How Many Liters of Water Should You Drink Daily? Why Is It So Important?
The importance of water consumption starts from the functioning of our body at the cellular level. Thanks to water, each of our cells absorbs nutrients, carries oxygen and expels waste. To answer the question of how many liters of water should be drunk daily, it is first necessary to understand the roles that water plays in the body. For example, water directly affects metabolic rate; According to research, adequate water intake can increase basal metabolic rate by 3 to 30 percent, which is a huge advantage in weight control. A survey by the Turkish Dietetic Association indicates that 40 percent of adults in Turkey consume less than 1.5 liters of water per day, which seriously increases the risk of dehydration. Dehydration begins with losing 2 percent of body water, which causes decreased blood volume, increased heart rate, and even slowed brain function. Especially in the summer months, this risk is higher for those living in the Mediterranean and Aegean regions of Turkey because high temperatures increase water loss through sweating.On the e-Health platform, our users can create personalized wellness programs taking into account such environmental factors; For example, you can track your daily water intake and receive reminders through our mobile app. The importance of water consumption is not limited to physical health; It also has a great impact psychologically. The role of water in reducing anxiety and stress levels is explained by its support for the production of serotonin in the brain. One study shows that stress hormones are 15 percent lower in individuals who drink 2.5 liters of water a day. Additionally, water protects skin health; It increases elasticity and delays the signs of aging. It is known that 70 percent of dry skin problems are caused by insufficient hydration.

How Many Liters of Water Should You Drink Daily? Calculation Based on Individual Factors
Determining your daily water needs is a personalized process that cannot be reduced to a single formula. As a general rule of thumb, take your body weight in kilograms and multiply that by 30; The result gives your minimum daily water need in milliliters. For example, for an individual weighing 60 kilograms this would be approximately 1.8 liters, but this is just the starting point. The answer to the question of how many liters of water should be drunk daily varies depending on age, gender, activity level, climatic conditions and health status. The age factor is at the forefront; For children and teenagers, water needs may be 20 percent higher because the metabolism is faster. The recommended amount for children aged 4-8 is around 1.5 liters, because water supports bone and muscle development during growth periods. Although the need for water seems to decrease in the elderly due to the slowing down of kidney functions, conscious consumption is essential because the feeling of thirst decreases; For individuals over 65, aiming for 2 liters is ideal. In terms of gender, since men have more muscle mass, their water needs are 10-15 percent higher than women.During pregnancy and breastfeeding, women's water consumption should increase to 3 liters, because amniotic fluid and milk production require extra hydration. On the e-Health platform, our dietitians can prepare e-Prescriptions and e-Reports by taking these factors into account, and all data is stored securely in e-Pulse.
