Yes, masturbation is a normal, healthy sexual activity. It carries no known physical harm, and research points to several measurable benefits for mood, stress, sleep, and even long-term health outcomes like prostate cancer risk. The old warnings about it causing blindness, hair loss, or physical weakness have no basis in science.
What Happens in Your Body
When you masturbate to orgasm, your brain releases a cascade of chemicals tied to its pleasure and reward system. Dopamine drives the feeling of satisfaction. Oxytocin, sometimes called the “love hormone,” promotes relaxation and social bonding. Serotonin helps regulate mood and creates a sense of optimism. Endorphins, the same chemicals responsible for a runner’s high, reduce pain perception and produce a wave of wellbeing. Prolactin, released after orgasm, supports stress management and has a neuroprotective effect, helping shield brain cells from stress-related damage.
This hormone cocktail is why many people feel calmer, happier, and sleepier after masturbating. It’s the same basic chemical response your body produces during partnered sex.
Stress, Sleep, and Mood
The release of oxytocin and serotonin during orgasm helps lower stress and anxiety. Prolactin, which rises sharply after climax, promotes drowsiness, which is one reason masturbation before bed can make it easier to fall asleep. For people dealing with everyday tension or restless nights, it functions as a low-risk, drug-free way to wind down.
Masturbation also tends to improve mood more broadly. The combination of dopamine, endorphins, and oxytocin creates a short-term but genuine lift in emotional state. This isn’t a substitute for treating clinical depression or anxiety, but as a regular part of life, it contributes to emotional regulation in the same way exercise or social connection does.
Prostate Cancer Risk in Men
One of the more striking findings comes from a large, long-running study highlighted by Harvard Health. Men who ejaculated 21 or more times per month had a 31% lower risk of prostate cancer compared to men who ejaculated four to seven times per month. A separate analysis found that men averaging roughly five to seven ejaculations per week were 36% less likely to be diagnosed with prostate cancer before age 70 than men who ejaculated fewer than two to three times per week.
The mechanism isn’t fully understood, but one theory is that frequent ejaculation helps flush out potentially harmful substances from the prostate. These findings apply to ejaculation from any source, including masturbation.
Period Pain Relief
Endorphins released during orgasm act as natural painkillers, which can provide temporary relief from menstrual cramps. The increased blood flow to the pelvic area and the rhythmic muscle contractions of orgasm may also help ease the tension that contributes to cramping. It won’t replace medication for severe pain, but many people find it offers real, if short-lived, comfort during their period.
Immune Function
Research from the Cleveland Clinic notes that people who engage in sexual activity one to two times per week have higher levels of immunoglobulin A (IgA) in their saliva, an antibody that helps fight off illness. The same source notes that masturbation can produce similar results to partnered sex when it comes to these benefits.
Body Confidence and Sexual Satisfaction
Masturbation promotes self-exploration in a practical sense: you learn what feels good, what doesn’t, and how your body responds to different kinds of touch. Research from Hospital Clínic de Barcelona found that people who masturbate tend to report higher self-esteem, greater self-confidence, and a more positive body image. This self-knowledge translates to partnered sex too, making it easier to communicate preferences and feel comfortable with a partner.
Common Myths That Aren’t True
Masturbation does not cause blindness, acne, hair loss, infertility, or permanent changes to testosterone levels. These claims have been circulating for centuries, often rooted in religious or moral frameworks rather than biology. On extremely rare occasions, vigorous physical activity of any kind (including masturbation) can pop a small blood vessel, potentially even in the eye, but this requires excessive force and is not a realistic concern during normal self-stimulation.
There’s also no evidence that masturbation shrinks genitals, weakens muscles, or depletes your body of nutrients in any meaningful way. Semen contains small amounts of zinc, protein, and other substances, but the quantities lost during ejaculation are trivial and easily replaced through normal eating.
When It Could Become a Problem
Masturbation becomes unhealthy only in specific circumstances. If it’s compulsive to the point where it interferes with work, relationships, or daily responsibilities, that pattern may signal an underlying issue with impulse control or emotional coping rather than a problem with masturbation itself. Physical irritation or soreness from excessive friction is possible but resolves on its own with a break. Using a lubricant helps prevent this.
Guilt and shame are the most common negative experiences people report, and these are almost always cultural or religious in origin rather than a response to any physical harm. If masturbation consistently leaves you feeling distressed, working through those feelings with a therapist who specializes in sexual health can help separate learned shame from genuine concern.
For the vast majority of people, masturbation at whatever frequency feels natural is a safe, beneficial part of a healthy life.
