Again, a word-pair association task revealed wearing an eye mask helps with learning new information and forming fresh memories. In addition, data provided by the headband suggests there is an association between mask wearing and more slow-wave sleep time, known to be important when it comes to memory boosts.

"The benefit to memory was predicted by time spent in slow-wave sleep while wearing the mask," write the researchers.

"This suggests wearing an eye mask during sleep is an effective, economical, and non-invasive behavior that could benefit cognitive function and lead to measurable impacts on everyday life."
