There are several signs that you may not be drinking enough water. These include dark urine, fatigue, headaches, and a sluggish digestive system.
These symptoms occur because the body lacks the fluids it needs to function optimally.
Water needs are not the same for everyone but depend, among other things, on weight, temperature, and activity level, according to the outlet Tua Saúde.
Digestion and absorption
Water plays a role in digestion. It helps the body break down food and absorb nutrients such as vitamins and minerals.

According to a review in Nutrition Reviews, fluid intake affects how the stomach and intestines function.
If the body lacks fluids, absorption may be reduced, which can lead to abdominal discomfort.
Practical recommendations
A common rule of thumb is to drink around 30 to 35 milliliters of water per kilogram of body weight per day.
For a person weighing 70 kilograms, this corresponds to approximately 2 to 2.5 liters daily.
