10% of the Brain Myth Let me state this very clearly: There is no scientific evidence to suggest that we use only 10% of our brains. Let's look at the possible origins of this "10% brain use" statement and the evidence that we use all of our brain. Where Did the 10% Myth Begin? The 10% statement may have been started with a misquote of Albert Einstein or the misinterpretation of the work of Pierre Flourens in the 1800s. Perhaps it was the work of Karl Lashley in the 1920s and 1930s that started it. The Evidence (or lack of it) Perhaps when people use the 10% brain statement, they mean that only one out of every ten nerve cells is essential or used at any one time? Furthermore, from an evolutionary point of view, it is unlikely that larger brains would have developed if there was not an advantage. Finally, the saying "Use it or Lose It" seems to apply to the nervous system. So next time you hear someone say that they only use 10% of their brain, you can set them straight. "We use 100% of our brains."
Stress (psychological) In psychology, stress is a feeling of strain and pressure. Small amounts of stress may be desired, beneficial, and even healthy. Positive stress helps improve athletic performance. Stress can be external and related to the environment,[1] but may also be created by internal perceptions that cause an individual to have anxiety or other negative emotions surrounding a situation, such as pressure, discomfort, etc., which they then deem stressful. Humans experience stress, or perceive things as threatening, when they do not believe that their resources for coping with obstacles (stimuli, people, situations, etc.) are enough for what the circumstances demand. A very much overlooked side of stress is its positive adaptations.[2] Positive psychological stress can lead to motivation and challenge instead of anxiety. Selye proposed that there are four variations of stress.[4] On one axis, there is good stress (eustress) and bad stress (distress).
Hacking Knowledge: 77 Ways to Learn Faster, Deeper, and Better | If someone granted you one wish, what do you imagine you would want out of life that you haven’t gotten yet? For many people, it would be self-improvement and knowledge. Newcounter knowledge is the backbone of society’s progress. Great thinkers such as Leonardo da Vinci, Thomas Edison, Benjamin Franklin, Albert Einstein, and others’ quests for knowledge have led society to many of the marvels we enjoy today. Your quest for knowledge doesn’t have to be as Earth-changing as Einstein’s, but it can be an important part of your life, leading to a new job, better pay, a new hobby, or simply knowledge for knowledge’s sake — whatever is important to you as an end goal. Life-changing knowledge does typically require advanced learning techniques. Health Shake a leg. Balance Sleep on it. Perspective and Focus Change your focus, part 2. Recall Techniques Listen to music. Visual Aids Every picture tells a story. Verbal and Auditory Techniques Stimulate ideas. Kinesthetic Techniques Write, don’t type.

Not only has he cracked the secrets of productivity, he's figured out how to learn things super quickly! Mental Floss' own Chetan Nandakumar managed to snag a few minutes with him. We're interested in this notion of rapid learning. Things like Argentine tango, for example . Yabu-what? Yabusame is Japanese horseback archery. I've also read that you became a National Chinese Kickboxing Champion in almost no time. Sure. Are there some overarching principles that apply across domains? The first is that material is more important than method . Point two is association, basically the power of associative memorization. The third important thing is self-observation, which is critically important. Your rapid learning approach seems to require a lot of analysis and self-observation. Are there any limits to what someone can learn? Well, there are a few. Any thoughts on education in schools?
Aerobic exercise Cardio. Aerobic exercise (also known as cardio) is physical exercise of relatively low intensity that depends primarily on the aerobic energy-generating process.[1] Aerobic literally means "living in air",[2] and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism.[3] Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time.[1] The intensity should be between 60 and 85% of maximum heart rate. When practiced in this way, examples of cardiovascular/aerobic exercise are medium to long distance running/jogging, swimming, cycling, and walking, according to the first extensive research on aerobic exercise, conducted in the 1960s on over 5,000 U.S. Air Force personnel by Dr. Aerobic versus anaerobic exercise[edit] Fox and Haskell formula showing the split between aerobic (light orange) and anaerobic (dark orange) exercise and heart rate.

If You Are Fit, You Can Take It Easy Pamplemousse/Getty Images New Year’s resolutions tend to war with wintertime malaise. Resolution urges you to work out. Malaise suggests that you linger in bed. But there’s good news for those of us torn between these impulses. The most sobering of the recent studies, published last month in The British Journal of Sports Medicine, looked at a large group of retired elite male athletes, most now in their 50s. Similarly, although in a more compressed time frame, a study published earlier this year found that when a group of world-class kayakers completely quit training (at the end of a competitive season), they rapidly lost strength and endurance. In other words, being almost completely inactive, whether for a short or prolonged period of time, inexorably de-tones muscles and compromises health. But there is a loophole. The researchers then randomly assigned the volunteers to different groups for the next eight months. There are caveats to these encouraging findings, of course.
Really? Treating Sleep Apnea Reduces Inflammation Really? Anahad O’Connor tackles health myths. Doctors have plenty of good reasons to persuade people with sleep apnea to get it treated. The widespread disorder causes disruptions in breathing at night, which can ruin sleep and raise the likelihood of problems like obesity and fatigue. The standard treatment for the condition, a mask worn at night that delivers continuous positive airway pressure, or CPAP, significantly improves apnea, even though many people don’t like to wear it. Many studies have looked at the link between sleep apnea and high levels of inflammatory markers. The data suggested that treating apnea with CPAP significantly reduces levels of two proteins associated with inflammation: tumor necrosis factor and C-reactive protein, or CRP. Treating sleep apnea with positive airway pressure helps to lower systemic inflammation, which might prevent some of the other problems associated with the disorder.
To Treat Sleep Apnea, Some Shed a Mask About 28 million Americans have sleep apnea, which causes repeated awakenings and pauses in breathing during the night, sometimes resulting in loud snoring and gasps for air. For decades, the standard treatment has been “continuous positive airway pressure.” A mask worn at night pushes air into the nasal passages, enabling easier breathing. Joseph A. But the mask is like something from a bad science fiction movie: big, bulky and obtrusive. “For a lot of people out there, the C.P.A.P. machine turns into a doorstop,” said Dr. Now an alternative form of C.P.A.P. is gaining popularity: a patch that fits over the nostrils. Approved by the Food and Drug Administration in 2008, Provent has spread mostly by word of mouth. Bob Bleck, who owns a computer networking firm in Ohio, struggled with poor sleep and chronic fatigue for decades. The diagnosis was severe sleep apnea. His doctor prescribed a C.P.A.P. machine, and Mr. “I had this constricted feeling,” he said. Mr. Dr. For now, Dr. Dr.
Fitness : Zügiges Gehen schützt Gesundheit so gut wie Joggen - Nachrichten Gesundheit Artikel per E-Mail empfehlen Zügiges Gehen schützt Gesundheit so gut wie Joggen "Viele Menschen suchen nach Ausreden, warum sie keinen Ausgleichssport betreiben", sagt Forscher Paul T. Williams. Sein wissenschaftliches Gegenmittel: Es muss nicht das schweißtreibende Joggen sein. "Viele Menschen suchen nach Ausreden, warum sie keinen Ausgleichssport betreiben", sagt Forscher Paul T. Wer gegen Übergewicht, Herz-Kreislauf-Leiden und Diabetes angehen will, muss nicht unbedingt joggen: Zügiges Gehen tut es auch. Das Ergebnis: Rasches Gehen senkt das Risiko ähnlich wie Joggen. "Viele Menschen suchen nach Ausreden, warum sie keinen Ausgleichssport betreiben", sagt Paul T. In nackten Zahlen ausgedrückt taten die Spaziergänger ihrem Körper sogar mehr Gutes als die Jogger: Ihr Risiko, dass erstmals ein Bluthochdruck auftrat, sank um 7,2 Prozent – bei den Läufern "nur" um 4,2 Prozent. Ob Laufen oder Gehen: Wichtig ist, sich überhaupt zu bewegen.
