Temporal dissociation between myeloperoxidase (MPO)-modified LDL and MPO elevations during chronic sleep restriction and recovery in healthy young men.

Objectives: Many studies have evaluated the ways in which sleep disturbances may influence inflammation and the possible links of this effect to cardiovascular risk. Our objective was to investigate the effects of chronic sleep restriction and recovery on several blood cardiovascular biomarkers.

Methods And Results: Nine healthy male non-smokers, aged 22-29 years, were admitted to the Sleep Laboratory for 11 days and nights under continuous electroencephalogram polysomnography.

Benefits of napping and an extended duration of recovery sleep on alertness and immune cells after acute sleep restriction.

Understanding the interactions between sleep and the immune system may offer insight into why short sleep duration has been linked to negative health outcomes. We, therefore, investigated the effects of napping and extended recovery sleep after sleep restriction on the immune and inflammatory systems and sleepiness. After a baseline night, healthy young men slept for a 2-h night followed by either a standard 8-h recovery night (n=12), a 30-min nap (at 1 p.

Sleep restriction increases white blood cells, mainly neutrophil count, in young healthy men: a pilot study.

Objectives: This study examines the effects of sleep restricted to four hours for three consecutive nights on blood parameters, known to be associated with cardiovascular risk, in young healthy men.

Material And Methods: Eight young healthy men (age 24.5 +/- 3.

Effects of sleep restriction on cognition in women.

The aim of the present study was to investigate how three nights of sleep restriction affected cognitive functions in young and aged healthy women. Ten young (20-30 years) and ten aged (55-65 years) women participated to the study. After one baseline night (11 pm-07 am), their sleep was restricted to 4h per night (01-05 am) during three nights.

Psychomotor vigilance task performance during total sleep deprivation in young and postmenopausal women.

The objective of this study was to investigate the effects of age on women's performance in the psychomotor vigilance task (PVT) during total sleep deprivation (SD). A total of 46 healthy women volunteered. They belonged to two age groups: young (n=34; age range 19-30 years; 12 without, and 22 with oral contraceptives (OC); early phase of the menstrual cycle) and older (n=12; age range 60-68; postmenopausal; without hormone therapy).

Sleep restriction increases blood neutrophils, total cholesterol and low density lipoprotein cholesterol in postmenopausal women: A preliminary study.

Objectives: This study examines the effects of sleep restricted to 4h for three consecutive nights on blood parameters known to be associated with cardiovascular risk in healthy postmenopausal women.

Material And Methods: Ten healthy postmenopausal women aged 55-65 years treated with hormonal replacement therapy (HT) were included in the study. After one baseline night, three nights of sleep restricted to 4h were performed and were followed by one recovery night of 8h.

Age modulates the effects of sleep restriction in women.

Study Objectives: To investigate how age influences the effects of 3 nights of sleep restriction in healthy women.

Design: After a baseline night, sleep was restricted to 4 hours during 3 consecutive nights. One recovery night followed the sleep restriction.

Women's sleep in health and disease.

A huge amount of knowledge about sleep has accumulated during the last 5 decades following the discovery of rapid eye movement (REM) sleep. Nevertheless, there are numerous areas of considerable ignorance. One of these concerns the particularities of sleep in women.
