A new study has just revealed the ideal sleep duration for a healthy brain.
Sleep is very important to health. Moreover, a new Fino-British study, the results of which have just been published In Nature Aging just revealed The perfect bedtime For the best possible brain.
What is the ideal period of sleep for a healthy brain?
To get to the point of determining the bedtime needed for brain health, Christelle Langley, of the Department of Psychiatry at the University of Cambridge (United kingdom) and researchers from Fudan University (China) analyzed data from the UK Biobank for nearly 500,000 people aged 38 to 73. They were questioned about their sleeping habits, mental health and safety. Moreover, 40,000 people provided brain imaging data and genetic data.
Thus the results show that after the age of 40, the optimal sleep duration is 7 hours. We also learn that shorter sleep time was directly related to poorer cognitive performance, such as faster information processing, memory, problem-solving ability, and visual attention. In the case of longer sleep, the researchers revealed that it was associated with more frequent symptoms of anxiety and depression, but it also led to lower well-being.
Of course, this ideal period of sleep 7 hours means sleep in good conditions. Nighttime awakenings, for example, can affect the optimal efficiency of the brain. The researchers also add that the results show The importance of having a regular sleep pattern.
The researchers then concluded: “7 hours of sleep per night is the optimal amount for maintaining good cognitive performance. Therefore, finding ways to improve sleep in older adults can be crucial in helping them maintain good mental health and avoid cognitive decline, especially for patients who suffer from mental disorders and dementia.” According to them, the association between insufficient sleep and cognitive decline is caused by a deep sleep disorder.
