As soon as winter arrives, our water bottles remain full. In cold weather, we feel less thirsty and we often forget to drink water. If you also have this habit, then you need to be careful. This small carelessness can make your body hollow from inside and become home to many serious diseases. Health experts believe that if a person drinks less than 500 ml of water (i.e. only 2-3 glasses) daily for a long time, then it can prove to be dangerous for him. Let us know what fatal effects drinking less water can have on your body. 1. Your kidneys may fail. This is the biggest and most direct danger. When you drink less water, your kidneys have to work harder to clear toxins from the body. What happens? Due to less water, your urine becomes concentrated. Due to less release of water from the body, dirt starts accumulating inside, which directly puts pressure on your kidney and starts damaging it. 2. Oxygen does not reach the brain, memory decreases. Water is a major part of our blood. Drinking less water reduces the blood volume in the body, which has a direct impact on your brain. What happens? Due to lack of blood, the supply of oxygen reaching the brain decreases. Due to this, you start having problems like difficulty in concentrating, forgetfulness, unnecessary fatigue, irritability and mood swings. 3. Tiredness and muscle pain all the time: Do you also feel lazy and body ache all the time in winter? A major reason for this can be drinking less water. What happens? Water is very important for creating energy in the body. Due to its deficiency, your energy level falls and the problem of muscle pain (muscle soreness) increases. 4. Digestive system gets jammed, gas gets formed in the stomach and constipation. Water plays a big role in the entire process of digesting our food. If there is lack of water in the body, the digestive system does not function properly. What happens? Due to lack of water, your digestion slows down, due to which food is not digested properly. As a result, you start having problems like constipation, indigestion and gas, and your appetite is also affected. 5. Stress and tension increases: You will be surprised to know, but drinking less water can also increase your stress level. When there is a lack of water inside the body, it is unable to function properly, which creates a kind of physical stress. What happens? Lack of water also reduces the body’s ability to control temperature, due to which you can become a victim of many other diseases. Therefore, no matter what the season is, do not let there be a lack of water in your body. Keep drinking water at regular intervals even if you do not feel thirsty, so that you can stay away from these serious diseases.
