Health Benefits of Water

As you may already know, water is essential for our body to carry out its functions. However, drinking sufficient amount of water also has numerous health benefits such as:

  • Impacts Brain Function

Research has shown that the status of your water intake affects your brain. The functions of your brain are impacted even by mild levels of dehydration. A study by NCBI reported that 1.4% of fluid loss affected the concentration and mood in the female participants. A similar study was conducted on male participants with 1.6% of fluid loss resulting in increased levels of fatigue and anxiety.

  • Enhances Physical Performance

During high heat or intense workout sessions, dehydration can affect physical performance quite negatively. Losing as much as 2% of the body’s water content can lead to increased fatigue, lower levels of motivation, changes in the control of body temperature, etc. But staying hydrated helps avoid such effects on your body.

  • Helps With Constipation

Facing difficulties in passing stools or experiencing infrequent bowel movements can result in constipation. However, increasing your water intake can help with relieving constipation along with other benefits. Studies have reported that low water intake is one of the issues for constipation in older and younger people. Consuming water rich in sodium and magnesium can help with constipation.

  • Treats Headaches

A lower intake of water can lead to headaches and sometimes migraines. Some research studies have shown that hydration causes headaches and consuming enough water can relieve pain in people who have regular headaches.

  • May Treat Kidney Stones

You must have heard about kidney stones and how they can be painful. There aren’t many studies available to back up the benefits of drinking water for kidney stones. However, increased fluid intake can result in higher volumes of urine that passes through the urinary system, which might help with kidney stones.
