The following is a list of the major symptoms of stress that you might feel:
Physical Symptoms - mainly in response to increased levels of adrenaline:
Increase in heart rate
Increase in Sweating, and a cooler skin as this combines with a reduction in the blood flow to your skin.
'Butterflies' in your stomach
A desire to urinate
Confusion, inability to concentrate or difficulty making decisions
Feeling ill or odd
Feeling out of control or overwhelmed
Nervous mannerisms: nail biting, foot tapping, increased blinking, twitching, pacing
These symptoms of stress should not be taken in isolation - they could be caused by other factors. However if you find yourself exhibiting or recognising a number of them, then it would be worth investigating stress management techniques.
