"Over the years, the human body becomes drier," explains the doctor. Another natural process that occurs as a person ages is acidification. "The less water we drink, the faster the body becomes both dry and acidic. The waste products of the metabolism - the acidifying substances that cause oxidative stress - should be flushed out with water. But when we don't drink enough of it, the waste builds up and pollutes the body," said Laurinavičius.
According to the doctor, you don't have to look far to find examples - if not eliminated, the body accumulates salts and bone growths, "bad" cholesterol builds up and clogs blood vessels, and you can develop stones, diabetes and other diseases.
According to the doctor, acidification of the body is the cause of many diseases and ageing, so it is very important to maintain the right balance of acids and alkalis.
Regulating the body's acidity - the balance between acids and alkalis - can be achieved through careful food choices. However, many foods are acidic, such as meat, eggs, white-flour baked goods, sweets, alcoholic and carbonated drinks, and sweetened beverages. They make the body more and more acidic.
Even a headache is a sign of water shortage
It will be difficult to maintain the body's acidity by food choices alone, but there is a simple solution - drink plenty of water, and this should be done before you feel thirsty. Experts estimate that at least 30 millilitres of water per kilogram of body mass per day is needed.
According to G.Laurinavičius, if the urine of a person who does not take medication and eats a healthy diet is dark yellow or orange, then his/her body is lacking at least a litre of water. Around the same amount of water is already missing if a person feels thirsty. Sometimes a lack of water in the body is also signalled by certain ailments, such as a headache.
According to the doctor, the Lithuanian population is lucky because the quality of borehole water in our country is very good. "The borehole water used in Lithuania comes from aquifers that date back 20,000 years and is very clean," says Mr Laurinavičius.
Lithuanians can drink even ordinary tap water, but even better is ionised alkaline water.
Scientists praise ionised water
According to Dr Laurinavičius, research by scientists in Japan, South Korea, Germany, Switzerland and the USA revealed the benefits of ionised water some time ago, and alkaline, and sometimes acidic, water often replaces expensive chemical drugs in medical institutions in these countries. In Japan, a country renowned for its long life expectancy, one in four families drink ionised water.
Scientific studies have shown that alkaline water is a natural antioxidant, just like vitamins C and E. Antioxidants, whether produced in the body or from the environment, have been shown by science to protect against many diseases. They reduce the damaging effects on the body of acidic free radicals that are produced during the metabolic process.
The example of the apple shows what free radicals and antioxidants can do. When an apple is cut open, it begins the process of oxidation. After a while, the apple turns brown. This is due to the action of free radicals. If we put a few drops of lemon juice on the apple or immerse it in ionised alkaline water, the oxidation process is stopped. Similar processes occur in the human body.
According to the doctor, a normal tap water barrel contains 11-12 molecules, while the number of molecules in the human body's water barrel is half that. This means that the body still has to restructure the tap water before it can absorb it. Alkaline water, on the other hand, has a lattice of 5-6 molecules, so the body absorbs it immediately, without having to use energy to process it.
Almost the entire human body (blood, cerebrospinal fluid, lymph, etc.) is an alkaline medium, so alkaline water (pH 7-14) is preferable. This is all the more so as alkaline water is also needed due to the body's constant acidification processes.
Another advantage of alkaline water is that it has half the surface tension coefficient of non-ionised water. Ionised alkaline water is more permeable, easier to penetrate and better able to flush the body.
According to Laurinavičius, drinking alkaline water adds oxygen to the body, which is life and energy. When there is a lack of oxygen in the body, carbohydrates are not fully broken down, and the process of fermentation takes place.
Suitable for people who play a lot of sport
Dr Laurinavičius is convinced that ionised alkaline water is beneficial for the prevention of diseases in both healthy and sick people of all ages. It is very useful for those suffering from cardiovascular diseases, heart attacks, strokes and thrombosis.
Ionised alkaline water thins the blood, makes it more fluid, prevents red blood cells from clumping together, has a positive effect on the skin, and slows down the ageing process in the body.
Studies abroad have shown that alkaline water has a positive effect on the immune system and helps treat asthma and other allergic diseases. It also helps with depression, constipation, cataracts, degenerative rheumatoid joint disease, gout, osteochondrosis of the spine, disc pathology and many other conditions.
Scientists have shown that this water also has an anti-cancer effect, as cancer only develops in acidic, low-oxygen environments. And for diabetics, drinking alkaline ionised water significantly reduces the need for insulin.
According to a doctor in Kaunas, drinking alkaline water makes it easier to lose weight. Not only because drinking more water, especially before meals, fills the stomach and prevents overeating. Drinking ionised alkaline water stimulates the sympathetic nervous system, releasing adrenaline, which activates the hormone-sensitive lipase in fat, which helps break down triglycerides into fatty acids and triglycerol. This speeds up the metabolism and burns more fat stores.
It's not for nothing that some sports clubs already have water ionisers. The lactic acid produced in the bodies of people who exercise intensively causes muscle pain, but is successfully neutralised by alkaline water.
G.Laurinavičius recommends drinking ionised alkaline water also for those who are often troubled by heartburn. "There is not too much acidity in the stomach, but too little alkalinity. If there is enough alkali in the body, over-acidity is impossible. Drinking enough alkaline water will prevent heartburn from recurring," the doctor advises.
