I've Been Wearing These Every Night for Two Weeks.

A couple of weeks ago I started a little experiment with the light exposure my eyes received before going to bed. I can't remember exactly what the trigger was but I recall an article loosely about the effect of blue light before going to sleep and the impact that had on the quality of sleep and sleep hygiene in general. 

The theory is that the blue light emitted by artificial lighting before bed, such as from the screens of electronic devices including TVs, computers, and phones, stimulates the brain like early-morning light, triggering alertness and altering fundamental circadian rhythms. Over the last few years I have become hypervigilant about pursuing healthy sleep hygiene habits and quality uninterrupted sleep, because bad sleep results in a build-up of molecular waste products in the brain, poor / handicapped cognition, and a general brain phenotype that might best be described as prematurely aged (see: http://www.urmc.rochester.edu/news/story/index.cfm?id=3956).

I decided to invest in two pairs of glasses designed to block blue wavelengths of light:
1. Generic Uvex safety eyewear (pictured) http://www.amazon.com/gp/product/B000USRG90/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and 
2. BluBlocker sunglasses http://www.amazon.com/gp/product/B00DE0MVD2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

The BluBlockers are obviously more stylish but they let in external light from the sides / periphery and so the generic - and much cheaper - glasses, which wrap around the head are better and provide better light blocking properties.

My experience has been very positive. In general I've been donning the glasses about an hour or two before bed and only take them off after the lights have been turned off. I'd say that 99% of the time at this time of day I am consuming information or media through a bright screen of one type or another, most often my home computer. Yes, image quality as regards colour saturation and richness suffers.

But I cannot remember falling asleep so quickly, nor sleeping so solidly - not that I'd classify my sleep beforehand as bad at all, just room for improvement. I feel fresher and more active in the morning and more alert during the day. A proper experiment will demand that I stop using the glasses for two weeks in order to compare the effects. The only drawback I've noticed, aside from the obvious loss of visual richness while wearing the glasses, is that my performance while trying to play first-person-shooters like Titanfall suffers considerably, which is interesting in and of itself. 

Finally, most importantly, and the reason for this post is that by coincidence I came across this article today http://today.uconn.edu/blog/2015/03/lighting-adjustments-necessary-for-better-health-researchers-say/ about the latest experiments and research that suggests adjustments to modern lighting are necessary for better sleep and health by restoring our bodies' natural circadian rhythms - essentially preventing blue light from suppressing our natural production of melatonin. 

Another option I wouldn't mind exploring in future is house-wide Philips Hue lighting automatically set up to not emit blue light after a certain time of night. And emitting extra blue light in the mornings of course. 

This is just my experience and if you suffer from poor sleep and, like me, are immersed in a screen of some sort most nights before bed, you might want to conduct this little experiment yourself. The glasses are only $10 after all.

«You have guns because you like guns! That's why you go to gun conventions; that's why you read gun magazines! None of you give a shit about home security. None of you go to home security conventions. None of you read Padlock Monthly. None of you have a Facebook picture of you behind a secure door.»
"In Australia, we had the biggest massacre on earth, and the Australian government went: 'That's it! NO MORE GUNS.' And we all went, 'Yeah, all right then, that seems fair enough, really.'"

Efectes secundaris de l'Ebola
Ebola side effects
Els recursos s'han centrat a lluitar contra les emergències. I ha mort molt personal sanitari. Així doncs, hi ha un munt d'infants no vacunats contra el xarampió i no prou tractament preventiu contra la malaria.
Recources have been focused in the fight against emergencies. And mnay health workers have died. Then, so, there are lots of kids unvaccinated for measles and not enought preventive treatment agaisnt malaria.

The international focus on the Ebola outbreak has raised concern that other killer diseases like malaria and measles have been neglected, writes the BBC's Anne Soy.

Story
Introduction
Informàtic de formació, m'hi vaig dedicar durant gairebé 10 anys. Ara estic en una etapa més centrat en el món dels jocs. Per exemple:
  • He creat jocs (alguns han guanyat premis, un ha estat publicat)
  • He fet conferències, xerrades, exposicions... sobre jocs
  • Faig tallers de jocs variats (aualé, toghızqumalaq, jocs de cordills, jocs tradicionals...)
  • He estat voltant per pobles ensenyant jocs motors tradicionals d'arreu del món
  • Participo en campionats, bàsicament d'aualé i toghızqumalaq (vaig ser al primer campionat del món, al Qazaqstan)
I bé, un altre dia explicaré més coses.
Bragging rights
He aparegut a diaris d'Antigua & Barbuda, Suïssa i el Qazaqstan :-)

Bon preu, especialment si compres un abonament, i bones pel·lícules.

No he visitat el museu, només la cafeteria. Una xocolata desfeta boníssima, igual que els melindros i els croissants. Un pèl car, això sí.
