Permanent Daylight Saving Time Would Be Awful for Our Circadian Rhythm
“Spring forward, fall back” could be no more, as Daylight Saving Time in the US could be made permanent. The issue resurfaced, as Americans say they are tired of moving the clocks twice a year and that we should just pick one. But did the government pick the wrong one?
The US has a long and complicated history with Daylight Saving Time — or what might be known better as “spring forward” time.
First enacted in 1918 during WWI as “wartime,” the measure was supposed to provide more daylight during working hours. Meanwhile, according to Michael Downing, author of “Spring Forward: The Annual Madness of Daylight Savings Time,” the US Chamber of Commerce also liked it, as workers with more daylight after work were likely to stop, shop, and spend money on their way home.
It was repealed only to be brought back again during WWII, so there would be more daylight during working hours.
After World War II, there was a chaotic period where states picked whichever time standard they wanted, until 1966 when the “Uniform Time Act” made six months of Standard Time and six months of Daylight Saving Time.
This brings us to today, where people have different opinions on Daylight Saving Time, but most Americans want the clock change gone. A 2019 AP poll showed that 71 percent of Americans would like to quit changing the clocks twice per year versus 28 percent who want to keep it the way it is.
Now, the US Senate just passed a measure that would again make Daylight Saving Time permanent. Some people like sunlight later in the evening, especially during the summer.
But many, including medical professionals and safety experts, argue that “springing forward” can be hazardous to your health.
Beth Ann Malow, a professor of neurology and pediatrics at Vanderbilt University writes, in ScienceAlert, “[m]oving the clocks forward is not just an inconvenience. It is a shock to the human body and nature.”
She and her co-authors reviewed data that linked Daylight Saving Time to increased strokes, heart attacks, and sleep deprivation in teenagers. She explains that falling back to Standard Time is, “relatively benign.” But by artificially moving time forward it messes with our internal circadian rhythm — our internal, natural clock. Sunlight also wakes us up and improves alertness in the morning.
“Exposure to light later into the evening delays the brain's release of melatonin, the hormone that promotes drowsiness. This can interfere with sleep and cause us to sleep less overall, and the effect can last even after most people adjust to losing an hour of sleep at the start of daylight saving time,” Malow said.
If this isn’t enough evidence against Daylight Saving Time, then we should be reminded that the US tried this in the 1970s and it failed.
In 1974, President Richard Nixon signed into law permanent daylight savings time. At first, it was widely popular, but that dropped precipitously after Americans had to deal with month after month of pitch-black mornings. It was reversed just 16 months later.
Now after everything we have learned and know after 100 years of this experiment. Will we go with natural Circadian Standard Time or Daylight Saving Time?
The Senate approved the “Sunshine Protection Act” unanimously. The measure will move to the house of representatives where it’s future is uncertain.
What Your Sleeping Position Reveals About You
I know it’s better for me as a woman to sleep on my back, arms at my side or resting on my torso peacefully. But no matter how hard I fight, the lure of sleeping in my favorite position—curled up on my side, legs tucked bent towards my chest—is just too much to resist. Sleeping in this position simply comforting to me, and sends me right to sleep, whereas sleeping on my back is a struggle. You might have a similar predicament, with this pose or a different one. Why is it like this? Why can’t we just automatically shift to the position that’s better for us?
Your sleeping position may actually have a connection with your personality and the way you think, feel and behave. There’s enough research to indicate that the posture adopted while sleeping has a lot to tell about the kind of people we are – introverted, confident, fun-loving, trusting, or something else.
It’s along the same vein as body language. How you sit, stand, or gesture when you’re awake can be unconscious signals, such as leaning away from someone you don’t like or crossing your arms during an argument. Sleeping positions are similar, and maybe even more revealing, as you have very little control of where you end up when you’re asleep, thus sending signals that are true to you without any filters.
Here are the top six most common sleeping positions, as well as a general overview of what they can mean:
- Fetal Position
What It Looks Like:
Curled up on your side.
What It Means:
This is the most common sleeping position (though it’s more common for women than men). According to research on this sleep subject, those who sleep in the fetal position were found to be sturdy and strong on first impressions but introverted and sensitive at heart when better known. These people are reserved and usually take time to open up to others but when they do, they are relaxed and comfortable. The outwardly tough appearance and brave face is actually a protection against the world. People with leg cramps or conditions like the restless legs syndrome generally experience leg discomfort, and tend to adopt the fetal position.
Health Considerations
If you’re like me and are constantly curling up to your left side, you may be increasing the pressure and stress on vital organs such as the liver, the heart, the stomach and the lungs. So, if fetus is your position of choice, take care to curl up on the right side of your body.
