Sleep and fatigue are ever-present companions for a long distance motorcyclist. And there are as many possible solutions bandied about as are anecdotes of close calls due to the two. I had also done a detailed article on this in the MAX section of our xBhp Magazine a few months ago. The commonest sleep-fighter apparently is caffeine which is also the easiest to get in through that common road-side cuppa. This article here sourced from the link here shows an interesting relationship between the intake of caffeine followed by a short nap while it takes effect in the body to get full benefits of the resulting increased alertness levels.
Scientists agree: Coffee naps are better than coffee or naps alone
If you're feeling sleepy and want to wake yourself up — and have 20 minutes or so to spare before you need to be fully alert — there's something you should try. It's more effective than drinking a cup of coffee or taking a quick nap.
It's drinking a cup of coffee and then taking a quick nap. This is called a coffee nap.
It might sound crazy: conventional wisdom is that caffeine interferes with sleep. But if you caffeinate immediately before napping and sleep for 20 minutes or less, you can exploit a quirk in the way both sleep and caffeine affect your brain to maximize alertness. Here's the science behind the idea.
How a coffee nap works
To understand a coffee nap, you have to understand how caffeine affects you. After it's absorbed through your small intestine and passes into your bloodstream, it crosses into your brain. There, it fits into receptors that are normally filled by a similarly-shaped molecule, called adenosine.
Adenosine is a byproduct of brain activity, and when it accumulates at high enough levels, it plugs into these receptors and makes you feel tired. But with the caffeine blocking the receptors, it's unable to do so. As Stephen R. Braun writes in Buzz: the Science and Lore of Alcohol and Caffeine, it's like "putting a block of wood under one of the brain’s primary brake pedals."
#1 IT TAKES ABOUT 20 MINUTES FOR CAFFEINE TO HIT YOUR BRAIN
Now, caffeine doesn't block every single adenosine receptor — it competes with adenosine for these spots, filling some, but not others.
But here's the trick of the coffee nap: sleeping naturally clears adenosine from the brain. If you nap for longer than 15 or 20 minutes, your brain is more likely to enter deeper stages of sleep that take some time to recover from. But shorter naps generally don't lead to this so-called "sleep inertia" — and it takes around 20 minutes for the caffeine to get through your gastrointestinal tract and bloodstream anyway.
So if you nap for those 20 minutes, you'll reduce your levels of adenosine just in time for the caffeine to kick in. The caffeine will have less adenosine to compete with, and will thereby be even more effective in making you alert.
