Hydration refers to the process of adding water to the body to maintain an adequate fluid balance with drinking being the primary way to hydrate the body. Adequate hydration is essential for good health and can help maintain normal bodily functions such as regulating body temperature, transporting nutrients and oxygen to cells, removing waste, lubricating joints and protecting sensitive tissue. Water is also necessary and plays a significant role in athletic performance, muscle function, energy production, production of saliva, which aids digestion, and for the maintenance of healthy skin. Dehydration can lead to many health issues such as fatigue, headaches, dizziness, constipation, dry skin, and even more severe conditions like kidney damage, heat exhaustion and heatstroke. Consumption amounts of water are dependent on the individuals needs which can vary depending on factors such as age, weight, physical activity level, and climate. Overall, it is essential to drink enough water to maintain adequate hydration and support optimal health and performance, with a general recommendation to drink at least eight 8-ounce glasses (8 cups) of water per day, although individual needs may vary.
