When a young man wakes up, most of the time he’s not alone: His morning wood is usually there to greet him. An indicator of good male organ health, a hard male organ upon awakening can help get the day off to a good start. If one has the luxury of time to attend to it, morning wood can allow a man to engage in a little self-gratification. If there’s no time for play, it’s still a friendly reminder that this special friend is always ready for some a.m. fun.

But why do guys get morning wood so often? What is it that brings this pleasant state of affairs to be?

Yo, look at my nocturnal male organ tumescence!

While guys casually refer to a hard male organ upon rising as morning wood, there’s actually a technical term for it: nocturnal male organ tumescence, although that jaw-breaking phrase could be shortened to NMOT.  And, like a surprising number of things, scientists have actually studied this subject in some depth.

While men frequently just concentrate on the fact that they are waking up hard, the phrase nocturnal male organ tumescence refers to a number of firm states that typically occur between the time a guy hits the covers and when he yawningly tosses them off.  Unless a man has a firmness issue, he generally will pop three to five stiffies over the course of a good night’s sleep, the final one being the crowning morning glory with which he is so familiar.

It starts young.

While guys tend to associate morning wood with virile manliness of an adult sort, the fact is that NMOT starts early. Before adulthood. Before puberty. Before birth, even. Yes, male fetuses have been observed to be sporting a wake-up call even in the womb.

So…why?

The obvious answer to “Why does a guy get morning wood?” is: “Why not?” Firm rods happen throughout the day, so it seems obvious that they would occur during the night as well.

But why specifically do they occur at night and upon waking?  Despite the studies they’ve done, scientists don’t have a definitive answer just yet. But the best guess is that it is related to REM (rapid eye movement) sleep. REM periods are times during the night when sleep is especially deep and when there is a significant amount of dreaming. REM occurs in cycles, not necessarily lasting a long time.

During REM sleep, scientists theorize that a couple of things happen that may cause a hard male organ to develop. One is that special neurons (called noradrenergic cells, if one must know) get switched off during REM sleep. These are the neurons that have an inhibiting effect on the manhood. So, with these neuron cats away, the members get to play.

Another theory is that the body produces more nitric oxide during periods of REM sleep. Nitric oxide plays a big role in facilitating blood flow throughout the body – including in the member. That increased blood flow is essential for the achievement of tumescence.

There are also theories that NMOT has a practical aspect to it: It allows a man to sleep without having to get up to urinate. With the manhood in a tumescent state, urination is more difficult.

Whatever accounts for the nocturnal hard male organ, it’s a reminder for men to keep their tools in prime health. Applying a top-notch male organ health crème (health professionals recommend Man1 Man Oil) daily can help with this goal. Morning wood is all well and good, but when presenting that tool to a partner, it needs more than firmness. Smooth, appealing skin rather than dry flakiness is desirable, and a crème with a high-end emollient such as Shea butter is just the ticket for achieving this. It also doesn’t hurt to give one’s natural nitric oxide production a boost. Using a crème with L-arginine can assist in this area. L-arginine plays a role in the creation of that nitric oxide that morning wood has shown can be so valuable to a man.
