最新研究發現，紅外線桑拿療法在類風濕性關節炎與強直性脊柱炎患者中表現出顯著效果。在為期四週的治療期間，患者經歷了疼痛和僵硬度的顯著減少，同時疲勞也有所改善。這項治療不僅被良好地耐受，且未觀察到任何不良反應，為這些慢性疾病患者提供了新的希望。

紅外線桑拿對於類風濕性關節炎和強直性脊柱炎患者的效果。一項初步研究顯示良好的耐受性，短期內疼痛和僵硬度的改善，以及傾向於長期有益效果的趨勢。

為了研究紅外線（IR）桑拿（一種全身加熱療法）對類風濕性關節炎（RA）和強直性脊柱炎（AS）患者的效果，患者在4週內接受了八次IR治療。研究了17名RA患者和17名AS患者。IR被良好地耐受，且沒有報告不良效果，疾病沒有惡化。疼痛和僵硬度臨床上減少，且在IR治療期間，改善是統計學上顯著的（RA和AS患者分別為p < 0.05和p < 0.001）。疲勞也減少了。在治療期間，RA和AS患者平均感覺舒適，尤其是治療後。在4週的治療期間，RA和AS患者的疼痛、僵硬度和疲勞也表現出臨床上的改善，但這些並未達到統計學上的顯著性。沒有發現疾病活動得分的相關變化，這表明疾病活動沒有加劇。結論是，紅外線治療在治療期間對RA和AS患者有統計學上顯著的短期有益效果和臨床上相關的周期效應，而不會加劇疾病活動。IR具有良好的耐受性且沒有不良反應。

To study the effects of infrared (IR) Sauna, a form of total-body hyperthermia in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) patients were treated for a 4-week period with a series of eight IR treatments. Seventeen RA patients and 17 AS patients were studied. IR was well tolerated, and no adverse effects were reported, no exacerbation of disease. Pain and stiffness decreased clinically, and improvements were statistically significant (p < 0.05 and p < 0.001 in RA and AS patients, respectively) during an IR session. Fatigue also decreased. Both RA and AS patients felt comfortable on average during and especially after treatment. In the RA and AS patients, pain, stiffness, and fatigue also showed clinical improvements during the 4-week treatment period, but these did not reach statistical significance. No relevant changes in disease activity scores were found, indicating no exacerbation of disease activity. In conclusion, infrared treatment has statistically significant short-term beneficial effects and clinically relevant period effects during treatment in RA and AS patients without enhancing disease activity. IR has good tolerability and no adverse effects.
