My grandma sleeps around 18 hours a day.
She is always exhausted.
This morning she wouldn’t even answer us or open her eyes when we tried to get her up at the normal time.
This is only the second time this has happened but it is quite scary. She finally responded 2 hours later, the rest of the day was like a typical day. She said she could hear us but was too tired to respond.
She has people around her all the time but there isn’t much she enjoys.
He went from sleeping 12 hours to 20 hours or more as he declined. He would wake to eat, when I changed him or repositioned him.
There is a great pamphlet that you can read on line that explains a lot of the sleeping and what it does. The pamphlet is called Crossing the Creek.
You will find as you start to age that you will start to notice you don't have the same energy for things you had when back in your 40's and 50's. That is very normal. I am in my mid-70's and just taking a shower/washing my hair feels like a work-out at a gym :P
Have Grandma see her primary doctor, and have the doctor run blood work to see what are Grandma's Vitamin B level. It could be low, and that would make anyone feel like dozing off. It's worth checking into.
