近年來，許多青年因生活壓力、飲食習慣、生活作息和不良嗜好…等，造成心血管或心臟等相關疾病的案例逐漸增加，醫學上針對相關的題目進行研究尋找改善的方式，其中研究證實石墨稀能散發遠紅外線並改善人體血液循環。本研究透過能發射遠紅外線波長為6.3 μm之塗佈石墨稀陶瓷片，針對18~23歲男性腳底末梢進行照射，並比較照射前後差異。
研究結果發現，腳底末梢照射遠紅外線後能顯著上升體溫(BT)上升約2.9 %、心跳(HR)上升約3.0 %、心搏指數(SI)上升約18.4 %、心輸出指數(CI)上升約18.5 %，並顯著降低周邊末梢血管阻力(TPR)約16 %。

The number of cases relevant to cardiovascular or heart related diseases, due to life stress, diet preference, daily life and bad habits, etc., has gradually increased in young people in recent years. Medical studies have been conducted to seek the relevant ways to improve the related problems. It is confirmed that graphene can emits far-infrared wave to improve blood circulation of human. In this study, a thin graphene coated ceramic sheet that emits a far-infrared wave with a wavelength of 6.3 μm was used to irradiate the peripheral of men’s feet from 18 to 23 years old, and the results prior to and subsequent to the irradiation were compared.
The results indicated that far infrared irradiation on the peripheral of human feet could significantly increase the body temperature (BT) by 2.9 %, heart rate (HR) by 3.0 %, stroke index (SI)by 18.4 %,and cardiac index (CI) by 18.5 %, and significantly reduce total peripheral resistance (TPR) by 16.0%.
