there is something very special about spring.everyone suddenly starts feeling happy and energetic.poets have written about this strange occurrence for centuries.they call it spring fever.students show symptoms such as being full of energy and an inability to focus on school work.people also tend to feel more romantic. however, spring fever is not an actual illness.it simply refers to the improved mood and increased energy people have as the weather gets better.our bodies do change in spring as well.first, our brains stop producing a chemical that makes us feel tired.our mood also improves as we get a boost of vitamin d from sunlight.second, we start becoming more active, and the increase in activity affects both our body and our mood.all these things contribute to the good feelings we have in spring.
