Sex drive is regulated by a mix of hormones, brain chemistry, stress levels, and lifestyle habits, which means there are several practical ways to raise it. The most effective approaches target the root cause of the dip, whether that’s poor sleep, chronic stress, low physical activity, or a medication side effect. Here’s what actually works and why.
Why Sex Drive Drops in the First Place
Sexual desire starts in the brain. A region called the ventral tegmental area releases dopamine into the brain’s reward system, which triggers the motivation to seek out sexual activity. Several other chemical messengers, including serotonin, noradrenaline, and oxytocin, either amplify or dampen that signal. When something disrupts this system, desire fades.
Testosterone plays a central role in sex drive for both men and women. Studies on men treated with drugs that block testosterone receptors show a five- to six-fold increased risk of reduced libido. In women, shifts in estrogen and testosterone during menopause, postpartum recovery, or hormonal contraceptive use can have a similar effect. Prolactin, another hormone, can suppress desire when levels run too high, partly by interfering with dopamine activity in the brain area most responsible for sexual motivation.
Beyond hormones, chronic stress activates the body’s fight-or-flight system and floods the brain with cortisol. That cortisol redirects the brain’s attention toward threats and away from reward-seeking behaviors like sex. A persistently disrupted stress response can dysregulate the entire hormonal chain that governs sexual function.
Exercise More, Especially at Higher Volumes
Physical activity is one of the most reliable ways to boost sex drive. Research examining the relationship between exercise volume and sexual function found that people in the lowest exercise group had significantly lower sex drive compared to every higher exercise group. The effect was strong and consistent. Higher exercise volumes also improved desire for partnered sexual activity specifically.
You don’t need to become an elite athlete. The key finding is that moving from very little exercise to a moderate amount produces the biggest jump. A combination of strength training and cardio works well because resistance exercise supports healthy testosterone levels in both sexes, while cardio improves blood flow and reduces stress hormones. Three to four sessions per week of 30 to 45 minutes is a reasonable target. Overtraining, on the other hand, can suppress sex drive, so more isn’t always better.
Prioritize Sleep Quality
Sleep deprivation hits testosterone levels hard, but the effect depends on severity. A meta-analysis found that total sleep deprivation of 24 hours or more significantly reduced testosterone in men. Going 40 to 48 hours without sleep dropped levels even further. Partial sleep loss on a single night, like getting five hours instead of eight, didn’t produce a measurable dip in the short term.
The practical takeaway: occasional short nights probably won’t tank your libido, but a pattern of severely restricted sleep will. Chronic sleep debt accumulates. If you’re consistently sleeping fewer than six hours, your hormonal environment is working against your sex drive. Improving sleep hygiene, keeping a consistent wake time, limiting screens before bed, and keeping the room cool, is one of the lowest-effort, highest-impact changes you can make.
Manage Chronic Stress
Cortisol doesn’t just compete with sex hormones for the body’s attention. It also reshapes how the brain processes emotional and physical cues. Under chronic stress, the brain becomes biased toward threat detection and less responsive to pleasurable stimuli, including sexual ones. This isn’t a willpower problem. It’s a neurochemical shift.
Effective stress reduction looks different for everyone, but the interventions with the strongest evidence include regular aerobic exercise (which does double duty here), mindfulness meditation, and cognitive behavioral techniques. Even simple changes like reducing work hours, spending time outdoors, or scheduling downtime can lower baseline cortisol over weeks. The goal isn’t eliminating stress entirely. It’s preventing the chronic, unrelenting kind that keeps your body locked in survival mode.
Check Your Medications
If your sex drive dropped around the time you started a new medication, that’s worth investigating. SSRIs, the most commonly prescribed class of antidepressants, are a frequent culprit. A realistic estimate is that 30 to 50 percent of people taking SSRIs experience some form of sexual dysfunction, ranging from reduced desire to difficulty with arousal or orgasm. Some individual SSRIs may affect as many as 70 percent of users.
Other medications that commonly suppress libido include hormonal contraceptives, blood pressure drugs, anti-seizure medications, and opioids. If you suspect a medication is involved, talk to your prescriber about alternatives. For antidepressants specifically, switching to a different class or adjusting the dose can sometimes restore sexual function without sacrificing mental health benefits. Don’t stop any medication on your own.
Herbal Supplements With Some Evidence
Most supplements marketed for libido have weak or nonexistent evidence behind them, but maca root is a notable exception. In one study, men who consumed 1.5 or 3 grams of maca daily reported increased libido compared to a placebo group. Another trial found that 2.4 grams daily for 12 weeks improved sexual well-being in men with erectile difficulties. There’s also preliminary evidence that maca may help with sexual side effects from antidepressants in postmenopausal women.
Typical study doses range from 3 to 3.5 grams per day, roughly one teaspoon of maca powder. It’s generally well-tolerated, though the effects are modest. Maca is not a replacement for addressing underlying causes like stress, poor sleep, or hormonal imbalances. Think of it as a potential complement to the bigger lifestyle changes, not a standalone fix.
Prescription Options for Persistent Low Desire
When low sex drive persists for months, causes significant distress, and doesn’t respond to lifestyle changes, it may qualify as a clinical condition. The diagnostic threshold requires both a persistent absence of sexual desire and meaningful personal distress about it. This isn’t about comparing yourself to some external standard. It’s about whether the change bothers you.
For premenopausal women, two FDA-approved medications exist. Flibanserin is a daily pill that works on serotonin and dopamine pathways in the brain. Bremelanotide is a self-administered injection taken about 45 minutes before a sexual encounter. Both have shown statistically significant effects on desire, but the real-world improvements are modest compared to placebo. Flibanserin carries side effects including sleepiness, fainting, and dangerous interactions with alcohol. For men, testosterone replacement therapy is an option when blood tests confirm low levels, though it comes with its own risk profile that requires medical monitoring.
Relationship and Psychological Factors
Sex drive doesn’t exist in a vacuum. Relationship satisfaction, emotional safety, unresolved conflict, and communication patterns all feed directly into desire. For people in long-term relationships, a dip in sex drive often reflects emotional distance rather than a biological problem. Addressing resentment, improving communication about needs, or simply spending more non-sexual quality time together can reignite desire in ways no supplement or medication can.
Body image, past trauma, and mental health conditions like depression and anxiety also shape libido. Depression in particular creates a double bind: the condition itself suppresses desire, and the most common treatments for it can do the same. Working with a therapist who specializes in sexual health can help untangle these layers when the cause isn’t straightforwardly physical.
