ClassX Video Lessons Youtube Channel MinuteEarth How The Modern World Tricks Our Bodies Into Hurting Themselves
Hi there! Today, we’re diving into how our bodies sometimes get confused by the modern world, leading to unexpected health issues. Let’s explore how this happens and what we can do about it.
Throughout history, humans have faced threats like injuries and infections. To protect us, our bodies developed systems to respond when our defenses are breached. One key player in this process is an enzyme called COX, found in tissues all over our bodies.
When we get hurt, COX produces a chemical that makes platelets extra sticky. These platelets rush to the injury site to form clots and stop bleeding. Similarly, during an infection, COX helps widen blood vessels, allowing immune cells to flood in and fight off invaders.
Today, the threats we face have changed. Pathogens and physical injuries aren’t as common, thanks to advances in medicine and safety. However, our COX enzymes haven’t adapted to this new reality. Ironically, COX’s responses can sometimes cause more harm than good in our modern lives.
For instance, our sedentary lifestyles and fatty diets can lead to cholesterol buildup in our blood vessels. If a cholesterol deposit ruptures, COX might mistakenly trigger the sticky platelet response, leading to clots that block blood flow. This can result in heart attacks or strokes.
Moreover, our behaviors can trick our bodies into thinking there’s an infection when there isn’t. COX responds by sending immune cells and fluids, which can contribute to autoimmune diseases, depression, and even some cancers. As a result, while our risk of dying from injuries and infections has decreased, COX-related issues have become more prevalent.
We don’t want to eliminate COX entirely, as it’s crucial for dealing with real injuries and infections and protecting our stomach lining. However, for certain groups, like older adults with more cholesterol deposits, it might be beneficial to reduce COX’s reaction to perceived threats.
Aspirin, a common pain reliever, can inhibit COX, lowering the risk of some COX-related problems. While regular Aspirin use carries risks like internal bleeding and stomach ulcers, studies suggest that people over 50 with high heart risk who take low-dose Aspirin tend to have lower healthcare costs and longer lifespans.
In today’s world, one of the best ways to protect our health is by managing how our bodies respond to perceived threats. Understanding and controlling COX’s actions can help us live healthier, longer lives.

Hi, this is David from MinuteEarth. Throughout history, the biggest threat to humans has been physical harm, either through injury or infection. It’s not surprising that our bodies have developed internal systems that respond once our external defenses have been breached. One of those systems is led by a special enzyme called COX, which is found in tissues throughout our bodies.
When we get injured, nearby COX produces a chemical that triggers the production of extra sticky platelets, which rush to stop the bleeding by clotting the wounds. When we have an infection, COX makes a different chemical that helps dilate our blood vessels, allowing a rush of fluid to bring immune cells to fight the intruders.
However, the world has changed; pathogens and violence are no longer our biggest threats, and we have other, sometimes better, ways to deal with them. Our COX enzymes don’t recognize this change. Ironically, we may be more likely to be harmed by COX’s response to perceived threats than from actual injuries and infections.
In the modern world, COX is often triggered unnecessarily, leading to potentially disastrous results. For example, modern humans, with sedentary lifestyles and fatty diets, are more likely to build up cholesterol deposits in our blood vessels. If one of these deposits breaks open, COX can mistakenly initiate the same sticky platelet response as it does with a ruptured blood vessel. This can lead to clots that stop blood flow, resulting in heart attacks or strokes.
Additionally, our modern behaviors can cause our bodies to mistakenly think there are infections present when there are not. COX responds by flooding our system with fluid and immune cells, which can lead to autoimmune diseases, depression, and certain types of cancers. Consequently, even as our chances of dying from injuries and infections have decreased, our chances of dying from COX-related issues have increased.
We don’t want to eliminate COX entirely, as it is still important for serious injuries and infections and helps protect our stomach lining. However, for certain populations, such as older individuals with more cholesterol deposits, it may be beneficial to lower COX’s ability to react to perceived threats.
Aspirin, a common pain reliever, can inhibit COX, thereby reducing the risk of certain COX-related problems. While taking Aspirin regularly has some risks, such as increased chances of internal bleeding and stomach ulcers, studies show that individuals over 50 with a high risk of heart problems who take low-dose Aspirin regularly tend to have reduced healthcare costs and longer lifespans.
For modern humans, it seems that one of the best ways to save lives is to deliberately manage our bodies’ responses to perceived threats.

This version maintains the original content while removing any informal language and ensuring clarity.
Cox – Cox refers to cyclooxygenase, an enzyme that is responsible for the formation of important biological mediators called prostanoids, including prostaglandins, which are involved in inflammation and pain. – Inhibiting the cox enzyme can help reduce inflammation and alleviate pain in patients with arthritis.
Enzymes – Enzymes are biological molecules that act as catalysts to accelerate chemical reactions within the body, playing crucial roles in processes such as digestion and metabolism. – Digestive enzymes break down food into nutrients that the body can absorb and utilize for energy and growth.
Health – Health refers to the overall condition of an organism at a given time, encompassing physical, mental, and social well-being, not merely the absence of disease or infirmity. – Maintaining a balanced diet and regular exercise are essential components of good health.
Cholesterol – Cholesterol is a waxy, fat-like substance found in all cells of the body, necessary for the production of hormones, vitamin D, and substances that help digest foods. – High levels of cholesterol in the blood can increase the risk of heart disease.
Immune – The immune system is the body’s defense mechanism against infections and diseases, consisting of a network of cells, tissues, and organs that work together to protect the body. – A strong immune system can effectively fight off pathogens and prevent illness.
Infections – Infections occur when harmful microorganisms such as bacteria, viruses, fungi, or parasites invade the body, multiply, and cause disease. – Proper hygiene and vaccinations are important measures to prevent infections.
Autoimmune – Autoimmune refers to a condition in which the immune system mistakenly attacks the body’s own healthy cells and tissues, leading to various diseases. – Rheumatoid arthritis is an autoimmune disorder where the immune system targets the joints.
Lifestyles – Lifestyles refer to the habits, attitudes, tastes, moral standards, and economic level that together constitute the mode of living of an individual or group, significantly impacting health and well-being. – Adopting healthy lifestyles, such as regular physical activity and a balanced diet, can reduce the risk of chronic diseases.
Aspirin – Aspirin is a medication used to reduce pain, fever, or inflammation, and it works by inhibiting the production of certain natural substances that cause inflammation in the body. – Doctors often recommend low-dose aspirin to help prevent heart attacks in high-risk patients.
Diseases – Diseases are disorders or malfunctions of the body or mind that lead to a departure from good health, often characterized by specific signs and symptoms. – Infectious diseases can spread rapidly in populations without proper public health measures.
