Each 1-hour increase in sleep associated with 12% lower odds of infection among clinicians
Insomnia, disrupted sleep, and daily burnout are linked to a heightened risk of not only becoming infected with coronavirus, but also having more severe disease and a longer recovery period, suggests an international study of healthcare workers, published in the online journal BMJ Nutrition, Prevention & Health.
Every 1-hour increase in the amount of time spent asleep at night was associated with 12% lower odds of becoming infected with COVID-19, the findings indicate.
Disrupted/insufficient sleep and work burnout have been linked to a heightened risk of viral and bacterial infections, but it’s not clear if these are also risk factors for COVID-19, say the researchers.
To explore this further, they drew on the responses to an online survey for healthcare workers repeatedly exposed to patients with COVID-19 infection, such as those working in emergency or intensive care, and so at heightened risk of becoming infected themselves.
