24 Hours Inside Your Body

It’s the world’s first human body rig – two ordinary people are filmed going about their typical day while covered from head to toe in medical, monitoring equipment. What will they discover about how their lifestyle affects their health and what will the rest of us learn about how the human body works?

The volunteers for this unique medical experiment are under scrutiny for 24 hours as they navigate the obstacle course of everyday life. Everything they do, from how they sleep, to what they eat, to their emotional responses to their environment impacts their overall health. Charlotte, 31, is a hairdresser and mom and Dave, a 43-year-old, runs his own courier business from the family home. Wearing the latest, non-invasive medical technology, their heart rate, glucose levels, respiration, blood pressure, posture, movement and brain waves are monitored, second by second. Charlotte and Dave think they’re reasonably healthy, but are they? Charlotte admits to regular headaches and Dave’s recent weight loss seems to have stalled and he’s often tired.

Watching their every move are three leading scientists. Professor Tom Solomon, a world-renowned neurologist, looks at how their brains respond throughout the day; Dr. Jason Gill, a physiologist, monitors how their bodies react to both their physical activity and to everything they eat; and Dr. Lia Ali, a psychiatrist, studies how their emotional experiences are tied to their physical well being. The scientists watch the video footage and then marry it with the data collected by the body rig to gain a unique insight into how every detail of a typical day affects the health of the human body.

At the end of the experiment, the experts meet Dave and Charlotte for the first time to present the results. How will the volunteers react once the medical detectives reveal what’s going on inside their bodies? With access to this incredible data, will they be willing to change their lifestyle to improve their future health?

Video: Making the Perfect Dry-Aged Burger

Three chefs play with all parts of the dream burger — except the bun, which is potato of course. There’s a healthy sauce debate between a spicy version of special sauce that’s turned up with a lot of dijon mustard, against a ketchup and fish sauce concoction and a soubise — a classic French sauce made mostly of onions.

Drones a Lifesaver for Cardiac Arrest Patients

Drones, the unmanned aircraft that got its start as part of the U.S. military’s arsenal and is today being used by everyone from photographers to farmers, are now heralded as a solution to a problem that’s bedeviled emergency medical personnel for years: How to deliver lifesaving defibrillators to people suffering cardiac arrest in areas not quickly reached by ambulances.

Experiencing a cardiac arrest — when the heart stops due to an electrical malfunction in the heart — is almost always a death sentence when suffered outside a hospital. Of the more than 356,000 out-of-hospital cardiac arrests each year in the United States, nearly 90 percent of them are fatal, according to statistics from the American Heart Association.

The survival rate could be dramatically improved, experts said, if bystanders would perform CPR and use portable devices called automated external defibrillators, or AEDs. Research shows brain cell death starts three minutes after the heart stops beating and every minute that elapses without defibrillation means a 10 percent decrease in the odds of survival.

Drones are being tested to see if they can swiftly and safely bring defibrillators to those in distress. Some drones use a cord to lower the AED to the ground, while others land and a bystander removes the AED.

A Canadian study published in Circulation last year found that when compared to ambulances, using drones in the Toronto area cut AED delivery times in urban areas by 6 minutes, 43 seconds and slashed it in rural neighborhoods by 10 minutes, 34 seconds in most cases. Likewise, a Swedish study published in JAMA last year showed that drones deployed in Stockholm took an average of 5 minutes, 21 seconds to reach their destination — more than 16 minutes faster than ambulances.

“Faster response time should lead to higher survival,” said Timothy Chan, director of the Centre for Healthcare Engineering at the University of Toronto and an author of the Toronto study. “Getting a defibrillator is time-sensitive and literally every second counts. If we can do it and keep people safe, this is a no-brainer.”

It’s unclear if drones have ever successfully delivered AEDs in real-life situations. The Toronto study applied mathematical models to out-of-hospital cardiac arrests that occurred in the city from 2006 to 2014. The Swedish study dispatched drones and ambulances to the same location as an experiment though no patients were involved.

However, the opportunity for real-life experience is growing.

The city of Reno, Nevada, was selected last month to participate in the Federal Aviation Administration’s drone pilot program that will help determine how to regulate and safely integrate drones into the U.S. airspace. The city will partner with drone delivery startup Flirtey to deliver AEDs.

The Canadian County of Renfrew began using drones last year and has deployed one roughly every two weeks to provide services such as conducting reconnaissance and delivering medicine, said Michael Nolan, chief paramedic and director of emergency services for the county of 100,000 people located just outside of Ottawa. They recently deployed a drone with an AED, but the ambulance arrived first.

However, the county is awaiting approval from Canadian regulators to fly drones a distance of 4 nautical miles (4.6 miles), an increase from the currently approved 2 nautical miles (2.3 miles), increasing the chances the aircraft could be used to deliver a defibrillator.

Nolan said he worked with Canadian regulators for two and a half years to pave the way for the first approval — a time span he called “a blink of an eye in the public policy world,” especially given that drones are still a relatively new technology.

“The biggest concern that we and the regulators shared was making sure we were integrated with the aviation community to make sure that people in the air and on the ground were safe,” said Nolan.

Together they set limits on how high and far the drones could fly. Test runs proved to regulators the drones could fly safely even though the operators couldn’t see the aircraft. The drones also needed some modifications such as being formatted to fly at night. Meanwhile, 911 operators had to learn how to instruct bystanders to approach the drone and use the defibrillator.

“It is a lifesaving device that provides a benefit,” said Nolan. “When you do the safety-risk assessment, it is clear that the risk associated with doing something outweighed the risk of doing nothing.”

We All Need Water for a Healthy Life, But How Much?

During the summer — and even year-round — our bodies crave water. There’s no way to live without it. But just how much do we really need every day to stay healthy?

The answer can get complicated.

“It’s hard to find an exact amount because it’s variable based on your age, where you live, whether it’s hot and humid, or cold and dry. Are you male or female, more active or less active,” said Ilyse Schapiro, a registered dietitian with nutrition counseling practices in New York and Connecticut.

Studies have shown that water keeps the mind and body healthy, transporting nutrients, removing waste, regulating body temperature and keeping the cells working.

Although the total amount varies by age, gender and body composition, our bodies are 55 percent to 78 percent water.

The Food and Nutrition Board at the federal Institute of Medicine offers an estimate on a healthy balance of water for adult men and women. It suggests men have about 3.7 liters daily. That’s about 15, 8-ounce glasses. Women should have about 2.7 liters, or 11 glasses.

But drinking water isn’t the only way to stay hydrated. Most people get about 20 percent of their water from food.

Dr. Michael Sayre, an emergency medicine doctor at Harborview Medical Center in Seattle, said most people can — and should — listen to their body and brain.

“Your brain regulates that really well,” said Sayre, who teaches emergency medicine at the University of Washington. “In terms of preventing [conditions] like heat stroke, it’s generally people who ignored the signals they were thirsty or couldn’t respond to them because they were physically impaired, or they were in an environment where they didn’t have access to water.”

Dehydration can begin within just a few hours of heavy exercise or extreme heat. Often, it happens with little notice, and by the time a person responds to their thirst they already are behind on a healthy water balance. Fatigue, headaches, dizziness, sleepiness and dry mouth can all be signs of dehydration.

“Don’t let yourself get to that point of dehydration,” Schapiro said. An obvious way to tell is the color of urine.

“We don’t want to always talk about that, but it’s a good indicator,” she said. The clearer the color, the more hydrated a person is.

In many cases, medication and certain conditions such as diabetes or heart disease can impact how much water a person needs.

“A lot of high blood pressure and other types of medications tend to be diuretics,” which cause the body to lose more water, Schapiro said. “In those cases, people should work with their doctor to make sure they are paying attention to hydration and keeping a healthy balance.”

Sometimes, Schapiro said, people miss cues and mistake thirst for hunger. So, she counsels clients to keep a bottle of water at their side to drink from all day long.

“People forget to include water in nutrition,” she said. “People are busy and just not thinking about it. … If you are not well-hydrated during the day, you could be more likely to get a snack when you don’t need it.”
