The idea that sex can help with PMS might sound too good to be true, but the science is surprisingly supportive. Orgasms trigger a cascade of neurochemical changes that directly target some of the most common premenstrual complaints, from cramps and headaches to mood swings and tension. Whether with a partner or solo, intimacy during your cycle is not just safe; it may be one of the most effective natural remedies available. Here is what the research says about sex during period benefits and how to make the most of it.
Does Sex Help Period Cramps? The Endorphin Effect
Menstrual cramps are caused by uterine contractions triggered by prostaglandins, hormone-like compounds that increase during your period. Higher prostaglandin levels mean stronger contractions and more pain. Orgasm counters this in two key ways. First, the brain releases a surge of endorphins, neurotransmitters that bind to opioid receptors and block pain signals in much the same way pharmaceutical painkillers do. Second, the rhythmic uterine contractions during orgasm help expel menstrual blood and prostaglandins more efficiently, which can reduce cramping intensity.
A landmark study by Whipple and Komisaruk published in the journal Pain found that vaginal self-stimulation to the point of orgasm increased pain tolerance thresholds by 74.6% and pain detection thresholds by 106.7% in women. These were not minor shifts; they represent a substantial, measurable analgesic effect that rivals some medications. For consistent cramp support alongside these natural benefits, Glow's Period SOS Cream can be massaged into the lower abdomen to soothe discomfort topically.
Intimacy and PMS Mood Symptoms
PMS does not just cause physical symptoms. Irritability, anxiety, low mood, and emotional sensitivity are driven by fluctuating oestrogen and progesterone levels in the days before your period. Sexual activity and intimacy address these symptoms through several hormonal pathways.
Oxytocin: The Bonding Hormone
Physical touch, skin-to-skin contact, and orgasm all trigger the release of oxytocin. Often called the "love hormone," oxytocin promotes feelings of trust, relaxation, and emotional connection. A study on oxytocin and pain tolerance found that higher oxytocin levels are associated with increased pain tolerance, suggesting that even cuddling and non-sexual intimacy can offer some relief during PMS.
Dopamine and Serotonin: Mood Stabilisers
Orgasm also triggers a release of dopamine, the brain's reward chemical, and serotonin, which regulates mood and emotional stability. Both of these neurotransmitters tend to dip premenstrually, contributing to the low mood and irritability that characterise PMS. Sexual activity offers a natural, immediate boost to both, helping to counterbalance the hormonal dip that your cycle creates.
Can Sex Help With Menstrual Headaches and Migraines?
Hormonal headaches and migraines are common PMS complaints, often triggered by the oestrogen drop before menstruation. Research published in Cephalalgia found that among people who engaged in sexual activity during a migraine, 60% of migraine sufferers reported improvement, with most describing moderate to complete relief. For cluster headaches, roughly a third reported that sex improved their pain. The mechanism is likely the same endorphin-driven analgesia that helps with cramps.
Stress and Sleep: The Overlooked Benefits
Cortisol levels can spike premenstrually, amplifying anxiety and disrupting sleep. The combination of oxytocin, endorphins, and physical exertion during sex promotes a state of deep relaxation that can lower cortisol and improve sleep quality. Better sleep in turn reduces PMS severity, as sleep deprivation worsens pain perception, mood instability, and cravings. If sleep is a persistent challenge, Glow's Super Rich Magnesium Body Lotion can complement your wind-down routine by supporting relaxation through topical magnesium.
Practical Tips for Comfortable Intimacy During Your Period
Period sex is safe and poses no health risks, but a little preparation goes a long way:
-
Place a dark towel down to manage any mess and reduce self-consciousness
-
Use protection, as pregnancy is still possible and STI risk remains the same during menstruation
-
Remove any internal menstrual products (tampons, cups) before penetrative sex
-
Positions that minimise deep penetration, such as spooning, can be more comfortable if you are experiencing cramps
-
Solo orgasms count too; masturbation delivers the same endorphin and oxytocin benefits without any of the logistical considerations
If dryness is a concern (some women experience it despite menstrual flow), Glow's Intimate Hydrator provides gentle, hormone-safe moisture support.

Frequently Asked Questions
Q1: Can sex actually reduce period cramps?
Yes. Orgasm releases endorphins that block pain signals and triggers uterine contractions that help clear prostaglandins. Research shows orgasm can increase pain tolerance by nearly 75%.
Q2: Does it matter whether you orgasm from sex or masturbation?
No. The endorphin and oxytocin release happens regardless of how the orgasm is achieved. Solo orgasms deliver the same pain-relieving and mood-boosting benefits as partnered sex.
Is it safe to have sex during your period?
Yes. There are no health risks associated with period sex. Use protection to prevent pregnancy and STI transmission, and remove any internal menstrual products beforehand.
Q3: Can sex shorten your period?
It is possible. The uterine contractions during orgasm can help shed the lining more quickly, potentially shortening menstrual flow. However, there are no clinical trials confirming this effect.
Q4: What if I experience pain during sex around my period?
Stop if you experience pain. Painful sex (dyspareunia) around your period can sometimes indicate conditions like endometriosis or fibroids. If it persists, consult your healthcare provider.
