changes, for others it can turn into long-term exhaustion and fatigue.

SYMPTOMS OF MENTAL FATIGUE
Anxiety
• Feeling fatigued mentally can create stress. Stress about whatever the issue is that has 
caused the mental fatigue in the first place, or about other aspects of our lives. 
• This stress, or anxiety, may cause feelings of worry, fear, nervousness, and many other 
emotions that create uncertainty.

Memory
• Our memories, whether short-term or long-term memories are saved in our memory 
bank when we are rested and feeling sharp. This becomes a problem when we are 
suffering from mental fatigue.

Emotional Sensitivity
• Our emotions are sacred to us. They are an important part of who we are and how we 
present ourselves. 
• When we are under mental stress and exhaustion, our ability to process our emotions 
and how we react to specific situations may be altered.

Changes in Appetite
• The way in which we eat can be affected by our mood and our mind. Some people may 
deal with mental fatigue by stress-eating. Stress eating is when a person makes poor 
food choices, specifically binging on large portions of unhealthy junk food or fast food.
