Thank you for your inquiry.
Unfortunately, I am not aware of any reference, nor could I find such in the literature, stating that the optimal temperature to control the conditions you mentioned rests between 64 and 65 degrees. However, perhaps we are not your best source for this information. I would advise you to contact the individual’s personal physician who recommended these temperatures for a source document.
Thank you again for your inquiry.
