Nervous tension is a feeling familiar to many people. It can occur in various situations, for example before an important presentation, an exam, as a result of time pressure or in unusual as well as unfamiliar social interactions.

Symptoms vary from person to person. Some people experience nervous tension, others become irritable or suffer from listlessness and sleep disorders. Cramp-like stomach and intestinal complaints may also become noticeable.

Mental tension or states of tension describe a condition of increased emotional, mental and even physical tension. They can be triggered by various factors such as stress, worries, fears or high expectations. In these circumstances, physical symptoms such as tension or sleep disorders often become evident. They can also lead to an impairment of concentration, mood and general well-being.

The symptoms of restlessness are usually similar to those of nervousness and tension. They are often accompanied by physical symptoms such as trembling, increased heart rate, sweating or gastrointestinal complaints. At the same time, there may be recurring thoughts, concentration may be impaired and feelings of inner compulsion or restlessness may occur. Causes of mental restlessness are usually stress, anxiety, worry or certain mental illnesses.

Exam nerves are a common form of fear that occurs before or during exams. The condition manifests itself in physical symptoms such as nervousness, palpitations, sweating or gastrointestinal complaints. Exam nerves can detract from concentration and performance.
