Many people watching swimming competitions at the Olympic Games being hosted in France are wondering why swimmers wear "winter jackets" before their events. According to NPR, the search engine "Google" in the United States has seen a significant increase in inquiries about why swimmers wear these jackets before competing in the Olympics. The site noted that "the question has become widely discussed among social media users in the United States."
The article points out that wearing jackets before swimming competitions helps maintain a stable body temperature after warming up. Additionally, the magazine "Swimming World" stated that wearing jackets keeps swimmers’ muscles relaxed, flexible, and ready to move forcefully. The magazine explained that if muscles cool down, they become stiff and less responsive.
