‘I’m a doctor and this is how much water you need to drink daily for a healthy heart’

Water is essential for the human body to survive – but people don’t always know how much they should drink – now, a doctor has detailed the exact amount needed every day to stay healthy

The scorching summer heat can make you parched, but it’s essential to stay hydrated for your health. Failing to drink enough water can lead to fatigue since water is critical for a healthy human body.

Studies have underscored the importance of water for both physical and mental health. It’s a key player in nutrient transport, cell health, temperature regulation, and waste removal from the body. Our bodies need water throughout the year, and it’s especially important during hot months when you should increase your intake. A doctor has now outlined the vital daily water requirements for your body and heart, noting that it varies based on gender and other factors.

A registered dietitian with practices in New York and Connecticut has shed light on the ‘complicated’ answer. Dietician Ilyse Schapiro spoke with the American Heart Association News about the significance of hydration and the precise amount of water necessary for heart health. The professional advised: “Don’t let yourself get to that point of dehydration, an obvious way to tell is the colour of urine. We don’t want to always talk about that, but it’s a good indicator.”

Schapiro also mentioned that the “clearer the color” of your pee, the better hydrated you are. Determining the exact amount of water you need depends on age, weather conditions (whether it’s hot, humid, dry, or cold), your activity level, and whether you’re male or female.

Emergency medicine expert Dr. Michael Sayre from Harborview Medical Center in Seattle emphasized the importance of heeding your body and brain’s signals. In a conversation with the American Heart Association News, he pointed out that staying hydrated can help ward off serious conditions like heatstroke.

Dr. Sayre remarked: “In terms of preventing heat stroke, it’s generally people who ignored the signals they were thirsty or couldn’t respond to them because they were physically impaired, or they were in an environment where they didn’t have access to water.”

Our bodies are predominantly composed of water, with the average human body ranging from 55 percent to 78 percent water content. The Food and Nutrition Board at the Institute of Medicine in the United States has provided guidelines for the appropriate daily water intake, which differs for adult men and women. They recommend about 3.7 liters per day for men, which is roughly equivalent to 15 glasses, while women should aim for about 2.7 liters, or approximately 11 glasses of water.

However, drinking water isn’t the sole method of maintaining hydration; many individuals obtain around 20 percent of their water intake through their diet, particularly by eating fruits and vegetables. Dehydration can set in after several hours of intense exercise or exposure to extreme heat, and feeling thirsty might actually be one of the last indicators of dehydration.

Symptoms such as fatigue, headaches, dizziness, or a dry mouth are all potential indicators of dehydration. Medications and specific health conditions, such as diabetes and heart disease, can influence an individual’s hydration needs.

Schapiro clarified that “high blood pressure and other types of medications tend to be diuretics” – which cause the body to lose more water. She emphasized that individuals on diuretic medications should be mindful of maintaining proper hydration, reports Surrey Live.

Water is a crucial component of nutrition, the expert further explained, noting that thirst can often be misinterpreted as hunger. Staying well-hydrated can even deter you from unnecessary snacking, as having sufficient fluid in your system is a vital part of daily nourishment.
