PH value of alkaline water & gt7 water. Generally speaking, the PH value of water will show obvious differences according to different regions. For example, in cities north of the Yellow River, drinking water is weakly alkaline. Some people who believe in the efficacy of alkaline water believe that eating acidic food will lead to osteoporosis, listlessness, obesity and even increase the risk of cancer, but drinking alkaline water can effectively remove these acidic substances, thus playing a neutralizing role.

There are also some merchants who implicitly suggest that alkaline water can kill cancer cells when promoting their products. They even labeled alkaline water as "quickly replenishing body water, improving body function, losing weight, strengthening bones, improving skin and resisting allergy". But these are all nonsense, and there is no research data to support the conclusion that ordinary water can even take acidic substances out of the body.

Since alkaline water is not good for human body, why can it be so sought after? In addition to the false propaganda of merchants, there are also people's psychological hints. After drinking alkaline water, some people's symptoms such as fatigue, headache, dizziness and constipation have been effectively alleviated. But this is only a symptom of dehydration, and any water can play the same role.

In fact, we don't need to pursue alkaline water. Even if we want to stay healthy, we just need to drink enough water every day. According to the research data, we suggest that men need to drink about 3. 12 liters of water every day, women need to drink about 2. 16 liters of water every day, pregnant women need to drink about 2.4 liters of water every day, and lactating women need to drink about 2.88 liters of water every day.

For people who stay outdoors in hot weather or sweat heavily for a long time, they need to drink plenty of water to keep hydrated, and people with symptoms such as vomiting, diarrhea or fever also need to drink plenty of water. But for patients with heart failure or some type of kidney disease, they may need to limit their water intake.
