Hello! Welcome back to my blog! For Health today we are going to research an area of medicine! I picked Neurology. Neurology is the branch of medicine that looks ate our nervous systems, and basically our brain, spinal cord, and all the nerves running throughout the body. Your brain literally controls everything you do, how you move, and sending signals to your body.
How Neurology Impacts Hauora
Taha Tinana – Positive impact: When our nervous system works well, our reflexes are sharp, our muscles react quickly, and we don’t feel any random pain. Getting enough sleep and wearing a helmet while riding a bike keeps out brain safe and healthy. Short term: Getting a minor bump on the head or a headache can make us feel tired or dizzy for a while. Long Term: Issues like migraines or severe concussions can permanently change how someone moves, sleeps, or manages pain. 
Taha Hinengaro – Positive impact: A healthy brain helps us process feelings, stay focused in class, and handle stress. Short Term: Being tired or overwhelmed makes our brain fog up, this makes us easily annoyed or moody all day. Long Term: Damage to the brain can lead to long term anxiety, depression, or maybe the difficulty of learning.
Taha Whānau – Positive Impact: Our brain lets us ready body language, pick up on tone of voices, and stay connected with our friends and family. Short Term: When our brain is drained or stressed, we might accidentally snap at our friends or isolate ourselves. Long term: Serious brain conditions can change how someone’s personality or memory is, making it tough on family members to change how someone interacts.
Taha Wairua – Positive Impact: Feeling mentally sharp helps us feel confident about who we are and it helps us with our sense of purpose. Short Term: Stress can make us feel completely disconnected from what we care about. Long term: Long term struggles can make people feel like they’ve lost a piece of their identity or their place in the community.
3 Questions about Neurology
1. How fast do messages travel through our nervous system? Up to 120 metres per second. That’s the reason why you pull your hand away from a hot stone before you even have the time to think.
2. Does our brain actually rest when we sleep? No, the brain never turns off. While we sleep, our brain clears out toxic waste products built up during the day, it also organizes memories from school, and repairs things.
3. Why do we get a brain freeze? When something super cold touches the roof of your mouth, the blood vessels shrink and then expand rapidly as they warm up. This sends a panic signal to your brain. And then your brain mistakenly thinks that the signal is coming from your forehead.
Fun Fact!
Your brain generates about 20 watts of electricity while you’re awake, which is also enough power to light up a small LED light bulb.
