How Watching International Football Affects the Body
觀看國際足球賽對身體的影響
Introduction
Researchers from the University of South Wales carried out a study to find out how watching a high-pressure football match affects human health.
南威爾斯大學的研究人員進行了一項研究，旨在了解觀看高壓力的足球賽事如何影響人類健康。
Main Body
The researchers used biometric tools to monitor a person during a World Cup match between England and Croatia. They used ultrasound to measure blood flow in the brain, respiratory devices to check carbon dioxide levels, and saliva tests to measure cortisol, which is a stress hormone. To make sure the results were accurate, the subject did not drink any alcohol, as this would have interfered with the data.
研究人員使用生物識別工具，在英格蘭與克羅埃西亞的世界盃賽事期間監控一名受試者。他們使用超音波測量腦部血流，使用呼吸裝置檢查二氧化碳水平，並透過唾液測試測量壓力荷爾蒙——皮質醇。為了確保結果準確，受試者未飲用任何酒精，因為這將會干擾數據。
The results showed a clear stress response during the most exciting parts of the game. For example, when a penalty goal was scored, the subject's heart rate jumped from 54 to 69 beats per minute in just half a second. Furthermore, blood pressure increased and blood flow to the brain decreased because the person was breathing too quickly. By the end of the match, cortisol levels had risen from 4.19 nmol/L to 5.15 nmol/L.
結果顯示，在比賽最激烈的片段中，身體有明顯的壓力反應。例如，當射入罰球時，受試者的心率在短短半秒內從每分鐘 54 次跳升至 69 次。此外，由於受試者呼吸過快，導致血壓升高且腦血流量減少。到比賽結束時，皮質醇水平從 4.19 nmol/L 升至 5.15 nmol/L。
Professor Damian Bailey explained that these reactions are like a 'fight-or-flight' response, which can be similar to light exercise for healthy people. However, he emphasized that not everyone reacts the same way. While the person in this study was healthy, Professor Bailey asserted that people with heart or brain conditions could face serious risks. For instance, high blood pressure and thicker blood could cause a heart attack or lead to fainting.
Damian Bailey 教授解釋，這些反應就像「戰或逃」反應，對於健康的人來說，與輕微運動類似。然而，他強調並非每個人的反應都相同。雖然本研究中的受試者很健康，但 Bailey 教授斷言，患有心臟或腦部疾病的人可能會面臨嚴重風險。例如，高血壓和血液黏稠度增加可能會導致心臟病發或昏厥。
Conclusion
The study concludes that while moderate stress from sports can be harmless or even helpful for healthy people, it can be very dangerous for those with existing medical problems.
研究結論指出，雖然運動帶來的適度壓力對健康的人來說無害甚至有益，但對於已有醫療問題的人來說，則可能非常危險。

⚡ The 'B2 Shift': From Simple to Sophisticated Linking
At an A2 level, you likely use and, but, and because to connect your ideas. To move to B2, you need Connectors of Logic. These words don't just join sentences; they tell the reader how the ideas relate.
🔍 Analysis of the Text
Look at how the author moves from a fact to a consequence or an addition:
- "Furthermore..." (Used instead of and). This signals that the author is adding a new, important piece of evidence to a list.
- "However..." (Used instead of but). This creates a professional contrast between two opposing ideas (healthy people vs. sick people).
- "For instance..." (Used instead of like). This is the academic way to introduce a specific example.
🛠️ The Upgrade Path
If you want to sound more like a B2 speaker, swap your basic words for these high-impact alternatives found in the article:
| A2 Word | B2 Upgrade | Context from Article |
|---|---|---|
| And | Furthermore | Furthermore, blood pressure increased... |
| But | However | However, he emphasized that... |
| For example | For instance | For instance, high blood pressure... |
💡 Pro Tip: The Comma Rule
Notice that Furthermore, However, and For instance are all followed by a comma ( , ).
When you start a sentence with these transition words, the comma acts as a small 'breath' for the reader, making your writing feel structured and controlled rather than rushed. This is a hallmark of B2 fluency.
