Water is essential for life, yet many people do not drink enough throughout the day. Proper hydration supports nearly every function in the human body, from regulating temperature to supporting digestion and cognitive function. Understanding your hydration needs is a fundamental aspect of maintaining good health.
The human body is approximately 60 percent water. Every cell, tissue, and organ depends on water to function properly. Water helps transport nutrients, flush waste products, cushion joints, and maintain blood pressure. Even mild dehydration of just one to two percent of body weight can affect physical performance and mental clarity.
How much water do you actually need? While the common advice of eight glasses a day is a reasonable starting point, individual needs vary. Factors such as body size, physical activity level, climate, and overall health all play a role. In Kenya's warm climate, especially during hot seasons, you may need significantly more than the standard recommendation.
Recognising the signs of dehydration is important. Early symptoms include thirst, dry mouth, dark yellow urine, fatigue, and headache. More severe dehydration can cause dizziness, rapid heartbeat, confusion, and fainting. Children and elderly people are particularly vulnerable and may not recognise thirst cues.
Electrolytes are minerals that carry an electric charge and are essential for various bodily functions. Sodium, potassium, calcium, and magnesium are the key electrolytes. They help regulate nerve and muscle function, maintain fluid balance, and support bone health. When you sweat, you lose both water and electrolytes.
During intense physical activity, hot weather, or illness involving vomiting or diarrhoea, plain water may not be enough. Oral rehydration solutions containing the right balance of water, salts, and sugar are the most effective way to rehydrate. These are readily available at MedCart pharmacies in convenient sachet form.
Sports drinks can be useful for athletes engaging in prolonged exercise but often contain excessive sugar. For everyday hydration, water remains the best choice. You can enhance your water intake by eating water-rich foods such as watermelon, oranges, cucumbers, and spinach.
Make hydration a habit by carrying a reusable water bottle, setting reminders to drink throughout the day, and starting each morning with a glass of water.
