Hydro Hunger

Water is essential to our survival, and staying hydrated is crucial for maintaining good health. However, many people don't drink enough water each day, which can lead to dehydration and a range of health problems. In this blog post, we will discuss how much water we need to drink, why water is so important, and what dehydration can do to the body.

How much water do we need to drink?

The amount of water we need to drink each day depends on several factors, such as age, gender, activity level, and climate. However, the general rule of thumb is to drink at least eight glasses of water per day, which is equivalent to about 2 liters. This amount may need to be increased for individuals who are more physically active or who live in hot climates.

Why is water so important?

Water plays several essential roles in the body. It helps to regulate body temperature, lubricate joints, transport nutrients and oxygen to cells, and remove waste products from the body. Water also helps to keep our skin healthy and glowing, and it can help to promote weight loss by reducing appetite and increasing metabolism.

What happens to the body when we are dehydrated?

When we don't drink enough water, the body becomes dehydrated. Mild dehydration can cause symptoms such as dry mouth, headache, fatigue, and dizziness. Severe dehydration can be life-threatening and requires immediate medical attention.

Dehydration can have a range of negative effects on the body, including:

  1. Impaired cognitive function: Studies have found that dehydration can impair cognitive function, including memory and attention.

  2. Increased risk of kidney stones: Dehydration can lead to the formation of kidney stones, which can be painful and may require medical intervention.

  3. Digestive problems: Dehydration can cause constipation and other digestive problems.

  4. Increased risk of heat-related illness: Dehydration can increase the risk of heat exhaustion and heat stroke, especially in hot and humid environments.

The Science

Several studies have investigated the effects of dehydration on the body. One study found that even mild dehydration can impair cognitive function and mood in young adults. Another study found that dehydration can lead to an increased risk of kidney stones. A review of studies found that dehydration can impair physical and cognitive performance and increase the risk of heat-related illness.


Water is essential to our health, and staying hydrated is crucial for maintaining good health. Drinking at least eight glasses of water per day can help to keep us hydrated and promote optimal bodily functions. Dehydration can have a range of negative effects on the body, including impaired cognitive function, digestive problems, and an increased risk of heat-related illness. By drinking enough water each day, we can help to keep our bodies healthy and functioning optimally.
