Why Do Schools Allow Students To Wear Uniforms

What is one thing to change in a schools dress code? How would that change affect everyone around you? I believe one change should be students ability to wear a hat because it gets very cold in the winter, not wearing a hat makes it easier to get sick, a hat would prevent us from getting sick as much. Here are three reasons why schools should change the dress code to allow students to wear hats.
One reason is because it gets very cold in the winter. We should get to wear hats because of the coldness when it rains, snows or very high powered winds. Car riders get out and have to walk in the cold. They have a higher chance to get sick. Here is two more reasons why students should be able to wear hats at school.
Secondly, hats are good because

it is very easy to get sick without them. It’s easier to get sick by more of students heads being uncovered in cold weather. We need to protect our brain from the cold and our ears from frostbite in the snowy weather. It’s also easier to the flu or pneumonia. Both pneumonia and the flu have caused people to die. Here is one more reason hats should be permitted in schools.
Finally, hats are important because they protect us from the cold, sickness, and keeps us dry in the winter rain. The diseases i talked earlier are deadly to younger people as well as adults. Hats would help us stay dry and healthy. Students would not get sick as often and would be able to learn better in school. That is the final reason hats should be allowed in schools and the dress code be changed.
Hats should be allowed in school because of cold weather , chances of getting sick is higher and they protect from illness. What is one thing you would change and how would it affect you?
