Q. What happens if you drink less water?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Drinking an insufficient amount of water can lead to a range of negative effects on your body and overall health. Here are some potential consequences of not drinking enough water:
Dehydration: The most immediate consequence of not drinking enough water is dehydration. Dehydration occurs when your body loses more fluids than it takes in. Mild dehydration can lead to symptoms like dry mouth, increased thirst, darker urine, and fatigue. Severe dehydration can be dangerous and may require medical attention.
Impaired Physical Performance: Lack of adequate hydration can lead to reduced physical performance, as your body relies on water for energy production, muscle function, and circulation. Exercise tolerance and endurance may decrease if you're dehydrated.
Cognitive Function: Dehydration can affect cognitive function, leading to difficulty concentrating, decreased alertness, and impaired memory. Even mild dehydration has been shown to impact cognitive performance.
Kidney Function: Adequate water intake is important for proper kidney function. Insufficient water can lead to concentrated urine, which might contribute to the formation of kidney stones. Chronic dehydration may also increase the risk of kidney problems over time.
Digestive Issues: Water plays a crucial role in digestion and the movement of food through the gastrointestinal tract. Insufficient water intake can lead to constipation and other digestive problems.
Skin Health: Hydration is essential for maintaining healthy skin. Without enough water, your skin can become dry, flaky, and more prone to issues like acne and irritation.
Temperature Regulation: Water helps regulate body temperature through processes like sweating. Inadequate hydration can make it harder for your body to cool itself down, potentially leading to heat-related illnesses in hot weather.
Mood and Energy Levels: Dehydration can impact mood and energy levels, leading to feelings of irritability, low energy, and even mood swings.
Urinary Tract Health: Drinking enough water helps flush out bacteria and toxins from the urinary tract, reducing the risk of urinary tract infections.
Cardiovascular Health: Proper hydration is important for maintaining healthy blood pressure and circulation. Dehydration can strain the cardiovascular system and increase the risk of issues like dizziness and fainting.
