Stress is our body’s natural reaction to a demand or threat. It triggers your body’s fight, freeze or flight response, which causes a surge of hormones that would have helped our ancestors to run away from the stressor or fight it. It is supposed to be a short, sharp response to danger. But if you feel stressed a lot of the time, you put a lot of pressure on your health.
Stress can come from many sources such as health issues, relationship problems, work, financial issues, deadlines, exams or unrealistic expectations you put on yourself. What causes stress for you may not be stressful for someone else.
Some stress is helpful as it can motivate you to meet a deadline or get things done. But long-term stress can increase the risk of health conditions, such as:
- high blood pressure
- obesity and diabetes
- depression or anxiety
- heart disease
- muscle tension, headaches
- irritable bowel syndrome (IBS)
- suicide in extreme situations.
A stress-related condition called post-traumatic stress disorder (PTSD) can develop after experiencing trauma, such as from war, physical or sexual assault, or a natural disaster.
