Brains are larger than they were in the 1930s. Credit: IdeogramLarger brain size indicates enhanced brain health and cognitive abilities. Since the 1930s, there has been a consistent increase in brain size. A recent study highlights the implications of this growth on the likelihood of developing dementia, specifically Alzheimer's disease.By 2020, more than 55...
In today's fast-paced world, our relationship with food has become complex. We often confuse psychological cravings with true physiological hunger, leading to overeating and unhealthy eating habits. However, there's a powerful practice that can help us reconnect with our body's natural signals and learn what true hunger really means: fasting.Differentiating Psychological Appetite and Physiological...
