  • Now that we got the one obligatory joke out of the way, we can get to the hard facts of nocturnal penile tumescence, otherwise known as "morning wood".

  • The mind and body go through stages of sleep, from non-REM stages, which gradually become deep sleep finally followed by REM or "Rapid Eye Movement" sleep which is actually fairly shallow sleep.

  • As you enter REM sleep, not only do dreams occur, but a few physiological changes take place as well.

  • Namely, your brain begins to shut off some neurotransmitters in an effort to regulate your body, and in some cases stop you from acting out your dreams.

    也就是說,你的大腦開始關閉一些神經遞質,以努力調節你的身體,在某些情況下,你會阻止你的夢想行動。

  • One of these neurotranmitters, norepinephrine, happens to be involved with the control of erections.

    這些神經遞質之一,去甲腎上腺素,恰好與勃起的控制有關。

  • Specifically it causes vasoconstriction of penis blood vessels, actively preventing an erection.

  • It is like a stop sign for blood flow. But as you enter REM sleep, norepinephrine decreases and testosterone related actions are now able to take place.

    它就像一個血流的停止信號。 但當你進入REM睡眠時,去甲腎上腺素減少,睪丸激素相關的動作就能夠發生了。

    這就會導致血管擴張,或增加血管的血流量,最終導致勃起。

    為什麼這很重要?

  • Well, similar to muscle and other tissue, at night this extra blood increases oxygenation, serving as a system of repair and helping to maintain functionality.

  • Well, we often wake up just out of REM sleep, and as a result see the remnants of this sleep stage.

    好吧,我們經常是剛從REM睡眠中醒來,結果就看到了這個睡眠階段的遺蹟。
