How many hormones are there in the human body?


The human body produces more than 200 hormones and hormone-like messengers. Beyond the familiar sex hormones (estrogen, progesterone, testosterone), thyroid hormones, and adrenal hormones like cortisol and DHEA, this includes insulin, growth hormone, melatonin, leptin, ghrelin, oxytocin, vasopressin, and many more. Broadly defined, all the chemical messengers your body makes to communicate between cells function as hormones.

When I mention Hormones in the human body, what do you imagine I’m referring to? Sex hormones? Like estrogen, progesterone and testosterone? Or thyroid hormones? Adrenal hormones like cortisol and DHEA? Insulin? Growth hormone? Melatonin?

I’m talking about all your Hormones. All of the above plus - leptin, ghrelin, melanocyte stimulating hormone, erythropoietin, vasopressin, oxytocin, renin, angiotensin, parathyroid hormone.

And all your neurotransmitters - like dopamine, serotonin, acetylcholine, GABA, norepinephrine.

And all your immune factors - like interferon, interleukin. Your body produces are more than 200 hormones!

All the chemicals your body makes that act as messengers are essentially Hormones!

You see, that is what Hormones are – messengers. Hormones communicate to your cells, your tissues, your organs what’s going on in another part of your body as well as what’s going on outside of your body!

For instance, when the sun goes down the pink rays of dusk block the blue light of day. These pink light waves effectively turn on your pineal gland – a tiny organ in your brain- and tells it to start making Melatonin. So you can sleep. The light energy outside of your body affects hormonal production inside your body. Melatonin is the nocturnal messenger hormone that induces sleep and shuts down your daytime hormone activity, so your nighttime hormones can do their job. Like turning on your immune system to protect you from invasion, infection, and cancer. That’s why when you do not get enough sleep, you’re more likely to get sick.

Hormones tell your cells what to do.

Produce more energy. Make more enzymes. Reproduce and make new you. Go to sleep. Clean house. Get rid of invaders. Even tell cells when to die (especially cancer cells). All communication within your body is directed by your hormones. When you’re sick and tired, you’re experiencing hormonal miscommunication.

The secret to balancing your hormones, neurotransmitters, and immune factors is to support your hypothalamus. Why? Because your hypothalamus is the maestro of your symphony of hormones. 

Think of all your body as hardware and all your hormones as software. Your hypothalamus is your operating system. Your hypothalamus controls all your hormones, directs your neurotransmitter production and your immune function.

Supporting your hypothalamus is crucial to keeping your Hormones in Harmony!

Frequently Asked Questions

Are neurotransmitters considered hormones?

In the broadest sense, neurotransmitters act as part of the body's messenger system alongside hormones. Chemicals like dopamine, serotonin, acetylcholine, GABA, and norepinephrine carry signals between nerve cells. While neurotransmitters and classic hormones have technical differences in how they travel and act, both are chemical messengers, which is why hormonal balance and neurotransmitter balance are closely connected.

What are the main types of hormones in the body?

Hormones can be grouped into several broad categories: sex hormones (estrogen, progesterone, testosterone), thyroid hormones, adrenal hormones (cortisol, DHEA), and metabolic hormones (insulin, leptin, ghrelin). There are also hormones like growth hormone, melatonin, oxytocin, vasopressin, and parathyroid hormone, plus neurotransmitters and immune factors such as interferon and interleukin that act as messengers too.

How does sleep affect your hormones?

Sleep is tightly regulated by hormones and, in turn, regulates them. As daylight fades, the pineal gland releases melatonin, the nocturnal messenger that induces sleep and quiets daytime hormone activity so nighttime hormones can work. This includes activating parts of the immune system. Because of this, not getting enough sleep can disrupt hormonal balance and immune function, which is part of why poor sleep is linked to getting sick more easily.

What controls all the hormones in the body?

The hypothalamus is often described as the coordinator of the body's hormones. Sometimes called the "maestro" of the endocrine system, it controls hormone production, directs neurotransmitter output, and influences immune function. A helpful analogy: if the body is hardware and hormones are software, the hypothalamus is the operating system that runs and coordinates everything, which is why supporting it is central to overall hormone balance.

Frequently Asked Questions

What is the Sunshine Protection Act?

The Sunshine Protection Act (H.R. 139) is federal legislation that would make daylight saving time permanent nationwide, ending the twice-yearly clock change. The U.S. House passed it on July 14, 2026, and it now awaits action in the Senate.

What's the difference between permanent daylight saving time and permanent standard time?

Both would end clock changes, but in opposite directions. Permanent standard time keeps clocks aligned with the sun so light arrives earlier in the morning. Permanent daylight saving time shifts clocks later year-round, meaning darker mornings — especially in winter — and more evening light.

Why do some sleep experts favor permanent standard time?

Many circadian researchers and the American Academy of Sleep Medicine have expressed support for permanent standard time, citing its closer alignment with natural light and the body's internal clock. The concern with permanent daylight saving time is the loss of morning light, which can influence sleep timing.

How does morning light affect the body?

Morning light exposure can help signal the brain's internal clock, which may support healthy sleep-wake timing, alertness, and hormone rhythms. Reduced morning light may make it harder for the body's clock to stay in sync. Individual responses vary, so speak with your provider about your own sleep concerns.

What is the suprachiasmatic nucleus (SCN)?

The SCN is a small cluster of neurons in the hypothalamus that acts as the body's master clock. It responds to light and dark cues and helps coordinate daily rhythms in sleep, hormone release, and metabolism.
