Answers to frequently asked questions about water and hydration
Every day your body flushes out water through urine, sweat, breathing and other metabolic processes. If you don't drink enough water you will sooner or later begin to experience the symptoms of dehydration - headaches, fatigue and lack of concentration. Chronic dehydration can lead to poor water-salt balance, constipation and kidney stones. This is why a drinking regime is so important.
Is it really necessary to drink eight glasses a day? How much should you drink? How do I make myself drink water and what can I do if I don't like drinking? Can I wash down my food and can coffee/tea make up for the lack of fluids? What can I drink on a diet apart from water? These and other readers' questions are answered in this post.
- It is said that you should drink eight glasses of water daily. Is this true?
Water needs are individual. Eight glasses was invented so that people could increase their water intake in a controlled manner by accustoming themselves to a drinking regimen. Similarly, the norm of 'two litres', although for a petite girl with a sedentary lifestyle, two litres may be a lot, while for a big guy athlete, two litres is too little.
Drinking water requirements are always higher for those who:
- Maintains an active lifestyle or/and works out;
- Are on a diet;
- Live in hot climates.
Body size also matters - larger people need more water. The need for water increases in summer and decreases in winter.
- How do you know what your body size should be?
According to the US Institute of Medicine (IOM), adults living in temperate climates need to drink daily:
- Men: 3.7 litres of fluid from all food sources, not just water;
- Women: 2.7 litres of fluids from all food sources.
To calculate your clean water needs, use the formula: weight in pounds * 0.55 = the right amount of water per day in ounces. This doesn't take into account your workouts, time of year, or goals. When it comes to your norm, it ranges from 2 to 3 litres, increasing in hot weather and on workout days.
- How do you get yourself to drink?
The easiest way is to develop a new habit. For a week, fill a two-litre bottle with water and don't part with it. Remember, you need more water in the morning than in the evening. Unless, of course, you have an evening workout. Over time, you will get used to this amount.
The second way is to drink 1-2 glasses before each meal and remember to drink when you feel thirsty, headache, tired, when you are in a bad mood.
A third way, set a timer or water balance app on your smartphone to establish a drinking regime.
- Can tea/coffee and other drinks make up for the lack of water?
Coffee and some types of tea without sugar or additives, yes, because they have no calories. But juice, borscht, porridge, fruit and some vegetables do not, because they contain water, but they are not water. They will help to compensate for the lack of liquid, but will not compensate for the lack of clean water. Author Ekaterina Golovina Foods provide about 20% of your total fluid needs. It is important to understand that food and drink are solutions, water is a solvent. Cells need water, not smoothies. In addition, drinks and foods contain calories, and if you're on a diet, quenching your thirst with kefir is not the best option.
- Can I drink it with a meal or/and right afterwards?
The myth that you can't drink with food and/or right after a meal has no scientific basis. On the contrary, your body needs water to digest and digest your food. It improves the transport of food through the oesophagus to the stomach, helps to digest large chunks of food and makes it easier for enzymes and acids to reach the food. Drink whenever you want.
- What can I drink on a diet apart from water?
Whatever you want, as long as these drinks fit into your calorie and GI needs. However, remember that liquid calories are better and easier to digest. While eating solid foods wastes calories for your body to digest them, liquids do not. Abusing liquid calories on a diet can have a negative impact on the rate of weight loss.
You can make water tastier by adding lemon, mint or berries to it. You can safely drink tea, herbal concoction and coffee. They have no calories as long as you drink these drinks without sugar or additives.
- Is it true that coffee has a diuretic effect?
No. That's a common myth, which Dr. Lawrence Armstrong of the University of Connecticut disproved in his study. His study showed that the diuretic effect of drinking coffee is the same as that of water. So coffee does not cause dehydration, and to date there is no scientific evidence to the contrary.
