Water improves physical wellbeing
Water Helps to Maximize Physical Performance
We already mentioned that hydration is vital. Losing as little as 2% of your body's water content can significantly impair physical performance. If we do not stay hydrated, physical performance can suffer. This is particularly important during intense exercise or high heat.
This can lead to altered body temperature control, reduced motivation, increased fatigue and make exercise feel much more difficult, both physically and mentally. Optimal hydration has been shown to prevent this from happening, and may even reduce the oxidative stress that occurs during high-intensity exercise. This is not surprising when you consider that muscle is about 80% water. So, if you exercise intensely and tend to sweat, then staying hydrated can help you perform at your absolute best. (18)
There are many other benefits of drinking enough water - it simply makes our body function as it should. Take a look at the range of these benefits and read more about them here.
Not all the water is the same ...
There are different categories of waters intended for human consumption such as natural mineral waters and spring waters.
Natural mineral waters may be distinguished from ordinary drinking water by their purity at source and their constant level of minerals. Spring waters are intended for human consumption in their natural state and are bottled at source.
Water that we drink comes from different sources. In many parts of the world, people drink rainwater. This is ok, as long as the water is clean and it comes from safe surfaces. Rainwater is often cleaner than groundwater or surface water.
What’s the difference between hard and soft water?
Hard water contains minerals like calcium and magnesium; soft water has [usually] been treated, and only contains sodium. Hard water is usually more pleasant to drink, while soft water is easier to wash with as it lathers with soap easier, and doesn’t leave limescale on appliances and glassware. (19)
Some people drink distilled water because it is pure, it has almost no risk of disease and it has a reduced risk of harmful chemicals. But, distilled water is safe to drink only in moderation and as a part of a balanced diet.
Infants and small children should avoid drinking distilled or demineralized water to prevent electrolyte imbalances, particularly if these are not being adequately replaced with food or other drink sources.
On the whole, drinking distilled water is not problematic when combined with other water sources. Most people eat a varied diet in developed countries and get their hydration and nutrition from a variety of sources. (21) You can read an article about how safe it is to drink distilled water.
