Depending on factors like location, age, and sex, the average human is between 55-60% water. So what role does water play in our bodies, and how much do we actually need to drink to stay healthy? The water in our bodies works to adjust temperature, and to nourish(滋养) the brain and other body parts. Water isn't only in our blood. An adult's brain and heart are almost three quarters water, while lungs are 83% water. If we are mainly made of water, why do we still need to drink so much? Well, each day we lose two to three liters(升) through our sweat, urine(尿) and even just from breathing, which helps our bodies get rid of waste. While these functions are necessary to our survival, we need to compensate for the water loss. Keeping a balanced water level is essential to avoid dehydration(脱水), which can have bad effects on overall health. Dehydration is usually caused by over consumption of water in a short amount of time. It can cause obvious drops in energy, mood and blood pressure. In severe cases, it will cause headache, and even death. However, on a normal basis, maintaining a well-hydrated system is easy to manage for those of us who are fortunate enough to have access to clean drinking water. For a long time, it's commonly believed that we should drink eight glasses a day. Now the consensus is that the amount of water we need to imbibe depends largely on our weight and environment. The recommended daily intake varies from between 2.5-3.7 liters of water for men, and about 2-2.7 liters for women. While directly drinking water is the healthiest, coffee or tea can also be alternatives to make up for water loss. Water within food makes up about a fifth of our daily water intake. Fruits and vegetables like strawberries and cabbage are over 90% water, and can provide valuable nutrients as well. Drinking well also has various long-term benefits. Studies have shown that it can lower the chance of stroke(中风) and reduce the risk of certain types of cancer. No matter what it is, getting the right amount of liquid makes a healthy life. consensus n. 共识;一致的意见 imbibe v. 吸收;喝;接受(信息等);饮(酒等)
