Heat Goes for the Heart
As global temperatures rise due to climate change, so, too, will cardiovascular-related deaths, according to a new, albeit narrowly focused, study.
Researchers looked at more than 15,000 cardiovascular deaths in Kuwait between 2010 and 2016. (Kuwait lays claim to the hottest day in the last 76 years: 129 degrees Fahrenheit on July 21, 2016, and it consistently boasts high average temperatures.)
Days with more extreme temperatures (greater than 109 degrees F) were associated with three times the risk of a cardiovascular death than days when the temperature was less than 94.5 degrees F. Men were more likely to be affected by the extreme temperature days, as were those ages 15 to 64.
Body of Knowledge
There are three kinds of blood vessels in the human body. Arteries transport oxygenated blood away from the heart to tissues in the body. Veins carry oxygen-depleted blood from tissues back to the heart. Capillaries, which are smaller than the width of a human hair, connect arteries to veins and allow nutrients in the blood to diffuse to the body's tissues.
Get Me That, Stat!
Children think about suicide more than their parents or caregivers suspect. A new study of nearly 8,000 children throughout the U.S. found that roughly 8 in every 100 kids who are 9 or 10 years old think about suicide or act on those ideas.
Suicide is the second-leading cause of death in children 10 to 14 years old. Emergency visits and hospital stays for children who thought about or attempted suicide have doubled in the last 10 years.
The strongest risk factors are kids' psychological problems and family conflict. Another risk factor: excessive screen time.
