Fall belongs to Yin

What the Shift from Yang to Yin Means for Your Body

Yang has been in the lead all summer.

It stayed light until ten o'clock at night, the warmth was outside, and you were constantly on the go. Everything was focused on the outside world.

On September 23, the two will be in balance for the last time this year: twelve hours of daylight, twelve hours of darkness. Starting the next day, the night will be longer than the day, and it will remain that way until winter.

What decreases outside can increase inside.

What's outside LESS will be,
may be used indoors MORE will be.

Starting now Yin leads the way. And it leads in a different direction.

☯️ What Yin and Yang Really Are

Most people know Yin and Yang as light and dark, as feminine and masculine, as the black-and-white symbol on some T-shirt. And almost everyone thinks of them as two forces in conflict with one another.

That's exactly what they're not.

Think about day and night for a moment. There is no “day force” or “night force” that take turns prevailing. There is only one Earth that rotates. Day and night are not two separate things, but two names for the same movement, depending on where you happen to be standing.

It's the same with yin and yang. They are not opposites, but rather two sides of a single process.

That's why there is no such thing as pure Yin or pure Yang. It always depends on what you're comparing it to.

An autumn day feels cool when you think of July. And that same day feels mild when you think of January.

One day, two answers. Both are correct.

🫀 What these two are in your body

In Chinese medicine These have become two terms that describe everything going on inside you.

Yang is everything that does. It warms, it moves, it drives you forward, and it protects you from the outside world. Yang is the force that gets you out of bed in the morning, helps you digest your food, and defends you against the cold.

Yin is everything you're made of. It nourishes, it cools, it moisturizes, and it rebuilds. Yin is the blood; it is the bodily fluids and saliva, the moisture in the skin and mucous membranes, and the substance in bones and tissues. And Yin is also sleep, during which all of this is restored.

One is the function, the other is the material.

🕯️ The Candle

There is an old picture, which makes the connection between the two clear in an instant.

Imagine a candle. The flame is the Yang, because it shines, it gives off heat, it moves, and you can see it. The wax is the Yin, because it is still, it is cool, and it seems to do nothing.

But the flame feeds on the wax. It burns it as it burns.

And that contains everything that now lies before you. A flame that burns at a constant height will eventually use up all its wax. Then it becomes restless, it flickers, it grows smaller, and finally it goes out.

Summer was the time when the flame burned brightly. It got late, it was hot, you were sweating, and you were out and about a lot. All of that took its toll.

Now begins the time when wax is poured. Fall marks the beginning of this period, and winter brings it to a close. Winter is the deepest Yin of the entire year.

So autumn isn't tranquility itself. It's the path to it.

🌙 The Evening of the Year

There is a second thought, which is what makes this medicine so practical: The same movement is repeated at every level.

Throughout the year, spring begins, summer unfolds, fall gathers, and winter preserves.

And in a single day, it looks exactly the same. The morning is spring, noon is summer, the evening is fall, and the night is winter.

So you experience a little year every day.

That’s exactly why it’s so easy to picture fall. It’s the evening of the year. And no one would think of starting to build a house at nine o’clock at night. You tidy up, have something warm to eat, and dim the lights.

Fall does exactly the same thing. Only it takes weeks instead of hours.

🌀 Yin did not come into being today

Here's the idea:, which distinguishes the Chinese perspective from our usual way of thinking.

We tend to think of change as a break: something ends, and then something else begins. From the Chinese perspective, nothing becomes its opposite by ceasing to exist. It becomes its opposite by reaching its peak.

The Yin of this fall came into being on the longest day of the year, in the middle of June, when the Yang was at its peak and no one was thinking about it. It began to grow at that very moment.

That is why the Taiji symbol features a dark dot in the light field and a light dot in the dark field. This is not merely a decorative element, but the very essence of its message: Within the greatest abundance lies the beginning of emptiness, and within the deepest darkness lies the beginning of light.

So September 23 isn't the day something begins. It's the day when you can finally see what's been going on for the past three months.

🔥 Yang doesn't disappear—it just moves on

Corrected here Chinese medicine corrects a misconception that almost every self-help book repeats.

In the fall, Yang does not diminish. It moves from the surface to the depths.

In the summer, your body heat was on the outside. Your skin was warm, your pores were open, you were sweating slightly, and your body was releasing heat outward. Now that heat is retreating inward, toward your organs.

This leads to two conclusions that seem contradictory at first glance.

Your hands and feet get cold earlier, even though it’s still mild outside. And at the same time, your digestive power grows stronger inside. That’s exactly why you can handle heartier meals in winter than in August. There’s more fire burning inside, not less.

The second point concerns your protection. As long as the energy moves inward, the outer layer is less well-protected. Chinese medicine refers to this protective layer as the Wei-Qi, the body's defenses. And that's why the first infections tend to occur during these very weeks. Not because it's cold, but because the body is undergoing changes right now.

🌾 How Yin Comes into Being

Yin can be It cannot be talked into existence, nor can it be enforced through discipline. It arises from three things: sleep, rest, and nourishing, moist, warm food.

That is why the ancient texts talk so much about sleep in the fall and winter. Not because sleep sounds healthy, but because it is the most important building block of this season. At night, it is Yin’s turn, and at night, the body builds itself up.

And now, a distinction that is often overlooked. Fall and winter are not the same Yin. The ancient texts speak of the young Yin of fall and the great Yin of winter. The young Yin is still in motion and is still gathering. The great Yin merely preserves.

That's why October feels different from January. And that's why it would be a mistake to scale back as much as we do in December at this point. Right now, we're still making progress.

💫 How you can tell by your own behavior

All of that would remain just a theory, if you didn't feel it. But that's exactly the point: You've been feeling it all along; you've just been calling it something else.

You'll get tired sooner. It's dark by seven in the evening, and by 9:30 you're exhausted, even though you haven't worked any harder than you did in July.

You want to spend less time around people. The plans for Friday—which you would have been looking forward to back in June—suddenly feel like a hassle.

You'll become quieter and more thoughtful. On gray days, you find yourself turning inward, and old thoughts resurface—thoughts you hadn't noticed during the summer.

You want to eat something hot. You're not in the mood for yesterday's salad anymore, but you are in the mood for the soup.

That's not a mood swing, and it's not a letup either. That's the season within you.

💡 But let's not let that happen

And here That's when the real problem begins.

Your schedule in October looks just like it does in June. At 10 p.m., your apartment is as bright as it is in the afternoon; the screen shines right in your face even though it’s long since been night outside; and in the morning, you leave the house in the dark, get in your car, and head to the office.

Remember what "Yang" means: It is light, it is warmth, and it is activity.

So you’re bringing Yang into the very hours that belong to Yin. Your body then does what it’s supposed to do. It stays awake, keeps your activity levels up, and pushes the night further back. And in the morning, when the real Yang begins outside, you don’t even notice it.

That's why you're tired in the fall but still can't seem to relax. It's not the darkness that's getting to you, but the fact that you light it up in the evening and take it with you to the office in the morning.

We turned every evening into a second lunch.

🌿 Four Steps That Work with Yin

You have to Don't turn your life upside down. All you have to do is stop working against it in four areas.

1. Get your Yang in the morning

Go outside for ten minutes during the first hour after you wake up. This could be stepping out onto the balcony, having coffee on the front porch, or taking a short walk.

Your internal clock resets every day, and it responds to only one signal: bright light. Even on a cloudy fall day, it’s many times brighter outside than in any room. If you set it in the morning, you’ll be rewarded with the evening.

2. Take the yang out of the evening

Starting at dinnertime, make it darker around you. Leave the ceiling light off and use a small lamp instead, and put your screen away before you go to bed.

That way, you let the evening be an evening again. When you dim the lights, you don't get artificially tired. You just stop forcing yourself to stay awake.

3. Give in to the urge to retreat

If you're tired at 9:30, go to sleep. If you'd rather spend the weekend at home, go ahead and do that—and it's better to cancel an appointment than to drag yourself there.

What looks like a lack of drive here is actually the process of replenishing wax. If you don't gather your strength in the fall, you'll have nothing to draw on in the winter.

4. Eat warm, and eat moist

A warm porridge in the morning, soup in the evening, a steamed apple instead of a raw one. It's not the amount that matters, but the temperature and the consistency.

Your body heat is currently retreating inward, and every cold breakfast drains energy that is needed there. Soft-cooked, moist foods also provide exactly what your Yin is made of.

🌬️ And when you're feeling hyper in the afternoon And if you still don't want to get tired, breathe in for five seconds and breathe out for five seconds, and keep doing this for five minutes.

Inhaling is Yang; exhaling is Yin. When both are of equal length, they balance each other out, and you find peace without becoming tired.

▶️ Instructions for Participating — You don't have to count along.

🍂 In closing

Nature It doesn't jump. It shifts by a few minutes every day, and the next day it shifts a little further.

You can do it that way, too.

Your tiredness isn't a mistake. It's proof that your body has long since kept up with the pace, even though your calendar is still stuck in summer.

Summer belonged to Yang. From now on, Yin takes the lead.

Let it take the lead. Because what diminishes on the outside can increase on the inside.
