* Your health: Going to school while sick can worsen your illness and potentially lead to complications. Rest is crucial for recovery.
* The health of others: You could easily spread your illness to classmates and teachers, causing them to miss school and potentially get seriously ill, especially if it's contagious.
* Your ability to learn: When you're sick, you're likely to have difficulty concentrating and participating in class. You'll likely learn less effectively.
If you're feeling unwell, stay home, rest, and contact your doctor or parent/guardian if necessary.
