“…In this prospective cohort study, no evidence of an association between self-reported physical activity or self-reported sleep habits and the incidence of URTI was found. Our null result on physical activity agrees with some previous studies, including a Cochrane systematic review published in 2015, [ 11 ] but it disagrees with several observational studies reporting inverse associations between moderate physical activity and URTI incidence [ 5 – 9 ].…”

“…Several other studies have reported similar inverse associations [ 7 – 9 ]. In contrast, a large cohort study in Finland did not find an association between physical activity and the risk of common cold, [ 10 ] neither did a recent Cochrane systematic review of 11 trials [ 11 ]. Previous studies have been criticised for their lack of validated methods for measuring incidence of URTI and insufficient control of confounding [ 5 , 6 , 12 ].…”

Physical activity, sleep and risk of respiratory infections: A Swedish cohort study

ObjectivesPrevious studies found higher levels of physical activity to be protective against infections and that short and long sleep negatively affects the immune response. However, these relationships remain debatable. We aimed to investigate if physical activity and sleep habits affect incidence of upper respiratory tract infections (URTI) in a prospective cohort study.MethodsA total of 2,038 adults aged 25–64 years served as a random sample of the gainfully employed population of an industrial town in Sweden. Physical activity and sleep habits were estimated through self-reported questionnaires. Physical activity was expressed as metabolic energy turnover hours per day. Sleep was assessed as number of hours slept per night and its perceived quality. URTI outcome was prospectively self-reported during a 9-month follow-up period. Associations of physical activity and sleep with URTI were estimated using hurdle regression models adjusted for potential confounders.ResultsDuring 1,583 person-years 1,597 URTI occurred, resulting in an incidence of 1.01 infections/person-year (95% CI 0.96–1.06). The fitted regression models did not provide support for an association with physical activity or sleep habits. Factors positively associated with experiencing URTI were having children ≤ 6 years, female gender, higher education and treatment for allergy, asthma or lung cancer. Having children ≤ 6 years and female gender were related to a higher number of URTI among those experiencing URTI.ConclusionsWe did not find any association between physical activity, sleep duration or sleep quality and the occurrence of upper respiratory tract infections in adult Swedish population.

“…For example, people with higher levels of perceived stress [5][6][7][8], emotional reactivity [9], recent stressful life events [10,11], and negative emotional styles [12,13] are at greater risk for ARI illness. Numerous observational studies and a few small randomized trials suggest that exercise helps prevent ARI illness [14][15][16].…”

BackgroundPractice of meditation or exercise may enhance health to protect against acute infectious illness.ObjectiveTo assess preventive effects of meditation and exercise on acute respiratory infection (ARI) illness.DesignRandomized controlled prevention trial with three parallel groups.SettingMadison, Wisconsin, USA.ParticipantsCommunity-recruited adults who did not regularly exercise or meditate.Methods1) 8-week behavioral training in mindfulness-based stress reduction (MBSR); 2) matched 8-week training in moderate intensity sustained exercise (EX); or 3) observational waitlist control. Training classes occurred in September and October, with weekly ARI surveillance through May. Incidence, duration, and area-under-curve ARI global severity were measured using daily reports on the WURSS-24 during ARI illness. Viruses were identified multiplex PCR. Absenteeism, health care utilization, and psychosocial health self-report assessments were also employed.ResultsOf 413 participants randomized, 390 completed the trial. In the MBSR group, 74 experienced 112 ARI episodes with 1045 days of ARI illness. Among exercisers, 84 had 120 episodes totaling 1010 illness days. Eighty-two of the controls had 134 episodes with 1210 days of ARI illness. Mean global severity was 315 for MBSR (95% confidence interval 244, 386), 256 (193, 318) for EX, and 336 (268, 403) for controls. A prespecified multivariate zero-inflated regression model suggested reduced incidence for MBSR (p = 0.036) and lower global severity for EX (p = 0.042), compared to control, not quite attaining the p<0.025 prespecified cut-off for null hypothesis rejection. There were 73 ARI-related missed-work days and 22 ARI-related health care visits in the MBSR group, 82 days and 21 visits for exercisers, and 105 days and 24 visits among controls. Viruses were identified in 63 ARI episodes in the MBSR group, compared to 64 for EX and 72 for control. Statistically significant (p<0.05) improvements in general mental health, self-efficacy, mindful attention, sleep quality, perceived stress, and depressive symptoms were observed in the MBSR and/or EX groups, compared to control.ConclusionsTraining in mindfulness meditation or exercise may help protect against ARI illness.LimitationsThis trial was likely underpowered.Trial registrationClinicaltrials.gov NCT01654289

“…However, an association between physical activity and ILI/ARI incidence rate, and thus the association between mediator and outcome, was lacking. Correspondingly, a Cochrane systematic review did not find an association between moderate-intense physical activity and ARI (40). Diet (ie, number of meals and snacks) also did not mediate the association between shift work and ILI/ARI incidence rate.…”

The mediating role of sleep, physical activity, and diet in the association between shift work and respiratory infections by Loef B, van der Beek AJ, Hulsegge G, van Baarle D, Proper KI In this study among healthcare workers, the association between shift work and an increased incidence rate of respiratory infection episodes was mediated by poorer perceived sleep quality among shift workers. To prevent respiratory infections in shift workers, it may therefore be relevant for future intervention research to focus on strategies to improve perceived sleep quality.
