Good morning wood is something you want to see every single day when you wake up.
And if you’re not seeing this wood three to five times Every Night, starting around 2 am and running all the way until daybreak, you need to fix the situation.
Because morning wood is a benchmark of reproductive health. A signal that your hormones, your vascular system and your brain are all functioning properly.
Good Morning Wood And REM Sleep
When you’re in a rapid eye movement (REM) sleep cycle, your body shuts down the production of norepinephrine, a neurotransmitter that constricts the blood vessels leading to your penis.
It does this so it can begin the repair and rebuilding process of your pipes.
So if you miss out on this REM sleep cycle, or fail to stay in it long enough, norepinephrine will stay elevated all night long, which will impact your wood the following morning.
This happens because norepinephrine constricts blood flow, which prevents the vasodilation of your corpus cavernosa, and if you can’t dilate the cavernosa, you can’t get an erection.
Morning, noon or night!
This lack of nighttime blood flow will also cause other problems, because the rush of blood into your penis at night oxygenates and repairs vascular smooth muscle cells while you sleep.
This process is so hard wired into humans, it even happens to women in a process called Nocturnal Clitoral Tumescence (clitorial erections) when they’re in REM sleep.
Ideally, you should spend about 25 percent of your sleep in REM, and if your morning wood is lacking, this is the very first thing you should work on.
35 percent of Americans get less than seven hours of sleep per night, meaning most of these people are falling well short of their REM sleep requirements.
And this lack of REM sleep not only impacts erections, but it also increases your risk of developing heart disease, diabetes, depression, insulin resistance and obesity.
It also increases your risk of premature death from all causes.
