Lifestyle News: We have always heard that water is life. The world cannot be imagined without water. Water is essential for every living being, from humans to the earth. Experts always say that everyone should drink 2 to 2.5 liters of water a day, which is equivalent to about 8 to 10 glasses. It also depends on the individual's body as to how much water he needs in a day. But normally this amount is considered appropriate. This helps in keeping the body hydrated and you feel energetic throughout the day. Nowadays, people do a lot to keep their body hydrated. They make various types of drinks a part of their diet.

To stay hydrated during the summer, we often include water-rich foods in our diet and drink detox drinks. It's said that this helps keep the body hydrated and overall healthy. But do we really need to include more than just water in our diet to stay hydrated? Isn't 2.5 liters of water enough? If this question comes to your mind, let's hear the expert's opinion.

Is 2.5 liters of water enough to keep the body hydrated?

Dr. Rohit Sharma, Internal Medicine Consultant at Apollo Spectra Hospital, explains that drinking just 2.5 liters of water a day is generally considered sufficient to keep the body hydrated, but this varies depending on each individual's body and needs. Your body weight, age, weather, medical conditions, and how active you are during the day determine how much water you should drink. For example, drinking more water during the summer is recommended.

Additionally, people who engage in high-intensity workouts, active schedules, or heavy lifting require more water. In addition to water, fruits, vegetables, and other foods also help keep the body hydrated. Therefore, drink water according to your body's needs and needs. If you experience excessive thirst and reduced urine output, consult a specialist.

Is detox drink water necessary?

Experts explain that detox drinks aren't necessary because our bodies are capable of eliminating toxic substances on their own. This is primarily done through the gastrointestinal system and liver, which effectively eliminate toxic elements. Eating a healthy and balanced diet, drinking adequate water, exercising regularly, and maintaining a clean body are essential for maintaining a healthy body.

Detox drinks are said to help promote health and weight loss, but their benefits haven't yet been fully scientifically proven. If you're interested in taking any type of detox drink, consult an expert. They will be able to provide appropriate advice based on your health and needs.

How much water should one drink?

Experts explained that drinking 2 to 3 liters of water a day is considered ideal for a normal person. However, the appropriate amount of water intake per day is determined based on each person's age, weight, lifestyle, medical condition, and other factors. If you live in a hot climate or engage in increased physical activity, your water needs may increase. Drinking too little water can lead to dehydration, leading to fatigue, headaches, dry skin, and urinary problems.

What happens if you drink too much water?

Drinking more water than your body needs can also be detrimental to your health. This can lead to electrolyte imbalances, which can lead to weakness, vomiting, or, in severe cases, heart problems. Therefore, it's best to be mindful of your thirst and drink water at regular intervals. Furthermore, if you have a health condition, such as kidney problems, consult a specialist about how much water is appropriate for you in a day.
