Numerous studies have demonstrated an association between sleep disturbances and weight gain, and more specifically, that sleep deprivation is related to overweight.[1] Furthermore, body weight also influences the quality of sleep and the occurrence of sleep disorders like obstructive sleep apnea.[2] Oversleeping may also contribute to weight gain.[3]
Additionally, there is a decrease in sleep duration and quality among most populations due to modern lifestyles which include an increased time spent looking at artificial lights from screens.[4][5] The availability of night-time use of electronic devices and communication devices are associated with shorter sleep duration and increased body weight in children.[5]
