摘要

Alcohol intake and sleep deprivation are conditions that cause changes in the physiological status. However, the relationship between biological markers and mood states is not entirely clear yet. The purpose of the study was to compare isolated and combined effects of alcohol intake and sleep deprivation on hormonal and inflammatory responses and in changes in the state of mood. Also, we intended to explain possible changes in mood states through biochemical variations using multiple stepwise regression analysis. Ten healthy male were randomized in four situations: (1) placebo intake + normal sleep (PLA + SLE); (2) alcohol intake + normal sleep (ALC + SLE); (3) placebo intake + sleep deprivation (PLA + SDP); (4) alcohol intake + sleep deprivation (ALC + SDP). While subjects ingested alcohol (1 g/kg of beer), placebo intake was a non-alcoholic beer. The subjects had one night of normal sleep or were subjected to sleep deprivation in the lab for 8 h. After each experimental condition, morning blood samples were taken for assessments of serum levels of glucose, cortisol, testosterone, epinephrine, interleukin-6 (IL-6), interleukin-10 (IL-10) and C-reactive protein (CRP). The subjects were also asked to fill in a Profile of Mood State questionnaire. The results showed that the glucose level was significant lower in ALC + SDP compared to the PLA + SLE condition. Total Mood Disturbance was lower in ALC + SDP and PLA + SDP compared to the PLA + SLE condition. Fatigue was higher under sleep deprivation conditions compared to PLA + SLE. Vigor was lower under the ALC + SDP condition compared to the PLA + SLE condition. Regression analysis showed that Total Mood Disturbance and fatigue under ALC + SDP were associated with changes in the cortisol levels. Our results showed that combined and isolated alcohol intake and one night of sleep deprivation did not change the hormonal and inflammatory responses tested, and the combined effects caused a reduction in the glucose levels. Vigor, fatigue and Total Mood Disturbance were affected by each condition. Furthermore, Total Mood Disturbance and fatigue were possibly explained by changes in the cortisol levels in the combined condition.
