Nervous behavior can manifest in various ways, and it often depends on the individual and the specific situation. Here are some common examples of nervous behavior:

1. Fidgeting: People may fidget by tapping their fingers, bouncing their legs, or playing with objects like pens or jewelry when they’re feeling nervous or anxious.
2. Nail Biting: Some individuals have a habit of biting their nails when they’re nervous or stressed.
3. Avoiding Eye Contact: Avoiding eye contact is a common sign of nervousness, as some people find it difficult to maintain eye contact when they’re anxious.
4. Nervous Laughter: People may laugh or giggle inappropriately or excessively when they’re nervous, as a way to cope with their anxiety.
5. Stuttering or Stammering: Difficulty speaking smoothly, including stuttering or stammering, can occur when someone is feeling nervous or under pressure.
6. Sweating: Nervousness can lead to increased sweating, particularly on the palms, forehead, or underarms.
7. Shaking or Trembling: Shaky hands or trembling can be a physical manifestation of nervousness.
8. Nausea or Upset Stomach: Some individuals may experience stomach discomfort, nausea, or even gastrointestinal issues when they’re anxious.
9. Rapid Breathing or Hyperventilation: Nervousness can cause increased breathing rate or hyperventilation, which can lead to dizziness or lightheadedness.
10. Freezing or Stiffening Up: In some situations, people may become rigid and have difficulty moving when they’re nervous.
11. Excessive Talking: Some people may talk more than usual when they’re nervous, perhaps as a way to fill the silence or distract themselves from their anxiety.
12. Looking for Distractions: Nervous individuals may constantly look for distractions, such as checking their phone or repeatedly glancing at their watch.
13. Overthinking or Obsessing: Nervousness can lead to obsessive thoughts or overthinking a situation, which can be mentally exhausting.
14. Seeking Reassurance: Nervous people might seek reassurance from others frequently, asking questions like, “Am I doing okay?” or “Is everything alright?”
15. Avoidance: Sometimes, nervousness can lead to avoiding certain situations or people altogether to prevent having to confront their anxiety.

It’s important to note that these behaviors can vary in intensity and may not always be indicative of nervousness; they can also be coping mechanisms for dealing with stress or social situations. If you or someone you know frequently exhibits these behaviors and it’s interfering with daily life or causing distress, it may be helpful to seek support from a mental health professional.
