The intake of electrolytes can be useful for people of all ages in certain situations. Older people in particular do not necessarily feel dehydrated. In the following cases, taking electrolytes can also be helpful.(11)
Sport
During sport, the body loses a lot of fluid. So in addition to the 1.5 litres of fluid recommended as a daily guideline, more water should be added to the body. But it also excretes minerals. Sodium is particularly affected.
If too much water is drunk during heavy exercise, the lack of sodium can lead to a dilution of the blood. Neurological consequences are not uncommon.
