Drinking water, put simply, keeps you hydrated. Your body is made up of 60-70% water. Drinking water helps digestion, the regulation of body temperature, and the transport of nutrients to your muscles, organs and all other areas of the body. Dehydration can cause a variety of symptoms, including chronic muscle or joint pain, lower back pain, headaches as well as constipation.
Every day, the body naturally loses water through processes such as perspiration, urination and respiration. Even before you are thirsty, your body may be in need of water.
Water is also linked to healthy weight loss. Studies have shown that people who drink more water daily lose weight more easily and are statistically at a healthier weight.
People who lead active lifestyles should drink more water than those who are more sedentary.
