Blue light can be harmful

Your Laptop And Phone Are Dangerous

Ditch the electronics before bed and read a book instead.

As a college student, I spend at least half a day on my laptop in addition to my iPhone. Nowadays, children as young as 3 years old are watching shows on the mini tablets at the dinner table as they wait for their parents to finish their meal. It has become a requirement for some elementary and high schools to possess an iPad – not to mention, adolescents spend ample time on their devices for leisure. Most professions require proficient computer skills, which include programming, organizing spreadsheets, and many more. With this recent lifestyle change in which separation from electronic screens is impractical, it is important to consider how to minimize the negative effects such technology can have on our health.

Although increasing screen time inevitably promotes the sedentary lifestyle, a greater concern is the detrimental effects on our eyes. Computer monitors, tablets, and smartphones are sources of blue light, which is a component of light characterized by shorter wavelengths (400-490 nm) and greater energy. In 2014, researchers found that the use of electronic devices "before bedtime prolongs the time it takes to fall asleep, delays the circadian clock, suppresses levels of the sleep-promoting hormone melatonin, reduces the amount and delays the timing of REM sleep, and reduces alertness the following morning." In addition, they stated that the "Use of light-emitting devices immediately before bedtime also increases alertness at that time, which may lead users to delay bedtime at home." Detrimental effects on sleep have been associated with a number of problems such as obesity, depression, and diabetes.

A study in 2011 reported that compared to adults, children's eyes absorb blue light more when exposed to electronic screens. This is particularly problematic because an increasing number of children now own these devices at a younger age.

Some of the ways in which blue light can be avoided are to allocate a restricted amount of time on the laptop and the phone. In many circumstances – such as being a student or working full-time at an office desk – a full-day exposure to screens can be inevitable. As an alternative, blue light reflective glasses appears to have worked for some, and laptop and smartphone devices can have "night shift modes" where blue light emission is minimized.

More research is needed on the relationship between blue light and eye health for any conclusive results. However, I realize that it is always better to be safe than sorry, especially when it comes to my health.

9 Reasons You're Still In Love With Tim Riggins In 2019

Clear eyes. Full hearts.

If you're a Friday Night Lights fan, you know very well who Tim Riggins is. And if you've never seen the show, he's basically just the bad boy football star and sensitive hottie of your dreams, all wrapped into one heart-throbbing package. If you haven't already fallen under the Tim Riggins spell, you're about to...


1. He's the star running back of the Dillon Panthers.

Basically every girl who has walked this earth has fantasized about having that cliche football relationship. No shame. #33 on the field, #1 in my heart.

2. He's actually really sensitive.

Tim Riggins may seem hard and dysfunctional on the outside, but he's really just a big softie. He's no JD McCoy, who grew up lavishly and extremely fortunate; Tim had a rough upbringing. He and his brother, Billy, had to work hard all by themselves just to stay above water, which is most likely what keeps him so grounded and humbled.

3. He loves kids.

Tim didn't even think twice about taking his neighbor under his wing when he moved in next door. And for some reason, there's just somethin' about cute boys holding babies that makes us girls swoon.

4. He's genuine and honest.

Sure, maybe he took advantage of his football-star status and slept with most of the rally girls, but once he fell in love with Lyla we saw his compassionate side. (You probably envied Lyla and maybe even hated her for a while because of it...I know I did.)

5. He knows how to have a good time.

It's 5 o'clock somewhere.

6. He's a family man.

Tim took the blame for his brother's crime and went to prison for it...if that's not loyalty then I don't know what is.

7. He's affectionate.

If you either hate Lyla or you want to be Lyla or a combination of the both, you are not alone.

8. He's protective.

Probably the only time you've ever wanted to be in a tornado was when you watched the episode where he shielded Julie from flying debris.

9. He's beautiful.

You're welcome for blessing you with this GIF.

May you all find your own Tim Riggins. Amen.

Poetry On The Odyssey: It's a Girl

An ode to the little girl raised to be insecure.

They raise little girls to be insecure

Little girls grow to be big girls

People always ask big girls why they're so insecure

Big girls aren't quite sure

Day after day the big girl can't keep up

She's exhausted

Her soul feels worn

The big girl learns to grow hard

In a way, she's a bit stronger

People call her a bitch

Bitch

What is that?

How can she let that affect her

It's simply the only way to be her

She mourns that little girl

Hoping that one day

She'll be strong
