Brain and Nervous System, How it relates to Stress? We all deal with it. But have you ever stopped to think — Can you imagine what exactly your brain is doing with you at that time? In this blog you will get to know the brain functions and How Stress Affects the Brain and Nervous System?
Let’s say you’re stuck in traffic, you are running late, and your phone’s buzzing. Your thoughts are racing and the tight feeling in your chest. It means the stress of taking the driver’s seat. Here’s the twist: it’s not just “in your head.” It’s reshaping your brain and messing with your nervous system quietly and slowly.
Let’s break it down. Not like a textbook. Like a real-life story — yours, mine, all of ours.
The Brain’s Panic Button
When stress hits, your brain doesn’t ask politely, “Is everything alright?” No. It hits the alarm button very hard. The amygdala (your brain’s emotion Headquarter) wakes up fast like a guard dog. The hypothalamus then signals the adrenal glands to release stress hormones like cortisol and adrenaline. Once these are released, your heart races, breathing becomes faster, and muscles tense up. Sounds familiar?
In small doses, this is helpful. You focus and move quicker. You survive, but when this happens all the time — it’s like your body thinks it’s in danger 24/7.
What Stress Really Does to the Brain
Okay, so what will happen in the long run?
1. Memory and Focus are messed up.
Your hippocampus, which handles memory, shrinks with long-term stress. You start forgetting things, and can’t concentrate. That “brain fog” you feel and that’s real!
2. Decision-Making will be a puzzle.
Your prefrontal cortex, which helps with planning and thinking clearly, slows down. The stress makes you more impulsive, and more reactive.
3. Your Mood Goes for a Ride
Anxiety, sadness and anger are all major symptoms of Chronic stress. It messes with the brain’s ability to regulate emotions.
How to know the Nervous System is under pressure?
Your nervous system controls everything — from blinking to running marathons, and maintaining stress.
• The Sympathetic Nervous System gets stuck in overthinking. You stay in “fight-or-flight” mode.
• The Parasympathetic Nervous System — which calms you down and gets pushed aside.
Common symptoms of weak nervous system:
• Shaky hands
• Fast heartbeat
• Sweating
• Even digestive problems

Real Talk: It’s Not All Doom
Your brain is amazing. It can heal and grow. It’s called neuroplasticity — the brain’s way of rewiring itself.
How to Reverse Your Brain from Stress (Naturally):
1. Breathe Like You Mean It (Yoga)
Deep belly breathing calms your nervous system in minutes. Do it every morning or when stress spikes.
2. Move Your Body (Exercise)
Exercise helps you in weight loss, but it boosts the brain chemicals like dopamine and serotonin as well. Even a 20-minute walk helps a lot and activates your cells and keeps you stress free.
3. Sleep = Brain Repair
Stress can wreck your sleep. And poor sleep increases stress. Break the cycle — aim for 7–8 hours, every night.
4. Feed Your Brain Right (Diet)
Omega-3s, leafy greens, berries. Eat those foods in your diet that help reduce inflammation and protect brain cells.
5. Talk It Out
Stress builds up if we don’t talk. Share with a friend, in a Journal. Or speak to a therapist. No shame in it.
