-Promotes psychological health and general wellbeing

First Use and Care Instructions

Start With Chill Kuzzi

Our Chill Kuzzi products should be introduced gradually to get the dog used to the new sensation. Use the product for a maximum of 4 hours for the first 2 to 3 days and then gradually increase by one hour at a time per day. After the introductory period, the products should be used for at least 8 hours per day for maximum benefit. But as little as one hour can have a positive effect on mood and will provide relief for tense muscles and stiff joints.

Initial Reactions to Chill Kuzzi Vary

The increased blood flow can in some cases cause some dogs to experience irritation, swelling, or tenderness in the problem area at first. The reaction is individual and everyone experiences the effect in different ways. The initial reaction may occur after only a few hours of use. If you notice discomfort in your canine, cease use for that day. Instead, try introducing the product more gradually over the next few days.

Please Note
Animals emit body heat during both rest and activity, so the products can be used at any time of day: before, during, and after activity.

Our Chill Kuzzi products work best when in direct contact with the skin.

Use the product only according to the instructions and consult a veterinarian if symptoms persist.

Chill Kuzzi Clinical Studies and Scientific Articles

Our innovative fabric technology supports better overall dog health by using naturally-occurring FIR Therapy (Far Infrared Rays) to stimulate blood circulation and oxygen flow.

This methodology is supported by years of countless studies and evidence-based articles. This collection of data supports our findings and has been corroborated in the field to simulate real-world conditions.

During the making of our polyester fibers, our proprietary ceramic material is embedded onto the fibers. When worn or used, these particles radiate the body's own energy back towards the body. This reflection is known as long-wave infrared radiation.

It is generally well-established and documented that long wave infrared radiation has a pain reducing effect and increases blood circulation.

Long wave infrared radiation penetrates the fur and skin and travels deep into tissue which makes the veins wider on the surface and deep in the muscles and around the joints. The increased blood circulation in the tissues relieves muscle tension and strengthens the body’s own natural ability to reduce inflammations and heal injuries. This application is therefore often used in cases where inflammation is part of the pain-causing condition.

Biological activities caused by far-infrared radiation

Inoué, S., Kabaya, M. Biological activities caused by far-infrared radiation. Int J Biometeorol 33, 145–150 (1989).

Contrary to previous presumption, accumulated evidence indicates that far-infrared rays are biologically active. A small ceramic disk that emits far-infrared rays (4-16 microns) has commonly been applied to a local spot or a whole part of the body for exposure. Pioneering attempts to experimentally analyze an effect of acute and chronic radiation of far-infrared rays on living organisms have detected a growth-promoting effect in growing rats, a sleep-modulatory effect in freely behaving rats and an insomiac patient, and a blood circulation-enhancing effect in human skin. Questionnaires to 542 users of far-infrared radiator disks embedded in bedclothes revealed that the majority of the users subjectively evaluated an improvement of their health. These effects on living organisms appear to be non-specifically triggered by an exposure to far-infrared rays, which eventually induce an increase in temperature of the body tissues or, more basically, an elevated motility of body fluids due to decrease in size of water clusters.


Analysis of serum cortisol levels by Fourier Transform Infrared Spectroscopy for diagnosis of stress in athletes

Fourier-transform infrared (FT-IR) spectroscopy is a technique with great potential for body fluids analyses. The aim of this study was to examine the impact of session training on cortisol concentrations in rugby players by means of infrared analysis of serum. Methods: Blood collections were performed pre, post and 24 hours after of rugby training sessions. Serum cortisol was analyzed by FT-IR spectroscopy and chemiluminescent immunoassay. Results: There was a significant difference between the integrated area, in the region of 1180-1102 cm-1, of the spectra for pre, post and post 24 h serums. The cortisol concentration obtained by chemiluminescent immunoassay showed no significant difference between pre, post and post 24 h. Positive correlations were obtained between the techniques (r = 0.75), post (r = 0.83) and post 24 h (r = 0.73). Conclusion: The results showed no increase in cortisol levels of the players after the training sessions, as well as positive correlations indicating that FT-IR spectroscopy have produced promising results for the analysis of serum for diagnosis of stress.


Physiological stress reactivity and recovery related to behavioral traits in dogs (Canis familiaris)

This study investigated whether stress responsiveness (in one context) can be used to predict dog behavior in daily life. On two occasions (NT1 = 32 puppies; NT2 = 16 young adults), dogs’ physiological stress response after a behavioral test at home was measured in terms of reactivity (10 min post-test) and recovery (40 min post-test) for three salivary markers: cortisol, chromogranin A (CgA) and secretory immunoglobulin A (sIgA). For each marker, it was determined whether dogs with a strong physiological response displayed different behavior in daily life compared to dogs with a weaker physiological response. The results revealed three main findings: first, for CgA and cortisol, different patterns were identified according to sample time. High reactivity related to desirable traits, whereas slow recovery after the behavioral test related to undesirable traits. The findings suggest that increased levels of CgA and cortisol 10 minutes after the behavioral test reflected an adaptive stress response, whereas elevated levels 40 minutes after the test reflected unsuccessful coping. Second, patterns for sIgA differed from CgA and cortisol: significant associations were only found with behavioral traits at T2, mostly considered desirable and related to Trainability. Possibly, the delayed reaction pattern of sIgA caused this difference between markers, as sIgA reflects the (secondary) immune response to stress, due to immunosuppressive effects of cortisol. Third, predictive capacity of puppies’ physiological stress response (T1) was inconclusive, and contrary relations were found with behavioral traits at T2, suggesting that developmental factors play an important role. This study provides new insights about the relation between stress physiology and behavioral traits, and methodological advice is given to study these patterns further. In conclusion, physiological markers could provide additional insights in dogs’ tendencies to display certain behaviors, especially at the young adult stage.


Oxidative stress and anxiety: Relationship and cellular pathways

High O2 consumption, modest antioxidant defenses and a lipid-rich constitution make the brain highly vulnerable to redox imbalances. Oxidative damage in the brain causes nervous system impairment. Recently, oxidative stress has also been implicated in depression, anxiety disorders and high anxiety levels. The findings which establish a link between oxidative stress and pathological anxiety have inspired a number of other recent studies focusing on the link between oxidative status and normal anxiety and also on a possible causal relationship between cellular oxidative stress and emotional stress. This review examines the recent discoveries made on the link between oxidative status and normal anxiety levels and the putative role of oxidative stress in genesis of anxiety. We discuss the different opinions and questions that exist in the field and review the methodological approaches that are being used to determine a causal relationship between oxidative and emotional stress.


Promotive Effects of Far-Infrared Ray on Full-Thickness Skin Wound Healing in Rats

The biological effects of far-infrared ray (FIR) on whole organisms remain poorly understood. The aim of our study was to investigate not only the hyperthermic effect of the FIR irradiation, but also the biological effects of FIR on wound healing. To evaluate the effect of FIR on a skin wound site, the speed of full-thickness skin wound healing was compared among groups with and without FIR using a rat model. We measured the skin wound area, skin blood flow, and skin temperature before and during FIR irradiation, and we performed histological inspection. Wound healing was significantly more rapid with than without FIR. Skin blood flow and skin temperature did not change significantly before or during FIR irradiation. Histological findings revealed greater collagen regeneration and infiltration of fibroblasts that expressed transforming growth factor-β1 (TGF-β1) in wounds in the FIR group than in the group without FIR. Stimulation of the secretion of TGF-β1 or the activation of fibroblasts may be considered as a possible mechanisms for the promotive effect of FIR on wound healing independent of skin blood flow and skin temperature


Direct and Indirect Effects of Ceramic Far Infrared Radiation on the Hydrogen Peroxide-scavenging Capacity and on Murine Macrophages under Oxidative Stress

Far infrared (FIR) rays are used for many therapeutic purposes, but the intracellular mechanisms of their beneficial effects have not been entirely elucidated. The purposes of this study were thus to explore the effects of ceramic-generated far infrared ray (cFIR) on RAW 264.7 cells by determining the scavenging activity of hydrogen peroxide (H2O2), cell viability, and changes in cytochrome c levels and the NADP+/NADPH ratios. The results showed that the H2O2-scavenging activity directly increased by 10.26% after FIR application. Additional FIR treatment resulted in increased viability of murine macrophages with different concentrations of H2O2. cFIR significantly inhibited intracellular peroxide levels and LPS-induced peroxide production by macrophages. The increased ratio of hypodiploid cells elicited by H2O2 was significantly reduced by cFIR. The effects of cFIR on H2O2 toxicity were determined by measuring intracellular changes in cytochrome c levels and the ratio of NADP+/NADPH, and results showed that cFIR may block ROS-mediated cytotoxicity. In conclusion, data from this study suggest that cFIR may possess antiapoptotic effects by reducing ROS production by macrophages. We also review past articles related to the effects of oxidative stress from metabolically produced H2O2, and discuss possible beneficial effects of cFIR on living tissues.


Effects of Far-Infrared Therapy on Foot Circulation Among Hemodialysis Patients With Diabetes Mellitus

Background: Far-infrared radiation (FIR) therapy improves vessel dilation, circulation, vessel endothelial function, and angiogenesis and reduces atherosclerosis. However, evidence of FIR therapy’s effects on foot circulation among diabetic patients undergoing hemodialysis is scarce. Aim: To determine whether FIR therapy improves foot circulation in diabetic patients undergoing hemodialysis. Design: Quasi-experimental. Methods: In June to November 2017, diabetic patients undergoing hemodialysis (N ¼ 58) at a hemodialysis center in northern Taiwan were divided into two groups: the experimental group (n ¼ 31) received FIR therapy to the bilateral dorsalis pedis artery (40 min/session, 3 times/week for 6 months) and the control group (n ¼ 27) received conventional dialysis care. Paired t test, independent samples t test, two-proportion Z test, and repeated-measures analysis of covariance were performed to compare changes from baseline to the end of the 6-month intervention between the groups. Results: Significant positive effects of FIR therapy on temperature, pulse, and blood flow of the dorsalis pedis artery were observed. Sensitivity to pain, tactility, and pressure also improved significantly in the experimental group. The Edinburgh Claudication Questionnaire revealed that the experimental group had reductions in subjective experiences of soreness, tingling, and coldness in the feet. Conclusion: The findings of significant improvements to objective and subjective measures of blood flow and neural function in the experimental group indicate that FIR therapy improves blood circulation to the feet. This therapy thus has great potential to be an effective adjuvant treatment for patients with diabetes mellitus undergoing hemodialysis.


Effects of far-infrared radiation lamp therapy on recovery from muscle damage induced by eccentric exercise

The present study investigated the effects of a far-infrared radiation (FIR) lamp therapy on changes in muscle damage and proprioception markers after maximal eccentric exercise of the elbow flexors (EF: Study 1) and the knee flexors (KF: Study 2) in comparison to a sham treatment condition. In each study, 24 healthy sedentary women were assigned to a FIR or a sham treatment group (n = 12/group). They performed 72 maximal EF eccentric contractions (Study 1) or 100 maximal KF eccentric contractions (Study 2) with their non-dominant limbs. They received a 30-min FIR (wavelength: 8–14 µm) or sham treatment at 1, 25, 49, 73 and 97 h post-exercise to the exercised muscles. Maximum voluntary isometric contraction (MVC) torque, muscle soreness, plasma creatine kinase activity, and proprioception assessed by position sense, joint reaction angle, and force match were measured before, and 0.5, 24, 48, 72, 96 and 120 h post-exercise. The outcome measures showed significant changes (P < 0.05) at 0.5-hour post-exercise (before treatment) similarly (P > 0.05) between the conditions in both studies. However, changes in all measures at 24–120 h post-exercise were smaller (P < 0.05) for the FIR than sham condition in both studies. For example, MVC torque returned to the baseline by 72 h post-exercise for the FIR condition in both studies, but was still 19 ± 6% (Study 1) or 17 ± 12% (Study 2) lower than the baseline at 120 h post-exercise for the sham condition. These results suggested that the FIR lamp therapy was effective for accelerating recovery from muscle damage.


Clinical utility of far-infrared therapy for improvement of vascular access blood flow and pain control in hemodialysis patients

Maintenance of a well-functioning vascular access and minimal needling pain are important goals for achieving adequate dialysis and improving the quality of life in hemodialysis (HD) patients. Far-infrared (FIR) therapy may improve endothelial function and increase access blood flow (Qa) and patency in HD patients. The aim of this study was to evaluate effects of FIR therapy on Qa and patency, and needling pain in HD patients.
