Hello, thanks for the query.
As your B P was 114/64, age 52 yrs.
Amazing and very nice it seems that you are in the air.
This is a clear sign that your's is an athletic body and each and every thing is normal.
Neither it was due to dehydration
, but it was a normal condition.
Here I would like to say that keep it up.
Perhaps you are doing regular exercise and living a tension free life so enjoy it. Regards.
