nighttime Brain Chemistry Linked to increased Sadness, Anxiety – and how to Reclaim Peaceful Sleep
PARIS – A growing body of research reveals a biological basis for why dark thoughts often surface at night, with a shift in brain chemistry making individuals more vulnerable to sadness, nostalgia, and anxiety during evening hours. A recent 2023 study by the National Institute of Sleep and Vigilance (INSV) and Public Health France found that nearly 45% of French people go to bed after midnight at least three times a week, correlating with a 30% increase in depressive and anxiety symptoms among those under 35.Understanding this connection is crucial, as prioritizing nighttime rest isn’t simply about sleep quality – it’s about protecting mental wellbeing.
During the night, the brain’s production of melatonin increases while serotonin levels – a key neurotransmitter involved in mood regulation – decrease. This neurochemical shift creates a biological predisposition towards more negative emotional states. Researchers emphasize this isn’t a reason to fear the night, but a signal to actively protect mental health by establishing routines that support serenity.
How to Find Peaceful Nights
Experts recommend several adjustments to preserve mental wellbeing during nighttime hours. These include maintaining consistent sleep schedules, disconnecting from screens at least an hour before bed, and creating a calming, dark sleep environment. Avoiding stimulants in the evening is also advised. Recognizing that the emergence of dark thoughts at night is a biological signal – a demand for serenity from the brain – is a critical first step.
NAMELY
according to research carried out by the National Institute of Sleep and Vigilance (INSV) and Public Health France in 2023, nearly 45% of French people say they go to bed after midnight at least three times a week, frequently enough due to screens or working late. This nocturnal rhythm is accompanied by a 30% increase in depressive and anxiety symptoms among those under 35.
