The amount and frequency of water intake varies for each individual depending on factors such as age, gender, health, physical activity, climate, and overall hydration needs. However, a general guideline is to consume at least 8 glasses (64 ounces or about 2 liters) of water per day, which is known as the "8x8 rule." It is also important to listen to your body's cues for thirst and drink water accordingly. Additionally, consult with a healthcare professional for personalized advice based on your specific needs.
