Taking a short nap during the day can enhance memories of disturbing and fearful events, a new study reports.
Study reveals a bi-directional link between daytime napping and cognitive decline associated with Alzheimer's disease. Researchers say longer, more frequent napping was associated with worse cognition after one year, and worse cognition was linked to longer and more frequent daytime naps.
How often a person takes a daytime nap, or whether they sleep during the daytime at all, is regulated by their genes, a new study reports.
