Overthinking? Take Control of Your Thoughts

Overthinking triggers the same stress response as physical danger   

Flooding Your Body With Cortisol

And if that’s happening on a daily basis? It’s not just uncomfortable, it’s toxic. Chronic stress from overthinking can damage your immune system, memory, sleep, digestion, and even your heart. (Source: NIMH)

But here’s the thing: you can stop the spiral.
You can interrupt the loop, reclaim your calm, and finally feel like yourself again. 

The Junk Mail You Keep Rereading

You know that pile of junk mail sitting by the door? The one you keep meaning to toss, but for some reason, you glance at it one more time—just in case?

That’s how overthinking works.

Your brain thinks there’s something important in there. A warning. A clue. Some loose end you forgot to tie up. So you keep mentally rereading it—even though the message hasn’t changed.

But here’s the truth:
Most of it is just mental spam.
And the more space it takes up, the less room you have for peace.

1. What Is Overthinking (And What It’s Not)

Let’s start with this: overthinking is normal.
Everyone does it sometimes. But when it becomes constant, exhausting, or interferes with your life, that’s when it needs your attention.

Two main types of overthinking:

• Rumination = replaying the past
• Worry = obsessing about the future

It shows up as:

• Replaying old conversations
• Struggling to fall asleep
• Feeling stuck on a work mistake
• Obsessing over what someone might think

This isn’t everyday concern—it’s when thoughts loop endlessly and hijack your focus, mood, and time.

2. Why Overthinking Happens

Here’s what most people miss: overthinking is a defense mechanism.

Your brain is trying to protect you, from regret, from failure, from uncertainty.
It believes that if you just think hard enough, you can solve the discomfort.

But it doesn’t solve anything.

It’s like checking the same locked door ten times in a row.
You don’t feel safer, you just get stuck.

Overthinking burns emotional fuel without getting you anywhere. And that’s why it’s so exhausting.

3. What Happens If You Don’t Let Go

Chronic stress doesn’t just affect your mood, it affects your body.
According to the National Institute of Mental Health – NIMH and American Medical Association – AMA, long-term overthinking can lead to:

• Weakened immune system
• Sleep disturbances
• Digestive issues
• Cardiovascular problems
• Memory issues

It can also show up emotionally as:

• Indecision
• Insomnia
• Constant self-criticism
• Irritability
• Feeling like you can’t turn your brain off

 You may be stuck in a loop. And loops can be interrupted.

4. The Shift: You Can Train Your Brain to Let Go

A. Daily Practices to Build Mental Strength

Letting go isn’t something you “decide” once. It’s a skill.
And like any skill, it gets stronger with practice.

Start here:

• Journaling with a timer: Write out your worries for 10 minutes, then stop.
• Gratitude practice: List three things you’re grateful for. This breaks the negative feedback loop.
• Mindfulness: Notice when your thoughts drift. Gently bring them back to the present.
• Self-compassion: Talk to yourself the way you’d talk to a friend. Use affirmations like, “It’s okay to not have all the answers today.”
• Therapy or trusted conversations: Don’t isolate. Sharing helps you process and release.

B. In-the-Moment Rescue Tools

When you’re in the thick of a spiral, try this 5-step process:

1. Name the feeling. “I feel anxious,” or “I feel overwhelmed.”
2. Name the thought. “I keep thinking I messed that up.”
3. Reframe the thought. Ask, “What else could be true?” or “Is this thought helping me?”
4. Do something physical. Walk. Breathe. Take a shower. Watch a funny video.
5. Take action. Even a small step, like sending one email, stretching for five minutes, helps break the loop.

5. What Letting Go Looks Like

Here’s something personal:
When I moved to a new city, I thought starting fresh would calm my anxiety.

But it didn’t. It just followed me into every unfamiliar street and decision, because I hadn’t yet changed how I responded to not knowing what comes next.

Letting go didn’t mean I stopped caring.
It meant I stopped gripping everything so tightly.

Letting go is recognizing: This isn’t mine to control.
And choosing to return to the present moment, over and over again.

“You don’t live in the past or future. You live here and now.”
