Urbanization can negatively impact health through various environmental, social, housing, and lifestyle factors. As cities grow rapidly, problems emerge such as air and water pollution, natural resource depletion, and climate change. These environmental changes can lead to health issues like asthma, infections from contaminated water, and illnesses associated with extreme heat or cold. Overcrowding in cities exacerbates social problems including crime, violence, and stress-related diseases. Factors like poverty, lack of education, and limited access to healthcare or social services also impact urban residents' health. Migrants in cities face additional challenges of separation from family, increased work stress, and adjustment to new environments.
