Introduction
Staying hydrated is one of the simplest yet most powerful ways to maintain good health. Water makes up about 60% of our body weight and plays a crucial role in nearly every bodily function. From digestion to brain function, hydration is key to keeping your body running smoothly.
In this article, we’ll explore why staying hydrated is so important, the signs of dehydration, and practical tips to ensure you drink enough water every day.
Why Is Hydration Important?
Water is essential for:
1. Regulating Body Temperature – Sweating helps cool you down, especially during exercise or hot weather.
2. Supporting Digestion – Water helps break down food and prevents constipation.
3. Flushing Out Toxins – Kidneys need water to filter waste through urine.
4. Lubricating Joints – Hydration keeps joints flexible and reduces stiffness.
5. Boosting Brain Function – Even mild dehydration can cause headaches, fatigue, and poor concentration.
6. Maintaining Healthy Skin – Proper hydration keeps skin moisturised and reduces dryness.

Your body gives clear signals when it needs more fluids. Look out for:
Dark yellow urine (light yellow or clear is ideal)

If you experience these symptoms often, you may need to increase your water intake.
How Much Water Should You Drink?
The common recommendation is 8 glasses (about 2 litres) per day, but individual needs vary based on:

A simple rule: Drink when you’re thirsty, and sip water throughout the day.
