Đề thi VSTEP Reading B1 — Daily Hydration Habits

Many people don't drink enough water during the day. The human body is about 60% water, and we lose water through breathing, sweating, and going to the bathroom. When we don't replace this lost water, we can feel tired, get headaches, and have trouble concentrating. Doctors recommend that adults drink about 2 liters of water every day, but the amount each person needs depends on several factors. People who exercise a lot or live in hot climates need more water than those who sit in air-conditioned offices. The best way to stay hydrated is to carry a water bottle and take small sips throughout the day. Waiting until you feel thirsty is not ideal, because by that time your body is already a little dehydrated. Eating fruits and vegetables with high water content, like watermelon and cucumber, can also help you stay hydrated. Many schools and offices now place water coolers in hallways to encourage people to drink regularly.
