Hey there! I’m Craig from Mental Floss on YouTube, and today we’re diving into a big question: Why do some people feel more joint pain when it rains? If you’ve ever heard someone say their knees can predict the weather, you’re not alone. Many people with arthritis notice their joints aching more when the weather changes. Let’s explore why this might happen!
There was an interesting study published in a journal called Pain. A psychologist asked people with chronic pain from four U.S. cities—San Diego, Nashville, Boston, and Worcester, Massachusetts—about their experiences. Two-thirds of them said the weather affected their pain, and they often felt it before the weather actually changed. Other studies have also found that people with joint pain might feel worse during severe weather changes, like when it rains.
It’s important to know that weather changes don’t make arthritis worse; they just temporarily affect how it feels. Some experts are still unsure if there’s a real connection between weather and joint pain. For example, a study from the 1990s looked at 18 people with rheumatoid arthritis and found no link between their pain and the weather. The researcher thought it might be more about how people perceive pain rather than the weather itself.
On the flip side, some scientists believe there’s a scientific reason for this connection. The main theory involves something called barometric pressure, which is the weight of the air around us. Our joints have special receptors that can sense changes in this pressure. When the pressure changes, the fluid in our joints might expand, causing swelling. This can make sensitive joints rub against muscles and nerves, leading to more pain.
Arthritis affects different parts of the joint, like the lining and ligaments, which have lots of nerve endings. This makes them sensitive to swelling. People without arthritis usually have more cartilage to cushion their joints, so they might not feel these changes as much.

Keep a journal for two weeks where you record the daily weather conditions and any joint pain you experience. At the end of the period, analyze your entries to see if there’s any correlation between the weather and your joint pain. Share your findings with the class.
Create a simple barometer using a jar, a balloon, and a straw to measure changes in air pressure. Observe how the straw moves with changes in pressure and discuss how these changes might affect joint pain. Relate your observations to the concept of barometric pressure affecting joint pain.
Divide into two groups. One group will argue that weather affects joint pain, while the other will argue against it. Use evidence from studies mentioned in the article to support your arguments. This will help you understand different perspectives on the topic.
Interview a family member or friend who experiences joint pain. Ask them about their experiences with weather-related pain. Compare their responses to the information in the article and discuss any similarities or differences with your classmates.
Work in groups to create a short educational video explaining why some people feel joint pain when it rains. Use visuals and simple explanations to make the science behind it easy to understand. Share your video with the class.
Sure! Here’s a sanitized version of the transcript:

Hi, I’m Craig, and this is Mental Floss on YouTube. Today, I’m going to answer a big question: Why do my joints hurt more when it rains? Many people with arthritis have noticed joint pain during weather changes. Experts still aren’t sure if this is a consistent or real phenomenon, but there’s some research on it, and I’m going to discuss it with you today.
In a study published in the journal *Pain*, a psychologist surveyed people with chronic pain in four different U.S. cities: San Diego, Nashville, Boston, and Worcester, Massachusetts. He found that two-thirds of patients claimed that the weather impacted their pain, and they reported feeling these effects before the weather itself changed. Other studies have concluded that people with joint pain are affected by severe weather changes, including rain.
It’s important to note that changes in weather don’t alter the severity of arthritis; they just temporarily affect the symptoms. However, some experts remain skeptical about the connection between weather and chronic pain. They argue that this phenomenon has been studied for a long time, yet no researcher has found a definitive objective relationship between joint pain and extreme weather. For instance, a study conducted in the mid-’90s examined 18 people with rheumatoid arthritis and found no connection between the two. The professor who designed the study believed the phenomenon was largely psychological, and many claims about joint pain and weather are based on anecdotal evidence.
On the other hand, some experts insist that there is scientific evidence supporting the relationship between joint pain and weather changes. The prevailing theory is that barometric pressure causes the pain. Barometric pressure refers to the weight of the atmosphere at a given moment. Everyone’s joints have receptors that are sensitive to changes in barometric pressure. When this occurs, the fluid in the tissue may expand, leading to swelling that causes sensitive joints to rub against muscles and nerves, resulting in increased discomfort.
Arthritis affects every part of the joint, including the joint lining and ligaments, which have many nerve endings, making them sensitive to swelling. Experts believe this sensitivity occurs in everyone, but people without arthritis tend to have more cartilage protecting their joints, making them less sensitive to these changes.
