Bash function loop every X time

Question

im doing a script to gather and clean some logs, but im thinking the best way is to put inside a function because runs in different lapses. But there are some commands that only runs once not in loop.

## Runs every 24 hours
    while :
    do
    cp file/logs ~/new/path
    touch file/logs
    sleep 86400
done

## Show the Lines and send message
while :
do
    wc -l logs | send_notification 'INFO'
    sleep 3600
done

Is there a way that make that inside a function or what is a good way to make the two loops works?
