Jakarta – New research indicates that both regular short sleep and regular excessive sleep are associated with distinct health implications. The study, examining the influence of short sleep and long sleeping habits on brain function, reveals critical insights into the relationship between sleep duration and overall well-being. Researchers analyzed data from nearly half a million adults aged 38 to 73 years from the BIOBank UK database, assessing their sleep hours and correlating them with genetic data, brain images, and overall health examination results. The findings suggest that consistently short sleep is linked to depression and depreciation of the brain in the emotional area.

The research, led by Professor Jianfeng Feng of Warwick University, suggests that consistently short sleep is linked to depression and depreciation of the brain in the emotional area. Conversely, regularly sleeping too long could be an early warning sign of cognitive decline, Alzheimer’s disease, or even schizophrenia. This research underscores the complex relationship between sleep and health, highlighting the need for personalized approaches to sleep management.

The Impact of Short Sleep

The study categorized participants into two groups: those with short sleep (less than seven hours) and those with long sleep (more than seven hours). The analysis revealed that short sleep duration is associated with psychological problems, including bad moods and fatigue, as well as compromised muscle and frame health. Brain scans of individuals with short sleep duration showed a reduction in brain material in areas involved in emotions, increasing the risk of conditions such as depression, heart disease, and obesity.

These findings emphasize the importance of adequate sleep for maintaining emotional stability and physical health.the reduction in brain material in emotion-related areas highlights the potential long-term consequences of chronic sleep deprivation.

the Risks of Excessive Sleep

While short sleep poses important risks, the study also found that sleeping too long regularly is not without its own set of concerns. Excessive sleep is associated with cognitive decline, higher inflammation, and worse metabolic health, including reduced levels of “good” cholesterol.Brain scans indicated a loss of brain material in areas associated with memory and risk areas known for degenerative diseases such as Alzheimer’s and Schizophrenia.

However, the researchers noted a crucial distinction: long sleep duration appears to be a symptom, rather than the cause, of these conditions.This suggests that underlying health issues might possibly be contributing to the need for excessive sleep, rather than the sleep itself directly causing the problems.

Expert Insights

Professor Jianfeng Feng, the study leader, emphasized the importance of these findings, stating:

This study shows a paradigm shift in the way we understand the relationship between sleep and health.

Methodology and Data Analysis

To determine the connection between sleep and brain conditions, researchers analyzed data from nearly half a million adults aged 38 to 73 years from the BIOBank UK database. Participants were asked about their sleep hours in a day and afterward divided into groups based on whether they experienced short sleep (less than seven hours) or long sleep (more than seven hours).

The researchers then analyzed genetic data, brain images, and overall health examination results to understand how the duration of sleep can affect brain function and cognitive health in the long run. This thorough approach allowed them to identify distinct patterns and associations between sleep duration and various health outcomes.

Implications for Future Research

The researchers emphasize that long sleep and short sleep are two “different biological” processes with each genetic association. This understanding is crucial for developing targeted interventions and personalized approaches to sleep management.

Professor Feng outlined the future goals of their research:

Our main goal is to build a comprehensive sleep health profile throughout the range of human life, providing insights that can be followed up for individuals at every stage of life.
