Investigating daytime effects of correlated colour temperature on experiences, performance, and arousal (2017, positive): “…cognitive performance, and physiological arousal during the subjective night (An, Huang, Shimomura, & Katsuura, 2009; Brainard et al., 2015; Cajochen et al., 2011, 2005; Chellappa et al., 2011; Ekstr€om & Beaven, 2014; Figueiro, Bierman, Plitnick, & Rea, 2009; Figueiro, Rea, & Bullough,…”
Adolescents’ Electronic Media Use at Night, Sleep Disturbance, and Depressive Symptoms in the Smartphone Age (2014, background): “LED back light screens emit an increased amount of light in the short wave length spectrum of around 460 nanometers which suppresses melatonin secretion in the evening and reduces subjective and objective signs of sleepiness (Cajochen et al. 2011).”
Adverse physiological and psychological effects of screen time on children and adolescents: Literature review and case study (2018, background): “Thus, the use of mobile devices which allows access to most types of content, and encourages multiscreening (Cain and Gradisar, 2010; Cajochen et al., 2011), is creating a growing concern (Falbe et al.”
Digital eye strain: prevalence, measurement and amelioration (2018, background): “Exposure to short wavelength light (including digital devices) before bedtime can disrupt sleep patterns, 95 96 while use of short wavelength blocking spectacles in the evening can improve sleep duration and quality 97 98 and reduce subjective alertness.”
Identifying Objective Physiological Markers and Modifiable Behaviors for Self-Reported Stress and Mental Health Status Using Wearable Sensors and Mobile Phones: Observational Study (2018, background): “Second, lighting from the interaction with mobile phones or emailing late at night could disturb the biological circadian clock and increase alertness, both of which can influence sleep patterns [27,28].”
