Warning signs of brain instability

The brain has many ways to warn the body that something is wrong, such as difficulty sleeping, being emotional, changes in appetite, and fatigue.

The human brain reacts to stress in different ways. Here are signs that something is wrong with it.

Difficulty sleeping

Poor sleep can be a sign of depression or anxiety, which manifests as sleeping too little or too much. Frequent oversleeping can also be caused by being tired to the point of exhaustion. Some people stay up all night thinking, which puts their brains into overdrive.

A 2022 study from Brigham Young University in the US found that high levels of the stress hormone cortisol are linked to reduced sleep time.

Bored

People who are chronically stressed often lose interest in things that once brought them joy.

According to a 2020 study by the University of Melbourne, Australia, and Umea University, Sweden, burnout disorder is a stress-related condition that causes feelings of emotional and physical fatigue. This leaves sufferers without the energy to engage in normal activities.

Emotional

Feeling irritable, feeling easily frustrated or having mood swings are common signs of chronic stress or a mental breakdown. According to scientists , stress causes the brain to continuously produce the hormone cortisol. High levels of cortisol can increase feelings of anger and irritability.

Change of taste

A 2019 study by Ohio State University, USA, showed that stress affects health through its impact on gut bacteria, causing patients to lose their appetite or experience digestive discomfort such as constipation and diarrhea.

On the contrary, some people who are too stressed or have nervous breakdowns can increase the hormone cortisol, causing cravings for fatty, sugary foods. This conclusion was published by scientists at Yale University, USA, in 2019.

Poor health

Depression and anxiety can cause physical side effects, including sweating, rapid heartbeat, dizziness, gastrointestinal symptoms, and headaches. If these symptoms appear suddenly without any other underlying cause, it may indicate a decline in mental health.
