If the goal is not to fall asleep at the wheel, then long-range tips will do. First, chew something. everything will do: seeds, candies, toffee, gum, fruits. If the mouth is busy, the brain does not shut down as quickly. Secondly, sing along to the radio and talk. Experienced auto-travelers say - if the conversation has calmed down in the car, then expect trouble. This also includes the oral solution of complex mathematical problems. Thirdly, the already repeatedly mentioned energy sources are both purchased and homemade. Often the danger of their use exceeds the need to have time to get somewhere. Therefore, I strongly do not recommend it.
In addition to Elizabeth's answer, I would like to add that any adaptogen is suitable for toning, for example, the same Eleutherococcus, Leuzea, ginseng, lemongrass. The latter is best to cope with the task at hand, because has the strongest effect on the nervous system among all adaptogens. And if we talk specifically about Eleutherococcus, then it is not suitable for everyone; so, for example, for people with the 4th blood group, it is useless.
Well, of course, we must not forget about caffeine in any of its forms, such as tea (both black and green), cocoa, coffee ( classic).
It should be added that caffeine should be used together with glucose (coffee with sugar, for example), because only in combination with glucose it gives the best result.
Finally, I will say, that for me personally, a good way to invigorate is to take a cold shower, which in addition stimulates the production of happiness hormones - endorphins.
Better sleep, I'm almost exhausted once. Bolt went to study during pre-graduation design, and then in a week from 10% to 100% readiness the diploma brought, well, of course, sleep for a maximum of an hour, a couple of liters of coffee and a pack of 3 cigarettes (he smoked tady, he was stupid, and the motto the then sounded - sex drugs and rock'n roll; at right now, Putin, Kirkorov and healthy lifestyle), in short, lay in a warm bathroom since the morning, having not slept normally for four days and such an ass came to visit that the defense of the diploma seemed like garbage, my heart began to pound madly , I could not breathe, but for so long that I almost died three times and turned blue at the same time turning pale. After that, understanding the cause of my comotosis, I chilled out for many hours, well, somewhere around 5, and it seemed like everything became normal. The second graduation project was already doing at a more measured pace, living something hot.
P.S. And so as not to sleep too much coffee in a Coke, but the most disgusting is to make an alcoholic tincture on coffee (I drank it like that), at first it seems like everything is fine, but then considering that you just sit asleep and you slowly sober up like a ram.
I wrote my diploma in 2 days. 48 hours, of which I slept only 3. The secret is simple - a cold cocktail of cola and coffee. Pour 2 teaspoons of instant coffee into a large mug, pour boiling water up to half, pour the remaining half with cola, add ice and a slice of lemon. The drink is not recommended for people with a weak heart. motor flutters notably. The bottom line is that cola irritates the walls of the stomach because of this, more caffeine gets into the blood (so I was told, I myself xs). Pins in a way that no Red Bull did. It is not worth it to abuse it, the recommended frequency of consumption: no more than 2 times a month. Use in exceptional cases and freebies for your exams.
If you need a day where you can't sleep, try preparing yourself the night before with a full night of rest. You will be stealing your time one way or another from the first or second day so it is important to prepare yourself for the future. Engage in exercises to awaken yourself and so that the blood moves faster.
Next, prepare a healthy breakfast and eat well throughout the day to balance energy and blood sugar.
During the important time, where you must not sleep but want to, chew menthol. Smell lemon or other essential citrus oils. Drink a lot of water so that the water goes to the brain and it works soberly.
If you have any questions, ask))
A person vitally needs high-quality sleep for normal functioning, especially for thought processes and psyche. Therefore, if possible, it is still better not to deprive yourself of sleep (even during the session). If it is vital not to sleep, exercise, chewing gum and herbal preparations based on Eleutherococcus help to fight sleep. True, when using the latter, there is a risk of not falling asleep later, even if there is such an opportunity. Please, take care of your health and safety of yourself and those around you, do not drive in a state of acute lack of sleep. Remember that your life and health are more important than anything, even exams.
