Dehydration can cause many symptoms in people that are unexpected and undiagnosed, adding the correct amount of water and salt to a diet is a great starting point to ensure optimum health. First start by checking how much water you are drinking, and make sure it is a good source of clean and filtered water. You should steer clear of processed and common white refined table salts, these really are toxic to your system, and can threaten to increase blood pressure in patients. However a good unrefined source of salt such as himalayan salt can actually normalise blood pressure, as it contains a blend of 84 different naturally occurring minerals that the body actually needs. A good starting place is to aim for 2 litres of water per day and add about 1/2 tsp of unrefined salt to that.
