Experts agree on exact amount of water to drink daily to protect heart health

Water is vital for a healthy human body – it transports nutrients, keeps cells healthy, and helps to remove waste products from your system. We are constantly losing water from our bodies, primarily via urine and sweat.

With the sweltering summer heat upon us, it’s essential to stay hydrated for your health. Failing to drink sufficient water can lead to fatigue and lethargy, as water is crucial for maintaining a healthy human body.

Studies have highlighted the importance of water for both physical and mental well-being. It plays a key role in nutrient transportation, cell health, body temperature regulation, and waste removal.

While our bodies need water throughout the year, the requirement increases during hot weather. A doctor has now outlined the vital daily water intake necessary for your body and heart health, 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” matter. Dietician Ilyse Schapiro, speaking to the American Heart Association News, emphasised the significance of proper hydration for heart health.

The specialist remarked: “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 colour” of your urine, the better hydrated you are. Determining the exact amount of water you need depends on various factors such as age, weather conditions (whether it’s hot, humid, dry, or cold), your activity level, and whether you’re male or female.

Emergency medicine specialist Dr Michael Sayre, based at Harborview Medical Center in Seattle, stresses the importance of heeding your body and mind’s signals. While speaking to the American Heart Association News, he highlighted that adequate water intake can help ward off severe conditions such as heatstroke, reports Surrey Live.

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.”

Considering that human bodies consist of over half water – typically ranging from 55 to 78 percent for the average adult – staying hydrated proves crucial. The Food and Nutrition Board at the Institute of Medicine in the United States has offered guidelines on the optimal daily water intake, with different recommendations for men and women.

The guidance suggests that men require approximately 3.7 litres of water per day, which is around 15 glasses, while women should aim for about 2.7 litres, equivalent to roughly 11 glasses. Beyond drinking water, it’s noteworthy that many individuals obtain around 20 percent of their hydration through food consumption, particularly by eating fruits and vegetables.

Symptoms such as tiredness, headaches, dizziness, and a dry mouth could indicate dehydration, which can occur after intense exercise or prolonged exposure to heat. Interestingly, feeling thirsty may in fact be one of the later indicators of the need to replenish your body’s water supply.

Medication and specific illnesses, such as diabetes and heart disease, can influence an individual’s hydration needs. Schapiro highlighted that ‘high blood pressure and other types of medications tend to be diuretics’ – resulting in the body losing more water. She advised those on diuretic medicines to be mindful of maintaining hydration.

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