現代人由於生活步調加速、不良之生活習慣與環境汙染影響而導致健康問題日益嚴重，其中心血管方面的疾病，如中風、高血壓、心臟病…等，已造成許多人的困擾，目前國內外均有許多針對心血管問題的研究，其中包含如服用藥物的侵入型治療，但在症狀輕微情況下，患者也有許多優良的非侵入式治療方法可選擇。根據文獻指出，遠紅外線可以刺激血管之內皮細胞生成一氧化氮，進而促使血管的擴張，增加血液流量並降低血壓，而本研究中係以石墨烯通電作為遠紅外線之產生源；石墨烯於通入電流後，能將90%電能轉換為熱能，其中也包括產生遠紅外線，且比傳統陶瓷源遠紅外線能量轉換效率更高；並於室溫下進行20~65歲成年人手腕處照射遠紅外線實驗，同時收集人體平均動脈壓、心跳率、血液流速、心臟輸血量與體溫的改變，最後計算各數值照射遠紅外線前後之百分比差異並以SPSS軟體分析探討。
研究結果發現，人體在照射遠紅外線後，除了心跳率之外其於數值均有明顯改變之趨勢，血液流速、心臟輸血量分別成長了64.9%與50.8%，而體溫則平均升高了0.8℃，平均動脈壓則降低了5.6%。
分析數據後可發現，人體於照射遠紅外線後末梢血液循環明顯有改善，但隨者年齡之增大，實驗前後之差異性隨之減少，並且各實驗數據均與人體BMI高低無顯著關係。

In recent years, the environment pollution and fast paced way of life are offering the health of humans, more humans were suffering cardiovascular diseases such as hypertension, heart attack. There are a lot of research focus on the treatment of cardiovascular diseases all over the world, which includes invasive therapy like taking medicine. However, there are lots of noninvasive therapy for patients having mild symptoms. According to the literature, far infrared radiation can stimulate the endothelial cells of blood vessel to produce nitric oxide, which promotes the expansion of blood vessels, increases the blood flow and decreases the blood pressure. In this study, graphene electrification was used as the source of far infrared radiation. When graphene is energized, 90% of electrical energy can be converted into heat which includes far infrared radiation. Moreover, by using the graphene, the conversion efficiency of far infrared radiation is higher than using the traditional ceramic as the source. In order to execute experiment, 20 to 65 years old volunteers for examination using far infrared radiation illuminated on their wrists at room temperature. Meanwhile, we collected the mean arterial pressure, heart rate, blood flow velocity and blood flow rate and body temperature. Finally, the percentage difference between each value before and after far infrared radiation were calculated and analyzed with SPSS software.
The results of the study found that after the human body was illuminated under far infrared radiation, except for the heart rate, its value changed significantly. The blood flow velocity and blood flow rate increased by 64.9% and 50.8% respectively, while the body temperature increased by an average of 0.8°C, and mean arterial pressure decreased by 5.6%.
In a nutshell, we observed that the human’s peripheral blood circulation is improved after illuminated under far infrared radiation. However, the difference of data before and after illuminated far infrared radiation is reduced with the increase in age. Besides that, each examined data of our research has no significant correlation with the BMI.
