Dear [Sister’s Name],
I hope you're doing well. I’m writing to discuss the downsides of watching television for long hours. While television can be both entertaining and educational, excessive watching can have negative impacts on both health and studies.
Watching too much TV can harm your eyesight, reduce focus in studies, and encourage a sedentary lifestyle. It takes away time that could be spent on more beneficial activities such as reading, playing sports, or socializing with family and friends. Additionally, long hours in front of the screen can disrupt your sleep cycle, leaving you feeling tired and lethargic.
It’s important to find a balance between enjoying TV and staying active. I hope you take this advice seriously.
Take care.
Your loving brother/sister,
