The benefits of drinking water on our bodies
Why is water essential for our health?
Our bodies are made up of about 60% water which keeps every system in the body functioning properly by:
- flushing waste from the body
- keeping body temperature steady
- helping brain function
- Aiding digestion
- Preventing constipation
- Carrying nutrients and oxygen to your cells
- Maintaining electrolyte balance
- Normalising blood pressure
- Stabilising the heartbeat
- Cushioning joints
- Protecting organs and tissues
We get most of our water from drinking beverages, but water-rich food such as salads and fruit, also contribute a small amount to our daily water intake.
How much water?
For many years the “accepted” wisdom is that we should drink between 6 – 8 glasses a day. However, recent research from the Harvard Medical School suggests “four to six cups” a day for healthy adults, and all beverages count, even coffee, cordial mixers, and tea. Of course, pure water is always the better choice. Sugary and alcoholic drinks can lead to weight gain and inflammation, increasing your risk for developing diseases such as diabetes, while caffeine can cause anxiety or sleeplessness.
The reality is that water intake should be individualized, and how much you need to drink depends on how active you are, the weather, and your physiology. On very hot days, or if you exercise and perspire heavily, you will obviously need to drink more, say 2 – 3 cups every hour or more. Check your thirst levels; feeling thirsty is a sign that you need to hydrate. Pale or non-coloured urine typically indicates proper hydration, while dark-coloured indicates dehydration. Other warning signs of dehydration include weakness, headaches, low blood pressure, dizziness, and confusion.
Too much?
Drinking too much water can also be dangerous, causing imbalanced electrolytes in the body which disrupts brain function. If you have health problems such as thyroid, liver, kidney, or heart disease; or if you’re taking medications that cause water retention such as non-steroidal anti-inflammatory drugs, opiate pain medications, and some antidepressants, check with your doctor if you are not sure how much liquid is safe or contact LifeAssist.
