Daylight Saving Time is a practice that was created over 100 years ago to increase the amount of workable hours during summer months.  By artificially "extending" day into the evening, the amount of literal daylight one had to work was increased exponentially.

Today, this practice is absolutely foolish, as agricultural workers are the vast minority among all working Americans,  totaling 1~2% in most states,  less so in others.

There are several medical complications that have been attributed to the practice of Daylight Saving Time such as increase in heart attacks.  The impacts of DST are likely related to our body's internal circadian rhythm, the still-slightly-mysterious molecular cycles that regulate when we feel awake and when we feel sleepy, as well as our hunger and hormone production schedules.

Light dictates how much melatonin our bodies produce. When it's bright out, we make less. When it's dark, our body ramps up synthesis of this sleep-inducing substance.

Just like how jet-lag makes you feel all out of whack, daylight saving time is similar to scooting one time zone over for a few months.

The problems with DST are the worst in the spring, when we've all just lost one hour of sleep. The sun rises later, making it more difficult to wake in the morning. This is because we reset our natural clocks using the light. When out of nowhere (at least to our bodies) these cues change, it causes major confusion.

Like anytime you lose sleep, springing forward causes decreases in performance, concentration, and memory common to sleep-deprived individuals, as well as fatigue and daytime sleepiness.

Night owls are more bothered by the time changes than morning people. For some, it can take up to three weeks to recover from the sleep schedule changes, according to a 2009 study in the journal Sleep Medicine. For others, it may only take a day to adjust to this new schedule.

All in all, we should allow our bodies to adapt to time changes just as they always have.  With the initial point of DST having become entirely unnecessary in the states which it is now still in effect, it is the most logical path to make it non-standard throughout America.
