Power naps are frequently recommended as a way to improve cognition, focus and reduce tiredness. But what are the physiological effects on the body, and why can longer nap times leave us more groggy and tired than before?

Discovered in 1929, Vitamin K has a crucial role in preventing bleeding and coagulation, especially in newborns, and is important for our bone and cardiovascular health. Ongoing research also suggests that vitamin K can assist with cognition, skin health and wound healing.

The ketogenic diet (KD) is recognised for its potential to support fat loss, but its impact on physical performance, especially for athletes, remains contentious. While anecdotal evidence suggests performance benefits in some scenarios, scientific studies show mixed results. KDs may promote fat oxidation and weight loss but might not be ideal for enhancing muscle mass or performance in high-intensity activities.

During prenatal development, amino acids are vital for proper growth and formation of the fetus, and contribute to the development of organs, muscles, and the nervous system. They also have a direct impact on other compound molecules such as nitric oxide that supports placental growth and enhances maternal-fetal blood flow, ensuring adequate supply of nutrients and oxygen.

Slow breathing is often defined as taking about six breaths per minute, and many of us are not far away from this figure in normal circumstances. This, of course, will differ when it comes down to our age, weight or how we breathe – through our nose or mouth. Studies have shown that slow breathing, through our nose, can positively impact our memory, cognition, stress levels, blood pressure and even our bowel movements.
