Did you know that napping is very common among animals? Humans are one of the few creatures on earth that sleep once per day. Most animals are poly-phasic sleepers, meaning that they alternate sleep and wake cycles throughout a 24-hour period. Many studies say that that napping has many positive effects on our bodies. Naps improve our working memory, prevent burnout, reverse information overload, heighten our senses and creativity, and improve our overall health. One NASA study says that naps increase alertness by 100%. Other studies say that naps are more effective than an average cup of coffee. The mom in this video needs as many naps as possible to keep up with her adorable daughter.
