This trial suggests that humidifiers is also effective in reducing altitude-related nasal symptoms for long period. Humidifiers add moisture to the air, which helps ease breathing. Warm-mist and CMH’s are equally effective in humidifying the air. What relieves the symptoms of altitude sickness? Treating altitude sickness stop and rest where […]
When you say altitude sickness, most people – including me – think of headache, shortness of breath, maybe some nausea or vomiting. I learned, though, that high altitude can also aggravate diarrhea or constipation, and cause “intestinal gas” – i.e., bloating and increased farts. Why do I get bloated in […]
According to NASA, civilian astronauts are awarded a pay grade of anywhere from GS-11 to GS-14, so the income range is relatively wide. Starting salaries begin at just over $66,000 a year. Seasoned astronauts, on the other hand, can earn upward of $144,566 a year. How much do astronauts get […]
If it was slower then one full rotation would take more than 24 hrs., thus making days & nights longer. Our weight would be more, because as the Earth would rotate slower, it would exert less centrifugal force on us. Do we age faster if the Earth spins faster? The […]
In other words, yes, time dilation does affect biological aging. Do you age faster in space? In 2020, scientists at the University of Rome Tor Vergata found that exposure to cosmic radiation damages cells and causes the onset of diseases normally associated with aging. The authors of the new study […]
Yes, time really does run faster at the top of a mountain than down at the bottom, due to gravitational time dilation. The difference can be expressed as a dimensionless ratio, as others have said. The ratio is proportional to the gravitational potential difference, which itself is proportional to the […]
Some extra red blood cells can be a good thing in high altitude, low oxygen environments — they help keep blood oxygenated — but too many thicken blood, increasing a person’s risk of heart attack and stroke, even in young adults. What does high altitude do to your blood? Altitude […]
Early research suggests that simply relocating to a higher altitude for a while can help overweight people shed some pounds. That is exactly what happened when researchers in Germany took 20 middle-aged, obese men to the mountains for a week in a study designed to help explain altitude-related weight loss. […]
The cause of this rash is unclear but is thought to be related to changes at high altitudes affecting vasomotor nerve function, decreased capillary elasticity with persistent expansion, and increased blood viscosity secondary to increased hemoglobin. Why do people in high altitude have red cheeks? Red cell concentration becomes considerably […]
26,000 feet. So how high can we climb before we need oxygen? 26,000 feet (8,000 meters) is the official ‘Death Zone’ where severe altitude sickness occurs without the use of supplemental oxygen. Do you need oxygen at 14000 feet? At its extreme, this desaturation of oxygen is what leads people […]
The altitude training improves your metabolic rate. After a workout at a higher altitude you will be able to burn more calories over the next 12 – 15 hours, which means you are still burning calories while sitting in front of the television. You will also be able to gain […]
When you say altitude sickness, most people – including me – think of headache, shortness of breath, maybe some nausea or vomiting. I learned, though, that high altitude can also aggravate diarrhea or constipation, and cause “intestinal gas” – i.e., bloating and increased farts. Does altitude change affect bowel movements? […]
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s […]
If you look at the Earth’s geoid, you can see that there isn’t a particular “band” of gravitational variation along the equator. So while time would move slower / faster at varying locations around the globe, it is not correlated with the equator. Is time slower at the equator? Clocks […]
It’s 6,035-foot elevation is a “sweet spot” that provides the most conditioning benefit in terms of ideal oxygen deprivation. The relationship between lower body weights and altitude comes with several hypothesis. Is living at higher altitude healthier? The available data indicate that residency at higher altitudes are associated with lower […]
