Study: Sleep deprivation can cause heart attack
According to the findings of a study, insufficient sleep is the major reason for the disadvantaged groups to have cardiac issues and heart disease. The results of the study published in the journal Cardiovascular Research. People with lower socioeconomic status remain sleepless for a variety of reasons: they may do several jobs, work in shifts, live in noisy environments, and have greater levels of emotional and financial stress.
This was the first large population-based study to examine whether a lack of sleep could partly explain why poor people have more heart disease. It found that short sleep explained 13.4 percent of the link between occupation and coronary heart disease in men.
Study author Dusan Petrovic, of the University Centre of General Medicine and Public Health (unisante), Lausanne, Switzerland, said: "The absence of mediation by short sleep in women could be due to the weaker relationship between occupation and sleep duration compared to men."
"Women with low socioeconomic status often combine the physical and psychosocial strain of manual, poorly paid jobs with household responsibilities and stress, which negatively affects sleep and its health-restoring effects compared to men," Study author Dusan Petrovic said.
He further said: "Structural reforms are needed at every level of society to enable people to get more sleep. For example, attempting to reduce noise, which is an important source of sleep disturbances, with double glazed windows, limiting traffic, and not building houses next to airports or highways."
