  • Thermal Stimulation for Assist Awakening Leads to Reduction Effect of Sleep Inertia

抄録

<p>In recent years, lack of sleep has been a serious problem in Japan. Lack of sleep may cause work performance loss. One of the solutions to lack of sleep is napping. Napping has the effect of inhibiting decrease in work performance due to lack of sleep. However, the wrong way of napping may cause sleep inertia on awakening. Sleepinertiaisstrongdrowsinessorheadacheafterawakeningand, leadstoaworkperformanceloss. Inthisstudy, we focused on the relationship between sleep and temperature and, we aimed assisting to awakening with the thermal presentation to reduce sleep inertia. The experimental results suggested that heating thermal stimulation was effective for subjective sleep inertia, while cooling thermal stimulation was effective for objective sleep inertia. However, autonomic nervous activity and Lorenz plot suggested that there were individual differences in sleep state transitions between heating and cooling thermal stimulation.</p>
