If you’re over 45 or so and you’ve ever wondered why the whole energy, sleep, and mood parts of life aren’t quite as seamless as they used to be, the answer often comes down to hormones, especially our sex hormones. 

‍

Produced by different glands throughout the body, hormones are the internal messengers that keep countless systems running smoothly. They travel through your bloodstream, regulating everything from metabolism to immunity to sleep to stress to sex.

‍

Among the dozens of hormones at work in our bodies 24/7, four stand out as key players in the vitality and longevity departments: estradiol, progesterone, testosterone, and DHEA. Commonly thought of as our sex hormones, they do far more than just influence libido. When levels are optimized and balanced, they support your over-all energy, your restorative deep sleep and manageable moods. But as the hormonal dials start to turn down with age, the harmony fades and the static creeps in.

‍

So how do you help your hormones do their best work for the long haul? Let’s start with what you can do to keep your hormones well-tuned:

Give your hormones some TLC.

Hormones don’t just switch off with age — they dim gradually, like a light on a slow fade. Levels drop over time, and the body’s ability to “hear” hormonal messages weakens. Receptors lose sensitivity; the system becomes less efficient.

‍

That’s why so many people in midlife notice changes in sleep, stamina, or libido even when lab tests look “normal.” What’s normal for the general population isn’t always optimal for you. Optimizing levels and restoring balance — through smart lifestyle choices, and when indicated, carefully supervised hormone therapy — can make a world of difference.

‍

Here’s the good news: your daily habits profoundly affect how well hormones work. How you eat, move, rest, and manage stress can either steady or scramble those internal signals. In short, you can create a hormone-friendly lifestyle that helps your body, with or without medical support.

‍

Sex hormones play a big role in longevity.

So, what do these four hormones have to do with longevity? Quite a bit more than most people realize. When estradiol, progesterone, testosterone, and DHEA are optimized and balanced, they create a kind of biological symphony that supports nearly every system in the body — muscles, bones, brain, heart, skin, and mood. Together, they influence how efficiently your body burns fuel, repairs damaged cells, and resists disease.

‍

As these levels decline, recovery and resilience decline too. That’s why post-menopause (and, for men, later midlife) often brings noticeable changes in vitality. But decline doesn’t have to mean downfall. With the right support —think lifestyle first, then hormone replacement therapy (HRT) when appropriate — you can slow or even stop the hormonal slide. 

‍

One large observational study found that postmenopausal women who used hormone therapy had a “biologically younger” profile compared to non-users, suggesting slower cellular aging . Other analyses show that estrogen-based HRT can reduce the risk of heart disease and premature death when started around the time of menopause.

DHEA: The “Mother Hormone” of vitality.

DHEA, short for dehydroepiandrosterone, is not easy to say, but certainly worth knowing about. Produced mostly in the adrenal glands, DHEA acts as a “mother hormone,” helping to build both estrogen and testosterone. It peaks in early adulthood and slowly declines with time.

‍

When DHEA drops, you may notice lower energy, loss of muscle tone, drier skin, diminished libido, or mood changes. Research suggests DHEA supplementation may reduce fat mass and increase lean mass in older adults, while in women, it can improve sexual satisfaction and vaginal comfort after menopause.

‍

To increase levels, many people will consider options like prescription DHEA gels, creams or supplements. But remember, DHEA isn’t something to take casually. Because it influences estrogen and testosterone, it requires precise dosing and close medical oversight. For those navigating post-menopause or andropause, small, supervised doses can help restore balance — the goal is to feel energized, not overstimulated.

Estradiol: the glow and the safeguard.

Estradiol (E2) is the most potent and protective form of estrogen. Before menopause, it’s made primarily by the ovaries; afterward, smaller amounts come from the adrenal glands and fat tissue. The sharp decline after menopause contributes to many of the changes women notice in midlife — bone loss, brain fog, hot flashes, and shifts in body composition.

‍

Estradiol is a multitasker: it maintains bone density, keeps blood vessels flexible, supports mood and cognition, and promotes hydrated, supple skin. It also protects vaginal and urinary health — two issues few women are warned about before menopause but can have a profoundly negative impact on quality of life. Studies show that estradiol therapy can even reduce all-cause mortality when started at the right time.

‍

When estradiol levels fall, risks for osteoporosis and heart disease rise. That’s why, for many women, hormone replacement therapy (HRT) that includes estradiol, especially when begun near menopause, can be both restorative and preventive. One major study found that HRT users had a 20-50% lower risk of death compared to non-users.

‍

While some patients may opt for pharmaceutical HRT options, in my practice we prefer bio-identical hormones from reputable compounding pharmacies. Used responsibly, HRT can ease debilitating symptoms and strengthen long-term health. Re-analysis of the landmark Women’s Health Initiative shows that when hormone therapy is initiated before about age 60, most safety concerns drop dramatically. Although some studies show a small uptick in breast cancer, particularly in those doing HRT for 5 years or more, that small increase largely is outweighed by significant reduction in heart attack and stroke risk — still the leading killers of women and men.

‍

In short, for many women, HRT is about building a bridge back to maintaining vitality, while also protecting the systems that help you age well. Estradiol is one of the body’s great defenders. Keeping it in the optimal range can go a long way toward helping you age better, and more gradually.

Progesterone: The calm in the storm

If estradiol is the spark, progesterone is the stabilizer — the hormone that grounds and soothes. During the years leading up to menopause, progesterone is usually the first to fall as ovulation becomes irregular. This creates estrogen dominance — too much estrogen relative to progesterone — leading to bloating, heavy periods, mood swings, and restless sleep.

‍

Restoring progesterone (in its bioidentical form) helps rebalance that relationship. Many women find it improves sleep, steadies mood, and reduces anxiety. It also supports bone health, cardiovascular function, and cognitive performance. Studies show it can lessen hot flashes and improve sleep in women experiencing menopausal symptoms.

‍

Beyond menopause, progesterone remains a quiet ally in longevity. It strengthens bone, supports collagen production for smoother skin, balances fluid levels, and helps stabilize metabolism. Paired with steady exercise, mindful stress management, and nutrient-rich foods, progesterone becomes a gentle anchor — keeping you steady as your body adapts to change.

Testosterone: Not just for men

Though it’s often labeled the “male hormone,” testosterone is essential for everyone. In men, it supports muscle, bone, mood, and sexual health. In women, small but steady amounts sustain energy, confidence, and libido — all of which often fade after menopause.

‍

Men’s  testosterone levels decline, about 1% per year after age 30, but lifestyle factors make a bigger difference than age alone. Weight gain, inactivity, poor sleep, and chronic stress speed up the drop. Belly fat even converts testosterone into estrogen, contributing to lower drive and energy.

‍

The antidotes? Sleep, strength training, and stress control. Resistance exercise and restorative rest naturally boost testosterone production, helping maintain lean muscle and sharper focus.

‍

For women, microdoses of testosterone can enhance sexual satisfaction, energy, and mental clarity. Because levels fall sharply after menopause, low-dose therapy can be transformative — but must be carefully monitored, as too much can bring with it side effects like acne, excess hair, or irritability.

‍

If you’re considering supplementation, skip the “testosterone mills” and work only with a qualified physician. Think of therapy as a fine-tuning tool, not a quick fix. When used appropriately, testosterone therapy can help preserve lean tissue, bone density, and vitality — the cornerstones of healthy aging.

Supporting your hormones naturally.

In addition to replenishing hormones as they drop around menopause, it’s worth remembering that your daily habits have a profound influence on hormonal balance. Consistent lifestyle habits are your ally – and doing them daily will create the conditions your body needs to keep your hormones happy. Top on the hormone helper list:

‍

• Regular, enjoyable movement — not punishing workouts -- keeps metabolism humming and stress hormones balanced. 
• A nutrient-dense diet full of vegetables, fruits, healthy fats, and high-quality proteins supplies the raw materials for hormone production.
• Keep refined sugar, processed food, and alcohol to an absolute minimum. (More than one drink a day can interfere with estrogen metabolism and ramp up oxidative stress.)
• Load up on foods rich in phytoestrogens, the natural plant compounds that support estrogen balance, such as flaxseeds, fermented soy (tofu, tempeh), and cruciferous vegetables like broccoli and kale.
• Restorative sleep – it’s the nightly time when hormones reset, repair, and rebuild. 
• Add stress-taming practices like yoga, meditation, time in nature, sauna sessions, etc.

BOTTOM LINE: Hormones aren’t just about sex and reproduction — they’re central to how well we age. Restoring and balancing estradiol, progesterone, testosterone, and DHEA isn’t about chasing youth; it’s about working with your biology to extend vitality and resilience.
