Bright Light Exposure Improves Your Workouts Sign. (~8%)

Would be interesting to compare sunlight and artificial light in future studies. You will remember the circadian rhythm series in which I have previously discussed the relevance of light exposure as a means to set, reset and entrain your internal clock in order to reap all sorts of health and performance benefits. Bright (>4000 lux), preferable blue (at least having a blue component) light has repeatedly been shown to increase athletic performance. Studies like Kantermann et al. (2012) show, however, that the efficacy of bright light exposure significantly depends on the chronotype of an athlete.

Let There Be Light: 10 New Studies to Enlighten You About the Health Effects of Light Exposure on Health & Physique

No, the sun does not kill you. If you control your exposure it may extend your life and improve your life-quality significantly. It's about time to "let there be light" to illuminate the benefits of regular well-timed exposure to sunlight and it's short frequency component. Only recently, researchers from the Japanese National Institute of Advanced Industrial Science and Technology (AIST) were able to show that daytime light exposure has significant beneficial effects on cognitive brain activity. Significant enough to have the subjects perform better on an oddball task and to significantly increase cortical activity related to cognitive processes (Okamoto. 2014). But is that really all, bright light, or more specifically, the regular and well-timed exposure to bright light can do for you? The effects on circadian rhythm could be behind the Sun's anti-cancer effects Sunlight, Bluelight, Backlight and Your Clock Sunlight a La Carte: "Hack...

This could be your new wake-up routine: Strong coffee and a bath in blue light. "The abuse of ADHD drugs in people from all social classes is on the rise..." I guess you will have heard or read news like these several times over the past 12 months and in an article over at Forbes.com that was published on St. Nicholas' Day, Todd Essing even claimed: "Adderall use at work by the healthy to enhance cognitive performance is back in the news." Essing cites, among others, Stephen Petrow whose article over at The Atlantic is what Essing calls "a love letter to his 2-3 times per week Adderall use" - and a scary one for Petrow who is a psychologist by trade and says of himself that he "treats lots of hard-driving career-focussed 20- and 30-somethings". (Essing. 2013) I guess Essing, whose previous article "When ‘Study Drugs’ Kill" took a reasonably critical stance towards the use of Adderal and similar drugs by healthy individual...

Hack Your Biological Clock: Light-Induced Circadian Phase Shifts Work So Well That You Better Watch Out to Avoid Accidental Phase Shifting When You Check Your Mails

If you do it on purpose, "hacking" your biological clock can be highly beneficial. If you're doing it out of pure ignorance, though, you're in trouble. In view of the impeding return to standard time, it's probably a good thing, in view of the iPhones, iPads and Facebooks of this world it could turn out to be a serious health problem, though: the ease with which you can "hack" your biological clock - on purpose, but also incidentally. How easy it really is to turn the biological clock of life forward and backward has in fact only recently  been confirmed by Seong Jae  Kim and colleagues from the Northwestern University Feinberg School of Medicine and the Technology Evaluation Center of BlueCross BlueShield Association (Kim. 2013) Fast forward / backward, please! All the scientists had to do to make sure that the 29 healthy young (25.1 ± 4.1 years, M:F=8:21) and 16 healthy older subjects (66.5 ± 6.0 years, M:F=5:11) who participated in the sa...
