A brief period of sleep of around 15 to 20 minutes, preceded by consuming a caffeinated drink or another stimulant, may combat daytime drowsiness more effectively than napping or drinking coffee alone.    A stimulant nap (or coffee nap, caffeine nap, occasionally napuccino)  was discovered by British researchers, Horne and Reyner, to be more effective than regular naps in improving post-nap alertness and cognitive functioning.   In a driving simulator and a series of studies, Horne and Reyner investigated the effects of cold air, radio, a break with no nap, a nap, caffeine pill vs. placebo and a short nap preceded by caffeine on mildly sleep-deprived subjects. A nap with caffeine was by far the most effective in reducing driving accidents and subjective sleepiness as it helps the body get rid of the sleep-inducing chemical compound adenosine .  Caffeine in coffee takes up to half an hour to have an alerting effect, hence "a short (<15min) nap will not be compromised if it is taken immediately after the coffee."    One account suggested that it was like a "double shot of energy" from the stimulating boost from caffeine plus better alertness from napping.  This procedure has been studied on sleep-deprived humans given the task of driving a motor vehicle afterwards,  although it has not been studied on elderly populations. 
I love some of these ideas, especially the pirate cake pop medallions – they look unbelievably effective and scrumptious! I have two sons and can affirm that pirate themed parties are always a hit with the boys for their birthdays! We’ve actually had five pirate themed parties between the two of them, this is because one adores Peter Pan, while the older one is obsessed with the Pirates of the Caribbean movies. Either way – I now consider myself as a pirate party planner pro! Though I might have to steal the medallion pop cake idea for another party!
You need immediate alertness. Try a “ caffeine nap. ” Researchers at Loughborough University tested several ways to improve the alertness of drivers and found the “caffeine nap” to be the most effective method. You down a cup of coffee or other caffeinated beverage and then immediately hunker down for a 15-20 minute nap. Again, don’t go any longer than that or you’ll awaken with sleep inertia. The caffeine clears your body of adenosine, a chemical which makes you sleepy. It takes awhile for the caffeine to circulate through your system, so it doesn’t effect the quality of the nap. Instead, it kicks in in tandem with the refreshment you would feel upon awakening from a normal power nap. I’ve personally found the caffeine nap to be effective, especially when you’re crunched for time; it’s easier to get up and keeps you from the temptation of turning a 20 minute nap into an hour and a half session.
