Summer is a great time to enjoy the outdoors with your dog, but when the temperatures spike or the fireworks come out, it's time to make sure your furry best friend is having just as good a time as you are.
When a heat wave rolls in, try to only take your dog for walks in the coolest hours of the day, advised Mark Fr...
As a weekend heat wave that put more than 15 million Americans in the Northern and Central Plains on alert slowly moves east, the nation's emergency doctors have advice to keep you safe.
"Overexposure to the sun or heat can turn into an emergency faster than most people expect," said Dr. Gillian Schmitz, president of the American College of Emergency Physicians (ACEP). By Tuesday, the hea...
The record-breaking heat that's scorching much of the United States this week poses significant heart dangers, and you need to take steps to protect yourself, the American Heart Association (AHA) says.
Keeping your body well-fueled and hydrated is a must during outdoor summer sports and exercise, a nutrition expert says.
"For summer workouts, it's important to make sure that adequate carbohydrates, fluids and electrolytes are consumed," said sports dietitian Kristen Chang, assistant director of the master's program in nutrition and dietetics at Virginia Tech University.
Warm summer nights may leave you tossing and turning in bed, but that could be the least of your worries. Just a slight rise in summer nighttime temperatures increases the risk of heart-related death for men in their 60s, a new study shows.
A spike in hospitalizations for a dangerous low-salt condition is the latest in a growing list of health threats linked to climate change.
An average global temperature increase of 3.6 degrees Fahrenheit could lead to a 14% increase in hospitalizations for critically low sodium levels in the blood, a condition called hyponatremia, according to a
Wildfires and rising temperatures are exposing more and more Americans to an air pollution double-whammy of smoke and smog, a new study warns.
Researchers found that over the past 20 years, a growing number of people in western states have been simultaneously exposed to high levels of two kinds of air pollution: Fine-particle pollution generated by
If you're among the many people who use space heaters and generators during the winter, you need to guard against fire and carbon monoxide (CO) hazards, the U.S. Consumer Product Safety Commission (CPSC) says.
In the United States, that's especially true for Black Amer...
Global warming may pose a threat to your kidneys, new research suggests.
For the study, researchers analyzed data from hospitals in more than 1,800 cities in Brazil between 2000 and 2015, and found that just over 7% of all admissions for kidney disease could be attributed to hotter temperatures.
That equates to more than 202,000 cases of kidney disease, according to the report publi...
Climate change is already making Americans sick and researchers warn that the nation must take swift action to protect people's well-being.
"Climate change effects aren't just an abstraction, something that will happen years from now. They are happening today, and they impact every aspect of your health, from the air you breathe [more smoke, more pollen] to the nutritional quality of the ...
Urban dwellers around the globe are sweating through three times as many "extreme heat" days as their counterparts did in the 1980s, a new study suggests.
The study is the latest to chart humans' growing exposure to dangerously high temperatures. Experts said it looked at what's happening in finer detail than previous research has -- and it suggests that exposure to extreme heat is more w...
Climate change is the "single biggest health threat facing humanity," and governments must "act with urgency" to tackle the crisis, a World Health Organization (WHO) special report warns.
In advance of a United Nation's climate change summit in early November, groups representing 45 million nurses, doctors and health professionals worldwide signed an open letter urging action on the clima...
It's not just athletes on the field who suffer when outdoor temperatures get too high. Members of college and high school marching bands are at increased risk of heat-related illness, too, researchers warn.
"They go out there, and they often wear these really heavy wool uniforms," said lead author Andrew Grundstein of the University of Georgia. "They practice many times for hours and hour...
Hotter weather driven by climate change is bad news for people with chronic obstructive pulmonary disease (COPD), a new study warns.
Researchers say warming trends could worsen COPD symptoms, such as shortness of breath, wheezing or coughing. Millions of people have COPD, a combination of emphysema and chronic bronchitis that is often tied to smoking.
Midsummer heat and high humidity aren't just uncomfortable -- they're a combo that can cause serious illness and even death.
"Whenever you walk or do outdoor activity, take a friend with you who can help you if you run into trouble," Dr. Eleanor Dunham advised. She's an emergency medicine doctor at Penn State Health Milton S. Hershey Medical Center in Hershey, Pa.
Extreme heat strikes poor and minority neighborhoods in U.S. cities harder than those that are wealthier and mainly white, a new study finds.
"The distribution of excess urban heat varies within cities, and as a result, communities do not share a city's extreme heat burden equally," said study co-author Jennifer Burney. She's chair of global climate policy and research at the University o...
Climate change has already become deadly enough to cause 5 million extra deaths worldwide each year, researchers report.
"This is the first study to get a global overview of mortality due to non-optimal temperature conditions between 2000 and 2019, the hottest period since the pre-industrial era," said study co-leader Yuming Guo, a professor at Monash University in Australia.
On sizzling hot summer days, it's important to guard against heat exhaustion and heat stroke, an expert says.
"Heat stroke occurs when the core temperature of the body reaches 104 degrees Fahrenheit and changes in our central nervous system take place, such as disorientation, confusion, behavioral or emotional changes or altered mental status," said Isabel Valdez, a physician assistant an...
Could trees be the key to a cool summer in the city?
Yes, claims new research that calculated just how much greenery can bring temperatures down.
"We've long known that the shade of trees and buildings can provide cooling," said study co-author Jean-Michel Guldmann. He is a professor emeritus of city and regional planning at Ohio State University, in Columbus.
Human-caused global warming is responsible for more than one-third of heat-related deaths worldwide, but the proportion is much higher in certain countries, a new study finds.
Researchers analyzed data gathered between 1991 and 2018 from 732 locations in 43 countries. They concluded that 37% of all heat-related deaths in recent summer periods were attributable to the warming of the planet...
As you head into the great outdoors this summer, keep safety in mind, an expert says.
Drowning is one of summer's risks. It only takes a few seconds and can happen without an obvious struggle, according to Dr. Seth Hawkins, a wilderness medicine expert and assistant professor of emergency medicine at Wake Forest Baptist Health in Winston-Salem, N.C.
Rising temperatures caused by climate change could trigger a worldwide increase in stillbirths, researchers warn.
The team at the University of Queensland in Australia analyzed 12 studies on the subject. They found that exposure to extremely high temperatures throughout pregnancy appeared to increase risk of stillbirth, particularly late in pregnancy.
The Middle East and North Africa are already among the hottest spots on the planet, but new research warns that if nothing is done to slow climate change there will be life-threatening heat waves with temperatures of 132 Fahrenheit or higher in those regions.
"Our results for a business-as-usual pathway indicate that, especially in the second half of this century, unprecedented super- an...
Limiting global warming to targets proposed in the Paris Agreement could keep tropical regions from reaching temperatures that are beyond human tolerability, a new study projects.
Researchers estimate that if countries are able to cap warming at 1.5 degrees Celsius above pre-industrial levels, the tropics will be spared temperatures that surpass the "survival limit." But life in the worl...
Some of the leading hotspots in the United States are on track to become even more sweltering in the coming decades -- thanks to a combination of greenhouse gas emissions, urban development and population growth.
In a new study, researchers estimate that over the course of this century, the biggest relative increases in extreme heat will hit cities in the Sunbelt -- including Atlanta;...
With much of the United States blanketed by a heat wave this week, the American Red Cross offers some survival tips.
Each year, extreme heat kills more than 600 people in the United States. And many others are at risk of heat-related illness, especially adults aged 65 and older and those with chronic medical conditions, the Red Cross noted in a news release.
Heat is an underestimated killer in the United States, a new study suggests.
According to researchers, death records indicate that heat kills as many as 600 hundred Americans each year, but moderate heat may actually be killing more than 5,000 annually. And the social distancing restrictions of COVID-19 might make staying cool harder this summer.
Can working or playing in the hot sun "fry" your brain?
Yes, claims a new, small study that found too much heat on the head hampered thinking in volunteers.
Most people know that high temperatures can cause heat exhaustion or heat stroke as the body's core temperature becomes dangerously high, but the beating sun can affect your brain even if your body temperature stays norm...
