Why Hydration Matters
Water plays a critical role in almost every system in your body, from regulating temperature and flushing toxins to supporting digestion and joint health. Despite this, many people still don’t drink enough water throughout the day.
Staying hydrated isn’t just important during the summer or while exercising — it’s a daily necessity for your body to function properly.
How Much Water Should You Drink Daily?
There’s no one-size-fits-all answer, but a common guideline is to drink:
- Women: around 2.0 – 2.5 litres per day
- Men: around 2.5 – 3.0 litres per day
- More if you’re physically active, breastfeeding, or in hot climates
- Less for some older adults or people with certain health conditions
Remember, your needs can change based on factors like weather, activity levels, or illness.
Tip: Don’t wait until you’re thirsty to drink — thirst is a sign you’re already mildly dehydrated.
Signs You May Be Dehydrated
It’s easy to overlook the symptoms of dehydration, especially if they appear gradually. Here are a few signs your body may be running low on fluids:
- Dry mouth or lips
- Headache or dizziness
- Fatigue or lack of concentration
- Dark yellow or strong-smelling urine
- Reduced urination frequency
If you notice these signs, it’s a good idea to increase your fluid intake gradually throughout the day.
Best Ways to Stay Hydrated
Plain water is the gold standard, but there are many ways to stay hydrated:
- Carry a reusable water bottle to remind yourself to sip throughout the day
- Add natural flavor with lemon, cucumber, or mint if you find plain water boring
- Eat hydrating foods like watermelon, cucumber, oranges, and strawberries
- Set phone reminders or use hydration apps to track your intake
- Limit dehydrating drinks like alcohol or caffeine
Does Tea or Coffee Count? Yes — drinks like tea, herbal infusions, and even coffee do contribute to your fluid intake, though water is always best for pure hydration.
When to Be Extra Cautious
Some groups are more at risk for dehydration and may need to monitor their fluid intake more closely:
- Children and older adults
- Pregnant or breastfeeding individuals
- People with chronic illnesses, such as diabetes or kidney issues
- Athletes or people working outdoors in the heat
If you’re unsure about how much water is right for you, speak with a healthcare provider.
