I Am A 75 Year Old Female. It's Been More

I am a 75 year old female. It's been more than 2decades since I've been on any prescribed or over-the-counter drugs or medicines. I've only been hospilitalized for giving child birth. I have not had any surgeries.
At this time, I have no pain, nausea or vomiting. I've not had any shortness of breath when walking up a flight of stairs. However, upon awakening & lifting my head from my pillow this morning, it seemed as if the whole room was spinning! This lasted for maybe a minute when I decided to turn my head in the opposite direction from which the room was spinning, I was able to get up, but I've been very cautious while walking today..!
What can I do to holistically take care of this problem. Thanks in advance for your advice!
