Low libido is one of the most common sexual complaints for both men and women, and it rarely has a single cause. The good news is that sexual desire responds to a wide range of changes, from how you move your body to what you eat, how you sleep, and even how you think about arousal in the first place. Here’s what actually works.
Understand How Your Desire Style Works
Not everyone experiences desire the same way, and misunderstanding your own pattern can make you think something is wrong when it isn’t. Sexual desire generally falls into two categories: spontaneous and responsive.
Spontaneous desire is what most people picture. It shows up out of nowhere, before any physical contact. Responsive desire, on the other hand, only kicks in after intimacy has already started. People with responsive desire often don’t feel turned on until several minutes into foreplay. That doesn’t mean their desire is broken. It means their arousal needs a runway.
If you have responsive desire, the key is creating the right conditions before expecting to feel anything. Long hugs, cuddling, back rubs, showering together, or other forms of sensual (not necessarily sexual) touch can help your mind and body relax enough for desire to build. Waiting around for a spontaneous urge that may never come is a recipe for frustration. Instead, start with physical closeness and let arousal follow.
Exercise Changes Your Hormonal Landscape
Regular physical activity is one of the most reliable ways to increase sexual desire, and the effect works through multiple pathways at once. Exercise positively affects cortisol, estrogen, testosterone, and oxytocin, all of which play roles in arousal. A nine-week randomized trial found that 30 minutes of combined strength training and cardio three times a week, performed at 70 to 85 percent of maximum heart rate, improved both sexual desire and overall sexual function in women dealing with medication-related libido problems.
The type of exercise matters. Aerobic activity tends to raise testosterone in premenopausal women, while resistance training alone doesn’t produce the same hormonal bump. Moderate to high intensity exercise (around 60 to 80 percent of your aerobic capacity) also increases cortisol in the short term, which at healthy, transient levels helps with alertness and energy. Prolonged endurance exercise boosts oxytocin as well, though short bursts of high-intensity work don’t seem to have the same effect.
The practical takeaway: a mix of cardio and strength training several times a week, at an intensity that gets your heart rate up and keeps it there, is the most effective exercise strategy for libido.
Check Your Testosterone
Testosterone drives libido in both men and women. In adult men, normal levels range from 193 to 824 ng/dL. In adult women, levels sit below 40 ng/dL but are still essential for sexual desire. When testosterone drops below your body’s functional range, sex drive often drops with it.
Low testosterone is more common than many people realize, particularly in men over 40 and in women after menopause. Symptoms beyond low libido include fatigue, reduced muscle mass, and a general sense of flatness or low motivation. If your desire has declined gradually over months or years and lifestyle changes aren’t helping, a simple blood test can check whether your levels are in range. Treatment options exist for both men and women, though the approach differs.
Fix Nutritional Gaps
Zinc plays a direct role in testosterone production. Research on elderly men found that increasing zinc intake nearly doubled their testosterone levels. Animal studies have also shown that zinc supplementation improves arousal and the ability to maintain erections. Zinc deficiency is surprisingly common, especially in people who don’t eat much red meat, shellfish, or legumes.
You don’t necessarily need a supplement. Oysters, beef, pumpkin seeds, chickpeas, and cashews are all high in zinc. But if your diet is limited or you suspect a deficiency, a basic multivitamin or standalone zinc supplement can fill the gap.
Supplements That Have Clinical Support
Most “libido boosters” on supplement shelves have little evidence behind them, but two stand out with actual clinical trial data.
Maca root, typically taken at 1.5 to 3 grams per day as a powder, has shown benefits in multiple trials. A 2008 study found that 3 grams daily improved sexual function and libido in men taking antidepressants. A separate trial of 45 women with antidepressant-related sexual problems found that the same dose taken for 12 weeks led to higher rates of symptom improvement compared to a placebo.
Tribulus terrestris showed statistically significant improvements in sexual desire, orgasmic function, and overall satisfaction in a 12-week randomized, double-blind trial of men with mild to moderate erectile difficulties. Participants took 1,500 mg daily of a standardized extract. The improvements were significant across multiple measures of sexual function compared to the placebo group.
Neither of these is a magic pill, but both have more evidence than most of what you’ll find at a supplement store.
Medications That Kill Libido
If your sex drive disappeared around the time you started a new medication, that’s probably not a coincidence. Antidepressants are the most common culprits. Every class of antidepressant can cause sexual side effects, but drugs that increase serotonin carry the highest risk. SSRIs like paroxetine, sertraline, fluoxetine, and escitalopram are well known for reducing desire, making it harder to become aroused, and interfering with orgasm. Among these, paroxetine carries the highest risk.
Other medications that commonly affect libido include blood pressure drugs, hormonal contraceptives, anti-anxiety medications, and certain antihistamines. If you suspect a medication is the problem, talk to your prescriber. Switching to a different drug in the same class, adjusting the dose, or adding a counteracting medication can often restore sexual function without sacrificing the original treatment benefit.
Alcohol: The Libido Paradox
A drink or two might make you feel more interested in sex by lowering inhibitions, but alcohol actively works against your body’s ability to respond. It dampens arousal by interfering with the brain signals needed to initiate physical response. It inhibits the part of your nervous system responsible for erections and lubrication. It widens blood vessels and drops blood pressure, reducing blood flow to the genitals. And because it’s a depressant, it dulls your sensitivity to touch, making it harder to get aroused even when your mind is willing.
Chronic heavy drinking compounds these problems over time by lowering testosterone and disrupting hormonal balance. If you’re trying to increase your sex drive, cutting back on alcohol is one of the simplest and most effective steps you can take.
Sleep, Stress, and the Basics
Cortisol, the body’s primary stress hormone, directly competes with sexual arousal. Chronic stress keeps cortisol elevated, which suppresses testosterone production and shifts your nervous system into a mode that’s incompatible with sexual response. Your body essentially prioritizes survival over reproduction.
Sleep deprivation has a similar effect. Studies have shown that restricting sleep to five hours per night for just one week can reduce testosterone levels by 10 to 15 percent in young men. That’s a meaningful drop, enough to noticeably affect desire and energy. Most adults need seven to nine hours for optimal hormonal function.
The unsexy truth is that the most powerful libido interventions are often the most boring: consistent sleep, regular exercise, managed stress, adequate nutrition, and moderate alcohol intake. These create the hormonal and neurological foundation that makes desire possible. Supplements and specific techniques work best on top of that foundation, not as a replacement for it.
