Afternoon napping promotes cognitive function in the elderly: Study

Among all the subjects, 739 elderly volunteered to take blood lipid tests.

The results of the study are as follows:

• Significant differences in cognitive function and blood lipids were observed between the napping and the non-napping groups.
• Afternoon napping was associated with better cognitive function including orientation, language, and memory in the present study.
• Subjects with the habit of afternoon napping also showed a higher level of triglyceride than the non-napping subjects.
• Through this prospective intervention study, both habitual and non-habitual nappers performed better on long-term memory tasks after an afternoon nap as compared to controls.
• Habitual nappers demonstrated improved performance on both short and long-term memory tasks following an afternoon nap as compared to those who remained awake

The researchers concluded that as per the results afternoon napping was related to better cognitive function in the Chinese ageing population.
