We surely all know that water is essential for health. It plays many important roles, such as helping regulate body temperature, maintaining blood concentration, and transporting nutrients through cells. Not getting enough water can lead to health issues such as dizziness, lightheadedness, low blood pressure, ringing in the ears, and difficulty moving.
How Do You Know How Much Water You Should Drink Each Day?
This is a question that seems simple but not everyone answers it correctly. In particular, many people are interested in how to drink water the right way, and how drinking water can help with weight loss and longevity.
Many scientific studies have been conducted over the years. But each individual's water needs depend on many factors, such as your health condition, your activity level, and where you live. There is no single formula that suits everyone. However, knowing more about the body's fluid needs will help you estimate how much water you should drink each day.
What Are the Health Benefits of Water?
Water is the body's main chemical component, making up about 50% to 70% of body weight. Your body depends on water to survive. Every cell, tissue, and organ in the body needs water to function properly.
Removing waste through urination, sweat, and bowel movements
Regulating your normal body temperature
Lubricating joints
Protecting sensitive tissues
Lack of water can lead to dehydration – when you don't have enough water in your body to perform normal functions. Even mild dehydration can drain your energy and make you tired.
So How Much Water Does Your Body Need?
Every day you lose water through breathing, sweating, urination, and bowel movements. For your body to function well, you must replenish water by consuming beverages and foods that contain water.
How much fluid does the average healthy adult living in a temperate climate need? The recommendation is that everyone should drink 8 glasses of water (equivalent to 2 liters) a day.
Most healthy people can keep their bodies adequately hydrated by drinking water whenever they feel thirsty. For some people, less than eight glasses a day may be enough. But others may need more than that, depending on their goals, such as drinking water to stay young or to support weight loss.
You may need to adjust your total water intake based on a few factors, such as:
Exercise: If you engage in activity that makes you sweat continuously, you need to drink more water to compensate. Drinking water before, during, and after exercise is very important.
Environment: Hot or humid weather can make you sweat and need to replenish water right away. Dehydration can also occur at high altitudes.
Overall health: The body loses water when you have a fever, vomiting, or diarrhea. Drink more water or, as recommended by your doctor, drink rehydration solutions.
Other conditions that may require increased water intake include bladder infections and urinary tract stones.
Pregnancy and breastfeeding: If you are pregnant or breastfeeding, you may need extra water.
How Should You Drink Water to Lose Weight?
Scientific experts and sports coaches have also put forward many conflicting viewpoints.
In a 2009 obesity study published by the National Center for Biotechnology Information (USA), scientists observed and analyzed the diet and exercise habits of nearly 200 women aged 20-50 over a 12-month period. The survey results showed that women in the overweight group (BMI > 25) all drank less than 2 liters of water per day. This water intake included plain water, soft drinks, water in food, and fruits.
Another expert review published by the National Center for Biotechnology Information (USA), summarizing the results of trials on the effects of water on weight loss, also found that people who lost between 0.4kg and 8.8kg over 1-6 months had increased their water intake, replaced high-calorie beverages with plain water, and drank water before meals. This is strong evidence that drinking water can help you lose weight, especially when combined with other weight-loss strategies such as reducing calorie intake and exercising.
If you are interested in beauty, weight loss, or extending your lifespan, drinking water the right way is also an important deciding factor.
Water is necessary for living longer because it helps the body eliminate toxins, maintain normal blood pressure, transport nutrients, balance electrolytes, and boost metabolism. Drinking enough water every day can improve how your body functions and increase your lifespan in the long run.
According to the Mayo Clinic, about 50% to 70% of your body is made up of water. It helps protect your spinal cord, lubricates and cushions your joints, and ensures your body maintains a normal temperature. Getting the right kind of water also increases calcium and magnesium intake, helping keep bones strong. Many studies have shown that mineral water not only promotes bone health but also benefits digestion.
