Problem: Article: You'll be working on it when your brain is fresher, which will make it easier than if you tried to do it when your brain is tired. Also, once you get it out of the way, you'll feel like you've done something big. In addition, your other work will seem easier after the hard stuff. Studying for too long without breaks can wear you down. In addition, you'll stop absorbing information as well. Be sure to take regular breaks at least once an hour. Get up and walk around. Get a cup of tea. Do jumping jacks, or go talk to a friend for a few minutes. Just take a mental break, and you'll be more prepared to jump back in. Though you need to take breaks, when it's time to study, you need to study. Don't doodle, or write random notes in the margins. Actually get down to work when you're supposed to, and you'll cut down significantly on your study time. Instead of trying to study one subject for hours, skip from subject to subject, especially if you have several tests ahead. For instance, try moving subjects when you take a break. This type of studying keeps you more interested in what you're learning, helping you to learn what you need to know faster.
Summary: Get the hard subjects out of the way first. Take breaks. Don't procrastinate. Skip around subjects.

Problem: Article: Many people use snuff as a way to transition away from tobacco altogether. You do not inhale snuff, and some studies indicate this makes it less addicting or dangerous than tobacco products. However, the results of such studies are debatable. If you want to use snuff to transition off of tobacco products, you should talk to a doctor first. Many doctors advise against using snuff to quit, as this may just create another bad habit. Instead of snuff, some medical doctors may prescribe nicotine replacement sprays, patches, pills, or gums. Talk to your doctor about your options before settling on snuff as your route to quit. Many people believe nasal snuff does not come with the health risks associated with smoking. However, understand that snuff has similar health risks to tobacco. It increases your risk for heart disease, stroke, cirrhosis, all cancers, including lung cancer, and respiratory and digestive diseases. The risks are arguably slightly lower than smoking cigarettes, but still exist for smokeless tobacco products like snuff. Nasal snuff contains nicotine, which is a physically addictive substance. Recognize the signs of nicotine dependency. If you are displaying these signs, you may want to reevaluate your use of nasal snuff. You can become dependent on nasal snuff, making it difficult to quit. You may try to quit, but find you are unable to. If you stop using snuff for a few days, you may experience withdrawal symptoms like irritability, strong cravings, anxiety, low mood, difficulty concentrating, and increased hunger. You may keep using snuff even if health problems arise and your doctor recommends quitting. Over the longterm, using snuff can cause damage to your nasal cavities. As you're snorting snuff through your nose, your nostrils become irritated and damaged over time. Longterm users of snuff sometimes develop chronic rhinitis. This condition causes a persistent runny nose and blocked nasal passages.
Summary: Be careful when using snuff to quit tobacco. Learn about the health risks. Recognize signs of tobacco dependency. Be aware of longterm nasal problems.

Problem: Article: Walk around a little if you can. Resist the urge to sit or lay down. Also avoid leaning up against anything. If your eyes are heavy, you may doze off. As long as you are standing up and moving you should be able to avoid falling asleep. Cold water works best. The colder the better. Something to sort of shock you into waking up. You can easily excuse yourself to the bathroom to do this. The goal here is to make yourself uncomfortable. If your face is cold you will be less likely to fall asleep. If you have short, combed-over hair you could put cold water on your scalp too. This is a lot easier in winter or in cold offices. Take off that jacket or scarf. Roll up your long sleeves. Grab a glass of ice cold water. Take a few gulps, refill, and keep it at your desk. If you have a space heater at your desk, turn it off. You may even want to turn a fan on to keep you cooler. You may opt to start doing things more quickly. Stand and march in place while at your desk. If you can take a quick break, do jumping jacks or run in place. This will get your heart rate up. More blood will be moving to your brain and your lungs will start working harder to provide oxygen to the blood. As your heart rate rises you will be more awake and alert. Taking a shower will also influence your cardiovascular system by raising your blood pressure. If you are tired, a monotonous task will prompt your eyes to become very heavy. If you can switch tasks and do something different, try that instead. If it involves paying close attention to something or someone else that's even better. When our minds are engaged we become more awake and alert. If you can listen to something on the radio or on your phone do so. If you have a favorite radio station or upbeat playlist or music album listen to that and sing. Try listening to a book on tape. If you like keeping up with current events, news radio may also keep your mind engaged. If you are unable to shake your midday sleepiness you may not be getting enough rest in general. Consider establishing a regular sleep routine and avoiding snacks and beverages that can make you sleepy. Consult a physician if you have a regular sleep schedule and still feel tired during midday.
Summary:
Stay standing as much as possible. Splash water on your face. Lower your body temperature. Raise your heart rate. Engage your mind in an entertaining task. Eliminate the source of your tiredness.
