US: association between pesticide exposure and sleep health

Those with insomnia complain of not being able to fall asleep or sleep only for a few minutes, fidgeting in bed at night. If insomnia lasts for more than a few nights in a row it can become chronic and cause a sleep debt that is extremely harmful to the insomniac's health.

Insomnia alters the natural sleep cycle, which can be difficult to restore. Some insomniacs try to sleep in the afternoon or during the evening, resulting in being very alert at bedtime, aggravating insomnia. Often, unknowingly, the body is pushed to the limit, to the point where sleep deprivation causes severe physical and mental problems.

This is associated with daytime dysfunction, with symptoms such as fatigue, irritability, learning difficulties, non-consolidation of memory, and a marked loss of interest in carrying out daily activities. All of this has a considerable psychological impact.

Its opposite polarity is hypersomnia. The study Association between pesticide exposure and sleep health among a representative sample of US adults: evidence from NHANES 2009-2014, published on the BMC public health, makes an interesting retrospective on the subject, studying over a period of time a sample of patients in US.

The researchers explain: "Data suggest that pesticides interact with the melatonin receptor, which may influence sleep. However, the link between pesticides and sleep remains unexplored among the general adult population.

This study evaluated unstratified and sex-stratified associations between urinary pesticide exposure and self-reported acute household pesticide exposure, with sleep health outcomes within a nationally representative sample of US adults.

Data from the National Health and Nutrition Examination Surveys (NHANES) 2009-2014 were combined for analysis of aim 1 and aim 2. Urinary pesticide metabolite concentrations served as biomarkers of pesticide exposure. Acute household pesticide exposure, if any chemical products were used in the home in the past seven days to control pests, was self-reported.

Insufficient sleep duration and trouble sleeping that accounted for complex survey weights and adjusted for confounders were used to compute prevalence ratios and 95% CI. Log urinary 3-phenoxybenzoic acid (3-PBA) was related to a higher probability of insufficient sleep and trouble sleeping among males.

Self-reported acute household pesticide exposure was associated with a higher probability of insufficient sleep duration and trouble sleeping in the unstratified sample. Gender-stratified findings showed that associations between acute household pesticide exposure and trouble sleeping only persisted among males. In summary, acute pesticide exposure may be detrimental to adult sleep health, particularly among US males."
