Scientists have discovered that poor sleep can make the brain age nearly three years faster, according to a new study. This research, involving almost 600 middle-aged participants, revealed that difficulties in falling asleep or staying asleep are linked to lower brain health in later years.
The study took place over five years, with participants sharing their sleep experiences at the start and again after five years. Researchers focused on six key sleep issues: short sleep duration, low sleep quality, trouble falling asleep, trouble staying asleep, waking up early, and daytime drowsiness.
Participants were divided into three groups based on the number of sleep problems they reported. Those with the least issues had one or none, while those with the most serious issues reported more than three, according to The Independent.
Importance of Addressing Sleep Issues
After 15 years, brain scans showed that individuals with ongoing sleep problems experienced more significant brain aging. Kristine Yaffe, a leading scientist from the University of California, highlighted that these findings stress the need to tackle sleep problems early to help maintain brain health.
She emphasized the importance of keeping a consistent sleep schedule, exercising, and practicing relaxation techniques. Although the study found a strong connection between poor sleep and brain aging, it did not confirm that one directly causes the other.
Dr. Shelby Harris, a clinical psychologist, pointed out that accelerated brain aging can lead to serious problems like memory loss and even diseases such as dementia. She stated that when the brain ages prematurely, it can cause difficulties in everyday tasks and affect mental clarity, which impacts quality of life.
Another expert, Dr. Fouzia Siddiqui, mentioned that brain aging could also lead to mood changes, such as irritability and problems with attention. To improve sleep quality, experts recommend prioritizing sleep by ensuring enough sleep hours and creating a restful sleeping environment.
Avoiding screens before bed and developing calming activities like breathing exercises or meditation can also be beneficial. Harris suggests establishing a regular sleep schedule and reducing caffeine and alcohol intake before bedtime.
If someone struggles with sleep despite making these changes for two weeks, it's important to consult a doctor for further evaluation and treatment.
