How Hormones Control Your Body: The Key Players in Health and Wellness
Estimated Reading Time: 14 minutes
|Feeling tired? Craving sugar? Or just snapped at your partner for no reason, and are wondering why your body is acting on some unknown script?
Okay, probably that's not you. But your hormones are directing behind the scenes.
Yes, hormones aren't just about periods and puberty. There are over 50 types of hormones inside your body that work 24/7 to run it smoothly. From calling shots on your energy to controlling your mood, skin, and even weight, hormones are the key players in overall wellness.
Hormones: What Exactly Are They?
Want to know what hormones are exactly? Let's make it simpler for you. You may call them postmen. And guess what they do? Send text messages from glands telling your body what to do.
In terms of biology,
-
Hormones are the chemical messengers secreted and released by different glands.
-
Together, these glands and hormones form your endocrine system, which can be better described as a command centre (you'll soon know why).
-
Hormones coordinate different functions in your body, from your metabolism to your sleep-wake cycle.
Myth-buster: Most people connect hormones with women! Though females are greatly affected by hormones, particularly during phases like puberty, pregnancy, and perimenopause, they are also responsible for men's vitality.
Meet Your Key Wellness Players a.k.a. Hormones
Scientists have identified over 50 hormones so far, but the real number may be even higher. Seems your body has more group chats going on than your college WhatsApp.
Covering all 50 hormones would take a Netflix series. So, in this blog, let's first talk about the crucial ones and how to balance those hormones naturally.

Cortisol: The CEO of Stress
Ever notice how deadlines, due bills, or even a messy house can leave you anxious and exhausted? That's the message from the stress hormone, cortisol. But wait, it's not always bad.
Produced by: Adrenal glands
What Cortisol Does?
The primary function of cortisol is to regulate stress or anxiety. Guess how it does it? It increases blood sugar levels that enhance the brain's use of glucose and prepare the body for action (think fight-or-flight mode). Here are other benefits:
-
Keeps your blood sugar steady between meals.
-
In small doses, it helps fight inflammation.
-
Influences how the body uses carbohydrates and fats.
-
Regulates the body's natural sleep-wake cycle.
What Happens When Cortisol Is Out of Balance?
Cortisol works best for a short time (in anxious moments). However, in the longer term, neither too much nor too little is good.
-
Too much cortisol: Anxiety, cortisol belly fat, sugar cravings, brain fog, poor sleep.
-
Too little cortisol: Fatigue, low blood pressure, dizziness.
Did you know? High cortisol for too long can even mess with your skin, leading to hormonal acne and premature aging. But here's some good news. Even a 10‑minute morning walk can lower cortisol spikes for the rest of the day.

Insulin: Your Sugar Traffic Police
Okay, does skipping breakfast leave you empty for the day ahead? Or do you feel sluggish after a carb-loaded meal? That's your insulin (a peptide hormone) at work.
Produced by: Pancreas (only when there are high blood sugar levels)
What Insulin Does?
Insulin indirectly keeps your energy steady. How?
-
Moves glucose from your food into your cells for energy.
-
Helps your body save extra glucose as fat for later use.
What Happens When Insulin Is Out of Balance?
-
Too much insulin: Fatigue, weight gain, brain fog, sugar cravings, increased risk of type 2 diabetes.
-
Too little insulin: High blood sugar, excessive thirst, frequent urination, poor vision, and unexplained weight loss.
In case of certain diseases like diabetes, the body fails to produce or utilize sufficient insulin. The fact might surprise you, but almost 1 in 3 adults has some degree of insulin resistance, often without realizing it.
-
Thyroid Hormones: Your Metabolism Manager
Eating clean still can't lose weight? Or even after proper sleep and exercise, you can't manage constant energy throughout the day? Probably you need to understand your thyroid hormones.
Produced by: Thyroid glands
What Thyroid Hormones Does?
Thyroid hormones, mainly triiodothyronine (T3) and thyroxine (T4), work like your body's thermostat. They control how fast or slow everything runs:
-
Control metabolism, which determines how quickly you burn calories.
-
Regulates energy levels, keeping you active and alert.
-
Maintains your body temperature (controlling if you feel hot or cold).
-
Plays a role in concentration and mental health.
-
Supports healthy hair, skin, and nails.
What Happens When Thyroid Hormones Are Out of Balance?
-
Hyperthyroidism (too much thyroid hormone): Weight loss, anxiety, racing heartbeat, insomnia, sweating, and tremors.
-
Hypothyroidism (too little thyroid hormone): Fatigue, weight gain, dry skin, hair loss, shivering, low mood, depression.
Iodine plays an important role in the synthesis of thyroid hormones. Approximately 200 million people worldwide have been diagnosed with thyroid disease. And women are five to eight times more likely than men to develop thyroid issues.
-
Estrogen & Progesterone: The Dynamic Duo
Ladies, remember that unexplainable mood swings, acne-filled skin, and bloating you get before periods? Well, that's not something random. But usually, these two hormones are calling the shots: estrogen and progesterone.
Produced by: Ovaries
What Estrogen & Progesterone Does?
Often identified as female hormones, estrogen and progesterone regulate the menstrual and pregnancy cycle in women. However, they are also present in males (though in lesser amounts) and contribute to their overall reproductive health.
Estrogen:
-
Regulates the menstrual cycle.
-
Keeps skin plump and youthful.
-
Supports bone strength.
-
Affects mood, memory, and libido.
Progesterone:
-
Prepares the body for pregnancy.
-
Calms the nervous system.
-
Balances estrogen to prevent symptoms from getting too intense.
-
Supports healthy sleep.
What Happens When They're Out of Sync?
-
Estrogen Dominance (too much estrogen): Bloating, mood swings, breast tenderness, irregular periods, migraines, and weight gain.
-
Low Estrogen: Hot flashes, sleepless nights, vaginal dryness, low libido, mood dips, bone loss, memory issues, and brain fog.
-
High Progesterone: Bloating, fatigue, tiredness, dizziness, panic attacks, and increased or decreased appetite.
-
Low Progesterone: Anxiety, irregular periods, difficulty sleeping, intense pre-menstrual symptoms.
If you're stressed quite often, it will also deplete your progesterone levels since your body uses the same raw materials to make cortisol.
-
Testosterone: More Than Just a 'Guy' Hormone
When you read testosterone, you might be relating it to a deep male voice, muscle gains, and (you already know what). However, here's the truth. Everyone has testosterone, and it plays a major role in how your body feels and functions.
Produced by: Testicles in males and ovaries/adrenal glands in females
What Testosterone Does?
Primarily, testosterone is responsible for the development of male reproductive organs and sexual characteristics, including:
-
Muscle growth and physical stamina.
-
A major player in the sex drive for both men and women.
-
Keeps bones strong and reduces fracture risks.
-
Supports fat-burning metabolism.
-
Vital for sperm production (in males).
-
Stimulates the production of red blood cells (RBCs).
What Happens When Testosterone Is Out of Balance?
-
Too low testosterone: Fatigue, low energy, low libido, loss of muscle mass, belly fat, trouble concentrating, and hair fall (particularly in women).
-
Too much testosterone: Oily skin, increased muscle mass, irritation, aggression, deepened voice, excessive body hair (women), and male pattern baldness (men).
Testosterone levels naturally start declining around 30 in men, dropping about 1% per year. Women also experience gradual dips, especially after menopause. Worried? Don't be. Instead, support your wellness with scientifically-proven supplements like Geranylgeraniol to maintain your ideal T-levels.
-
Somatropin: Human Growth Hormone (HGH)
You mightn't have heard of somatropin ever before, but it's an important growth hormone. If you have pulled an all‑nighter in college, survived on instant noodles, and still bounced back with your energetic version, thanks to HGH.
Produced by: Somatotropic cells within the anterior pituitary gland
What Somatropin Does?
As the name suggests, HGH promotes growth and development in kids. It also helps adults to stay energized, lean, and resilient.
What Happens When Somatropin Is Out of Balance?
-
Too little somatropin: Fatigue, low energy, poor immunity, delayed muscle recovery, low focus, trouble sleeping, shorter height
-
Too much somatropin: Extraordinary height, enlarged hands, feet, and facial features
Growth hormone deficiency is rare, but it can affect infants and children more than adults. Therefore, pediatricians recommend supplements containing growth factors like bovine colostrum to kids and infants.
-
Serotonin: Natural "Feel-Good" Messenger
Ever noticed how a random sunny morning uplifts your mood? Or seeing a random kid giggling leaves you for a damn productive day at work? That's your serotonin at work.
Produced by: 90% in the gastrointestinal tract, with small amounts in the brain.
What Serotonin Does?
The main role of serotonin is to regulate your mood and promote overall well-being. It also:
-
Regulates the natural sleep and wake cycle.
-
Controls learning, memory, and executive functions.
-
Influences appetite and digestion.
What Happens When Serotonin Is Out of Balance?
-
Too low serotonin: Mood swings, irritation, trouble sleeping, sugar-cravings, anxiety, and feeling 'off' for no reason.
-
Too much serotonin: Shivering, high fever, muscle rigidity, abnormal heart rhythm, confusion, seizures.
Try spending at least 10-15 minutes each day in sunlight. Reason? Sunlight triggers serotonin release, which is why you often feel happier on bright days.
-
Dopamine: Your Pleasure Maker
Remember smiling all day long after having a cozy 'date night' earlier or just by winning a simple pool game? That's the intense rush of dopamine.
Produced by: Mainly in the brain, with smaller amounts in the adrenal glands.
What Dopamine Does?
Known as the "reward and motivation hormone," dopamine shapes how you chase goals and experience pleasure.
-
Sparks motivation and focus.
-
Helps regulate learning, memory, and attention.
-
Supports movement and coordination.
-
Fuels your brain's reward system (why achievements feel so good).
What Happens When Dopamine Is Out of Balance?
-
Too little dopamine: Low energy, lack of motivation, trouble concentrating.
-
Too much dopamine: Restlessness, insomnia, impulsive or risky behavior, or addictive tendencies.
Excessively low levels of dopamine can lead to neurological disorders like Parkinson's disease.
-
Oxytocin: The Love & Bonding Hormone
Think of a warm hug from your mother instantly easing your stress. Or how comforting cuddling your pet makes you feel? That surge of comfort and connection is oxytocin showing up inside.
Produced by: Synthesized in the hypothalamus and released by the posterior pituitary gland
What Oxytocin Does?
Oxytocin, often released after a physical touch, social or sexual activity, is known as the 'love' or 'cuddle' hormone.
-
Builds trust and deepens relationships.
-
Promotes feelings of empathy and closeness.
-
Helps reduce stress and anxiety.
-
Plays a role in childbirth and breastfeeding.
-
Supports emotional well‑being and resilience.
What Happens When Oxytocin Is Out of Balance?

-
Too much oxytocin: Oversensitivity, social anxiety, etc.
Well, oxytocin isn't just about couples; it is also vital for the strong bond between mothers and their infants.
-
Endorphins: Your Natural Cheerleaders
Endorphins give you a sudden wave of relief and happiness. That intense happiness after a leg-breaking workout. Or, laughing with your best friend until your belly hurts.
Produced by: The Pituitary gland and the central nervous system
What Endorphins Do?
They act like natural painkillers and mood lifters, by:
-
Reducing pain and discomfort.
-
Triggering intense happiness and excitement.
-
Coping with stress and anxiety.
What Happens When Endorphins Are Out of Balance?
-
Too low endorphins: Low moods, stress, increased sensitivity to pain, and difficulty handling challenges.
-
Too many endorphins: Very rare but can affect your ability to feel pain appropriately.
The group of four hormones, dopamine, endorphins, oxytocin, and serotonin, together called the 'happy hormones', promotes happiness and pleasure in individuals.
-
Melatonin: Your Sleep Scheduler
Ever started yawning, as the lights dimmed, even when you weren't feeling tired at all? That's the signal from your melatonin hormone.
Produced by: The pineal gland in the brain, especially in response to darkness
What Melatonin Does?
Often called the 'sleep hormone', melatonin mainly keeps your internal clock (circadian rhythm) in check.
-
Signals your body "it's bedtime"'
-
Regulates the sleep-wake cycle
-
Supports recovery and repair during rest
-
Adjusts to seasonal and environmental light changes
What Happens When Melatonin Is Out of Balance?
-
Too low melatonin: Insomnia, restless nights, frequent waking, brain fog, fatigue
-
Too high melatonin: Vivid dreams, headaches, etc.
Melatonin also possesses antioxidative properties, which build your immune response. To boost melatonin production, avoid screens and bright light before sleeping.
-
Adrenaline: That Instant Energy Hormone
Want to know about how adrenaline kicks in? Well, it's your heart racing before a big presentation, that sudden energy flood before river rafting.
Produced by: The adrenal glands
What Adrenaline Does?
Adrenaline, also called epinephrine, is your body’s "fight‑or‑flight" hormone.
-
Increases heart rate
-
Enhances blood flow to muscles
-
Boosts alertness and focus instantly
-
Raises blood sugar levels for quick energy
-
Expands airways to help you breathe easier
-
Prepares the body to respond quickly to stress or danger
What Happens When Adrenaline Is Out of Balance?
-
Too low adrenaline: Fatigue, lack of motivation, poor stress response, and trouble focusing
-
Too much adrenaline: Anxiety, rapid heartbeat, high blood sugars, insomnia, hypertension, and constant fear of missing out (FOMO)
Dopamine and adrenaline, together, are called the exciting hormones, since they play significant roles in the body's responses to excitement, stress, and pleasure.
-
Leptin & Ghrelin: The Hunger Regulators
We all have been through appetite confusion. Some days we feel full right after having a cucumber salad, on other days, even the whole pizza and chocolate lava cake can't sustain us. Here comes leptin (satiety hormone) and ghrelin (hunger hormone).
Produced by:
-
Leptin: Fat cells (adipocytes)
-
Ghrelin: In the stomach
What These Hunger Hormones Do?
Both leptin and ghrelin work in contrast to each other. While leptin signals your brain "I'm full", ghrelin talks about "feed me more.".
-
Leptin: Tells your brain you’ve had enough food and can stop eating. It also helps regulate long‑term energy balance.
-
Ghrelin: Stimulates appetite and encourages you to eat, especially when your stomach is empty.
What Happens When They're Out of Balance?
-
Too low leptin or leptin resistance: Constant hunger, difficulty feeling full, and potential weight gain.
-
Too much ghrelin: Increased appetite, frequent cravings, and overeating.
-
Too little ghrelin: Low appetite and possible unintentional weight loss.
Let's make it simple for you. When leptin and ghrelin are in sync, you feel satisfied and energized. And, when they're not, your body would probably be stuck in an endless eating loop.
Well, Balancing Your Hormones Naturally Isn't a 'Tough Task'
See, hormones really are the silent directors of your well‑being. Any imbalance can cause different health concerns from cortisol belly to hormonal acne. That rises another question, how to balance hormones?
The good news? To begin with you don’t need medications or therapies. A few practical, little habits can help you to feel like your best self again.
-
Eat balanced meals. Combine protein, fiber, healthy fats, anti-inflammatory meals, in the best way possible.
-
Limit consumption of processed foods, alcohol, and quit smoking to support your cortisol and insulin.
-
Aim for at least 7-9 hours of sleep each day. Good sleep keeps cortisol, melatonin, and hunger hormones in sync.
-
Move your body daily. Exercise boosts endorphins, dopamine, and testosterone while lowering cortisol.
-
Spend some time in sunlight to regulate serotonin and melatonin naturally.
-
Meditation, yoga, or even deep breathing reduces cortisol and adrenaline rushes.
-
Don't neglect your social bonds. Healthy relationships fuel oxytocin and dopamine for emotional well‑being.
The Bottom Line
Hormones aren't just the neurochemicals. They control the entire balance of your life. Whether it's mood, metabolism, sleep, or energy, hormones direct every single script of your life.
And when they're not in sync, even simpler tasks can feel overwhelming.
Simple lifestyle changes like eating balanced meals, staying active, managing stress, and sleeping well can go a long way in keeping your hormones (and you) happy.
