“…Afferents including receptors activated by WAS were unclear. However, several reports have shown that local warming at about 40°C applied to lumbar or abdominal regions induced pleasant sensations [9,24]. Rolls showed that warming the hand of subjects at 41°C brought about a pleasant emotion and induced a significant neural activation in the orbito-frontal cortex, pregenual cingulated cortex and ventral striatum [25].…”

Objective: People generally use a mask to prevent inhaling or exhaling fine particles or bacteria. However, it hinders breathing to some extent and causes an unpleasant feeling. Therefore, it is necessary to improve the material of mask. Methods: In this study, in 14 healthy male subjects we examined the effect and sensation or impression of aroma sheets (A), warm-steam sheets (WS) and warm-steam-aroma sheets (WSA) set in a mask. Respiratory rate (RR), State-Trait Anxiety Inventory (STAI) and visual analogue scale (VAS) for different feelings were analyzed during the application of a mask with (WS), (A) or (WSA) and compared with the results without such sheets. Results: RR and state anxiety scores were decreased during the wearing of the masks. Differences in RR and state anxiety score showed a significantly linear positive correlation during WSA. Feelings of calmness, renewed energy, relaxation and good feeling were significantly increased during WSA. Conclusion: The results suggest that warm-steam-aroma sheet is a useful material to set inside a mask to decreasing anxiety and increasing pleasant feelings.

“…A previous study reported that mood states such as happy and angry were correlated with autonomic nervous activity (Kop et al., ). Furthermore, application of the same HSG sheet increased feelings of comfort with increased parasympathetic nervous activity (Nagashima et al., ). These results suggest that alteration of emotional states during thermal stimulation might change autonomic nervous activity.…”

To investigate neural mechanisms of local thermotherapy to reduce mental stress, participants were required to perform mental arithmetic after treatment by a heat- and steam-generating sheet on the facial eyelid region while hemodynamic activity and ECGs were monitored. The results indicated that thermotherapy decreased hemodynamic activity in the anterior dorsomedial prefrontal cortex (aDMPFC) involved in sympathetic activity. Consistently, thermotherapy increased parasympathetic activity while it decreased sympathetic activity. Furthermore, thermotherapy increased hemodynamic activity in the dorsolateral prefrontal cortex (DLPFC) during mental arithmetic. These hemodynamic responses in the DLPFC during mental arithmetic were negatively correlated with that in the aDMPFC during thermotherapy. The results suggest that thermotherapy in the facial eyelid region is useful to ameliorate mental fatigue through its effects on the prefrontal cortex.

“…Recently, we have developed a disposable heat- and steam-generating (HSG) sheet that safely and easily warms the periocular, abdominal, or lumbar skin and reported that it is able to reduce sympathetic and increase parasympathetic nerve activity [ 6 , 7 ], as well as enhancing alpha-band electroencephalogram activity [ 8 ], leading to potential relaxation of somatic arousal.…”

Several studies have reported that suitable manipulation of human skin or body temperature can lead to improved sleep. To clarify the effect of skin warming on human sleep, 38 female subjects, who occasionally had difficulty with falling asleep, were studied. The participants underwent two experimental sessions, which were carried out in two consecutive follicular phases and randomly crossed over. The participants wore hot or sham eye masks in one 14-day session. The first half of each 14-day session was designated the baseline period (BL) without any interventions and the later half was designated the intervention period (INT), in which they wore either the hot or sham eye mask for 10 minutes at bedtime. All the participants were instructed to keep a sleep diary every morning for the BL and INT. The results showed that the hot eye mask was significantly preferred over the sham one with respect to comfort and that feelings of restfulness and being refreshed upon wakening in the morning were significantly better with the hot eye mask than with the sham. These results suggest that bedtime periocular warming has favorable effects on subjective well-being on awakening, possibly due to the sense of comfort experienced at bedtime.
