How Long After Botox Can I Go to a Sauna?

There has been no evidence that heat from a sauna will interfere with Botox injections several days after the procedure. Exercise is permitted within  several hours after the procedure by most doctors.

After receiving Botox injections, it is just fine to be in sauna like temperatures the next day.

Botox, the neuromodulator has already settled into your muscles and is doing its work within minutes of injection. Neither a hot sauna nor Bikram yoga should have an effect on it. Please do use a board-certified dermatologist for Botox to get the best results.

Saunas won't negatively affect your Botox, but it can make swelling and bruising worse, as well as inflammation at the injection site. 

Hi Sydney.  We ask our patients to avoid heavy exercise for several hours after Botox injections.  The reason is that strenuous exercise can increase blood flow and (potentially) cause Botox to migrate.  

If you went to Yoga class 4 days after your injections it will not affect your results.

In most cases, I cannot see how performing Bikram yoga will alter the effects of Botox administered 4 days previously.

I think that what you've done is perfectly fine. Most plastic surgeons will advise you to not rub the injected area immediately after the injection. The thinking is that this will reduce diffusion and untoward muscle weakening. Four days after your injections, heat and exercise are totally fine and shouldn't affect your results.

It would have been helpful if you had been given enough information and instructions so that you would not worry after your treatment. Botox treatments require very minimal aftercare. For several hours after your treatment it is recommended to avoid vigourous exercise and heat because the increased circulation may promote bruising or diffusion of the medication. It is believed that after 6 hours the Botox is irreversibly attached to the target receptors at the nerve-muscle junction. Anything you do 4 days later will have no impact on the safety or effectiveness of your treatment.

Your botox treatment should work well despite your exposure to heat.
The only real recommendation following a botox treatment is to avoid massage I've the treated area immediately following the injection.
The botox will still work, however it may drift into an unintended area resulting in unintended results.

Since Botox irreversibly binds to the receptors that control neuromuscular function in the injected areas, by 4 days, most if not all of the Botox molecules are already bound to the target receptors (even though the total effect of Botox may not be completely evident for up to two weeks). Your body is 98.6 degrees, and even in a hot sauna your body tissues will be thermoregulated to that temperature except on the surface, so the Botox molecules are in an essentially unchanged environment.

You shouldn't need any additional Botox unless you see a definite difference compared to what you normally see. Relax and Om!
