The human adult body is composed of up to 60% water, making this life-giving liquid more than just a means to quench your thirst. The numerous health benefits of staying hydrated range from lubricated and cushioned joints to improved detoxification, so drinking enough water each day is essential for healthy bodily function. This article will delve more deeply into this topic and explore some benefits of staying hydrated.

Recommended daily intake

How much water should you drink can vary based on several factors such as age, gender, physical activity level, and climate.  In general, however,  it is recommended to drink eight glasses, or two litres, of water per day.  It is also advisable to pay attention to your body and drink water when you feel thirsty. 

The color of your urine can also indicate your levels of hydration and the need to drink more or less water. Urine that is a light yellow or honey color suggests your body is healthy and hydrated whereas a darker yellow or amber colour can alert you to the need to consume more water. Below are some of the main benefits of drinking enough water each day:

Enhanced brain function

Since 75% of the brain mass is made up of water, even a slight decrease in hydration can have a noticeable effect on your mental health. According to a study published in the Journal of the American College of Nutrition, mild hydration of just 2% can impair your brain function resulting in symptoms such as memory loss, poor focus and attention, slow processing of information, irritability, and headaches. Staying hydrated can help to increase oxygen and blood flow to the brain which can enhance cognitive function and mental well-being.

Aids detoxification

Staying hydrated is essential to support your body’s natural detoxification processes as it helps to flush out waste products from the body through sweat and urine and keeping the liver and kidneys hydrated enables these organs to function effectively to remove waste from the body. 

Drinking enough water also aids the body in dissolving toxins, facilitating their removal, and promoting regular bowel movements, which are crucial for eliminating waste from the body.

Better joint health

Water plays a vital role when it comes to joint health. An essential ingredient of synovial fluid, water helps to lubricate and cushion the joints, resulting in less friction between the bones. Staying hydrated also keeps the cartilage around the joints soft and smooth, increasing its ability to absorb shock and reduce wear and tear on the joints. Adequate hydration can prevent degeneration of the joints and ward off conditions such as inflammation, gout attacks, and rheumatoid arthritis.

Increased energy levels

Dehydration can have a negative impact on blood circulation and oxygen flow to the brain, leading to feelings of fatigue, sluggishness, and decreased focus. This depletion of energy occurs when the body is not adequately hydrated, causing the heart to work harder to pump enough oxygen throughout the body.  Staying hydrated can help you to improve circulation and maintain your energy levels throughout the day.

Make sure you are drinking enough water each day to help your body and mind function at their optimum.
