Wake up with caffeine even when you sleep!

According to RCO News AgencyCaffeine is not just in coffee, but it is found in tea, chocolates, energy drinks and many popular non -alcoholic beverages that make it one of the most consumed psychoanalytic materials around the world.

A new study of the University of Montreal shows how caffeine can do something beyond keeping you awake. In this study, scientists discovered that caffeine can change the way brain recovery at night and affect physical regeneration and cognitive function.

Philipp Thölke, a research trainee at Coco Lab at the University of Montreal, along with Karim Jerbi, professor of psychology and researcher at the Institute of Artificial Intelligence in Quebec, Canada.

In collaboration with Julie Carrier, they used “artificial intelligence” and “electromagnetic” (EEG) to examine the effects of caffeine on sleep, in collaboration with Julie Carrier at the Advanced Sleep Research Center in Montreal, and for the first time showed that caffeine enhances the complexity of brain signals. This work was more evident in younger adults.

“The critical state describes a state of the brain that is in balance between order and chaos,” Jarbi said. It is like an orchestra group musician, either very quiet, nothing happens or is very disturbed and there is inconsistency. The critical state of the brain is the middle that is both organized and flexible. In this case, the brain operates optimally and can process information efficiently, adapt quickly, learn, and decide agility.

“Caffeine stimulates the brain and leads it to a critical state, where the brain is more awake, alert and more reactive,” says Carrer. While this is useful for concentration throughout the day, it can interfere with rest at night, as the brain neither relaxes nor recover properly.

To investigate how caffeine affects the brain on sleep, the team recorded a healthy adult brain activity using “electromagnetic”. They compared the brain activity of each participant on two separate nights.

“We used advanced statistical analysis and” artificial intelligence “to identify delicate changes in neural activity,” said Tulke, a senior author of the study. The results showed that caffeine increases the complexity of brain signals, which indicates a more dynamic and less predictable neurotomy. This occurs in the “Sleeping Sleep” phase (NREM), which is critical for stabilizing memory and cognitive recovery.

Scientists also discovered significant changes in the brain’s electrical rhythms during sleep. Caffeine weakened more slow fluctuations, such as theta and alpha waves, which are usually associated with deep and restorative sleep, and stimulate the beta wave activity, which is more common in awakening and mental conflict.

“These changes show that even during sleep, the brain is affected by caffeine in more active and less restorative state,” Jarbi noted. This change in brain rhythmic activity may help explain why caffeine affects the efficiency of the brain during the night with potential consequences for memory processing.

The study also showed that the effects of caffeine on brain dynamics in young adults between 20 and 27 years were significantly greater than those of middle -aged 41 to 58 years. The young adults responded more to caffeine. This reaction may be due to the higher density of adenosine receptors in their brains. Adenosine is a molecule that gradually accumulates in the brain throughout the day and makes it feel tired.

“Adenosine receivers naturally decrease with age and reduce the ability of caffeine to block them and improve brain complexity, which may partially explain the effect of caffeine observed in middle -aged participants,” Carrer said.

These age -related differences show that younger brains may be more susceptible to caffeine stimulants. Given the widespread use of caffeine around the world, especially as a daily treatment for fatigue, scientists emphasize the importance of understanding its complex effects on brain activity in age groups and different health conditions.

Researchers say more research is needed to clarify how these neurological changes affect cognitive health, daily function, and possible guidance of personalized advice for caffeine consumption.
