The typical recommendation for daily water intake is about 64 ounces, which translates to roughly four 16.9-ounce bottles of water per day for basic hydration

. However, this amount varies based on several factors:

• Body weight: A good rule is to drink half your weight in ounces. For example, a 160-pound person would need about 80 ounces, or about 4.7 bottles of 16.9 ounces each

• Activity level: If you are physically active or exercise intensely, add 1 to 2 extra bottles to your daily intake to compensate for fluid loss through sweat

• Climate: Living in hot, dry, or high-altitude environments increases water needs, possibly requiring 5 to 7 or more bottles daily

• Diet: High salt, protein, sugar, caffeine intake or alcohol consumption also increase hydration needs

Health authorities like the Mayo Clinic and the U.S. National Academies recommend about 3.7 liters (about 125 ounces) for men and 2.7 liters (about 91 ounces) for women daily from all fluids, including water from food

. This corresponds to approximately 6 to 7 bottles of 16.9 ounces for men and about 5 bottles for women. In summary:

• Basic daily hydration: ~4 bottles (16.9 oz each)
• Active or warm climate: 5 to 6 bottles
• High sweat or intense exercise: More than 6 bottles

Adjust your intake based on personal factors like weight, activity, climate, and diet to stay properly hydrated
