The adequate daily intake will depend on a few factors. Consuming a combination of water and different beverages adds to that daily intake count.
See the below factors for further explanation as to why the eight glasses per day principle shouldn’t be the standard.
Gender and Age
For women ages 19-30, an adequate intake of 2.2 liters (74 fl. oz), amounting to nine cups per day, is recommended. For men in the same age range, 3.0 liters (101 fl. oz) per day is suggested, which is equivalent to 13 cups.
Pregnant and breastfeeding mothers are required to consume more water to supply nutrients to their babies.
Pregnant women should drink 1.9 to 2.8 liters (64 - 96 fl. oz) of water daily, which equates to 8 - 12 cups. Breastfeeding mothers should have an ample intake of 3.8 liters (128 fl. oz) or 16 cups per day.
About six to eight cups or 1.4 to 2.0 liters (46 to 64 fl. oz) of water are sufficient for children and teenagers.
For adults ages 30 and above, it’s crucial for them to drink enough water as they are prone to more health problems. To combat these health issues, the elderly should consume 1.7 liters (57.5 fl. oz) or 7 cups of water each day.
Certain health conditions like general fever or any illnesses that induce vomiting, loose bowel excretions, and excessive perspiration will lead to dehydration due to fluid loss. So make sure to drink water frequently to replenish your body with supplements and electrolytes.
Although water intake is needed to manage most kinds of illnesses, some kidney diseases require your healthcare provider’s advice on how much to consume.
Too much water can also result in an intoxication known as hyponatremia, which rarely occurs. When it does, those affected are usually athletes, diabetic people, and people who take certain medications.
People who stay in hot and humid environments are prone to being more thirsty and sweaty, which means they need a higher water intake to make up for the lost hydration in their bodies. Not drinking enough water in these environments can lead to severe dehydration or heat stroke.
Even though sweating isn't as common in colder places, you should still stay hydrated throughout the day as water helps regulate our body temperature.
