Infants and children tend to have higher body water percentages than adults. The amount of water in your body decreases as you age because of age-related changes in body composition, hormones, and kidneys’ function.
Water is present in every cell, tissue, and organ in your body. The brain and heart are approximately 73% water, and the lungs are about 83% water. Muscles and kidneys are about 79% water, and skin is about 64% water. Even bones contain water, with a water content of around 31%.

Staying hydrated has numerous benefits and advantages. Water helps maintain body fluids, which in turn help regulate body temperature and keep the skin looking healthy and radiant. It also aids in digestion, helps transport nutrients throughout the body, and flushes out waste and toxins. Staying hydrated can also boost your immune system, improve cognitive function, and make you feel more energized.
On the other hand, dehydration can cause a host of problems and risks. Mild dehydration can cause fatigue, headaches, and dry skin, while severe dehydration can lead to organ failure and even death. Chronic dehydration can also increase the risk of kidney stones, urinary tract infections, and constipation. It can also hinder athletic performance and cause muscle cramps.

1. Do we need to drink eight glasses of water a day?
There is no one-size-fits-all answer to this question. The amount of water you need to drink may vary depending on your age, sex, weight, and activity level. The Institute of Medicine recommends that men consume about 3.7 liters (125 ounces) of water per day, while women consume 2.7 liters (91 ounces) of water per day. However, keep in mind that these recommendations include water from all sources, including food and beverage.
2. How can I tell if I’m dehydrated?
Common signs of dehydration include dry mouth, thirst, fatigue, dizziness, dark urine, and infrequent urination. Severe dehydration can cause confusion, rapid heartbeat, and even unconsciousness.
3. Does drinking caffeinated beverages like coffee and tea dehydrate you?
While caffeine is a diuretic, the amount of water in caffeinated beverages typically offsets the diuretic effect. So, moderate consumption of caffeine is unlikely to cause dehydration. However, excessive amounts of caffeine can cause dehydration.
