Fat Burning Genetic and Thermogenic Weight Loss will you keep your body warm. at sapien medicine
The Sun Gazer at dreamseeds
Excellent suggestions in this thread. Had tried a few of them. Instant effect.
You can complement the already suggested Sun Gazer with the other Sun track (see below). It had literally burned me during the first listenings lol, so I’ll probably use it this winter.
Also, you can have a look at the tracks which are in the Sacred Places albums. Some of them like Haleakalā, Sedona, Giza do the trick for me. It doesn’t mean that the actual places have always high temperatures, but sometimes you can catch the warmer side (and days) of their energies.
You’re all awesome, thank you!!
Infrared works so well for this I attuned myself and my ex-gf to it a week or so ago.
The Chi Elixir, Transmutation and Microcosmic, Soul/Core Energy Restoration and Soul Restoration (Heart storage Center) can help warm one from within as well. 
Here are a few posts about Soul Restoration (Heart Storage Center) by @_OM and @Atreides which might be of interest:
