☆ Drinking alcohol before napping on flights presents health risk, study finds
▼ + stars: | 2024-06-05 | by ( Jenni Reid | ) www.cnbc.com time to read: +1 min

A popular pastime on long-haul flights — drinking alcohol before dozing off to sleep — may present health risks even to young and healthy passengers, according to a new study. The combination of alcohol consumption, sleep and the low oxygen concentration at high altitudes was found to challenge the cardiovascular system and extend the duration of hypoxaemia, or low levels of oxygen in the blood. Inflight sleep already exacerbates the fall in blood oxygen saturation caused by the reduced atmospheric pressure in aircraft cabins, the study states. Under the added effect of alcohol consumption, lab tests showed that participants' blood oxygen saturation decreased further, their heart rate increased and deep sleep was reduced. Even "young and healthy participants" suffered from "clinically relevant" desaturations and heart rate accelerations during sleep, the study found.

CNN —The “fasten seat belt” sign is off, and the time for a nap on your flight is on. On the nights with alcohol, researchers saw a lowered amount of oxygen and an increased heart rate, the study showed. Alcohol gets you sleep — but not good sleepThe study authors didn’t just collect data on heart strain. Alcohol may help you get to sleep, but the quality isn’t as good as sleep while sober, he said. “Many people have witnessed when people drink heavily, their snoring and the sleep apnea is much more severe,” Freeman said.

☆ What it would take for humans to actually survive the harsh conditions on Dune's planet Arrakis

Frank Herbert first described this harsh, fictional world of Arrakis in his 1965 novel "Dune," which was recently adapted into a film trilogy. The movie was shot in the deserts outside Abu Dhabi, but we wondered what it would actually take to survive on a real-life Arrakis. AdvertisementDune's planet Arrakis has enormous sandworms, a drug known as spice that helps with interstellar travel, and two moons. Planet Arrakis lacks oceans, lakes, or even tiny puddles on its surface. Surviving the temperature extremesIf the lack of water on Arrakis doesn't kill you, the heat certainly will if you're not prepared.

☆ What happens when an airplane cabin suddenly depressurizes?

CNN —A loud bang, a jolt, and cold air whooshing suddenly through the cabin: these were the immediate signs that something was very wrong aboard Alaska Airlines flight 1282, according to one passenger report. As investigators work to determine exactly what caused the incident, we look at what happens when an aircraft experiences a sudden loss of cabin pressure and the risks for those on board. “As the aircraft climbs, the cabin pressure will eventually settle to about 8,000 feet. The flight crew will immediately start working to get the aircraft down to about 10,000 feet, where the air will be breathable. There will also be a massive wind blast as all that pressure in the cabin goes out the hole.

WASHINGTON (AP) — The Air Force is expanding its study of whether service members who worked with nuclear missiles have had unusually high rates of cancer after a preliminary review determined that a deeper examination is needed. In response, medical teams went out to each nuclear missile base to conduct thousands of tests of the air, water, soil and surface areas inside and around each of its three nuclear missile bases; Malmstrom Air Force Base in Montana, Minot Air Force Base in North Dakota and F.E. Warren Air Force Base in Wyoming. For years the missileers were told in multiple Air Force reviews that there was not cause for concern. While the Air Force review is looking at a broader set of cancers, the number of self-reported NHL cases is striking because the community of missile launch officers is very small.

☆ The Bodily Indignities of the Space Life

But the space-based medical science needed to make that possible has been hindered by small sample sizes that aren’t representative of the general population. As less-rigorous medical screening allows more tourists to reach space, the chances increase significantly that someone will get hurt or have a health emergency there. And if we survived those perils, wouldn’t escalating pressure in our skulls kill us after a week or so? Initially, many space travelers puke, or at least feel motion-sick — space-adaptation syndrome, or S.A.S., is what such nausea, headache and vomiting are called outside our atmosphere. symptoms in the 1970s, when they heard Skylab astronauts talking about it with one another over a hot mic.

☆ Federal authorities have been probing roughly 5,000 pilots suspected of withholding major health issues that could imperil their ability to fly safely, report says

Federal officials are probing roughly 5,000 pilots suspected of withholding major health issues, per The Washington Post. Many of the other pilots possess commercial licenses, which gives them ability to be hired to fly for a range of clients. Pilots have to pass regular health screenings, but according to The Post, the tests are often not always comprehensive. "The vast majority of these pilots may continue to operate safely while we complete the reconciliation process." "I know of a lot of pilots who have told me about [medical conditions] they aren't telling the FAA about," he said.
