•     "The National Sleep Foundation understands the appeal of having longer, brighter evenings. Permanent DST may seem like you get more hours per day of sunlight, but in reality, the plan just shifts total bright hours from when we need them in the morning to later in the afternoon. DST essentially fights the natural order of our circadian rhythms, the natural sleep/wake process in our bodies. Our circadian rhythms rely on bright natural light in the morning to wake us up and to synchronize important biological processes, and dimmer light in the evening to make us sleepy and ready for bed. It’s unhealthy to alter our bodies’ sleep schedule to have more daylight hours in the evening. Morning darkness and evening light are counter to NSF recommendations for being your Best Slept Self™. A consistent year-round time system is agreed upon by NSF and other leading sleep and science-based organizations and NSF released a Position Statement on permanent Standard Time last year. Our sleep-wake cycle does not adjust to annual clock change, leading to negative effects on health and safety including cardiovascular disease, motor vehicle crashes, mood changes and depression, and metabolic abnormalities."

Evidence supports the distinct benefits of ST for health and safety, while also underscoring the potential harms that result from seasonal time changes to and from daylight saving time (DST)."
