High-dose caffeine improves reaction time but increases nervousness
A Spanish study found that 6 mg/kg of caffeine improved reaction time but caused nervousness and increased energy, while 3 mg/kg had no effect.
Caffeine can disrupt your sleep — even when consumed 12 hours before bed
A new study has found that a 400 mg caffeine dose disrupts sleep up to 12 hours before bedtime, yet many people fail to notice these disruptions, especially when consumed earlier in the day.
Caffeine’s impact on brain’s mesolimbic dopaminergic pathway could reduce alcohol’s addictive effects
Researchers found that caffeine blocks alcohol’s ability to increase dopamine in brain reward areas, potentially reducing alcohol's rewarding effects. This suggests caffeine could play a role in preventing or treating alcohol addiction.
Moderate coffee consumption during pregnancy unlikely to cause ADHD in children
Research found no causal link between moderate coffee intake during pregnancy and children’s neurodevelopmental issues, supporting guidelines that low to moderate caffeine consumption (under 200mg daily) is safe for expectant mothers and their babies.
Polyphenols from coffee ameliorate cognitive deficits caused by stress
Adding coffee polyphenols to the diets of male mice exposed to early-life stress improved cognitive function and increased microglia survival, suggesting a potential nutritional intervention for mitigating stress-induced cognitive deficits.
Caffeine exacerbates brain changes caused by sleep loss, study suggests
Caffeine may worsen brain grey matter loss during sleep deprivation, potentially hindering recovery and exacerbating the negative effects of chronic sleep restriction, new research reveals.
Genetic differences found to influence coffee drinking behaviors
A new study has found that coffee consumption is heritable, with specific genes influencing how much coffee people drink and its association with other substance use behaviors.
Creatine nitrate and caffeine combo boost cognitive performance, study finds
A recent study found that a combination of creatine nitrate and caffeine significantly improves cognitive function in resistance-trained males.
Coffee might have protective effects against Parkinson’s disease, according to new research
Coffee drinkers have a significantly lower risk of developing Parkinson’s disease, with the highest consumers nearly 40% less likely to develop the condition compared to non-drinkers.
Caffeine use prevents stress-induced impairment of spatial memory
A study has found that adding caffeine to the drinking water of rats exposed to social isolation stress can protect them from developing memory impairments.
New study sheds light on the double-edged sword of caffeine and its impact on sleep-deprived individuals
Researchers discovered that while a single dose of caffeine can improve attention in sleep-deprived individuals, regular high consumption of caffeine leads to diminished attentional performance, as well as alterations in brain activity.
New research raises questions about caffeine’s impact on brain plasticity
Chronic caffeine use may reduce brain plasticity, key to learning and memory, according to a study. This contrasts with expectations of caffeine enhancing cognitive abilities.
Moderate coffee and tea intake linked to lower risk of cognitive decline
Drinking moderate amounts of coffee or tea can decrease the risk of cognitive disorders such as dementia, according to a recent study published in Nutrition Reviews.
Caffeine intake may benefit Asians with high-risk Parkinson’s gene variants, study suggests
Regular consumption of tea and coffee containing caffeine could lower the risk of Parkinson's disease in Asians with specific LRRK2 gene variants. This finding, from a study involving 4,488 participants, points to potential preventative strategies for at-risk populations.
Caffeine can compromise working memory function and lead to changes in brain activity patterns
Recent research in Scientific Reports suggests that daily caffeine intake might impair rather than improve working memory. While previous studies highlighted caffeine's acute benefits for attention and alertness, this research focused on the long-term effects of sustained caffeine consumption on...
