1. Water Ensures Regular Functioning of Organs

Water is vital for the proper functioning of all organs in the body. The proper functioning of organs such as the cardiovascular system, respiratory system, digestive system, reproductive system, nervous system and kidneys depends on adequate water consumption[^3^]. In addition, drinking regular and sufficient water can prevent constipation and high blood pressure.

Water is also important for the proper functioning of the brain[^4^]. If there is not enough water in the body, problems such as lack of concentration, sluggish reflexes, short-term memory problems and anxiety can occur.

3. Water is Good for Headaches

Adequate water consumption can prevent headaches[^6^]. Research shows that one of the causes of headaches may be dehydration of the body.

4. Water Supports Kidney Health

Water has an important role in the proper functioning of the kidneys[^7^]. Adequate water consumption can reduce the risk of kidney stones[^8^] and prevent urinary tract infections[^10^].

Water is also important for skin health[^12^]. Adequate water consumption prevents skin dryness and improves skin elasticity.

6. Drinking Water Helps Weight Control

The benefits of drinking water are too many to count. Water plays an important role in every aspect of our lives and is indispensable for our health. So, don’t forget to drink enough water to meet your daily water needs.

Daily water requirement may vary depending on many factors. These factors include age, gender, climate, physical activity level and health status. However, as a general guide, the following recommendations are frequently mentioned by health authorities:

What is the daily water requirement? How many litres of water should be drunk per day.

General Water Requirement for Adults

  • Women: It is recommended that they consume about 2.7 litres (about 11 cups) of water per day. About 20 per cent of this amount can be obtained from food.
  • Men: It is recommended that they consume about 3.7 litres (about 15 cups) of water per day. About 20 per cent of this amount can be obtained from food.

These recommendations reflect the daily water requirements of the average adult. However, individual needs vary.

Water Requirements for Different Situations

  • Physical Activity: Those who exercise intensely should consume more water as they lose more water.
  • Weather Hot or humid weather increases the need for water because it causes the body to lose more water.
  • Health Status: Conditions such as fever, diarrhoea and vomiting cause water loss from the body. In such cases, it is important to consume more water.
  • Pregnancy and Breastfeeding: The bodies of pregnant and breastfeeding women need more water. It is recommended to consume an extra 0.3 litres (about 1 cup) of water per day during pregnancy and 0.7-1.1 litres (3-4 cups) of water per day during breastfeeding.

Factors Determining Water Requirement

  • Age
  • Gender
  • Physical activity level
  • Climate
  • Health status

Each individual has a different daily water requirement. Therefore, in addition to the general recommendations above, it is important to listen to your body’s signals, such as the feeling of thirst, and act accordingly. In addition, liquids consumed other than water and foods with high water content also help to meet your daily water needs.
