what is stress?
Stress is often described as a feeling of being overloaded, woundup tight, tense and worried. We all experience stress at times. It can
sometimes help to motivate us to get a task finished, or perform
well. But stress can also be harmful if we become over-stressed
and it interferes with our ability to get on with our normal life for
what are the signs of stress?
When we face a stressful event, our bodies respond by activating
the nervous system and releasing hormones such as adrenalin and
cortisol. These hormones cause physical changes in the body which
help us to react quickly and effectively to get through the stressful
situation. This is sometimes called the ‘fight or flight’ response.
The hormones increase our heart rate, breathing, blood pressure,
metabolism and muscle tension. Our pupils dilate and our
perspiration rate increases.
While these physical changes help us try to meet the challenges
of the stressful situation, they can cause other physical or
psychological symptoms if the stress is ongoing and the physical
changes don’t settle down.
These symptoms can include:
• Headaches, other aches and pains
• Sleep disturbance, insomnia
• Upset stomach, indigestion, diarrhoea
• Anger, irritability
• Feeling overwhelmed and out of control
• Feeling moody, tearful
• Difficulty concentrating
• Low self-esteem, lack of confidence
• High blood pressure
• Weakened immune system
• Heart disease
