Weather plays an important role in our lives. It affects our daily activities, what we wear, the crops we can grow and eat, and our travel plans. Weather also affects our bodies. Some obvious examples would be heatstroke and frostbite as a result of extreme temperatures. Interestingly, there are a variety of other effects that our body experiences due to subtle changes in season, atmospheric pressure, temperature, and relative humidity. Scientists have found weather effects on headaches, moods, strokes, trauma, kidney stones, and arthritis. These effects represent just a few of many, as investigating weather effects on the human body is an ongoing research subject.
