When I was younger, I thought, "What's the big deal about a little stress?"

But now that I'm approaching my 50s, I realize how frightening that statement is.

In the past, I could work all night and be fine the next day, but these days, just a few days of stress keeps me up at night, makes my stomach feel bloated, and I find myself getting irritated for no reason.

People often say, "Stress kills people." This isn't just a saying; the culprit is a hormone called cortisol.

Cortisol is actually a good hormone that protects our bodies.

When dangerous situations arise, it raises blood sugar to create energy, maintains blood pressure, and helps the body cope with crises.

The problem occurs when this hormone remains elevated for not just a day or two, but for months or even years.

For example, if a business isn't doing well, or if there are ongoing family issues, or if financial worries never cease, the body continues to misinterpret that as "danger."

As a result, cortisol keeps being secreted. And from that point on, the body starts to deteriorate and behave strangely.

The first thing that happens is trouble sleeping. Even when I'm tired, my mind keeps racing, and I wake up repeatedly in the early morning.

Then, I end up drinking more coffee to cope with the fatigue at work, and the cycle of not sleeping at night repeats itself.

My stomach also starts to bulge. Interestingly, while my arms and legs remain the same, many people notice just their stomachs sticking out.

It is known that high cortisol levels lead to the accumulation of abdominal fat. While it's true that "getting older leads to a bigger belly," stress is also a significant factor.

As this continues, my immune system gradually weakens. I catch colds more often, develop shingles, and wounds take longer to heal.

Since the body remains in a state of tension, its ability to recover diminishes. Blood pressure and blood sugar can also be affected.

This is why doctors emphasize that managing stress is crucial for preventing high blood pressure and diabetes.

Interestingly, the body doesn't lie. No matter how much I say, "I'm fine," my body remembers all the stress it has endured.

However, it's impossible to live without stress. I encounter all sorts of issues in my business.

There are customer problems, worries about the economy, and family concerns. The key is not to eliminate stress but to develop a habit of relieving it daily.

These days, I intentionally walk for about 30 minutes. Even just walking enough to break a sweat clears my mind significantly. I sleep better too.

And I try not to drink coffee late in the afternoon. Just getting good sleep changes how I handle stress the next day.

Diet is also important. Skipping meals or only eating sweets makes the body more sensitive.

By ensuring I eat protein and vegetables, and drink enough water, I feel much more stable.

Health doesn't collapse overnight. The stress that builds up little by little often shows results years later.

That's why regular health check-ups are important, but it's even more crucial to listen to the signals my body sends every day.

If you've been feeling inexplicably tired, having trouble sleeping, noticing a growing belly, or becoming sensitive to minor issues lately, don't just brush it off as "just getting older."

Your body might be sending a signal saying, "Please reduce the stress."
