Experience slow aging with a 15-minute daily hormone reset habit!
The secret to living younger and healthier than your age lies in hormonal balance!

Professor Ahn Cheol-woo, Korea's leading hormone authority, has released a new book, "15-Minute Hormone Revolution," which overturns the stereotype that "aging is unavoidable."
Rather, based on scientific evidence that suggests that we can become healthier as we age, we present specific practices that can help us regain vitality in our lives with a 15-minute daily routine.
The author, an endocrinologist, finds the cause of 'accelerated aging' in hormonal imbalance.
It analyzes the causes of aging and adult diseases from the perspective of hormonal changes and explains that the balance of five key hormones, including melatonin, growth hormone, serotonin, oxytocin, and insulin, is the main factor determining the fate of health.


This book explains complex medical knowledge in easy-to-understand everyday language, and introduces 31 "15-minute daily hormone prescriptions" that anyone can follow, helping them put them into practice right away.
It helps you achieve a healthy life even in your busy daily life through sustainable routines such as a 15-minute morning walk, tea time meditation, climbing stairs, listening to music, and upside-down eating.
Good habits are more powerful than medicine or treatment.
"The 15-Minute Hormone Revolution" will be a new health book that teaches "how to manage life with hormones" not only to middle-aged people who want to delay aging, but also to everyone who wants to plan a healthy life from a young age.

Hormonal imbalance causes skin diseases
So why are so many people suffering from premature aging? Hormonal imbalance is a common cause of premature aging.
Type 2 diabetes, also known as acquired diabetes, occurs when the body's sensitivity to insulin, which regulates blood sugar levels, decreases.
If there is an abnormality in the secretion of cortisol, thyroid hormones, etc. along with insulin, hyperlipidemia may also occur.
This is also why the number of patients with diabetes and hyperlipidemia increases in middle age and older age when hormone secretion becomes difficult.
If hormonal imbalance is disrupted during accelerated aging, it will inevitably progress from minor illness to disease.

To prevent a minor illness from progressing into a disease, you must first recognize the abnormal signals your body is sending you.
If you feel tired easily, have trouble sleeping, experience mood swings, or your hair is thinning or your skin is saggy, making you look older, you should check to see if these are warning signals from your body.

Why the Dopamine You Need in Your 20s Is Still Necessary in Your 80s
As we age, our muscle strength, balance, nervous system, and reflexes decline.
To compensate for this, dopamine is absolutely necessary.
Dopamine is often known as the hormone of youth.
The dopamine-driven 'reward system' is involved in love, self-actualization, achievement, and sacrifice.
But dopamine really starts to shine much later.
Dopamine is involved in human movement and conscious movements of the limbs.
However, as we age, dopaminergic neurons are destroyed and signal transmission is interrupted, causing muscles to become stiff and limb movements to become slow.
If you do it wrong, your whole body could become paralyzed.
Parkinson's disease is a representative disease caused by dopamine deficiency.
It is the second most common degenerative disease after dementia.

Why does serotonin like to chat?
The chatter is powerful.
This applies to men as well as women.
Sharing your feelings and worries through small talk relieves stress and puts you at ease.
This emotional stability creates a positive feedback loop with the release of serotonin.
In fact, many studies have confirmed that anxiety and stress lower serotonin levels.
On the other hand, a sense of stability and peace of mind increase serotonin levels.
Chatting strengthens relationships with others, giving us a sense of belonging and connection, a sense of being socially connected.
These positive emotions are also associated with feelings of stability and happiness.
The joy felt during chatting is often expressed through laughter, which itself increases heart rate and lung capacity, producing effects similar to exercise.
These physical changes further activate serotonin secretion.

When estrogen disappears, cognitive abilities also decline.
It has long been known that estrogen affects cognitive abilities.
In 1988, a research team at McGill University in Canada conducted an experiment in which women whose estrogen levels had plummeted due to ovarian removal were divided into two groups and estrogen was injected periodically into only one side.
After three months, the cognitive abilities of the group that received estrogen injections and the group that did not were checked, and the group that received estrogen injections received significantly better scores in memory, cognitive speed, and reasoning ability.
A follow-up study conducted several years later found that the group that received estrogen injections showed little change in cognitive ability, while the group that did not showed a significant decline in cognitive ability.
In fact, estrogen increases cerebral blood flow, mediates hormones, promotes the formation of synapses in the brain, which are called 'information substations', and prevents brain cell death.
Therefore, menopause is not simply the cessation of menstruation, but an important time to look after a woman's physical and mental health.

Even though I exercise, I still gain weight?
The principle of dieting is simple.
You just need to have more calories going out than coming in.
Exercise is the best way to increase your calorie expenditure.
However, many patients who visit the clinic complain, “I gain weight even though I exercise.”
In fact, it is common to gain weight in the early stages of exercise.
There are three main reasons.
First, when muscle mass increases.
There is a difference between the density of muscle (about 1.1 g/cm³) and the density of fat (about 0.9 g/cm³).
Muscles are smaller in volume than fat but weigh more, so if you gain more muscle through exercise, you will gain weight.
But as time goes by, the weight gradually decreases.
Second, when the amount of water in the body increases.
When you exercise, your muscles store the energy they need as glycogen, but glycogen has the property of attracting water.
Water builds up in the muscles, causing temporary weight gain.
The last one is when you really gain weight.
If you have insulin resistance, exercising doesn't burn calories efficiently.
Additionally, if you have insulin resistance, your appetite may increase after exercise, leading to increased food intake.
In this case, insulin resistance must be corrected first.
