Can someone tell me why my mother sleeps so much? Every time I turn around I find her sleeping again.

she sleeps during the night, in fact i have to wake her sometimes if we have dr appts. I sometimes have to make her go to bed at night. Thats why I am putting her in adult day care to get more physical activity, She starting to worry me with the sleeping and sitting around moaning or complaining

I myself had sleep apnea for many years. The only reason I would fall asleep during the day was because I was NOT sleeping at night. Is she going to bed too early? Is she sleeping through the night? Maybe she needs a little more physical activity during the day to let her wear off any excess energy she has.
