    „Ich hatte zuvor ein langes Wärmflaschenmodell, das ziemlich schwer war, und die Wasserverteilung hat mich genervt. Diese hier ist hingegen echt leicht und dadurch super für den Alltag. Ich empfehle sie sehr!“

    Tanya

    “This is the most stylish and well thought-out hot-water bottle solution ever. Absolutely worth the money. People keep on asking me where they can buy it :)) Thank you all! ”

    Vivien

    „Ich bin so dankbar, dass es endlich eine Wärmflasche gibt, die hochwertig, schön und fashionable ist! Ich trage sie grad im Winter wirklich jeden Tag, zuhause und auch unterwegs! Vor allem bei Menstruationsschmerzen oder Muskelkater ist es super sie einfach tagsüber umzuschnallen. Ein echter Gamechanger! Der Gurt ist gut verarbeitet und super soft und hat sogar eine kleine Tasche :) Nie wieder ohne <3"

    "I have a whole collection of hot-water bottles and matching scarfs to treat my endometriosis. However, I have been looking for ethical and social responsible alternatives. Therefore, the offer to test the product came just at the right time..and UCB exceeds my expectations: Ethical, a contemporary design and it definitely fits my wardrobe!“

    Paula

    „Jetzt, wo ich endlich auch meine Foundly Wärmflasche habe, verstehe ich, warum sie ständig ausverkauft sind. Tolles Design und funktional. Absolute Empfehlung, wenn ihr eine ergattern könnte :P!“

    Heat Therapy and Pain Relief:

    Scientifically Proven Benefits
    of Heat

    Why does heat help?
    Studies have proven that heat has a similar effect to a painkiller, effectively “deactivating” pain at a molecular level. In this way, completely naturally and without any chemicals, heat blocks pain and helps with issues such as menstrual pain, neck tension and abdominal cramps, and even diseases such as endometriosis or Crohn’s disease.
