“…The agreement between our study and the isolation studies also extends to the sleep stage patterning SWS is seldom affected by the time of day whereas REM is clearly enhanced during a few hours in the morning. The data thus far agree very satisfactorily with the data from shift work studies and from the laboratory experiment on day sleep by Benoit et al 15. The majority of laboratory experiments, however, have failed to confirm the early termination of day time sleep 16,22,47,5~ The reason for the discrepancy is not clear, but compared to the shiftwork studies and the laboratory experiments done by Benoit et al ~5 and ourselves 3 other laboratory experiments have used much younger subjects as well as a restricted time-in-bed (usually 8 h).…”

“…The similarity of sleep patterns across groups during a recovery night after 36 h of sleep deprivation (Cond. 3) suggests that the need for recovery masks interindividual differences, as previously reported in a study of long and short sleepers (7). In contrast, the recovery sleep for the three groups is clearly differentiated when subjects are required to sleep in the morning after 1 night of sleep deprivation (Cond.…”

Summary: Three groups of young, normal sleepers were selected as morning types (MTs).1 evening types (ETs), and neither types (NTs) as determined by the Horne and Ostberg questionnaire. Sleep and rectal temperatures were recorded under three conditions: baseline nights (Cond. 1), sleep on the recovery day after 1 night of sleep deprivation (Cond. 2), and sleep on the recovery night after I night and 1 day of sleep deprivation (Cond. 3). During Conds. 1 and 3, when sleep schedules were self-determined, sleep structure and body temperature were similar in MTs, and ETs, and NTs. During Condo 2, however, MTs had poorer sleep, i.e., a smaller percentage of REM sleep and more awakenings, than ETs. This difference can be related to the evolution of temperature during Condo 2; i.e., a temperature increase in the MT and NT and a decrease in the ET. Key Words: Human sleep--Morning type-Evening type-Sleep deprivation-Temperature evolution.Classifying individuals as morning types (MTs), evening types (ETs), and neither types (NTs) is based, in addition to everyday observations, on (a) reported sleep schedules (1), (b) subjectively assessed arousal (2,3), and (c) the time of temperature peak (1). Other circadian variables, such as the excretion of catecholamine (norepinephrine) (2), are not significant indicators of type.All studies differentiating MTs from ETs have utilized diurnal measurements. As far as we know, only Webb and Bonnet (4) have studied nocturnal sleep. However, they clearly differentiated only two groups, MTs and ETs, and studied these two groups only in relation to their sleep schedules and the subjective quality of their sleep. Except for the work of Breithaupt et al. (5), few studies have been devoted to the influence of MT/ET typology on sleep when sleep is delayed.The present study investigates the internal sleep structure of MTs and ETs in relation to the temporal evolution of body temperature. METHODSNineteen healthy young subjects (aged from 20 to 26 years) selected by means of a questionnaire (1) participated as paid volunteers. All subjects were satisfied with both their sleep and diurnal vigilance and had agreed to keep a 2-week sleep log.

. It is found in coffee, of course, but also in tea, chocolate-flavored products and cola-based beverages, etc. 1 Due to its behavioral and psychomotor stimulating properties, it is used to maintain vigilance, memory, and performance levels during limited sleep deprivation. [2][3][4][5][6][7][8] Some prolonged sleep deprivation and wake-sleep rhythm disruptions are common in everyday life, especially in emergency cases, during rescue operations, in the army, or during transmeridian flights. These situations lead to a certain number of vigilance and performance alterations, which in turn lead to a decrease in efficacy or to the onset of penalizing symptomatology. [9][10][11][12] However, the results obtained with the use of caffeine to increase vigilance and performance level vary greatly. Sometimes, the results are very positive; an increase in performance mainly in visual vigilance tasks 13 can be observed as well as an increase in the level of awakeness-measured by electrophysiological techniques 2 -for unusual situations such as night work. Other studies reported an absence of effects or heterogeneous results 14 and sometimes negative effects such as the onset of tolerance during repeated intake of caffeine 15 or the onset of anxiety with still relatively low doses (325 mg). 16 In a general way, all the studies selected from a bibliographic research report an unquestionable stimulating and awaking effect of caffeine, but the effect has a limited power-especially compared with amphetamine-and duration. 17,18 Moreover, repeated caffeine intake can lead to the onset of deleterious cardiovascular or neurological side effects when the dose exceeds 600 mg. Therefore, it seemed interesting to assess the effects of a new galenic form of caffeine called " slowrelease " caffeine (SR caffeine) Stinergic. The release of Study Objectives: The aim of this study is to assess the interest of the intake of a new galenic form of caffeine called " slowrelease " caffeine (SR caffeine) during a decrease of vigilance due to a limited sleep deprivation. Design: The controlled method used compared three doses of SR caffeine (150, 300 and 600 mg) with a placebo. Tests were performed 2, 9 and 13 hours after each treatment. Wakefulness level was assessed subjectively through questionnaires and analog visual scales, and objectively with the Multiple Sleep Latency Test. Performance level was also assessed regularly with an attention test, a grammatical reasoning test, a spatial recognition test, a mathematical processing test, a visual tracking test, a memory search test, and a dual task. The motor activity was evaluated by wrist actimeter and safety of treatment was observed by regular clinical examination. Setting: NA Participants: Twenty-four young and healthy volunteers (12 men and 12 women) participated in a 32-hour sleep deprivation. Interventions: NA Results: The results show a significant effect of slow-release caffeine vs. placebo, and on vigilance and performance when subjects became tired. The effects of SR caffeine lasted 13...
