According to the Holmes and Rahe Stress Scale, different life events have varying levels of stress severity. The events are arranged from highest to lowest severity as follows: - Death of a close family member: Ranked as one of the most stressful events. - Unexpected accident or trauma: Accidents or traumas are also highly stressful but rank below death of a family member. - Illness of a family member: Illness, while stressful, ranks lower than trauma or death. - Break-up with friend: Emotional relationships can cause stress, but less than death or serious illness. - Change in eating habits: Lifestyle changes like eating habits are relatively minor stressors.
