Mood impairment is stronger in young than in older adults after sleep deprivation

Abstract

Sleep deprivation commonly impairs affective regulation and causes worse mood. However, the majority of previous research concerns young adults. Because susceptibility to sleep deprivation and emotion regulation change distinctively across adult age, we tested here the hypothesis that the effect of sleep deprivation on mood is stronger in young than in older adults. In an experimental design, young (18–30 years) and older adults (60–72 years) participated in either a sleep control (young, n = 63; older, n = 47) or a total sleep deprivation condition (young, n = 61; older, n = 47). Sleepiness, mood and common symptoms of sleep deprivation were measured using established questionnaires and ratings. Sleep‐deprived participants felt more sleepy, stressed and cold, and reported lower vigour and positive affect, regardless of age. All the other outcome measures (negative affect, depression, confusion, tension, anger, fatigue, total mood disturbance, hunger, cognitive attenuation, irritability) showed a weaker response to sleep deprivation in the older group, as indicated by age*sleep deprivation interactions (ps < 0.05). The results show that older adults are emotionally less affected by sleep deprivation than young adults. This tolerance was mainly related to an attenuated increase in negative mood. This could possibly be related to the well‐known positivity effect, which suggests that older adults prioritize regulating their emotions to optimize well‐being. The results also highlight that caution is warranted when generalizing results from sleep deprivation studies across the adult lifespan.

Inter-correlations Among Clinical, Metabolic, and Biochemical Parameters and Their Predictive Value in Healthy and Overtrained Male Athletes: The EROS-CORRELATIONS Study

“…In the EROS study, although sleep duration did not have a role in psychological function, unlike previous studies, that strongly correlated sleep duration with mood states (49,55,56). Sleep quality was strongly correlated with better psychological outcomes, including lower depression and fatigue, and higher vigor, indicating that sleep quality led to a global improvement in mood, similarly to what has been unanimously observed (49,55,(57)(58)(59). We speculate that sleep duration was not demonstrated to a major factor of mood states or any other characteristic in athletes because in higher quality sleep duration tends to play a less important role (60,61).…”

The importance of cardiorespiratory fitness and sleep duration in early CVD prevention. BMI, resting heart rate and questions about sleep patterns are suggested in risk assessment of young adults, 18-25 years.

“…The majority of reviews support the conclusion by Nielsen, et al that a short sleep duration consistently is associated with development of obesity in children and young adults, but not consistently so in older adults (7). It has also been shown that sleep deprivation has a stronger effect on mood impairment in young adults compared to in older adults (10) making it an important factor for the well-being of a young adult person.…”

Efeito da rotação dos turnos de trabalho sobre o desempenho psicomotor: um estudo prospectivo e observacional sob condições de vida real

“…Estudos apontam para diversos prejuízos à saúde decorrentes do trabalho em turnos, tais como o aumento de peso corporal (MCHILL et al, 2014) e obesidade (TAHERI et al, 2004 (TSAI et.al., 2017) (COVASSIN et al, 2016) (MACAGNAN et al, 2012, a deterioração do padrão de sono (KECKLUND; AXELSSON, 2016) (HULSEGEE et al, 2018) (BASNER; DINGES, 2011) (SHORT et al, 2015) e o desalinhamento circadiano . Evidências recentes demonstram ainda que o trabalho em turnos está associados a prejuízos no desempenho psicomotor, tais como a queda na atenção (BASNER et al, 2017), perda de memória (RAVEN et al, 2018), vagarosidade na "tomada de decisão" (BROWN et al, 2012), prejuízos no humor (SCHWARZ et al, 2018), problemas psíquicos, motores, sociais e familiares, além de absenteísmo e maior risco de acidentes (RAJARATNAM, 2011) (FERGUSON et al, 2012). Até o momento não há um consenso sobre qual programa de turnos teria um menor impacto na saúde e no desempenho psicomotor, e questões referentes à melhor velocidade para rotação dos turnos (rotações rápidas ou lentas), o melhor sentido da rotação (horário ou anti-horário) (SALLINEN; KECKLUND, 2018), tipo de turno e sequência mais nociva ao desempenho (VEDAAAB et al, 2015) continuam sem respostas.…”

“…Recent evidence demonstrates that shift work is related to negative effects on psychomotor performance (Fisk et al, 2018) which is defined as the ability to maintain and process information for decision making in the workplace (Marek et al,2010). These negative effects include cognitive impairments such as attention drop (Basner et al, 2017), memory (Raven et al, 2017), decision making (Brown et al, 2012), mood alteration (Schwarz et al, 2018), psychic, motor, social and family problems, as well as absenteeism and increased risk of accidents (Rajaratnam et al, 2011) (Ferguson et al, 2012). One of the main triggers for such impairments appears to be deterioration of the sleep pattern (Hulsegee et al, 2015) .…”

“…Dessa maneira, o desalinhamento gerado pelos ritmos circadianos e horários de trabalho impactam negativamente na qualidade e eficiência do sono. Sabe-se que a privação do sono pode trazer graves consequências para o trabalhador, como dores de cabeça, efeitos negativos na performance psicomotora(FISK et al, 2018), queda na atenção(BASNER et al, 2017), memória (RAVEN et al, 2018, prejuízos na tomada de decisão(BROWN et al, 2012), no humor(SCHWARZ et al, 2018), problemasKANTERMANN et al, 2010) (TUCKER et al, 2000. Outros estudos apontam também que turnos noturnos consecutivos elevam o risco de acidentes de trabalho em comparação com o primeiro dia de trabalho da escala) (ORIYAMA; MIYAKOSHI, 2018) e que a longa duração do turno pode impactar na sonolência e fadiga dos trabalhadores(MA et al, 2017).…”
