Most of us, if not all, know that the human body comprises around 60% water. According to the Harvard School of Public Health, drinking enough water each day is crucial for many reasons: to regulate body temperature, keep joints lubricated, prevent infections, deliver nutrients to cells, and keep organs functioning properly. Being well-hydrated also improves sleep quality, cognition, and mood.
Larry Kenney, PhD, a professor of physiology and kinesiology at Penn State, stated that hydration is important because the body is composed mostly of water, and the proper balance between water and electrolytes in our bodies really determines how most of our systems function, including nerves and muscles.
Meanwhile, the Institute of Medicine recommends that women must aim to consume 2.7 liters (or 91 ounces) of fluids daily, and men to drink 3.7 liters (or 125 ounces). But that recommendation doesn’t focus on water specifically. Rather, it includes all fluids and water-rich foods, including fruits, vegetables and soups. According to Joe Leech of Healthline, drinking enough water helps maximize physical performance. If you don’t stay hydrated, your physical performance can suffer. This is particularly important during intense exercise or high heat. Losing as little as 2% of your body’s water content can significantly impair your physical performance.
Deficient amount of water in our body also significantly affects energy levels and brain function. Your brain is strongly influenced by your hydration status. Studies show that even mild dehydration, such as the loss of 1–3% of body weight, can impair many aspects of brain function. In addition, drinking water may help reduce headaches and headache symptoms. However, more high-quality research is needed to confirm this potential benefit. It may also help prevent and relieve constipation, especially in people who generally don’t drink enough water. Furthermore, increased water intake appears to decrease the risk of kidney stone formation.
Water is really important to keep us going. Even mild dehydration can affect you mentally and physically. Hence, you should ensure that you get enough water each day. It’s one of the best things you can do for your overall health.
