I have outlined the causes and effects of stress in this article. I hope you find it useful. Stress itself is not necessarily harmful. Learning how to deal with stress is important to both your—physical and your mental well-being. What stresses one person may not stress another.


What is Stress

Stress is a natural response that enables you to deal with challenging or dangerous situations. Any intrinsic or extrinsic stimulus that evokes a biological response is known as stress. Your brain causes hormones to flood your system. These increase your heart rate, regulate your blood pressure, expand or constrict the capacity of your lungs, and tense your muscles. Before you are fully aware of what is happening, your body is prepared for action. 

The body reacts to these changes with physical, mental, and emotional responses. Stress is a normal part of life. You can experience stress from your environment, your body, and even your thoughts. The causes and effects of stress can vary from one person to person. 


5 common causes of stress on Your Body


1. Insecurity—financial, job or otherwise

While most of us feel insecure sometimes, some of us feel insecure most of the time. This can come as a result of different factors. Financial problems, search for a good job, the kind of childhood you had, past traumas, recent experiences of failure or rejection, loneliness, social anxiety, negative beliefs about yourself, perfectionism, or having a critical parent or partner can all contribute to insecurity.—which can subsequently lead to stress.

2. A demanding routine

Demanding routine can take a huge toll on everyone. Demands can come from work, relationships, financial pressures, and other situations. These demanding routines can pose a real, or perceived challenge or threat to a person’s wellbeing—which in turn, can cause stress but anything that poses a real or perceived challenge, or threat to a person’s well-being can cause stress.

Also, when there are too many stressors at one time, it can undermine a person’s mental and physical health and become harmful.

3. Interpersonal conflicts

Interpersonal conflicts happen as a result of quarrels, arguments, an uncomfortable atmosphere during a conversation, or activity, negative attitudes or behavior between two or more persons. Furthermore, the most studied organizational stressors are interpersonal conflicts with supervisors and/or coworkers, lack of control, work overload, role conflict, role ambiguity, lack of autonomy, lack of support, job insecurity, long work hours, and situational constraints.

4. A traumatic experience

When you experience a traumatic event, your body’s defences take effect, and create a stress response, which may make you feel a variety of physical symptoms, behave differently and experience more intense emotions. A study by psychologists has found that traumatic life events are the biggest cause of anxiety and depression, but how a person thinks about these events determines the level of stress they experience.

5. Childhood stress

Apart, children also suffer from stress. Many kids are bullied at school or neglected at home. Others are abused physically, emotionally, or sexually. Many are anxious about tests or exams and school grades. Still others see their family torn apart by divorce, quarrelling and fighting. Also, stressed children may have nightmares, learning difficulties, depression, or a tendency to be withdrawn. Some seem unable to control their emotions. A child suffering from stress needs urgent help.


8 Effects of Stress on Your Body

Stress seems to worsen or increase the risk of conditions like 

1. Insomnia—sleep disorder

Sleeping problems is one of the effects of stress on our body. Stress keeps people awake at night due to worry, anxiety, or uncertainty about the future. Some people worry about their jobs, while others are concerned over family issues or health problems. 

2. Obesity

Stress can also cause obesity. A medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health. Thus resulting in severe health problems. Furthermore, obesity can be hereditary—According to the book Food Fight, “The genetics of obesity has been studied for decades. Much research has now been done on human genes and obesity. Sophisticated techniques are being used to identify genes that predispose people to weight gain, and to diseases like diabetes. In scientific parlance, 25 percent to 40 percent of the variability in population body weight can be explained by genes.” 

Obesity can also be attributed to the environment—The same book Food Fight states that: “Given that obesity is usually blamed on personal failing, these numbers underscore the importance of biology, but still, 60 percent or more of the influence can be attributed to the environment.” So conclusively, it can be as a result of both hereditary or environment.

3. Heart disease

Stress can make anyone’s heart beat rapidly, strongly or irregularly, and increase pulse rate as well as blood pressure. Over time, serious stress can damage the heart with increased wear, and tear for the reasons just mentioned.

4. Diabetes

Diabetes develops when the amount of sugar in your blood becomes very high. It could come as a result because of the following reasons. Either because your body doesn’t produce enough insulin, or because your body doesn’t respond to insulin.

5. Depression

Stress can make a person feel angry or hopeless, both of which can lead to depression. Also, stress can make you feel less able to maintain positive habits which are important to managing depression. This can make symptoms of depression feel more intense. Therefore, resulting in further stress, which can then make depression symptoms worse.

6. Emotional exhaustion

Stress can emotionally exhaust you completely. Thereby, making you feel tired most of the time. Additionally, emotional exhaustion is a state of feeling emotionally worn-out and drained as a result of accumulated stress from your personal or work lives, or a combination of both.

7. Deteriorating relationships

Stress can cause and have huge effect on relationships. Someone who is absorbed by their own stress may become less emotionally available to their partner. Subsequently, their partners will start thinking about leaving the relationship. Also, this then becomes an additional source of stress for the couple.

8. Disrupts healthy coping strategies

When people experience stress, they often stop engaging in some of the healthy coping strategies that usually help keep their mood on track. In other words, when stress triggers a lowered mood, it’s more likely that the person will skip their typical healthy mood regulation strategies, thus resulting in further mood problems.
