  • High Levels of Stress: Long-time stress tends to create a state of hypervigilance, and it becomes hard to calm down.

Aggression is a typical behavior exhibited by persons with anxiety due to the much stress that the body is under. Those who suffer from anxiety may notice that they are more easily troubled or angered by a circumstance they would otherwise ignore.


  • Hyperarousal State of the Nervous System: Facing stress constantly puts the body into the fight or flight mode and this becomes ineffective, frustrating the body.
  • Hormonal Fluctuations: These hormonal changes are affiliated with a change in mood and an increase in temper and irritability.

Anger may lead to worsened relationships and makes the execution of social tasks more difficult. This symptom can be helpful in the elaboration of some strategies to avoid reaching the point of getting angry and frustrated.

Anxiety Symptom 6: Muscle Tension

Muscle tension is another somatic manifestation of anxiety that most individuals write about. It is the experience of having muscles become tight or stiff, and it usually happens without implementing any effort.

  • Body’s Fight-or-Flight Response: This is due to the body’s ability to produce sweat whenever it is under pressure and therefore the muscles constrict.
  • Lack of Relaxation Techniques: Failure to use relaxation techniques results in contracted muscles which may be tightened for long term.

Stress in muscles can cause distress and ache limiting individuals from performing routine activities. Tensing and relaxing muscles through deep breathing exercises, progressive muscle relaxation, and through a daily exercise regimen may assist with muscle tension.

Anxiety Symptom 7: Sleep Disturbances

Inability to sleep or wake up frequently at night is one of the most common complaints found in anxiety patients. These disturbances involve having a hard time sleeping, staying asleep, or sleeping soundly. This, in turn, leads to the worsening of anxiety symptoms due to poor sleep quality, hence making it a cycle.


  • Hyperarousal and Racing Thoughts: Anxiety may cause the mind to stay working and awake because the mind doesn’t get to rest and relax enough to sleep.
  • Disrupted Sleep-Wake Cycles: Stress including anxiety is known to disrupt the sleeping pattern and hence it becomes difficult to have a natural sleep cycle.

Lack of sleep results in such effects as tiredness during the day, poor concentration and irritability. Simple practices that range from setting up sleep schedules, avoiding the use of electronic gadgets before bed, and the use of relaxation methods can effectively reduce anxiety hence promote quality sleep.
