More than half of the human body is made up of water. This fluid is indispensable in helping different organs carry out their functions correctly. Drinking less water can cause dehydration and contribute to several health conditions. To avoid complications, smartwatches and mobile apps have been developed to remind people to drink water regularly and stay hydrated. The following are a few common repercussions one may face due to less water intake. Constipation Water helps food move through the gastrointestinal tract. When the body does not have sufficient water, it cannot perform this function effectively. As a result, individuals may experience hard stools or constipation. Bad breath Water helps produce saliva and destroy the bacteria inside the mouth, resulting in optimal oral hygiene. Dehydration hampers this process, leading to bad breath. The foul smell may not recede despite brushing regularly and practicing other oral care activities. Skin problems Although moisturizing and cleansing are essential skincare practices, they are typically ineffective if one does not drink enough water. Dry skin is among the most common symptoms of dehydration. The skin may appear sunken and dull, with dark circles underneath the eyes and chapped lips. Dark-yellow urine When a person is dehydrated, the kidneys try to conserve water in the body, which causes the urine to become darker in color.
