Why Stress Feels Overwhelming
We have all been there. A racing heartbeat before a presentation, sweaty palms in traffic, or lying awake at night replaying a conversation. Stress is part of being human, and in small doses it can actually help us focus and perform better. But when stress becomes constant, it does not just drain your energy. It can literally change your brain.

7 effective strategies to stay calm and sharp in 2025
The surprising thing? Stress isn’t always bad. In small doses, it can sharpen your focus, boost memory, and even push you to perform better. The problem comes when stress doesn’t shut off. That’s when it can literally make you less smart.
Let’s dive into why stress makes us “stupid” and more importantly what you can actually do to turn the tables.
How Stress Affects the Brain
Stress isn’t just a feeling, it’s a chain reaction in your body. When you’re stressed, your brain releases cortisol [1] and adrenaline, which affect hormones like insulin, thyroid, and growth hormones. In short bursts this is fine. But chronic stress? That’s where the damage begins.
Stress Shrinks Your Decision Making Brain
Studies have shown that long term stress can shrink the prefrontal cortex, the part of your brain that helps you make decisions, control impulses, and solve problems.[2] Imagine trying to run a company with fewer staff every week, that’s what’s happening in your head.
Stress Messes with Emotional Intelligence
Stress also affects how you relate to people. [3] You might snap at a friend, misread someone’s tone, or find it hard to manage your own emotions. This not only makes relationships harder but also limits your ability to think clearly in stressful situations.
The bottom line? Stress can make you forgetful, moody, indecisive, and even less empathetic. In other words, stress really can make you “stupid.”
Flipping the Script: Turning Stress Into an Ally
Here’s the good news: stress doesn’t have to be your enemy. In fact, you can retrain your brain to see stress as excitement. Think about it, physically anxiety and excitement feel the same. Your heart races, your palms sweat, and your breathing gets faster. The only difference is the story you tell yourself.
Next time you’re nervous about giving a presentation or going to a job interview, try saying “I’m excited for this opportunity” instead of “I’m so anxious.” This small shift can trick your brain into feeling more confident and in control.
Another trick? When your body reacts to stress with a fast heartbeat and quick breathing, thank it. Say “Great, more oxygen for my brain. Now I can think clearly.” Treat stress like a coach instead of a critic.
7 Fresh Ways to Lower Stress (That You Might Not Have Tried)
Most articles will tell you to eat well, sleep better, and exercise, and yes, those work. But let’s go beyond the usual advice. Here are seven creative, science backed, and friendly to try methods for managing stress:
1. Try Microbreaks Throughout Your Day

Instead of waiting for the weekend to relax, sprinkle mini breaks into your day. Just two minutes of stretching, sipping water mindfully, or standing in the sunshine can reset your stress levels. Research shows these microbreaks improve focus and reduce fatigue.
If you want to stay focused and calm at school or work, try Savvy Brain Boost — a natural way to get steady energy all day without the jitters. [4]
2. Practice Box Breathing

This is a Navy SEAL trick, and it’s as simple as it sounds. Inhale for 4 seconds, hold for 4, exhale for 4, and hold again for 4. Repeat a few times. It slows your heart rate and signals your brain to relax. [5] Bonus: you can do it anywhere, even during a stressful meeting.
3. Add a Splash of Cold

Cold exposure is trending for a reason. Splashing cold water on your face, taking a brisk cold shower,[6] or even holding an ice cube can activate your vagus nerve, which calms the nervous system. It’s like hitting a reset button for your stress response.
4. Keep a Worry Journal

Instead of letting anxious thoughts swirl in your head, write them down.[7] Set aside 10 minutes at night to unload all your worries onto paper. This tricks your brain into thinking it’s handled, so you don’t keep cycling through the same thoughts.
5. Try Aromatherapy for Instant Calm

Certain scents like lavender, bergamot, and peppermint have been shown to lower cortisol levels. Keep a roll on essential oil or diffuser nearby. Sometimes, all it takes is a deep breath of something soothing to shift your mood.[8]
6. Play More (Seriously)

Play isn’t just for kids. Dancing in your living room, playing fetch with your dog, or even gaming with friends releases endorphins and reduces stress. Play lowers defenses, sparks creativity, and reminds your brain that life isn’t all deadlines and to do lists.[9]
7. Disconnect to Reconnect

Stress often sneaks in through screens, emails, notifications, and endless scrolling.[10] Try a digital detox for even just an hour a day. Use that time to cook, walk, or chat face to face with someone. You’ll notice your mind feels lighter almost immediately.
Final Thoughts: Stress Smarter, Not Harder
Stress is part of life, we can’t avoid it. But the way we handle it makes all the difference. Left unchecked, stress can shrink your brain, lower your emotional intelligence, and yes, make you feel “stupid.” But reframing stress, taking fresh approaches like microbreaks, cold therapy, and worry journaling, can help you turn it into fuel instead of a roadblock.
At Savvy we believe in supporting a calmer, sharper you with natural solutions. Whether it’s through lifestyle changes, community support, or wellness products, the goal is the same, help you feel your best even when life feels overwhelming.
