Egypt Independent: Living-Main news en Well-timed exercise might improve learning <img src="" alt="" title="" class="imagecache imagecache-media_thumbnail" width="152" height="114" /><p>Aerobic exercise four hours after a memorization task, but not exercise right afterwards, was linked to improved recall in a series of Dutch experiments.<br /><br />Newly-learned information turns into long-term knowledge through a process of stabilization and integration of memories, the study team writes in Current Biology. This requires certain brain chemicals that are also released during physical exercise, including dopamine, noradrenaline (norepinephrine) and a growth factor called BDNF, they explain.<br /><br />&ldquo;The brain processes new memories for a while after learning. Physical exercise is able to improve these post-learning processes,&rdquo; senior author Guillen Fernandez, director of the Donders Institute for Brain, Cognition, and Behavior in Nijmegen, the Netherlands, told Reuters Health by email.<br /><br />To explore when exercise would most improve learning, researchers recruited 72 participants and tasked them with learning to match a series of 90 locations with pictures over a 40-minute period.<br /><br />The participants were split into three groups: one group exercised immediately after learning, one group exercised four hours later and one group did not exercise at all.<br /><br />The exercise groups did interval training for 35 minutes on a stationary bike, including spurts at maximum intensity.<br /><br />Two days later, the participants returned to the lab to test how much of what they&rsquo;d memorized they could recall. During the recall test, the each subject was in a MRI scanner so researchers could monitor activity in different areas of the brain.<br /><br />The group that had exercised four hours after learning remembered significantly more information on the follow-up test, while the immediate-exercise group did no better than the group that did not exercise.<br /><br />Activity in the hippocampus, a part of the brain associated with forming memories, was very similar among people in the delayed-exercise group during the recall task, but less consistent in the other participants, the researchers note.<br /><br />They speculate that the consistency of activation in the hippocampus in the delayed-exercise group could indicate greater &ldquo;efficiency or coherence&rdquo; in the way the brain pulls up the memory and &ldquo;might relate to differences in memory strength.&rdquo;<br /><br />While strong memories will be remembered no matter what, Fernandez said, weaker memories that would normally be forgotten within a day may last longer if the brain releases more dopamine and norepinephrine.<br /><br />People looking to improve their learning should perform fairly intense exercise to make sure that enough of the critical brain chemicals are released, he said, but cautioned against taking this too far. &ldquo;Very intensive exercise might also have negative effects.&rdquo;<br /><br />The authors note that more research is needed to determine if exercise will help memories last beyond the two-day period they studied.<br /><br />They add that the type of memory may be important, and that procedural or &ldquo;body&rdquo; memory of activities like tying a shoe may be better helped by immediate exercise than other kinds of memories.<br /><br />Having a regular exercise routine may be helpful as well said Marc Roig, an assistant professor at McGill University in Montreal who studies the effect of cardiovascular exercise on memory.<br /><br />Several weeks of cardio exercise, such as jogging, can make the hippocampus larger and improve people&rsquo;s memory, he told Reuters Health.<br /><br />The type of exercise may not be important, though, added Roig, who was not involved in the new study. &ldquo;Most studies have looked into aerobic exercise but recent data shows that resistance training and high intensity interval training may also be beneficial.&rdquo;<br /><br />&ldquo;When thinking about how to maximize your training regimen to improve/maintain memory do not ask yourself only what type of exercise, intensity or frequency is the best. Ask yourself when to train to achieve the best results,&rdquo; Roig said.</p> Sat, 18 Jun 2016 12:11:00 +0000 Reuters 2470465 at sites/default/files/photo/2015/07/31/43/t1larg.jpg Museum exhibit recreates signature dishes from top restaurants around the world <img src="" alt="" title="" class="imagecache imagecache-media_thumbnail" width="152" height="114" /><div>The San Francisco Museum of Modern Art has opened a gastronomic exhibit that replicates dishes from some of the top Michelin-starred restaurants around the globe allowing visitors to embark on a culinary world tour without leaving the city.</div><div>&nbsp;</div><div>The vision of chef Corey Lee, who helms the triple Michelin-starred San Fran restaurant Benu, &ldquo;In Situ&rdquo; brings the cuisine of superstar chefs from France, the UK, Italy, Hong Kong, Denmark, Spain and Japan to diners at the recently opened museum.</div><div>&nbsp;</div><div>For the exhibit-restaurant, Lee worked with chefs to faithfully recreate each dish.

As the sun goes down, your brain gradually increases its production of growth hormone. This is the magic bullet that restores your body, revitalising your skin, building new muscle and repairing any damaged cells. So the more you wind down in the evening, the more growth hormone you have available to repair your body tonight.<br /><br /><strong>Turn off technology</strong><br /><br />Avoid your phone, laptop, tablet or TV. Switch them off and you&#39;ll switch off too. Electronic devices emit a short-wavelength light, even on standby mode, that interferes with melatonin production.<br /><br /><br /><strong>Wear comfy clothing</strong><br /><br />Wear loose and comfortable PJs to sleep in. Tight clothing can curb melatonin production by 60 percent.<br /><br /><strong>Invest in accessories</strong><br /><br />Trust these tried-and-tested accessories to help you produce more melatonin, the sleepy hormone: Blackout blinds or a sleep mask. Make your bedroom as pitch black as possible &ndash; your body only produces melatonin in the dark. If your optic nerve detects light, you will wake up.<br /><br /><strong>Early to bed...</strong><br /><br />Four simple words that will help you consistently get the right amount of sleep: get to bed earlier, by 10 p.m. if you really want to wake up feeling younger. Growth hormone is at its peak, so this is when physical repairs begin. It will stay elevated until 2 a.m. Aim to get into bed just 15 minutes earlier each day until you&#39;re in bed, lights out, at 10 p.m.<br /><br /><strong>Early to rise</strong><br /><br />6am is the earliest good time to wake up. Your psychological repairs are done (well, as done as they&#39;re going to get for today) and your rise-and-shine cortisol rises with the sun.<br /><br /><strong>And finally....Keep a regular sleep pattern</strong></p><div>As well as going to bed early, also try to get to bed at a similar time each day. The same goes for getting up. Keeping a regular sleep schedule helps your body clock switch on and off at the right time, which means you&#39;re less likely to be awake when you don&#39;t want to be.</div><div>&nbsp;</div><p>Should you need another incentive, it&#39;s nice to know that people who go to bed and wake up at about the same time each day have lower body fat than those with more erratic schedules.</p> Sun, 12 Jun 2016 13:33:00 +0000 AFP 2470307 at sites/default/files/photo/2015/07/31/43/sleep-tips.jpg
