7 hormones every woman should know

Hormones have become one of those words we hear all the time, but rarely stop to define. They seem to explain everything and nothing at once. Feeling exhausted? Hormones. Can't sleep? Hormones. Mood feels off? Hormones.

The reality is that hormones influence almost every system in your body. They act as chemical messengers, traveling through your bloodstream to help regulate everything from your metabolism and menstrual cycle to your sleep, energy, stress response, and appetite.

While estrogen and progesterone tend to get the most attention, they're only part of a much bigger picture. Here's a closer look at seven hormones that play an important role in how you feel every day.

1. Cortisol

Often called the "stress hormone," cortisol helps your body respond to physical and emotional stress. It also supports healthy blood sugar levels, inflammation, metabolism, and even memory formation.

When cortisol stays elevated for long periods of time, you may notice changes like irregular periods, bloating, digestive changes, low energy, or difficulty feeling rested.

2. Insulin

Insulin helps move glucose from your bloodstream into your cells, where it's used for energy. When insulin isn't working efficiently, your body has a harder time regulating blood sugar.

Increased thirst, frequent urination, unexpected weight changes, or feeling tired after meals can all be signs that it's worth talking to your healthcare provider.

3. Melatonin

Melatonin helps regulate your body's internal clock, also known as your circadian rhythm. It signals when it's time to wind down for sleep and plays a role in your natural sleep-wake cycle.

If you struggle to fall asleep, feel awake late into the night, or experience daytime fatigue despite getting enough sleep, your circadian rhythm may be out of sync.

4. Thyroid Hormones

Your thyroid produces hormones that help regulate metabolism, energy production, body temperature, and many other everyday functions.

When thyroid hormone levels are too high, you may feel anxious, restless, or unusually hungry. When they're too low, symptoms often include fatigue, feeling cold, brain fog, or slowed metabolism.

5. Estrogen

Estrogen is one of the primary female sex hormones and supports everything from ovulation and the menstrual cycle to bone health and cardiovascular function.

Estrogen levels naturally fluctuate throughout life, but persistent imbalances may contribute to symptoms like headaches, irregular periods, low libido, or changes in body weight.

6. Progesterone

Progesterone works alongside estrogen to regulate the menstrual cycle and plays an especially important role in preparing and supporting the body during pregnancy.

Because progesterone naturally rises and falls throughout your cycle, changes in timing, flow, or cycle regularity can sometimes point to an imbalance worth discussing with your provider.

7. DHEA

DHEA is produced by your adrenal glands and serves as a building block for other hormones, including estrogen and testosterone. It also supports your body's response to stress and healthy aging.

Low DHEA levels may be associated with fatigue, reduced libido, low energy, or feeling run down, though these symptoms can have many possible causes.

The Bigger Picture

Hormones rarely work in isolation. They function as part of an interconnected system, which means changes in one hormone can influence others over time. That's also why many symptoms, like fatigue, poor sleep, mood changes, or irregular cycles, can have more than one possible explanation.

Supporting hormonal health starts with many of the same habits that support overall well-being: getting consistent sleep, eating balanced meals, managing stress, staying active, and following a routine that works for your body. If you're experiencing persistent symptoms or think something feels off, talk with your healthcare provider. They can recommend testing and help determine whether a hormone imbalance (or something else entirely) may be contributing.
