The application of far-infrared blankets has shown certain benefits in health promotion and therapy, such as improving blood circulation and alleviating muscle pain. However, the effects of such blankets on increasing deep sleep, reducing blood pressure, enhancing memory, dilating microvessels for blood flow, reducing chronic inflammation, and decreasing fatigue remain to be studied. We aim to investigate the effects of the DAZZEON αSleep far-infrared blanket on these indicators. This study adopted a double-blind design, recruiting 24 male participants aged over 45 years, divided into two groups of 12 each: (A) a placebo group and (B) a DAZZEON αSleep group. The participants used the blanket every night for two weeks, with sleep records taken using a wearable device and blood pressure, blood oxygen levels, arterial stiffness, and surface temperature measured before and after the intervention. Blood samples were collected for an analysis of inflammation and sleep-related blood indicators (serotonin and melatonin), and exercise tests were conducted to assess fatigue improvement. Compared with before the intervention, the blanket significantly increased changes in grip strength and reaction time. Additionally, it significantly increased blood serotonin, melatonin, and nitric oxide concentrations ( < 0.05), thus significantly increasing deep sleep and REM sleep durations ( < 0.05) and improving subjective sleep quality ( < 0.05). This study confirmed that using the DAZZEON αSleep far-infrared blanket for 14 consecutive days helps to improve blood circulation, reduce vascular age and arterial stiffness, increase serotonin and melatonin levels, and improve sleep quality, as well as enhances muscle strength and reaction time.
远红外毛毯的应用在健康促进和治疗方面已显示出一定益处，如改善血液循环和缓解肌肉疼痛。然而，此类毛毯对增加深度睡眠、降低血压、增强记忆力、扩张微血管以促进血液流动、减轻慢性炎症以及减轻疲劳的影响仍有待研究。我们旨在研究DAZZEON αSleep远红外毛毯对这些指标的影响。本研究采用双盲设计，招募了24名年龄超过45岁的男性参与者，分为两组，每组12人：（A）安慰剂组和（B）DAZZEON αSleep组。参与者每晚使用该毛毯，为期两周，使用可穿戴设备记录睡眠情况，并在干预前后测量血压、血氧水平、动脉僵硬度和体表温度。采集血样以分析炎症和与睡眠相关的血液指标（血清素和褪黑素），并进行运动测试以评估疲劳改善情况。与干预前相比，该毛毯显著增加了握力和反应时间的变化。此外，它显著增加了血液中血清素、褪黑素和一氧化氮的浓度（<0.05），从而显著增加了深度睡眠和快速眼动睡眠时长（<0.05），并改善了主观睡眠质量（<0.05）。本研究证实，连续14天使用DAZZEON αSleep远红外毛毯有助于改善血液循环、降低血管年龄和动脉僵硬度、提高血清素和褪黑素水平、改善睡眠质量，以及增强肌肉力量和反应时间。
