Chronic stress means being worried or scared all the time, for a really long time. It's like feeling scared of a monster under your bed, but instead of it being just at night, it's all the time.
Your body is made up of different parts, including your brain and your heart. When you feel stressed, your brain tells your heart to beat faster and your muscles to tense up. This is because your body is getting ready to run away, fight, or hide from whatever is scaring you.
When you feel stressed all the time, your body starts to get tired. It's like running a marathon every day, instead of just one time. Your heart and muscles get tired from being on high alert all the time.
This can cause problems like headaches, stomach aches, trouble sleeping, and feeling sad or worried all the time. It's important to find ways to calm down and relax, like doing fun activities, spending time with friends and family, or talking to someone you trust.
