What are the effects of anxiety on the body?

Anxiety can have a number of effects on the body, both immediately and over time. The following are some common physical symptoms of anxiety:

• Palpitations and rapid heartbeat
• Sweating
• Shaking or trembling
• Shortness of breath or the sensation of choking
• Nausea or stomach upset
• Feeling dizzy or lightheaded
• Tension in the muscles and headaches
• Insomnia or sleeping difficulties
  
• Tiredness and exhaustion

These symptoms are frequently the result of the body's "fight or flight" response, which is triggered by stress or anxiety. This response causes the release of adrenaline and other stress hormones, which can result in the above-mentioned physical symptoms.
