Consuming caffeinated coffee can temporarily alleviate less sleep

A new study examining the effects of sleep deprivation again during a work week is likely to find that eating caffeinated coffee during the day helps reduce anxiety and mental function, the compared to decaffeinated coffee.

Although this effect occurred in the first three or four days of restricted sleep, before the fifth and last day, no difference was observed between caffeinated and decaffeinated coffee drinkers. This therefore suggests that the beneficial effects of coffee on people with temporary limited sleep.

It is estimated that over 30% of Western adult adults sleep less than seven to eight hours on weekday nights and 15% regularly sleep less than six hours. This can have a major impact on people’s health and wellbeing, including causing sleep deprivation and impeding alertness and attention.

Previous research suggests that intense consumption of caffeinated coffee may reduce the effects of sleep deprivation on attention deficits and mental function in the short term. This study is among the first to examine whether this effect can be translated into a real world situation, where caffeinated beverages are usually consumed daily by recipients. experience of sleep inhibition. Our study shows that moderate coffee intake can lead to some decisions to reduce sleep over a few days, however, this does not replace a good night’s sleep in the long run. “

The study was conducted at the state-of-the-art Institute of Aerospace Medicine, in Cologne, Germany. 26 participants with a specific genotype of the gene encoding the adenosine A2A receptor were randomly assigned to groups either drinking caffeinated coffee (containing 300 mg of caffeine) or decaffeinated coffee under double-blind conditions. During five days, all participants’ sleep was limited to five hours per night and each day they assessed their subject sleep and were tested on alert levels, alertness, response time, precision and memory.
