Thanks for the query.
I understand your concern.
Usually blood pressure below 90/60 mm of hg is considered as low blood pressure.
Low blood pressure can lead to lightheadedness sometimes.
Blood pressure can vary with position, usually it will be lower during nights in the supine position and can gradually increase after waking up.
As your blood pressure is rising without any intervention, there may not be any major problem.
Low blood pressure, blood loss due to surgery can lead to lightheadedness.
Taking rest and drinking more water can improve the symptoms.
If symptoms persist even after doing these, better to consult your doctor and get evaluated.
Hope this helps.
