Mental Exhaustion (Fatigue): Symptoms, Causes, and Recovery Tips Mental exhaustion is a common occurrence and is a result of brain over-activity. Feelings of being overwhelmed by tasks at work or responsibilities to children and family members can leave you with feelings of frustration and mental unrest. You may also find yourself becoming envious of others you perceive as being more relaxed or laid back, as your level of mental stress can make you detest those who seem to have it easier.

When you spend a lot of mental effort on a task, you become mentally exhausted. Though manageable at first, over time, your ability to maintain your focus becomes hampered. This may leave you with an inability to concentrate, performing more mistakes than normal. Feelings of being stressed, irritated, and even depressed can lead you into a downward spiral, potentially affecting your health and the people around you.

What are the signs and symptoms of mental exhaustion?

Mental exhaustion can be easily recognized as feelings of being “burnt out” from excess, long-term stress—it is something we have all experienced before. Symptoms may initially present subtly, but over time, they become worse. It is important to note that mental exhaustion may eventually manifest as physical, emotional, and behavioral symptoms, as all these attributes are connected to the organ receiving the blunt of the mental stressors: the brain.

Physical symptoms: This may include feelings of being tired most of the time, an increased tendency for becoming sick, frequent headaches, back pain, or muscle aches. You may also notice changes in appetite and sleep habits.
Emotional symptoms: This can manifest as feelings of helplessness, as you feel trapped and defeated by your overwhelming sense of mental stress. The sense of self-doubt and failure may encompass the majority of your thoughts throughout the day, leading you to isolate yourself and develop a pessimistic view of the world and life in general.
Behavioral symptoms: You may notice yourself not spending as much time with your friends and family because you feel too tired to make the effort. Procrastination and withdrawing from previous responsibilities can also be a sign of mental exhaustion. Your eating habits may change as well, whether it’s eating more or eating less. The use of alcohol or drugs to help cope with increased levels of stress may also be a predictor of increased mental stress levels.

What causes mental exhaustion?

Mental exhaustion does not necessarily occur in one fell swoop, but instead, it slowly accumulates over time. Being overworked, having too many responsibilities, or simply having too much going on in your life can cause you to reach an eventual boiling point, where your mind and body cannot cope anymore. This is when symptoms start to manifest.

When our capacity for dealing with stress becomes depleted, it may knock us back into a state of perpetual mental fatigue. This can even lead to potentially serious health issues such as depression, heart disease, chronic illness, and autoimmune disorders.

Mental exhaustion complications

Mental exhaustion can take a toll on virtually every aspect of a person’s life. Poor work performance due to decreased productivity can lead to negative consequences at your job, such as demotion or termination. Your irritability and poor mood could affect the people around you, leading to conflict with friends and loved ones. Your level of mental exhaustion may also affect how you perform during physical tasks, as the brain may perceive simple tasks as being arduous and tiring due to your lack of motivation.

How to recover from mental exhaustion?

The mind and body are quite resilient and are capable of making a full recovery from the most harmful of physical injuries, and this holds true for mental exhaustion as well. The biggest challenge is to admit a change needs to be made in order to recharge mentally and not feel guilty about it. The following are some simple tips that don’t require much energy but will set you on a path toward mental rejuvenation.

Find the time to relax: One of the biggest reasons for stress accumulation is the lack of time allocation to relieve it. If you have no outlet to relieve stress, it will continually build up and start to manifest into stress-related symptoms. Finding a spare minute here and there to collect your thoughts without distraction can help ease your mind. Spending some time to destress after work in a quiet location can help balance your stress level throughout the rest of the day.
Reduce sensory stimulation: Being around excess noise and light can bombard the senses, leading to stress. Your body is most relaxed when sitting in a dimly lit, quiet room with minimal distraction. Constant sensory stimulation from electronic devices, such as a television or smartphone, can cause eye fatigue, leading to headaches and even insomnia. If at all possible, visiting a local park for the weekend can help give you a sensory reset.
Prioritize: Not all things are worth doing, and some of the unimportant aspects of your life may be the biggest contributors to your stress. Recognizing the things that you hold near and dear to you and letting go of the unnecessary baggage that may be mental exhaustion causes can be a cathartic experience and a great method for mental exhaustion recovery.
