Stress helps us to cope with challenging situations in the short term. The body, when stressed is prepared to fight, flight or freeze and is on high alert. However, if the body is constantly stressed, this is where stress can have a major impact on the body. So, blood pressure, heart rate and breathing will increase, putting pressure on the heart and other internal organs. Moods can change and irritability and depression can occur. Eating habits can change, causing weight loss or gain (obesity and diabetes), possibly leading to anxiety. This will also cause poor digestion, headaches and even alcohol and drug abuse.
