![]() ![]() ![]() Myriam Juda PhD (Researcher at Simon Fraser University) et al Source With Standard Time, the start of the working day more or less aligns with sunrise and ends with sunset… As long as we can see natural light, our body clock aligns to the sun clock… isconnect between what time our body clock thinks it is and the actual local time has effects that are similar to chronic jetlag. DST also exposes people to more evening light, which further delays the biological clock and makes it more difficult to fall asleep… As experts in circadian biology, sleep, mental health and safety, we understand that removing the time change in favour of permanent Standard Time is the preferred option. When exposure to sunlight in the morning is reduced, our biological clock drifts later, making it harder to wake up and causing an increased mismatch between the body clock and local time (a condition called social jetlag). Our body’s internal biological clock needs exposure to morning light. Gene Block MS PhD (Chancellor of UCLA) & Johanna Meijer PhD (Neurology Professor at Leiden University Medical Center) Source xperts in biological rhythms and sleep unanimously agree that Standard Time year-round is the best option for public health and safety… If DST is kept year-round, sunrise would be later in the winter, leading to decreased exposure to morning sunlight… hildren will have to commute to school in the dark for about a third of the school year. There’s a wealth of data demonstrating that a lack of exposure to light leads to sleep and metabolic disorders, depression and cardiovascular disease, among other ailments… Permanent Standard Time is the only fair and viable option. Humans require adequate morning light so that our internal biological rhythms synchronize properly to the local time. The letters represent compass directions - N is north, WNW is west by northwest, and so on.ĭisappears represents where in the night sky the International Space Station will leave your field of view.Why Are Sunrises So Important? ack of morning light can have serious impact on our biological clocks, which control the body’s many daily rhythms, including our sleep and wakefulness cycle. ![]() This value, like maximum height, also is measured in degrees from the horizon. If you hold your fist at arm's length and place your fist resting on the horizon, the top will be about 10 degrees.Īppears is the location in the sky where the station will be visible first. The horizon is at zero degrees, and directly overhead is ninety degrees. It represents the height of the space station from the horizon in the night sky. Max Height is measured in degrees (also known as elevation). ![]() Visible is the maximum time period the space station is visible before crossing back below the horizon. This is the optimum viewing period as the sun reflects off the space station and contrasts against the darker sky. All sightings will occur within a few hours before or after sunrise or sunset. Time is when the sighting opportunity will begin in your local time zone. What does all this sighting information mean? ![]()
