How Stress Affects Health

Stress is a normal part of everyday life.  At times it is a driving force for us to achieve better and succeed.  It is not always easy to define stress and it has different meaning for different people.  Mostly stress represents a negative feeling or experience and rather than a positive one. People vary in how they react to stress; same event can be stressful to one and not others. Similarly some recover quickly where others may not be able to cope.  Stress can affect both physical and mental health if it continues for longer duration.   

Stress can be defined as the brains response to any demand or pressure.  Chronic stress changes the balance of neurochemicals and hormones in the body and one may feel on high alert all the time. Chronic stress can also lead to structural changes in some areas of the brain.
Stress has been broadly classified into three groups.  First group comprises of the routine stresses brought about by day to day life e.g. work, family and other responsibilities.  Second group of stress is more severe in nature such as sudden change or loss in life e.g. divorce, losing a job, illness, death of a loved one etcetera.  Third group is commonly known as trauma like major accident, war, disaster, rape.  There is severe threat to life or integrity of an individual and most people find this type of stress difficult to manage and cope with.

Physical effects of stress can come across as loss of sleep, tiredness, appetite changes, aches and pains, headaches etcetera.  Stress can affect the immune system negatively and people become more prone to infections.  Long term stress and strain can lead to serious health problems and people become predisposed to develop conditions such as heart disease, high blood pressure, diabetes, and other illnesses.  Stress can also worsen existing physical health problems like asthma, diabetes, ischemic heart disease etcetera.

Stress has numerous mental health or psychological effects and sometimes stress is seen as such a mental health problem.   Most people cope with day to day life stress but some find it difficult and can develop anxiety, irritability, insomnia, fatigue, poor concentration and forgetfulness.  Some find it hard to deal with other people or social situations and may become recluse.  Chronic stress can lead to something called adjustment disorder which can present as severe anxiety, agitation, irritability, tearfulness, and suicidal thoughts, self-harm, depression.  People change life style and can engage in harmful activities like smoking, use of alcohol and drugs in an attempt to self-medicate to get some relief.  This often worsens the symptoms in long run and ultimately leads to drug addiction. It is know if the stress is removed from the person’s life, there is usually good recovery. Chronic fatigue syndrome is one of the outcomes of modern age life style and stress.

In contrast, when someone is traumatised by an extreme kind of stress like disaster, war, rape, and torture it can lead to severe and enduring mental illness. People can develop acute stress disorder, post-traumatic stress disorder and other  mood problems.  Repeated exposure to such stress can lead to chronic posttraumatic stress disorder, change in personality and even psychotic symptoms. Dissociation is very common and people can develop dissociative amnesia to multiple personality disorder. 

It is very important to identify stress early on and make necessary changes if possible to avoid long term problems. Talking to friends and family helps to overcome routine and day to day stress.  Sometimes people need help by professional counselling and at times medication if symptoms are severe.  There should be no hesitation in seeking appropriate help as failure to address the problem can lead to long term physical and mental health problems in addition to poor quality of life.  It is important to realise that the sometimes the solution can be in making simple life style changes. If that does not work one should seek help from a mental health professional who can be a counsellor, psychologist and psychiatrist.  It is also important to seek the right advice than get caught up into a cycle of doctor shopping.  People often end with cocktail of medications after having multiple investigations which are not often warranted.  It is often stigma and shame which holds people back from seeking the right help.


With any stressful situation, it is helpful to take a step back and try to think rationally. Regular exercise, good sleep, balanced eating and quality time with friends and family are helpful. It is necessary to keep balance between work and other leisure activities. Faith and spirituality are good for reducing stress and better coping. Avoiding drugs, alcohol and smoking are helpful in long run though they may seem attractive at the time. The most important step that leads to recovery is recognising that there is a problem.  Once acknowledged, recovery can begin.
