Recent research has shed light on how different levels of illuminance—the measure of the amount of light—can enhance alertness and cognitive performance in humans. The study found that higher light levels affect specific areas of the brain region known as the hypothalamus, enhancing certain cognitive functions during tasks that involve executive and emotional processing. The findings were published in the journal   eLife . The primary motivation behind the study was to understand how varying intensities of light impact the human brain, particularly the hypothalamus, which plays a crucial role in regulating sleep, wakefulness, and cognitive functions. Light exposure is known to affect these areas in animal brains, but the specifics of these effects in humans remained unclear. Animal models have shown that certain brain regions respond to light in ways that affect behavior, but humans have different physiological and neurological complexities. For example, the human cortex matures la...

A meta-analytic review of randomized-controlled trials evaluating the effects of mindfulness-based interventions on cognition found that these interventions consistently yield small-to-moderate improvements in global cognition and various cognitive subdomains. The improvement levels are practically meaningful. The study was published in   Health Psychology Review . Mindfulness is the practice of paying deliberate and non-judgmental attention to the present moment, cultivating awareness of one’s thoughts, feelings, and surroundings to promote mental clarity, emotional balance, and overall well-being. It is often used in psychotherapy as a therapeutic technique to help individuals manage stress, reduce symptoms of anxiety and depression, enhance self-awareness, and develop healthier coping mechanisms by incorporating mindfulness practices and principles into their treatment. Mindfulness-based interventions typically involve practices like meditation, deep breathing, and body scans to...
