Sleep and all that happens in the world of sleep have significant effects on our mind, body, and health. However, in the whirlwind of modern existence, we often cut corners on sleep. In a recent study, researchers studied the profound impact of sleep on the effectiveness of vaccines. Understanding that vaccination is a critical strategy for controlling the pandemic of COVID-19, the researchers looked at how sleep, as a behavioral intervention, can boost vaccine response. The researchers first screened and selected studies for their meta-analysis. They then found a consistent pattern: insufficient sleep duration of <6h, for 7 days around inoculation is significantly associated with a weakened antibody response to vaccination. Vaccines in the study included hepatitis A, hepatitis B, influenza A H1N1 and H3H2, and the effect size was positive, indicating that short sleep is associated with a lower level of antibodies or reduced protection status. These findings underscore the critical role...
