You probably don’t invest too much time considering your nipples– up until they require your attention. Possibly that’s when you’re exercising sans shirt and all of a sudden it’s like there’s a pair of headlights poking out from your sports bra. Or perhaps each time the temperature level drops below a specific degree, you seem like they might cut glass.
What Happens When You Stop Wearing a Bra?
But what really causes your nipples to get hard? Simply as no two individuals have the specific very same breast shape, no one’s nipples react the very same to different situations. Anatomically, there is a basic description for erect nipples.
The Science Behind Why You Get Erect Nipples
Anatomy time: “Underneath the nipple and areola (the location surrounding the nipple), there are tiny muscles that contract and pull on the skin and push the nipple out,” states Michelle Lee, M.D., a cosmetic surgeon based in Beverly Hills. In action to any sort of stimulation, “the sympathetic nerve system– part of the body’s neural circuitry that makes your heart race, skin get goosebumps, and palms sweat– sends signals to the nerves in those small little muscles that trigger them to contract,” she describes.
Naturally, that stimulation might be sexual. You probably currently understand your nipples are a delicate erogenous zone. Arousal– whether it’s from physical stimulation (e.g. touch) or mental stimulation (e.g. daydreaming about something hot and heavy)– sets off certain parts of your brain that “trigger those muscles in your nipples to become set up, similar to the effect those excited sensations can have on your genital areas,” states Heather Irobunda, M.D., an ob-gyn based in Queens, New York.
Simply like a clitoris or penis, nipples are made up of erectile tissue, a type of tissue that gets a ton of blood flow, says Dr. Irobunda. Studies show that nipple stimulation– or simply thinking about the nipples being stimulated– triggers this part of the brain.
If your nipples get hard as rocks when the Air conditioning is on high, that’s completely typical. The contracted skin then presses the nipple external,” she explains.
And sometimes, it’s not even about stimulation. Hormonal agents can likewise make your nipples hard when there’s no other apparent factor. “During your period or perhaps ovulation, modifications in your hormone levels– particularly estrogen– can trigger your nipples to end up being more sensitive or perhaps be more prone to become harder,” keeps in mind Dr. Irobunda.
Other hormone-related nipple changes start in pregnancy and continue through breastfeeding. “During pregnancy, the hormone progesterone causes the development of more milk lobules and duct systems,” describes Dr. Lee. And throughout the late stages of pregnancy, numerous other hormones trigger the areola to get larger and the nipple to get erect in preparation for breastfeeding, she adds. “During breastfeeding, mechanical stimulation of the nipple from the infant triggers the body to launch oxytocin; this hormone acts upon the milk glands to contract and push milk out to the baby,” says Dr. Lee.

What About Nipple Piercings?
If you’ve ever seen somebody with their nips pierced, their erect nipples are most likely pretty apparent– and you might have questioned whether those piercings change how your nipples get hard. The response? Yes and no.
The fact that positioning a large piercing at the base of the nipple will physically press it out, “having precious jewelry there triggers increased sensitivity due to the consistent stimulus to the nerves in the nipples,” discusses Dr. Irobunda. A nipple piercing does not indicate that your nipples will be hard 100 percent of the time, but it can definitely make them more noticeable and, since they’re more sensitive, they might end up being hard more quickly.
If You’re Concerned About Your Erect Nipples (or Lack Thereof).
Whatever your nipples do, there’s probably no factor to be worried. “Nipples come in all shapes and sizes, and depending on the size and position of the nipple, some nipples may appear to be never tough or constantly hard,” says Dr. Lee.
And, on a more serious note, “if the nipple all of a sudden becomes retracted or inverted; or if you notice nipple discharge, dimpling, discomfort, or swelling, it’s essential to see a medical professional and determine the reason,” says Dr. Lee.
What’s the Deal with Itchy Nipples?
And “if your nipples are not just tough however agonizing for an extended time period (versus during particular parts of your cycle), I would advise visiting your medical professional,” says Dr. Irobunda. “This might be a sign of a bigger health issue that needs to be dealt with,” she includes.
