Much research has been done on how to overcome sleep deprivation. Because there is no substitute for adequate sleep to keep people functioning normally. But sometimes there is no complete sleep. And in this situation, the researchers have tried to know whether coffee can play an effective role in maintaining the focus of the work.
Recently, Michigan State University psychology professor Kimberly Fenn conducted a study on sleep deprivation. Students from his university's 'Sleep and Learning' lab helped him in this research. They tried to find out what could be done to reverse the negative effects of sleep deprivation on the human body. Whether coffee helps to compensate for lack of sleep or power nap is more effective, these answers are basically what they wanted to find through the research.
Adequate sleep is necessary if we want to complete our daily tasks properly. 6 to 7 hours of sleep is enough to get rid of the tiredness after a long day. But in our busy life-schedule it becomes difficult to find a 7-hour slot for sleep many times. As a result, lack of sleep is seen. Many times our body loses its ability to function properly due to lack of adequate sleep. It also affects our mental health.
Many people therefore opt for power naps instead of long naps. A nap is also called jittery sleep. Because the duration of nap is less than sleep. Again, many find refuge in caffeine. These methods are the most popular among busy citizens to shake off fatigue and find energy to work again.
But research says there is no substitute for sleep.
That's what Fenn's research says
Lack of sleep affects not only people's attention but also their cognitive activity. Cognitive activity refers to performing a complex task using memory, intelligence, common sense, calculation ability. For example, suppose you are making a cake. Here you need to follow few steps. If any step is missed, the cake will not be prepared properly. That is, it is a kind of cognitive process. So Kimberly Fenn and her team conducted an experiment on two groups of people.
Here on the first day participants are given some cognitive tasks. Then a group is told to go home and rest. Another group was asked to stay awake all night in the lab. On the second day, participants who were allowed to sleep in returned in the morning. Each again completed the cognitive tasks.
Those who spent the night with little or no sleep were now asked what they did while awake. It is known that most of the participants spent the night on energy drinks and coffee. But interestingly, even after staying up all night, the performance of those who consumed caffeine was similar to that of the participants who got enough sleep. Caffeine also boosted performance in those who were able to sleep. But it didn't help solve the cognitive tasks correctly.
That is, coffee will provide you with some kind of energy to move, but it will not help you solve complex physical and cognitive processes at all. That is, you may be able to play Candy Crush with coffee but not score well on math tests.
So does a power nap reduce sleep deprivation?
We often take a quick nap of half an hour during the day. It can increase our energy and performance. So it's also logical to think that sleeping at night would have a similar effect. But studies have shown that half an hour or an hour of sleep at night is not really helpful. Participants who slept did no better on simple attention tasks or more complex placekeeping tasks than those who stayed up all night.
That is, in this case, caffeine is more effective than jhtica sleep. However, caffeine probably won't help you with tasks that require complex thinking.
In short, adequate sleep is essential for your mind and brain and there is no substitute for sleep.
