​Why Does Your Willy Shrink When It’s Cold?

According to several studies (yes, believe it or not some scientists have investigated this…) you can expect your penis to shrink by about 50 percent in length and 20 to 30 percent in girth when you are exposed to temperatures below 60F, regardless of how well-endowed you may be.

When the male body is cold, your blood vessels feeding the penis constrict, an effect which limits blood flow to your penis. The size of the penis, regardless of its state (flaccid or erect) overwhelmingly depends on blood flow and volume. An erection is after all, an engorging of the penis thanks to your body rapidly pumping blood into it.

Interestingly, there’s an evolutionary benefit to shrinkage when your body is exposed to the cold. The male body has evolved to preserve heat and energy. So, in the cold, it funnels its resources into maintaining blood flow to your brain and the middle of your body, where your vital organs are.

To accomplish that, your body must reduce blood flow to your appendages—such as your fingers, toes, and of course, your penis. At the same time, your testicles retract and rise closer to the rest of your body so they can also stay as warm as possible.

The whole process is yet another evidential fact that blood flow is a fundamental factor when it comes down to penis size, particularly during erection. The optimization of blood flow depends on several factors, such as age, overall cardiovascular health, visceral fat, and even your mood or stress.

That is why it is very important for you to exercise and maintain an appropriate diet. Taking supplements on a regular basis, can also greatly help you with that objective, as your body requires the appropriate vitamins, and nutrients to optimize the erection process.

The good news is that there are many supplements available in the market that have been developed with the specific objective of supporting increased blood flow. Black Snake GoldTM, by Vigor Labs, is one of the leading supplements for blood flow support. It is formulated with naturally sourced potent ingredients that have been used for hundreds of years as a sexual enhancer*. You can learn more about Black Snake GoldTM on Vigor Labs website at
