However, it was found that though there was a significant difference in the first three to four days of restricted sleep, no difference was seen in the fifth to sixth days between the effects of caffeinated and decaffeinated coffee. This shows that the effects of coffee on cognitive function are temporary.
Research shows that 15% of adult populations from the West get less than six hours of sleep on a weekday night and that more than 30% get less than the recommended seven to eight hours of sleep. This can lead to detrimental effects on people's health and wellbeing, like increased sleepiness and impairing our attention and vigilance.
For the study, 26 participants with a distinct genotype of the adenosine A2A receptor encoding gene were assigned randomly to groups either drinking caffeinated coffee with 300 mg of caffeine or decaffeinated coffee under double-blind conditions. All participant’s sleep was restricted to five hours per night, for five days, and each day they were asked to rate their subjective sleepiness and were also tested on levels of alertness, memory, reaction time, vigilance, and accuracy
The co-author of the study, Denise Lange, commented that prior research suggests that acute consumption of caffeinated coffee can decrease the impact of sleep deprivation on deficits of attention and cognitive function in a short-term setting.
She adds “This study is among the first to examine whether this effect can be translated into a real-world situation, where caffeinated drinks are commonly consumed every day by people who experience chronic sleep restriction. Our study indicates that moderate coffee intake can mitigate some repercussions of reduced sleep over a few days, however, this is not a substitute for a good night's sleep in the long term."

Immune System Can Be Badly Affected By Sleep Loss
Scientists from Netherlands and the United Kingdom have proved that severe sleep loss and physical stress are equally detrimental and can adversely affect our immune system.
