Sauna/Gym and Rhinoplasty, when is it safe?

Your timing is perfect. Though I always address the question about exercise
following rhinoplasty and other plastic procedures, I just had one of my
patients inquire as to the safety and timing of a sauna. In my opinion, keeping
exercise and extreme temperatures to a minimum for the first three weeks and
then easing into exercise over the next three weeks will enable you to feel good
and maintain your physical and mental sanity, while minimizing potential adverse
effects to your surgical procedure. I fear that exercise and sauna too
prematurely will lead to prolonged swelling of the nose, especially of the tip.
Your surgeon may have another opinion and I would definitely pose the same
question to them.

Thanks for asking. Talk with your plastic surgeon as he/she knows what to expect from your specific case. Rhinoplasty surgery is often very individualized and what you need may vary from another person. I usually allow more extreme temperatures after some time and after full healing in my patients. This also pertains to the upper lip which is still early in the healing. Talk with your surgeon. Good luck

Only your surgeon knows exactly what was done during your operation.  I would suggest speaking with them in regards to post-operative instructions.
