Put emotional or physical effects together and you will end up eventually with mental effects. The mental effects are part and parcel with the other effects and will ultimately lead to behavioural effects.
So as we have seen the stress does manifest in many ways and can hit you at any time. Here are a list of the mental symptoms and effects.
Poor decision making
More ego centred, less group centred
Poor memory and recall
Inability to asses work and decisions
Short burst of energy instead of a steady effort
Loss of mental agility
Poor time management
Inability to listen
Wavering attention span.
With the above we all suffer now and again, mainly due to things like, quick changeover, lack of sleep, and worry about something or anything that may crop up. It is a vicious circle that needs resolving. How we deal with them will decide how it affects us. Normally sleep, a couple of days off or resolution of the problem stops the circle that eventually leads to burnout.
