Low energy levels and difficulty concentrating? – DRINK UP!
There are many studies to support the fact that dehydration of as little as 1.36% can negatively affect mood, concentration, energy levels and muscular performance.
Mild dehydration affects mood in healthy young women – This study concluded that a degraded mood, increased perception of task difficulty, lower concentration, and headache symptoms resulted from 1.36% dehydration in females.
Role of dehydration in heat stress-induced variations in mental performance – The results of this study indicated significant deterioration in mental functions at 2% or more body dehydration levels.
Does Fluid Balance Affect Strength, Power and High-Intensity Endurance? – This critical review of the available literature suggests hypohydration limits strength, power and high-intensity endurance and, therefore, is an important factor to consider when attempting to maximise muscular performance.
How much water should I be drinking each day? The proof is in the pee.
On average most adults require 1.5-2L of water per day, but this depends on your physical activity, work environment and air-conditioning, how much coffee or tea you drink – as these can all contribute to dehydration. You will be on the right track if your urine is clear or pale. If it’s darker, keep on drinking!
