This Is What Happens to Your Body the Longer You Go Without Sleep

A friend and co-worker in high school was trying to work full time, school full time, and still keep an active social life.  They fell asleep at the wheel, went off the road, crashing (in both senses of the word).  Injuries were severe – when I last saw them, they had intelligence and vocabulary but struggled to say the words.  I haven’t seen them in years, but do remember seeing them on Facebook.  It was really rough, getting the news about the crash while at work.

Please don’t let that happen to you or someone you know.  I’ve had close calls, stupidly thinking I could “push through it”.  Even today, I have time where I learn that I haven’t been sleeping as much or as well as I should be.

Do You Really Need a Good Night’s Sleep to Exercise Well?

“Get a good night’s sleep” is classic advice before a big race or event. But if you stayed up late picking out your best shoelaces and then woke up early to make it to the start line on time, have you ruined your chance at a good performance?

The answer?  It depends™, on the activity.  There’s a lot of strategy in cycling, so I’m not that inclined to believe that cycling is the same as running.

The classic runners rule is also the triathletes rule.  Partly because lots get up between 2-4 AM to eat breakfast before going back to bed to actually get up for the triathlon.

Dying Your Hair May Not Be as Safe as You Think

The basic chemistry of hair dyes has changed little over the last century, but what do we know about the risks of colouring our hair, and why do we do it?

Every two months Barclay Cunningham goes through a process that begins with taking an antihistamine tablet. After a few hours, she smears a thick layer of antihistamine cream across her forehead, around her ears and over her neck. Finally, she shields the area with ripped-up plastic carrier bags.  All this so she can dye her hair.

It didn’t start out this bad. Cunningham coloured her hair for a decade without any problems. Then, one day, she noticed that the skin on her ears was inflamed after she’d dyed her hair. She fashioned plastic bag earmuffs and carried on colouring. But the allergic reaction persisted, so her precautions became more elaborate. Now if she dyes her hair without these measures, she gets an itchy, blistery, pus-filled rash that lasts for weeks.

I have always been startled by how many people I know eat organic vegetables, drink only from glass, use only vinegar to clean their houses… and dye/colour their hair.

Study: Sharing Dessert Reduces Guilt

Normally, people do not enjoy being forced to do something. People also do not enjoy the guilt that comes with doing something that is bad for them. Surprisingly, these two wrongs seem to make a right: when people are compelled to engage in vices, they feel better than when they freely choose the vice for themselves. According to a new paper in the Journal of Consumer Research, persuading a friend to share a dessert removes the burden of choice from them, reducing their feelings of guilt and making them less conflicted about the decision.
