Napping May Help Undo Negative Health Effects Of A Sleepless Night.

“a small study of 11 healthy men published online in the Journal of Clinical Endocrinology & Metabolism” suggests that “the negative health effects of a sleepless night can actually be reversed by a good nap.” For the study, participants underwent two laboratory sleep sessions. In the first session, “the men only got two hours of sleep and then had their urine and saliva measured and analyzed for hormonal changes.” The study found that when men only slept for two hours, they had a 2.5 increase in norepinephrine, a hormone and neurotransmitter which responds to stress. That increase can up the body’s heart rate and blood pressure. The men also had low levels of the protein interleukin-6 which is critical for having a proper immune response. However, when the men were sleep-deprived but napped the following day, the researchers found there were no changes in either their protein or hormone levels.For “the second session, the men once again only got two hours of sleep, but this time they also took two 30-minute naps the following day.” Again, they provide samples of urine and saliva. http://time.com/3703317/napping-good-for-you/
