Water is an essential component for the survival of all living organisms. It is the most abundant molecule in the human body, making up 65% of an adult’s body weight. Water carries nutrients and hormones through the body, regulates body temperature, cushions joints, and lubricates eyes. The body loses around 2.5 liters of water every day through urine, breathing, sweating, and pooping. Therefore, it is crucial to replenish the lost fluids by drinking water or other fluids that contain water.
Thirst is a survival instinct that is regulated by the hypothalamus in the brain. The hypothalamus monitors the amount of sodium and other substances in the body and creates the urge to drink when the body needs fluids. If the body is unable to satisfy its thirst, it may lead to dehydration. The initial signs of dehydration include a dry mouth, darker urine with a stronger odor, and decreased brain function, including slower response time and decreased ability to feel pain. The brain tissue literally shrinks when dehydrated, making the same task require more brain power and oxygen.
After a day or two without fluids, the body stops producing urine, and the person may suffer from muscle spasms, trouble swallowing, and nausea. When the body lacks fluids for an extended period, it may lead to seizures and organ failure. In severe cases, the brain may also shut down, leading to delirium and impaired brain function. It is crucial to stay hydrated to avoid these dangers.
More than 783 million people on earth do not have access to clean water. As our personal drinking sources become increasingly contaminated, scientists are trying to find solutions to this problem, such as removing salt from ocean water, tapping into underground aquifers, and creating innovative water filtration systems. Small investments can make a huge difference, and many water charities, such as Water.org and UNICEF, have fantastic initiatives that you can contribute to.
One such water charity project is in Morocco, which is helping to bring clean and safe water to five villages in the area. Before this project, many of the villagers had to walk miles to get contaminated water that posed a risk to their health. But now, thanks to the project, they have access to clean water, which has significantly improved their quality of life. It has allowed them to focus on other aspects of their lives, such as education and economic opportunities. These projects are making a huge difference in the lives of people who lack access to clean water, and we should support them in any way we can.

By working together, we can end the global thirst crisis.
For one week, keep a diary of your water consumption. This includes not only the water you drink, but also the water you use for bathing, cooking, and cleaning. At the end of the week, calculate your total water usage and reflect on ways you could reduce your water footprint.
Create an informative poster about the dangers of dehydration. Include the signs of dehydration, why it’s dangerous, and how to prevent it. You can use drawings, diagrams, or any other visual aids to help convey your message.
Research a water charity of your choice. Find out what projects they’re currently working on, who they’re helping, and how they’re making a difference. Write a one-page report summarizing your findings and share it with the class.
Conduct a simple water filtration experiment at home or in the classroom. You can use materials like sand, gravel, and activated charcoal to create a homemade water filter. Test the filter with dirty water and observe the results. Remember, do not drink the filtered water as it may still contain harmful bacteria or chemicals.
Organize a class debate on potential solutions to the global water crisis. Split into teams and each team will research and argue for a different solution, such as desalination, tapping into underground aquifers, or innovative water filtration systems. At the end of the debate, hold a class vote to decide which solution is the most feasible and effective.
