Executive Summary

Inflammatory skin conditions can significantly increase the amount of water lost through the skin. Ensuring your meet your daily requirements can help restore adequate hydration and improve immune system stability.


Water is essential to our health and serves a large variety of roles in the human body. For example, our bodies utilize water as a building material, a carrier for nutrients, in waste management, in thermo-regulation, as a lubricant and many other diverse functions.

Because of it’s importance, our bodies typically keep it’s balance very precise and a loss of 1% is usually compensated within 24 hours [1]. And dehydration of as little as 2% of body weight can result in impaired physiological and performance responses.

Luckily water consumption has been growing in popularity and the two of the most popular recommendations for daily consumption are:

  • Eight 8oz (240mL) glasses [2]
  • 1.5L in total [3]

However, these recommendations are based on average conditions and specific requirements actually depend on various individual factors, including:

  • Climate
  • Physical activity
  • Diet (amount of water provided by food)
  • Skin barrier stability

In any case, to put things into perspective it helps to understand how much water an average adult looses per day and where it goes.

On average, a sedentary adult losses 2.55L of water per day, via the following routes:

  • Urine – 1.6L (62.7%)
  • Skin – 0.45L (17.6%) (inflammatory skin conditions can increase amount of water lost) [4, 5]
  • Respiratory system – 0.3L (11.8%)
  • Feces – 0.2L (7.8%)

Documented Benefits:

Water is a crucial component of every single cell of our bodies and even fills the space between them. This alone should be indicative of it’s importance. But having a look at some specifics can help put this into perspective [6]:

  • Helps moisturizer the skin from inside
  • Required for healthy immune function
  • Assists kidney and liver function
  • Digestion, absorption, transpiration and use of nutrients and minerals

Why It’s Important for Inflammatory Skin Disease

Characteristics most important for individuals affected by inflammatory skin disorders:

  • Increased skin hydration [7]
  • Improved immune system stability
  • Improved nutrient nutrient absorption

Expected improvements:

  • Improved skin stability and skin cell integrity
  • Reduced hypersensitivity

Ideas for Easier Integration:

Here are some times you can use to drink a glass of water:

  • First thing in the morning
    keeping a bottle of water next to the bed will serve a simple reminder
  • Prior to eating lunch
  • Whenever feeling of hunger emerges
  • Before dinner

And bringing a bottle of water to work, school or wherever most of the days is spent can help ensure your always hydrated.

Additional Notes:

  • There appears to be some difference between the effect of tap water and mineral water on skin structure [8] – obtaining a mix of different types of water (tap, boiled, mineral) should be considered
  • US adults (consuming on average 2.2L per day) appear to be well hydrated compared to Europeans (less then 0.5L) [9]
