented the elderly, immigrants and people who don't speak English from contributing to a more nuanced picture of the health status of Asians in America.
The report, published by the U.S. Center fo...

These 10 Cities Are Choking On The Planet's Worst Air Pollution
Urban air pollution is on the rise and, to little surprise, those living in some of the world's poorest cities are breathing in the worst of it.
The World Health Organization on Thursday released updated data showing more than 80 percent of city residents around the globe are exposed to particulate pollution in doses that exceed the organization's recommended limits.
"Urban air pollution continues to rise at an alarming rate, wreaking havoc on human health," Dr. Maria Neira, WHO's public health director, said in a statement.
WHO says that in the last two years, as more and more cities have begun measuring smog ...

Does the Brain Filter out a Wider Awareness?
The human brain has amazing capacities. It contains billions of neurons, allowing it to process vast quantities of information so that we can function effectively. But can we have too much information? Yes, and, in fact, filtering information is one of the brain's most important functions. Brain filtering is an adaptive strategy and ensures that only the information relevant to our goals is allowed into our consciousness. This keeps us from being flooded with irrelevancies that might distract us.
To introduce brain filtering to my neuroscience students, I show them a video of two teams throwing a ball back and forth, and ...

Moms Lose Up To 9 Hours Of Sleep Every Week
Here's another reason to take a minute to appreciate everything your mom's sacrificed for you this Mother's Day: Her sleep.
Not that anyone who’s paced the hallway trying to sooth a crying infant needs proof, but several studies have documented that new parents and parents of young children miss out on a whole lot of sleep.
Now, a new population-level research in Australian quantified just how much sleep working Aussie parents are missing out on, compared to their colleagues without children. The results of the survey indicated that fathers of young kids are missing out on one to four hours of sleep each w...

Why We Study Sleep
This post is adapted from a speech delivered at a Fireside Chat between Arianna Huffington and Andre Iguodala on April 11, 2016 at Stanford University. You can watch the event here. Before introducing our famous guests, as director of the Center for Sleep Sciences and Medicine, I have been asked to introduce the topic of sleep and sleep disorders and why we should bother to study sleep. This is not difficult for me as sleep is my passion. The first reason for studying sleep is simply that sleep is one of the last remaining mysteries in biology. We still don't understand why a typical human has to spend 25 years of life sle...

Experts Say Vegetable Oil May Not Be As Healthful As We Thought
The American Heart Association, U.S. Dietary Guidelines and most doctors and nutritionists say that if you eat more "healthy fats" from vegetable and seed oils and less "bad fats" from red meat and dairy products, you're on your way to better cardiovascular health. It turns out that may not be supported by the highest standards of scientific evidence. A new analysis of never-before-published trial data from the 1960s and '70s pokes holes at the notion that we can stave off heart attack and stroke by eating more polyunsaturated fat (the "healthy" kind). Instead, it suggests that some people who eat more of this f...

White Doctors In Training Believe Some Disturbing Stuff About Black Patients
When it comes to emergency care, you may have a tough time if you're in pain and not a white man. Previous research has shown that black and Hispanic patients who reported severe pain in the the ER were 22 percent less likely to receive pain medication than white patients who presented with the same complaints. And women suffer similar disparities: A 2008 study found that women wait an average of 16 minutes longer to receive pain relief for acute abdominal pain in the ER than men do. Now a new study is shedding some light on this phenomenon. "We’ve been looking at racial bias and pain perception to tr...

What Is Life?
Zombies and the walking dead make for good copy, but do little to advance our understanding of life and death. Unfortunately, neither did the National Geographic with a cover article entitled, "The Science of Death: Coming Back from the Beyond." The article issues forth just about every misconception of life that permeates our national discussion. Sam Parnia, a critical care physician and author of the book Erasing Death, is quoted as saying that death "is a process, not a moment." So far so good. But then he makes a common but critical error in thinking, which gets to the heart of our problem. In discussing a victim of a ...

The Number Of Adults With Diabetes Has Quadrupled To 422 Million
By Kate Kelland LONDON (Reuters) - The number of adults with diabetes has quadrupled worldwide in under four decades to 422 million, and the condition is fast becoming a major problem in poorer countries, a World Health Organization study showed on Wednesday. In one of the largest studies to date of diabetes trends, the researchers said ageing populations and rising levels of obesity across the world mean diabetes is becoming "a defining issue for global public health". Type 2 diabetes is a long-term condition characterized by insulin resistance. Patients can manage their diabetes with medication and diet, but the disease ...

Patty Duke's Death Announcement Is A Milestone For Sepsis Awareness
Oscar-winning actress Patty Duke, star of "The Patty Duke Show" and the Broadway play and film “The Miracle Worker,” died of sepsis from a ruptured intestine on Tuesday. Simple though it may seem, her death announcement is a major milestone for the sepsis awareness movement, said Thomas Heymann, executive director of the Sepsis Alliance. The more people are aware of this condition, Heymann said, the stronger their likelihood of saving their own lives or the lives of their loved ones. "The fact that they said Patty Duke’s cause of death was sepsis is relatively new," Heymann said. "It very often ...

Pinkies Up! There Could Be Some Real Health Benefits To Drinking Tea
Tea gets short shrift as coffee’s milder little sister. But these leaves may have a lot more to offer drinkers than just their subtle taste. Large, observational studies have found lifelong tea drinkers are less likely to face early cognitive decline and get certain types of cancer, stroke, coronary heart disease, and type 2 diabetes. We should also note that by “tea,” we mean the leaves from the Camellia sinensis plant that are plucked and processed in different ways to make black, green, white, oolong and pu’er teas -- not herbal infusions like peppermint, hibiscus and chamomile teas. Researchers ...

Men With Psoriasis Could Be More Likely To Have This Sexual Problem
(Reuters Health) - Men with psoriasis may be more prone to erectile dysfunction than their peers without this skin disease, and their odds of sexual difficulties are even higher if they are depressed or have other health problems like diabetes or high blood pressure, a Chinese study suggests. Researchers studied sexual function in 191 patients with psoriasis and an equal number of healthy men. They found 53 percent of the men with psoriasis reported erectile dysfunction, compared with 40 percent in the healthy control group. Men with psoriasis were significantly more likely to report severe erectile dysfunction, whil...

Pretty Much Nobody In The U.S. Leads A Healthy Lifestyle
Only 2.7 percent of U.S. adults hit the four key metrics of living a healthy lifestyle -- abstaining from smoking, eating well, exercising and maintaining a healthy body fat percentage -- according to a disheartening new study. The study's lifestyle benchmarks for health weren't particularly high. Being smoke-free, exercising moderately and eating USDA recommended foods don't seem like particularly difficult marks to hit. So why do so many Americans fall short of living healthy lives? "That is the million dollar question," Ellen Smit, a senior author of the study and an associate professor at the Oregon State Un...
