Stress can have far reaching effects on our health and it affects almost all the organ systems in the body. Having a knowledge of all these is important and it is so is the need to eliminate / resolve the stressful situation at the earliest.
1 Musculoskeletal System
When the body is stressed, muscles tense up. Muscle tension is almost a reflex reaction to stress — the body’s way of guarding against injury and pain.
Relaxation techniques have been shown to effectively reduce muscle tension, decrease the incidence of certain stress-related disorders, such as headache, and increase a sense of well-being.
2 Respiratory System
Stress can make you breathe harder. That’s not a problem for most people, but for those with asthma or a lung disease such as emphysema, getting the oxygen you need to breathe easier can be difficult.
Working with a psychologist to develop relaxation and breathing strategies can help.
3 Cardiovascular System
The heart and blood vessels comprise the two elements of the cardiovascular system that work together in providing nourishment and oxygen to the organs of the body. The activity of these two elements is also coordinated in the body’s response to stress. Acute stress — stress that is momentary or short-term such as meeting deadlines, being stuck in traffic or suddenly slamming on the brakes to avoid an accident — causes an increase in heart rate and stronger contractions of the heart muscle, with the stress hormones — adrenaline, noradrenaline and cortisol — acting as messengers for these effects. In addition, the blood vessels that direct blood to the large muscles and the heart dilate, thereby increasing the amount of blood pumped to these parts of the body and elevating blood pressure. This is also known as the fight or flight response. Once the acute stress episode has passed, the body returns to its normal state.
Chronic stress, or a constant stress experienced over a prolonged period of time, can contribute to long-term problems for heart and blood vessels. The consistent and ongoing increase in heart rate, and the elevated levels of stress hormones and of blood pressure, can take a toll on the body. This long-term ongoing stress can increase the risk for hypertension, heart attack or stroke.
4 Endocrine System
When the body is stressed, the hypothalamus signals the autonomic nervous system and the pituitary gland and the process is started to produce epinephrine and cortisol, sometimes called the “stress hormones.”
5 Gastrointestinal System
When you’re stressed, you may eat much more or much less than you usually do. If you eat more or different foods, or increase your use of alcohol or tobacco, you can experience heartburn or acid reflux. Stress or exhaustion can also increase the severity of heartburn pain.
When you’re stressed, your brain becomes more alert to sensations in your stomach. Your stomach can react with “butterflies” or even nausea or pain. You may vomit if the stress is severe enough. And, if the stress becomes chronic, you may develop ulcers or severe stomach pain even without ulcers.
Stress can affect digestion, and what nutrients your intestines absorb. It can also affect how fast food moves through your body. You may find that you have either diarrhea or constipation.
6 Nervous System
The nervous system has several divisions: the central division involving the brain and spinal cord and the peripheral division consisting of the autonomic and somatic nervous systems. The autonomic nervous system (ANS) has a direct role in physical response to stress and is divided into the sympathetic nervous system (SNS), and the parasympathetic nervous system (PNS).
When the body is stressed, the SNS generates what is known as the “fight or flight” response. The body shifts all of its energy resources toward fighting off a life threat, or fleeing from an enemy. The SNS signals the adrenal glands to release hormones called adrenalin and cortisol. These hormones cause the heart to beat faster, respiration rate to increase, blood vessels in the arms and legs to dilate, digestive process to change and glucose levels (sugar energy) in the bloodstream to increase to deal with the emergency.
7 Male Reproductive System
Stress causes the body to release the hormone cortisol, which is produced by the adrenal glands. Cortisol is important to blood pressure regulation and the normal functioning of several body systems including cardiovascular, circulatory and male reproduction. Excess amounts of cortisol can affect the normal biochemical functioning of the male reproductive system.
Chronic stress, ongoing stress over an extended period of time, can affect testosterone production, sperm production and maturation, and even cause erectile dysfunction or impotence.
8 Female Reproductive System
Stress may affect menstruation among adolescent girls and women in several ways. For example, high levels of stress may be associated with absent or irregular menstrual cycles, more painful periods and changes in the length of cycles.
Premenstrual Syndrome (PMS)
Stress may make premenstrual symptoms worse or more difficult to cope with and pre-menses symptoms may be stressful for many women. These symptoms include cramping, fluid retention and bloating, negative mood (feeling irritable and “blue”) and mood swings.
As menopause approaches, hormone levels fluctuate rapidly. These changes are associated with anxiety, mood swings and feelings of distress. Thus menopause can be a stressor in and of itself. Some of the physical changes associated with menopause, especially hot flashes, can be difficult to cope with. Furthermore, emotional distress may cause the physical symptoms to be worse. For example, women who are more anxious may experience an increased number of hot flashes and/or more severe or intense hot flashes.
Women juggle personal, family, professional, financial and a broad range of other demands across their life span. Stress, distraction, fatigue, etc., may reduce sexual desire — especially when women are simultaneously caring for young children or other ill family members, coping with chronic medical problems, feeling depressed, experiencing relationship difficulties or abuse, dealing with work problems, etc.
