Staying Hydrated in Karachi
Urban hydration strategies for Pakistan's mega-city on the Arabian Sea.
Karachi, Pakistan's largest city and economic hub, faces significant hydration challenges due to its hot, semi-arid climate and dense urban environment. Located on the Arabian Sea coast, the city experiences high temperatures, especially during the summer months (April-October), often exceeding 100°F (38°C). High humidity levels exacerbate the effects of the heat, leading to increased sweating and fluid loss. Heatwaves are a recurring concern, posing serious health risks. Access to clean and safe drinking water can also be inconsistent across different areas of the city, requiring careful attention to water sources and hygiene practices.
