Apple watch Series 8 -Alarms

I take medication throughout the day and I depend on my watch Alarms to buzz off to remind me to take my meds.

Recently my alarms shut themselves off and if I go back and click the alarm toggle back on it does it again. It’s always the alarms between 5am-5:30am and 8am-8:30am … I really need suggestions on how to permanently fix this major issue. I do use the sleep features but I don’t understand how this can cause alarm issues.

Thanks
