Cold weather can have a significant impact on our bodies, even at seemingly mild temperatures. A recent experiment conducted at 10 degrees Celsius revealed the physiological challenges that cold homes can pose to our health. This is particularly relevant as 10 degrees Celsius is the average temperature that people living in unheated homes may experience due to financial constraints. The experiment showed that even at this temperature, the heart, lungs, and brain are profoundly affected.

The experiment took place in an environmental chamber, where scientists could control the temperature, humidity, and oxygen levels. The participant, in this case, the author of the article, was wired up to various monitors to track body temperature, heart rate, and blood pressure. As the temperature dropped from a comfortable 21 degrees Celsius to 10 degrees Celsius, the body’s response became evident. Sweating stopped, hairs stood up to insulate the body, and blood vessels in the hands constricted to preserve warmth for critical organs.

The effects of cold weather on the body were further demonstrated by the participant’s muscle shivering and the changes in blood flow to the brain. The brain received less oxygen and glucose, negatively impacting cognitive function. However, the body’s main goal of maintaining core body temperature remained intact, albeit with increased effort. The heart had to work harder, pumping warm blood more intensely, and blood pressure increased, posing a risk for stroke and heart attack.

It is important to recognize the dangers associated with cold weather, as evidence suggests that cold is more deadly than heat. Cold weather also favors the spread of viruses, such as the flu, and increases the risk of infections like pneumonia. Indoor gatherings with closed windows and lack of fresh air create an environment conducive to virus transmission. Additionally, cold air affects the immune system’s response in the nose, allowing viruses to thrive.

To mitigate the effects of cold weather, it is recommended to focus on insulation through appropriate clothing, such as wool garments. Gloves and warm socks are more important than a hat, although a woolly hat can also help. A higher carbohydrate diet can generate more body heat, and staying active rather than sedentary can also help maintain warmth. Overall, it is crucial to be aware of the impact of cold weather on our bodies and take necessary precautions to stay healthy.

Group or Classroom Activities

Warm-up Activities:

– News Summary
Instructions: Have students read the article and then summarize the main points in their own words. They should focus on the impact of cold weather on the body and the recommended precautions to stay healthy. They can share their summaries with a partner or in small groups.

– Opinion Poll
Instructions: Divide the class into pairs or small groups. Have them discuss and share their opinions on the following question: “Do you prefer cold weather or hot weather? Why?” Each group should take a poll within their group and report back to the class with the results, explaining the reasons behind their preferences.

– Vocabulary Pictionary
Instructions: Prepare a list of vocabulary words from the article, such as physiological, constraints, insulate, immune system, etc. Divide the class into teams and give each team a word. They must draw a picture to represent the word and have the other teams guess what the word is. This activity will help reinforce the vocabulary from the article.

– Pros and Cons
Instructions: Divide the class into two groups. Assign one group to discuss the pros of cold weather, while the other group discusses the cons. Give them a few minutes to brainstorm their ideas and then have them present their arguments to the class. Encourage respectful debate and allow for open discussion.

– Future Predictions
Instructions: In pairs or small groups, have students discuss and make predictions about the future of cold weather and its impact on our bodies. They can consider factors such as climate change, technological advancements, and societal changes. Each group should present their predictions to the class and explain their reasoning.
