Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. Identify obstacles to healthy sleep patterns in NUS staff 1.1) How do staff sleep, in terms of duration, timing, regularity and napping behaviour? 1.2) What is the gulf between sleep aspiration and attained sleep? 1.3) What are self-perceived obstacles to achieving better sleep? 1.4) What activities potentially displace time for sleep?
2. Understand inter-relationships between sleep, workplace stressors and wellbeing outcomes 2.1) How is sleep is modulated over the year? 2.2) How do work patterns (e.g., after-hours/vacation emails) correlate with sleep, physical activity, subjective wellbeing, physiological markers of stress? 2.3) How do work, social, status stress and other life events contribute to sleep, wellbeing and subjective perceptions of work productivity?
3. Examine the association between sleep, workplace stress, mental health, cardiovascular risks in middle-aged cohort 3.1) How do daily sleep, work place events and acute/chronic stress contribute to cardiovascular health atmiddle age? 3.2) How is subjective wellbeing associated with objective cardiovascular wellbeing?
4. Examine the effects of any structural organizational efforts to promote wellbeing on staff sleep and stress
The investigators hypothesize that acute stressors, such as receiving emails after office hours and during vacation periods, will negatively impact sleep duration and regularity, as well as subjective stress rating over a short period. Chronic stressors, such as family care burden and pressure from supervisor, will be associated with longer-term insufficient and irregular sleep. Staff members reporting high chronic stress and frequent acute stress may be more likely to have high cardiovascular and cerebrovascular risks. In general, irregular/short sleep, constant high subjective stress, and frequent routine disruption (i.e., after hours work) will be associated with high cardiovascular risk in middle-aged participants.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
Exclusion Criteria
1. Have their sleep and physical activity rhythms recorded via wearable sensors, while they continue daily life as usual.
2. Complete periodic questionnaires and short daily surveys on their smartphones.
3. Agree to interactions with their smartphones and NUS e-services (e.g., email) tracked.
Participants who do not agree to have these measures recorded will not be eligible for the study. Shift workers (e.g., security personnel, doctors and nurses), nursing/pregnant woman, and patients with existing sleep/psychological disorders (e.g., insomnia and major depression) will also be excluded.
