This page will answer your questions about the importance of drinking water.
What is the importance of drinking water?
Getting enough water every day is essential for health, as about 60% of the human body consists of water. Water plays a role in keeping all body systems functioning properly. Drinking water can prevent dehydration, which may cause unclear thinking, mood changes, overheating, constipation, and kidney stones. Water also contains no calories, so replacing sugary drinks with plain water can help reduce calorie intake. Drinking water helps the body to:
- Maintain a normal temperature.
- Protect the joints.
- Protect the spinal cord and other sensitive tissues.
- Eliminate toxins through urine, sweat, and bowel movements.
What are the misconceptions about drinking water?
- Drinking water during meals causes indigestion: In fact, drinking water with meals aids digestion and helps staying hydrated.
- Warm water is better than cold water: There is no scientific evidence that warm water is more beneficial than cold water. The temperature of the water is a personal preference and does not affect the process of hydration.
What are the risk factors for dehydration (inadequate water intake)?
When fluid loss exceeds fluid intake, dehydration occurs. Dehydration can cause headaches, dizziness, or problems with digestion. Mild dehydration may affect mood, memory, or the extent to which one can process information. These symptoms usually resolve once the body is rehydrated. Severe dehydration, however, may require medical attention, as it can lead to serious complications such as confusion, kidney failure, and heart problems.
There is also a condition called excessive dryness. Although uncommon, it can occur in athletes and individuals with certain medical conditions. Its symptoms are often similar to dehydration but may require medical care. For example, prolonged physical activities such as marathon races may increase the risk.
What are the ways to prevent dehydration (inadequate water intake)?
Here are some tips to help maintain adequate and continuous water intake to avoid dehydration:
- Carry a reusable water bottle at all times.
- Replace sugary drinks with water.
- Choose water when dining out.
- Serve water with meals at home.
- Add a flavor enhancer such as lemon or cucumber to the water.
