Importance Light at night causes circadian disruption, which is a known risk factor for adverse cardiovascular outcomes. However, it is not well understood whether personal light exposure patterns predicts and individual’s risk of cardiovascular diseases.Objective To assess whether day and night light exposure predicts incidence of cardiovascular diseases, and whether relationships of light with cardiovascular… Continue reading Personal night #light exposure predicts incidence of #cardiovascular diseases in >88,000 individuals

#Sleep duration, chronotype, #health and lifestyle factors affect cognition: a UK Biobank cross-sectional study
Objective To explore the nuanced relationship between sleep patterns, chronotype, quality and the influence of health and lifestyle factors on cognitive performance.Design, setting, participants This cross-sectional analysis used ordinary least squares regression within the UK Biobank database, assessing 26 820 participants aged 53–86 years, categorised into two cohorts: Cohort 1 (10 067 participants, 56% female; completed all four… Continue reading #Sleep duration, chronotype, #health and lifestyle factors affect cognition: a UK Biobank cross-sectional study
Long-term night #shift work is associated with the risk of atrial #fibrillation and #coronary heart disease
The aim of this study was to test whether current and past night shift work was associated with incident atrial fibrillation (AF) and whether this association was modified by genetic vulnerability. Its associations with coronary heart disease (CHD), stroke, and heart failure (HF) were measured as a secondary aim. Methods and resultsThis cohort study included… Continue reading Long-term night #shift work is associated with the risk of atrial #fibrillation and #coronary heart disease
#Metabolic responses to polychromatic #LED and #OLED light at night
Light exposure at night has various implications for human health, but little is known about its effects on energy metabolism during subsequent sleep. We investigated the effects of polychromatic white light using conventional light-emitting diodes (LED) and an alternative light source, organic light-emitting diodes (OLED), producing reduced spectral content in the short wavelength of blue… Continue reading #Metabolic responses to polychromatic #LED and #OLED light at night
Bedtime hypertension treatment improves #cardiovascular risk reduction: the Hygia Chronotherapy Trial
In this multicentre, controlled, prospective endpoint trial, 19 084 hypertensive patients (10 614 men/8470 women, 60.5 ± 13.7 years of age) were assigned (1:1) to ingest the entire daily dose of ≥1 hypertension medications at bedtime (n = 9552) or all of them upon awakening (n = 9532) ..Patients of the bedtime, compared with the upon-waking, treatment-time regimen showed significantly lower hazard… Continue reading Bedtime hypertension treatment improves #cardiovascular risk reduction: the Hygia Chronotherapy Trial
