Cortisol is a steroid multipurpose hormone produced by the adrenal glands located above the kidneys. Besides other functions, cortisol is the main “stress hormone” because it helps you and your child respond efficiently to stress.
In stressful situations, the hormone, together with adrenaline, helps to increase heart rate, elevate blood pressure, and sharpen the senses, all of which are essential for survival. This hormonal response is evolutionarily designed to help the human body react swiftly to physical or psychological danger.
Of note, however, cortisol doesn’t just influence our immediate stress response; it also has long-term effects on the body. Chronic stress can lead to consistently high levels of cortisol, which can contribute to a range of health problems over time.
Therefore, understanding how the hormone functions in the body and how to manage its levels is essential for maintaining overall health and well-being.
Why is Cortisol a Stress Hormone?
When a person faces sudden stressful situations, the adrenal glands release cortisol hormone in addition to adrenaline, into the bloodstream. Actually, adrenaline, also released by neurons in the medulla oblongata, takes center stage in the immediate response to stress. It is a quick-acting hormone released within seconds of encountering stressful moments.
This rush equips the body with a heightened state of alertness and physical capabilities to deal with the perceived danger, causing the stress.
For example, upon encountering a wild animal like a bear while hiking in the woods, the following steps explain the hormonal responses.
- Encounter with the Bear: You see a bear in the woods, triggering the hypothalamus (part of your brain) to perceive danger.
- Hormonal Surge: The hypothalamus in the brain sends signals to your adrenal glands to release adrenaline and cortisol.
- Adrenaline Rush: The adrenal medulla (inner layer of adrenal glands) releases a burst of adrenaline hormone within seconds. This gives you an immediate boost of energy – increased heart rate, blood pressure, and stronger muscle contractions.
- Cortisol Joins the Party: While adrenaline is the initial jolt, the adrenal cortex (outer layer of adrenal glands) starts releasing cortisol. It takes minutes to hours to FULLY rise to the occasion, but its effects are more sustained.
- Fight or Flight: Fueled by adrenaline and cortisol, your body prepares for action. The increased blood sugar provides readily available energy, while hormones help mobilize stored fats and proteins for additional fuel. Your heightened senses and stronger muscles allow you to either confront the bear (fight) or flee the scene (flight).
- After the Rush: A while later when the bear is no longer a threat, cortisol levels start to return to normal. Your body calms down, and other systems like digestion, which were put on hold, resume their normal functions.
In brief …
Adrenaline: This is the surge you feel immediately. Your heart races, breathing increases, and you get a burst of energy to run away (fight) or climb a tree (flight). Cortisol: Once you are safe, cortisol kicks in. It helps your body stay alert for potential danger while providing the energy to cope with the situation, like finding shelter or planning your next move.
In essence, adrenaline provides the initial jolt of energy and heightened physical response for immediate action in a stressful situation. On the other hand, cortisol takes the backseat, but joins the party soon after for sustained energy management. The two work together as a team to help the body survive stressful encounters.
The Major Functions of Cortisol:
Despite its association with stress, cortisol is a multifunctional hormone that plays diverse roles in the body,
- Management of Stress: As illustrated above, cortisol is a key player in the body’s response to stress. When you experience stress, cortisol levels rise, giving you a surge of energy to handle the situation.
- Regulation of Blood Sugar: Cortisol helps increase blood sugar (glucose) levels by stimulating the liver to release stored glucose and promoting the conversion of proteins and fats into glucose. This provides readily available energy during stressful times.
- Modulation of Immune System: Cortisol helps dampen the immune system’s inflammatory response. While this can be helpful in the short term to conserve resources for immediate needs, chronically high cortisol levels can weaken the immune system.
- Metabolism Control: Cortisol influences how your body uses carbohydrates, fats, and proteins. It can promote the breakdown of muscle tissue and fat stores for energy during stress.
- Maintenance of Blood Pressure: Cortisol influences blood pressure regulation by enhancing the action of vasoconstrictors, which narrow blood vessels, thereby increasing blood pressure. This is particularly important during stressful situations when the body needs to redirect blood flow to vital organs and tissues to support the stress response.
- Management of Sleep-wake Cycle: Cortisol has a natural rhythm, following a circadian cycle. Levels are highest in the morning to help you wake up and gradually decrease throughout the day. It promotes relaxation during the day, and prepares the body for sleep at night. Early in the night it is replaced by melatonin, “hormone of darkness“, because its production is stimulated by darkness and inhibited by light. Melatonin helps signal to the body that it is time to sleep, promoting relaxation and drowsiness.
Maintaining a Balance of Cortisol Hormone in Your Child is Key:
While cortisol is vital for maintaining homeostasis and coping with stress, dysregulation of its levels can lead to various health issues.
- Too much cortisol: Chronic stress can lead to elevated cortisol levels, which can contribute to weight gain, digestive issues, high blood pressure, headaches, anxiety, and difficulty sleeping (insomnia).
- Too little cortisol: Can lead to fatigue, weakness, weight loss, and difficulty regulating blood sugar levels (hypoglycemia).
The Long-term Effects of Low & High Cortisol Levels:
While cortisol is essential in stress response, chronically high levels of the hormone can be harmful to your health and that of your child. Low and high levels of the hormone can be an indicator of chronic stress, which can have detrimental effects on physical and mental health.
Here is an overview of some potential consequences:
1. Physical Health:
Growth and development: High cortisol can disrupt growth hormone production, leading to stunted growth, delayed puberty, and weakened bones.
Metabolic problems: Chronically high cortisol can contribute to weight gain, especially around the abdomen and face, and increase the risk of developing type 2 diabetes, high blood pressure, and cholesterol imbalances.
Weakened immune system: Cortisol suppresses the immune system, making children more susceptible to infections and illnesses.
Headaches and digestive issues: Chronic stress can manifest in physical symptoms like headaches, stomachaches, and other digestive problems.
2. Mental Health:
Behavioral and emotional problems: Children with high cortisol levels may exhibit anxiety, depression, irritability, hyperactivity, and difficulty concentrating. They may also be more prone to behavioral problems like aggression, impulsivity, and withdrawal.
Cognitive development: Chronic stress can negatively impact brain development, leading to learning difficulties, memory problems, and attention deficits.
Increased risk of mental health disorders: Children with prolonged exposure to high cortisol are at higher risk of developing mental health disorders like anxiety disorders, depression, and post-traumatic stress disorder (PTSD) later in life.
3. Social and Emotional Development:
Difficulties with relationships: Children with high cortisol levels may struggle to build and maintain healthy relationships with family and friends due to emotional dysregulation and challenges with communication.
Poor self-esteem: Chronic stress can contribute to low self-esteem and negative self-image, further impacting emotional well-being.
Academic difficulties: Stress can hinder concentration and learning, leading to academic struggles and decreased motivation.
Besides, elevated levels of cortisol can be indicative of Cushing’s syndrome:
Cushing’s syndrome is a hormonal condition that occurs when a person’s cortisol levels are too high. It can have severe and wide-ranging effects on the body.
MedicalNewsToday
Cushing’s syndrome is usually caused by using medications that lead to high levels of cortisol in the body i.e. glucocorticoids. Sometimes it may arise due to cancerous tumors!
Other effects of bad levels of cortisol:
- Thin arms and legs
- Stretch marks
- Acne
- Mood swings
- Poor sleep
- Fatigue
- Weak bones
- Increased risk of infections
If you notice any of these signs in your child, it is important to see a doctor soon enough. They will be able to do a blood or saliva test to measure cortisol levels. If the test results show that your child’s cortisol levels are high, the doctor will likely recommend treatment to address the underlying cause of the problem.
What is the Right Amount of Cortisol Hormone Levels in Your Child?
Unfortunately, there’s no single “right” amount of cortisol for all children. Determining appropriate levels involves several factors, including:
- Age: Cortisol levels naturally fluctuate throughout childhood. Typically, they are highest in newborns and gradually decrease through adolescence.
- Time of day: Cortisol follows a daily cycle, peaking shortly after waking and gradually declining throughout the day.
- Stress levels: Cortisol rises in response to stress, so even within a day, levels can vary significantly depending on individual experience.
- Underlying health conditions: Some medical conditions can affect cortisol production, making it essential to consider the child’s overall health picture.
Therefore, a doctor would assess cortisol levels in the context of these factors rather than focusing on a single universal value. They may order blood or saliva tests at specific times (usually morning) to get a complete picture.
According to ebmconsult, here is a general reference range for cortisol levels in adults and children, measured in mcg/dL:
Adults:
- 8 AM to noon: 5-25 mcg/dL (138-690 nmol/L)
- 8 PM to 8 AM: 0-10 mcg/dL (0-276 nmol/L)* (PDR)
Adult/elderly:
- 8 AM: 5-23 mcg/dL (138-635 nmol/L)
- 4 PM: 3-13 mcg/dL (83-359 nmol/L)
Child: 1-16 years:
- 8 AM: 3-21 mcg/dL
- 4 PM: 3-10 mcg/dL
Newborn:
- 1-24 mcg/dL
Remember, these are just broad guidelines and should not be used for self-diagnosis.
If you are concerned about your child’s cortisol levels, consult a pediatrician. They can interpret the results within your child’s specific context and recommend further investigations or interventions if necessary.
What Factors at Home Can Trigger High Levels of Cortisol Hormone in Your Child?
High cortisol hormone levels can be an indicator of chronic stress, which can have detrimental effects on the physical and mental health of your child. Understanding the conditions and environments that contribute to elevated cortisol in children can help parents create a more supportive and stress-reducing home environment.
Here are some key factors that can lead to high cortisol hormone levels in your child:
1. Parenting Practices:
- Harsh or punitive parenting: Frequent yelling, physical punishment, and overly critical behavior can trigger the fight-or-flight response in children, leading to cortisol spikes.
- Inconsistent parenting: Unpredictable discipline and unclear expectations can create a stressful environment for children, disrupting their sense of security and control.
- Emotionally neglectful parenting: A lack of warmth, responsiveness, and affection can make children feel unsupported and insecure, impacting their stress response.
