Lately, I ran into a little problem where I had the ultimate urge to sleep whenever I eat a meal. Whether it was breakfast, lunch, or dinner, I’d feel like sleeping afterward. Even though I sleep plenty every night, I couldn’t seem to fight this urge to sleep. Luckily I found a sure-win method. I don’t know how good it is for my health though. I figure that if I get sleepy after I eat, it’s because my blood goes to my stomach to aid digestion, hence a blood shortage in the brain and thus giving me the urge to sleep. By holding my head in a position tilted such that the elevation of my head is below the elevation of my heart, I can get the blood flowing to my brain. I hold this position for about 15 to 20 seconds and I sit up straight again, feeling refreshed and awake. Works every time for me.
