A Centuries-Old Aphrodisiac Might Help People With Sleep Apnea
This study is the first time that researchers are aware of that the chemical has been used to help to treat sleep apnea, Poon said. The recent experiments were done in rats ― so a drug available for people is still a long way off. (The chemical still needs to be formulated into a drug and then be tested on humans.) But the scientists are excited because if the chemical does have the same effect in people, it may be pivotal in designing the first drug to target the root cause of obstructive sleep apnea. ‘Waking Up’ The Tongue Muscles In people with sleep apnea specific motor neurons (the nerve cells that cont...

Complementary roles of gasotransmitters CO and H2S in sleep apnea Physiology
Sleep apnea, which is the periodic cessation of breathing during sleep, is a major health problem affecting over 10 million people in the United States and is associated with several sequelae, including hypertension and stroke. Clinical studies suggest that abnormal carotid body (CB) activity may be a driver of sleep...

Want Your Teen To Have A Healthy Weight? Science Says Shut Up
Experts agree that talking about the need to diet and lose weight is one of the most unhealthy, counterproductive things a parent can do for a teen who is struggling with weight issues. Now, new guidelines from the American Academy of Pediatrics formally endorse those findings. In order to prevent obesity and eating disorders, parents should focus less on diets and the scale and emphasize family togetherness and exercise for fitness, not weight loss. The AAP included both obesity and eating disorders in their recommendations because these often share unhealthy behaviors such as dieting, bingeing and having a diss...

Insomnia? Oversleeping? Both may increase your risk of stroke
There is growing evidence that sleep disorders like insomnia and sleep apnea are related to stroke risk and recovery from stroke, according to a recent literature review.

Sleep disorders may predict heart events after angioplasty
People who have had procedures to open blocked heart arteries after acute coronary syndrome (ACS) may have a higher risk of death, heart failure, heart attack and stroke if they have sleep disorders, such as sleep apnea, compared to those who don't. The presence of sleep disorders in ACS patients is an important predictor of major cardiovascular events after angioplasty.

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...

What Your Tongue And Tonsils Could Tell You About Your Sleeping Habits
Your dentist might be able to tell if you're having trouble sleeping.  Yes. A new study published in the Saudi Medical Journal found that the size of a person's tonsils may indicate their risk for obstructive sleep apnea, a condition in which blocked upper airways cause breathing to stop and restart repeatedly during sleep. Tongue indentations, or teeth imprints on the tongue that suggest it's too big for the mouth, may also be a sign.  More than 18 million adults in the United States are affected by OSA. Since people with the condition are often suffering from interrupted and reduced sleep, it can lead to ...

Catching Dick: Not Why We Care About Weight
Amy Schumer said in her humorous acceptance speech at the Glamour Women of the Year Awards: "I'm like 160 pounds right now, and I can catch a dick whenever I want, and that's the truth." The line, like many in her speech, is obviously very funny. But the humor is directed at a misperception that is not so funny. With our society's superficial focus on youth and appearance, we have emphasized all the wrong reasons for maintaining a healthy body weight, which has nothing to do with "catching dick." We are sold the idea that remaining slim is primarily important as a means of attracting the opposite sex, rather than as a pa...

Rising prevalence of sleep apnea in US threatens public health
Public health and safety are threatened by the increasing prevalence of obstructive sleep apnea, which now afflicts at least 25 million adults in the US, according to experts. Several new studies highlight the destructive nature of obstructive sleep apnea, a chronic disease that increases the risk of high blood pressure, heart disease, Type 2 diabetes, stroke and depression.

Severity of sleep apnea impacts risk of resistant high blood pressure
A strong association between severe, untreated obstructive sleep apnea and the risk of elevated blood pressure despite the use of high blood pressure medications has been made by researchers. "High blood pressure that is resistant to treatment with medications is a strong warning sign for the presence of obstructive sleep apnea, a chronic disease that increases the risk for heart disease and stroke," said one expert.

Severe sleep apnea linked to increased risk of stroke, cancer, death
Moderate to severe obstructive sleep apnea is independently associated with an increased risk of stroke, cancer and death. Results of the 20-year follow-up study show that people with moderate to severe obstructive sleep apnea were four times more likely to die (hazard ratio = 4.2), nearly four times more likely to have a stroke (HR = 3.7), three times more likely to die from cancer (HR = 3.4), and 2.5 times more likely to develop cancer. Results were adjusted for potential confounding factors such as body mass index, smoking status, total cholesterol and blood pressure.

Sleep apnea common among stroke-related brainstem injuries
People whose brainstems are affected by their stroke have a significantly higher prevalence of sleep apnea than those who have stroke-related injury elsewhere in the brain, according to new research. Sleep apnea is marked by interrupted breathing during sleep and can lead to serious health problems including heart disease and stroke.
