Have you ever wondered why you might feel a bit strange when flying on an airplane? Today, we’re going to explore how altitude impacts our bodies and why these changes occur.
Most of us live at or near sea level, where the air pressure is stable, and our bodies have adapted to these conditions. At sea level, our lungs can easily fill with oxygen, which is crucial for our health and well-being.
However, as we ascend to higher altitudes, such as when climbing a mountain or flying in an airplane, the air pressure decreases. This means there’s less oxygen available, which can lead to various symptoms as our bodies adjust to the change.
When you fly in a commercial jet, the plane typically cruises at around 30,000 feet. However, the cabin is pressurized to mimic an altitude of about 8,000 feet to make it more comfortable for passengers. Even at this altitude, the reduced air pressure means there’s less oxygen, which can cause some noticeable effects on your body.
At 8,000 feet, the lower oxygen levels can lead to a condition called hypoxia, where not enough oxygen reaches your brain. Your body might respond by increasing your breathing and heart rate to compensate, which can cause discomfort. This increased blood flow to the brain can result in headaches, while reduced blood flow to the digestive system may cause nausea and loss of appetite.
If the cabin weren’t pressurized, and you were exposed to the conditions at cruising altitude, the effects would be much more severe. Altitude sickness becomes a risk above 8,000 feet, and at 18,000 feet, the oxygen levels are significantly lower than at sea level. Areas above 25,000 feet are known as the “Death Zone” because the air contains only one-third of the oxygen found at sea level, making breathing extremely difficult.
At very high altitudes, the stress on your body can lead to serious conditions like HAPE (High Altitude Pulmonary Edema), where fluid accumulates in the lungs, and HACE (High Altitude Cerebral Edema), which affects the brain. Both conditions require immediate medical attention and can be life-threatening if not treated with supplemental oxygen.
So, how do people manage to ski in Colorado or climb Mount Everest? The answer is acclimatization! It typically takes a few days for the body to adjust to higher altitudes. During this time, your body becomes more efficient at taking in oxygen and increases red blood cell production to help transport oxygen more effectively.
Next time you’re on a long flight, consider watching some interesting shows to pass the time. You can explore great content on the DiscoveryGo app, including the series “When We Left Earth.” Check it out in your app store for some fascinating viewing options.
Now that you understand why you might feel lightheaded on airplanes, you might be curious about how we manage to breathe in such environments. Would you ever consider climbing Everest? Let us know your thoughts, and don’t forget to explore more educational content to keep learning every day!
Conduct a simple experiment to simulate the effects of altitude on air pressure. Use a plastic bottle and a balloon to demonstrate how air pressure changes with altitude. Inflate the balloon inside the bottle and observe how it behaves when you squeeze the bottle. Discuss how this relates to the changes in air pressure and oxygen availability at different altitudes.
Research a famous high-altitude location, such as Mount Everest or the Andes Mountains. Create a presentation that explains how people acclimatize to these altitudes and the challenges they face. Include information on the symptoms of altitude sickness and how climbers prepare for such expeditions.
Engage in a role-playing activity where you simulate a flight at high altitude. Assign roles such as pilot, flight attendant, and passengers. Discuss how each role would respond to a sudden drop in cabin pressure and what measures are taken to ensure passenger safety.
Write a short story from the perspective of a climber experiencing altitude sickness. Describe the physical and mental challenges they face and how they overcome them. Use descriptive language to convey the sensations and emotions involved in acclimatizing to high altitudes.
Create an interactive quiz using online tools to test your understanding of how altitude affects the body. Include questions about air pressure, symptoms of hypoxia, and the process of acclimatization. Share the quiz with classmates and compare your results to reinforce learning.
Sure! Here’s a sanitized version of the transcript:

The best thing about flying first class? Enjoying complimentary beverages! While some myths suggest that you get intoxicated faster at high altitudes, that’s not entirely accurate. Studies indicate that your blood alcohol level remains consistent regardless of your location. If you feel a bit off after one drink on a plane, it’s more likely due to the altitude itself.
Hello everyone! I’m Amy, and today on DNews, we’re diving into how altitude affects our bodies. Most of us live at or near sea level, where humans have evolved to thrive. At this level, the atmospheric pressure is stable, allowing our lungs to fill easily with oxygen, which is essential for our health.
As we ascend, such as when climbing a mountain, the air pressure decreases. This thinning atmosphere means there’s less oxygen available, which can lead to various symptoms. Most people will experience altitude changes when flying. Commercial jets typically cruise at around 30,000 feet, but the cabin is pressurized to mimic an altitude of about 8,000 feet. While this is more challenging for your body, it’s not usually noticeable.
At 8,000 feet, the reduced air pressure means less oxygen, which can lead to symptoms of hypoxia, where insufficient oxygen reaches the brain. Your body may respond by increasing your respiration and heart rates to compensate, which can cause discomfort. Increased blood flow to the brain can lead to headaches, while reduced blood flow to the digestive system may cause nausea and loss of appetite.
If the cabin weren’t pressurized and you were exposed to the conditions at cruising altitude, the effects would be severe. Above 8,000 feet, altitude sickness becomes a risk. At 18,000 feet, the oxygen levels are significantly lower than at sea level, and areas above 25,000 feet are known as the “Death Zone.” At Everest’s peak, the air contains only one-third of the oxygen found at sea level, making breathing extremely difficult.
The stress on your body at such heights can lead to serious issues, including HAPE (High Altitude Pulmonary Edema), which involves fluid accumulation in the lungs and can be life-threatening if not treated with supplemental oxygen. HACE (High Altitude Cerebral Edema) affects the brain and requires immediate medical attention.
So how do people manage to ski in Colorado or climb Everest? The answer is acclimatization! It typically takes a few days for the body to adjust to higher altitudes, improving its efficiency in oxygen intake and increasing red blood cell production.

This version removes any informal language and references to alcohol while maintaining the informative content.
Altitude – The height of an object or point in relation to sea level or ground level. – Mountain climbers often face challenges as they ascend to higher altitudes where the air is thinner.
Oxygen – A colorless, odorless reactive gas that is essential for respiration in living organisms. – Plants produce oxygen during photosynthesis, which is crucial for animals and humans to breathe.
Pressure – The force exerted per unit area on the surface of an object. – As you dive deeper into the ocean, the water pressure increases significantly.
Acclimatization – The process of adjusting to a new environment or different conditions, often related to altitude or climate. – Hikers need time for acclimatization when climbing high mountains to avoid altitude sickness.
Hypoxia – A condition in which there is a deficiency of oxygen reaching the tissues of the body. – Pilots flying at high altitudes without proper equipment may experience hypoxia due to low oxygen levels.
Symptoms – Signs or indications of a condition or disease. – Common symptoms of altitude sickness include headaches and dizziness.
Breathing – The process of taking air into and expelling it from the lungs. – Breathing becomes more difficult at high altitudes because the air contains less oxygen.
Heart – A muscular organ that pumps blood through the circulatory system by rhythmic contraction and dilation. – The heart works harder to supply oxygen to the body when a person is at high altitudes.
Conditions – The circumstances or factors affecting the way in which people live or work, especially with regard to their safety or well-being. – Extreme weather conditions can make scientific research in polar regions very challenging.
Sickness – A state of illness or poor health. – Altitude sickness can occur when someone ascends to high elevations too quickly without proper acclimatization.
