What are the main causes of stress?
Stress can have different meanings for different people. Stress can be a real or perceived threat to one’s condition. Stress can come from physical elements, such as excess heat or cold, trauma, physical exertion, and hunger or thirst. Psychological or social stressors could come from feelings of fear, anger, frustration, or bereavement. Some of the most commonly cited sources of stress are related to work, family and financial worries. Positive events may also be sources of stress such as a new job or promotion, purchase of a home, marriage, or birth of a child.
What effect does stress have on the body?
Stress is a normal physiological response. If we are exposed to stress for a short duration, normal physiological responses may include increased heart rate, decreased appetite, and greater alertness, which helps to deal with stress over the short term. The negative effects of stress typically come from chronic, long durations of exposure to stress or experience with severe stressful events, such as natural disasters or violence. In these situations, stress may lead to more serious health conditions, such as depression, heart disease, weight gain or loss, gastrointestinal problems and diabetes.
How can I effectively manage stress in my life?
Stress levels differ based on each individual's personality and how he or she respond to situations. Some people are able to deal with stress and let it go. To them, work and life stresses are just little bumps in the road. Others may dwell on stressful environments or events and literally worry themselves sick. For these people, effective coping strategies are very important. Getting regular exercise, eating a healthy diet, having social support and participating in stress management programs are some effective ways of managing stress
