Special prescription from a urologist
“Running is better than medicine!”

If you don't take care of it consistently, your body will start to creak here and there as you age.
Among these, problems with sexual function mean that a red light has been turned on for overall health.
Since the penile blood vessels, which are tiny blood vessels, are the first to be attacked by adult diseases, sexual function can be said to be a mirror that reflects the state of health.
The author, a urologist, recommends running instead of medication as a way to boost male sexual function and restore health and vitality.
Diabetes is linked to high blood pressure, high cholesterol, and gout, and together with obesity, it damages the blood vessels, nerves, and hormones in our bodies.
Neither one is independent.
So, sexual function cannot be easily improved with just one or two measures.
It is only possible to maintain sexual function by understanding and simultaneously managing the interactions of factors that affect it.
Running is the solution to this.
The author, who prescribes running to patients requesting Viagra prescriptions, explains in this book that regular running is actually effective in preventing the negative effects of chronic disease and stress, as well as the blood vessels and nerves that make up sexual function.
Not only that, it also gives you specific instructions on when, how, how hard, and how long to run.
It also provides useful information to readers who do not have running knowledge by suggesting what to do if an injury or pain occurs while running, and stimulates the desire to go out and run right away.

It is also important to keep in mind that sexual function can be affected by hidden medical conditions that we are unaware of.
Penile blood vessels are narrower in diameter than heart blood vessels, so if there is a disease in the blood vessels, erectile dysfunction occurs before heart disease.
In fact, many studies have shown that people with erectile dysfunction who continue to live their lives without making any changes are more likely to develop cardiovascular disease.
Diabetes and hyperlipidemia also cause erectile dysfunction, and if left untreated for a long time, they can damage not only the penis but also the blood vessels in the brain.
When a cerebral blood vessel is damaged, it doesn't just end with erectile dysfunction; it can also lead to life-or-death issues.
So, if you have erectile dysfunction, you should be aware that there may be a serious, life-threatening illness lurking behind it.
Erectile dysfunction should not be dismissed as just a symptom, but rather as a signal of a general threat to overall health.

Running definitely restores sexual function.
It was published through scientific research and was included in textbooks, gaining credibility.
And a urologist in his forties, whose life was a mess, even tried it himself and experienced its effectiveness.
This means that the effects of running are likely a universal fact, not a product of intuitive conjecture, and that simply putting it into practice increases the likelihood of success.
The input is running, but the output is a powerful sexual function.
A vibrant life is something that is given as a bonus.

In the modern life, which is damp with constant tension and anxiety, there is little room for the parasympathetic nervous system.
Let's think about what happens when the parasympathetic nervous system takes control of our body.
When the parasympathetic nervous system is activated, it sends blood to the organs and promotes digestion.
Relax your muscles, release tension and let your body rest.
It lowers your heart rate, calms you down, and allows you to sleep, allowing your body to recover from the hard work it has done during the day.
And the parasympathetic nerves dilate the blood vessels of the penis, causing an erection.
We have just come to understand an important principle.
Why do modern people always suffer from indigestion, have stiff necks, have trouble falling asleep despite being tired, and why do they cry because of weakened sexual function despite being young and not yet old?

Exercise-induced improvement and prevention of adult diseases also occur in areas unrelated to insulin resistance.
When muscles are used frequently during exercise, various metabolites are created that help dilate blood vessels, and substances called nitric oxide and prostacyclin are secreted that help blood vessels relax smoothly.
As your muscles grow, it's only natural that your body releases more substances that help dilate blood vessels.
This is because when you build muscle through intense exercise, more blood needs to flow to maintain and move it.
That's why we often see bulging veins on the arms of people who do a lot of muscle training.
When blood pressure rises, our bodies relax blood vessels to maintain a constant pressure. The ability to dilate blood vessels developed through exercise also leads to flexibility, which improves and prevents high blood pressure.
The vascular system developed for muscles also has a positive effect on blood pressure regulation.

Running's ability to lower blood pressure and heart rate, which in turn reduces palpitations, can be a great way to reduce unnecessary anxiety.
The tendency to feel anxious due to a high heart rate can be eliminated through exercise.
Regular running fosters a positive awareness that heart palpitations aren't always associated with anxiety.
As you experience the positive movement and post-exercise refreshment and cool, refreshing feeling that running provides, along with the excitement, you'll be able to break the cycle of misconceptions that excitement is always associated with anxiety.

They say it's a world where it's difficult to survive and adapt day by day.
I wonder how many men actually maintain their sexual function until old age.
The reason why people don't panic too much about early decline in sexual function in middle age is probably because many middle-aged men do.
In this context, the suggestion that you should indulge in exercise to improve your sexual function is somewhat unconvincing.
It's a world where people reach for a cigarette rather than exercise.
It seems better to pour a glass of soju into my mouth and get some sleep.
But that's not wise.
Because everything is connected.
A man must realize that when he turns away from his function as a man, other things fall apart.
As you've read so far, you've probably realized how sensitive sexual function is to the environment and disease.
Sexual function is like a mirror reflecting the health of the body.
Ignoring this is no different from ignoring health itself.
