SWithout good sleep the brain suffers and ages faster. This is demonstrated by a study of UK Biobank: researchers analyzed sleep habits and long-term brain health of 27,500 adults Between Sweden and Chinacombining data on sleep patterns and brain scans. The result? Snoring, being a night owl, or sleeping less than seven hours a night contributes to an acceleration of brain ageincreasing the future risk of cognitive decline and dementia.
The nocturnal habits that hurt the brain the most
The researchers have identified five nocturnal behaviors that affect brain aging:
Go and bed late– those who tend to stay up late are more likely to have an older brain.
Insomnia – difficulty falling asleep or staying asleep disrupts regenerative brain cycles.
Snore – symptom of sleep apnea or breathing difficulties that reduce the quality of sleep.
Sleep less than seven hours a night – sleep deprivation damages memory, concentration and cognitive functions.
Excessive daytime sleepiness – an indicator of unrestful sleep, which impairs brain performance.
Research shows that sleeping poorly makes the brain age fasterAlso of several monthsand who is above all guiding this process chronic inflammation caused by unhealthy sleeping habits.

In addition to tiredness, poor concentration and bad mood, bad habits related to sleep can accelerate brain aging. Why? According to researchers, it plays a key role systemic inflammation. Sleeping little or poorly can raise the levels of inflammatory substances in the body, which over time damage brain cells and accelerate cognitive decline, increasing the risk of Alzheimer’s and other forms of dementia.. In the study, inflammation explained about the 7-10% of the association between poor sleep habits and increased brain age.
