How to stay awake after a long night of sleep?

Insomnia or staying up all night to study, work or in case yourself, family or friends encounter an emergency situation... are all very good reasons that make each person at least one the time in your life that you've had a sleepless night.
A sleepless night greatly affects a person's brain, reaction ability, concentration or memory. In fact, scientists have shown that facing daily activities after a full night of sleep, you will be like a drunk guy.
Sleep experts say that the body will be at its weakest when it has to stay awake for too long. Due to the natural flow of circadian rhythms in the body, people will be in a really bad state if they stay awake for 24 hours, it makes them unable to control what is going on and always in a state of lack of alertness. . It is also the worst time for a person to think about driving home.
The monotony of the road they take, combined with the onset of sleepiness, can cause drivers to fall asleep uncontrollably. In a 2005 survey on drowsiness while driving, up to a third of the drivers in the study admitted that they had at least once fallen over the wheel because they were too tired while the car was still driving. running on the road.

However, if it is forced to complete daily tasks after a sleepless night, the brain is still capable of trying to make up for the problem. In a study using functional magnetic resonance imaging (MRI), 16 young adults who were completely awake for about 35 hours completed individual tests with increasing difficulty. The MRI images showed increased activity in certain areas of the brain because the condition was essentially drawing more energy from the brain than needed in people who got enough sleep.
The brain can provide cognitive abilities to a person who don't get enough sleep that under normal conditions they don't need to use. That allows sleep-deprived people to still be able to perform at an average level on assigned tasks.
The circadian clock can also help keep people awake by increasing stimulation to the brain to keep the brain functioning properly. There are two times when a person's biological clock most clearly helps them stay awake, one is around 10 am and the other is 6-7 pm. During these times, sleep-deprived people may feel better, but are still more likely to experience memory loss, slow reactions, and decreased concentration.

Fortunately, we always have ways to limit sleepiness, bring alertness before a very long working day ahead. Some of those methods can be mentioned as:
A nap : A nap is considered an "antidote" for the nervous system after a long night of sleep. In a study conducted at the US National Aeronautics and Space Administration (NASA) led by Rosekind, transpacific flight pilots who took an average of 26 minutes of naps were reduced to more than half the chance of showing signs of drowsiness during flight.

Even a short nap of just 10 minutes can have a positive effect on the body. However, if people sleep longer than 45 minutes, sleep-deprived people are likely to feel more tired when they wake up, which is caused by an effect known as sleep inertia every time a person wakes from a nap. deep, always wanting to pull them back to sleep. But when those feelings are overcome, the body will benefit from naps.
Drink coffee or other drinks containing caffeine: Using coffee or energy drinks containing caffeine helps the nerves become more alert. According to research, most sleep-deprived people need between 100 and 200 milligrams of caffeine depending on their body weight. A small cup of coffee contains about 100 milligrams of caffeine, while caffeine supplements are often available in doses of 100 or 200 milligrams. It takes about 15 to 30 minutes for the body to feel the effects of caffeine, and these effects can last for about 3 to 4 hours. The best way to use coffee used by NASA pilots is to drink a cup of coffee and take a nap for about 30 minutes. They will wake up feeling refreshed and ready for work. However, do not overdo caffeine, the masking of sleepiness is increasing, making you unable to control when the body really needs to rest and that can cause serious harm. for health.
Keep your body active : Walking or working out will improve blood circulation while exercise can improve brain focus. When moving, the muscles give feedback to the nervous system through the nervous system to help maintain alertness.

Even changing activities or engaging in a conversation can improve alertness, but as soon as activity or talking is stopped, drowsiness can immediately follow.
Avoid doing many things at the same time: After a long night of staying up, memory loss will become even more severe. That means the brain cannot remember many things at once. A study of 40 young adults who stayed awake for 42 hours found that the brain's memory capacity decreased by up to 38%. Imaging tests (cranial magnetic resonance imaging) have confirmed that the part of the brain involved in sending and receiving information is often inactive or underactive in people with sleep deprivation. Each person can always try to wake up the body after a sleepless night or stay awake by many different ways such as washing your face with cold water, drinking a cup of coffee or keeping your body active....
However, sleep is as important to everyone as water, oxygen and food. Prolonged lack of sleep can lead to many adverse health consequences. Every time you go back to sleep, your body will go into a deeper sleep than usual. People who are sleep-deprived will have a feeling of sleeping better, even sleeping 10 to 12 hours later. It's the amount of time the body heals itself after a long night of sleep.
