Recuperation of sleep time associated with a better diet and low alcohol consumption

Good recovery from sleep time is associated with healthy diet and eating habits, as well as low alcohol consumption, new study examining psychological and physiological well-being of Finnish adults finds of working age.

The association of physiological recovery and nutrition has only been very little studied. Posted in Journal of Occupational Medicine and Toxicology, a new study is now examining whether physiological recovery during sleep is related to eating behavior and diet quality.

The study population consisted of 252 psychologically distressed overweight adults who participated in a lifestyle intervention study in three Finnish cities. Their recovery was measured based on the variability in heart rate during sleep recorded over three consecutive nights. Heart rate variability was used to measure both parasympathetic and sympathetic activation of the autonomic nervous system, and their relationship, i.e. the balance between stress and recovery. The parasympathetic nervous system plays a key role in recovery, during which the heart rate is decreased and the heart rate variability is high.

The eating behavior of study participants was measured using four different questionnaires, and the quality of their diet and alcohol consumption was quantified using two different questionnaires and a dietary reminder. 48 hours. The aim was to explore the association between physiological recovery, diet quality, alcohol consumption and different aspects of eating behavior, such as eating according to hunger and satiety signals. The present results come from data collected at baseline before the lifestyle intervention.

According to the study, higher parasympathetic activity during sleep, which indicates better physiological recovery, is associated with a more health-friendly quality of diet and lower alcohol consumption, and possibly also with eating habits, especially factors affecting our decision to eat. In particular, participants with a good stress balance reported better overall diet quality, higher fiber intake, greater dietary self-control, and lower alcohol consumption than those with a poorer diet. stress balance.

However, the researchers point out that the design of the cross-sectional study does not allow any causal conclusion. In other words, one cannot conclude from the results whether better recovery leads to healthier eating or whether healthy eating promotes better recovery.
