Answer:
There are many environmental factors such as temperature or levels of pollen or polluted air during the competition.
Step-by-step explanation:
With high or very low temperatures, you have to dress properly to be able to perform well. An example is an athlete playing a game in Norway in November. The most logical thing is that temperatures are around 0 degrees, and to reduce the risk of injury, excellent warming is necessary, or wearing clothes to maintain body temperature.
Another example is athletes with allergies or respiratory problems, their performance may be affected due to a high amount of pollen or polluted air. It is essential to take into account pollen and air purity in training and competition places.
