Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
If you often feel sleepy after having lunch, you’re not alone. In fact, it is a natural part of your circadian rhythm, which controls when you sleep and wake up. Luckily, there are many things you can do to ease the effects of after-lunch sleepiness and get through the afternoon without losing your productivity.
The first thing you should do is to exercise. Physical activity improves blood flow, which provides oxygen and nutrients to your muscles in order to naturally increase energy. It is recommended that you start exercising right after having your meal, before the sleepiness starts. Also, don’t worry too much about the type of exercise: anything that gets you moving like stretching, taking the stairs, or simply walking around for a bit is enough.
Another thing to keep in mind is the important role of water. Many studies have found that a lack of water can cause exhaustion, low mood, and difficulties in concentration. Therefore, start your day with a big glass of water and keep on drinking throughout the day, especially after lunch, to bolster your energy levels.
Your lunch size also matters. A large meal takes more effort to digest, so it is more likely to make you feel tired. Instead of eating large lunches, eat smaller meals throughout the day. Balance a small lunch with mid-morning and mid-afternoon snacks so that you get all of your recommended calories throughout the day. If you plan to try eating small meals throughout the day, make sure that you don’t go more than three hours without eating.
