Mental fatigue can be defined as a sensation of tiredness accompanied by deterioration in performance caused by prolonged periods of cognitive activity. Since the late 1800s, many researchers have analysed the effects of prolonged cognitive activity, involving memory, judgement, reasoning and other mental abilities. There are dozens of studies which prove mental fatigue can cause a fall in our work-related memory (that deals with the management and organisation of information) and a general deterioration in individuals’ mental ability.
Mental fatigue is also defined as “mental burnout” or “mental fog” and is a problem for all those, young people and adults, workers and students, whose jobs are mainly based on cognitive functioning. When we are overloaded with cognitive tasks to complete in a limited timeframe, mental fatigue and its effects set in.

To fight mental fatigue it’s necessary to eliminate the root causes – reducing or completely eliminating the source of excess loads on our brain. It’s also important to try to follow a healthy lifestyle that takes account of nutrition, rest and physical exercise (preferably outdoors). More often than not, completely removing the source of excess pressure isn’t always possible but we can attempt to reduce this by using products that help us in overcoming moments of difficulty.
