40 degrees Celsius how?

So I want to want “Therapeutic heat: ideal heat should be 102 to 110 F (38.9- 43.3 C)” to make my tunica work with me. How is this best achieved? Heatingpad or what?

Ultrasound is the answer , search for Kyrpa’s ultrasound thread in the search tab .

I searched for some devise to buy but can’t find it. Can someone link it please?

maybe before buying anything you should check what is done and what ere your options depending on what is your situation.
What is your situation regarding PE, newbie, seasoned PEer?

If i was you before buying anything i would read and re read theses threads :

Using the ultrasound for therapeutic heat in PE

Igigi’s quest for the foot long with UltraSound Therapy

I would also take a look at TuTT’s threads.

Therapeutic range is doable with both Heatpad and Ultrasound, respectively passive and active. The one you choose to use will dictate your kind of exercises.

I got the totalman heating pad and it reports on its site that it gets up to those levels

Per Kyrpa’s research (highly technical and well reasoned) whether a surface temp on an ordinary or IR pad gets to the level is really irrelevant. The goal is the internal temp, which unfortunately requires a far higher surface temp for long periods to achieve the target temp at depth (at the septum in particular). The result can be skin damage. This is where US comes in as it penetrates to depth, while not having much heat at the surface. I do think IR pads may do a bit better, and my experimentation with red light and near IR indicates that may be the way to go for pads (really heats the tissues). But, I suspect the US remains the best way to actually target the deeper tissues, and the tough septum which appears to be the main impediment to length at least at some point. There is a library of knowledge and experience readily available per the links posted above.

I never found a link to the actual US tool or where to buy it.
