Sleepytime calc6/10/2023 ![]() ![]() Keep your phone or tablet for reading, but you might want an app that dims the screen for bed viewing so the images aren't as likely to wake you up.Īnd practice good bed habits: make your bed every morning when you wake up and don't sit or lay on the bed until you're ready to sleep.Īnd hey, if it helps great, because with bad sleep, you can use all the help you can get! So if your alarm disrupts a sleep cycle, ok to can be difficult.Īlso, don't forget to just lay down in bed with the rest of your electronics off. The theory behind this app comes from the following example: have you ever woken up too early and felt really awake, only to fall back asleep and wake up later, feeling groggy? It's theorized that waking up during one of your "sleep cycles" can disrupt your restful sleep. Or I can set up the time I want to wake up and it'll tell me when to get to bed to have the number of sleep cycles desired. But I also set one or two frivolous alarms before the final alarm to have the satisfaction of "ignoring" them and feeling like I can sleep in longer.Īnother supplement I started trying was to get a sleep calculator that you can set what time you're going to bed and count the number of cycles I want. I eventually decided to actually try it and it really worked (and has since) to correct my poor sleep. Instead of setting a time I wanted to sleep, I would instead set a time that I would, no matter what, pull myself out of bed. Then it was recommended to me by a doctor to take the stress off going to sleep by stressing more when I woke up. Long-term exposure to light at night in shift work has even been associated with an increased risk of breast and prostate cancers.I used to have trouble sleeping and couldn't find a good medicine to help. It is likely that disruption of the clock contributes not only to sleep problems, but the development of depression, metabolic disorders and cardiovascular disease. "As our clocks are very sensitive to blue light, the use of tablets and smartphones at night can be disruptive. "Problems arise when we disrupt our clock with light at night, essentially tricking our clock into thinking it is day when it is night," Cain explains. This means that when we have computer screens and televisions and bright lights on into the evening (something 54 per cent of Australians do, according to a new survey by Koala mattresses), we confuse our SCN. ![]() When there is less light – like at night – the SCN tells the brain to make more melatonin so you get drowsy." "Since it is located just above the optic nerves, which relay information from the eyes to the brain, the SCN receives information about incoming light. "The body's master clock, or SCN, controls the production of melatonin, a hormone that makes you sleepy," explains the National Institute of General Medical Sciences. There are a couple of simple ways to rest easier. This is most obvious in situations where the clock is disrupted, like in jet lag and shift work," Cain explains. When you are sleeping at a non-optimal time, sleep suffers. If you sleep at the right biological time, you'll get optimal sleep. "Sleep quality depends very much on the timing of sleep relative to your internal clock. For starters, it's not just about REM sleep, it's about when we sleep. Trying to calculate a bedtime based on sleep cycles is problematic for several reasons. Luckily, I don't think many people would actually follow the advice." It's potentially harmful, if the advice in that article gets around. "Sleeping an extra hour, but feeling a bit groggier when waking would most likely be better for your alertness across the waking day. This is likely to be a temporary benefit. In REM, the brain is about as active as it is when awake, so it may feel easier to wake. "I'd definitely disagree that it is more important to wake out of REM than to get more sleep. "It is easier to wake out of REM, but the advice on when to go to bed is terrible," says Cain, a senior lecturer whose research focus is sleep and circadian rhythms. ![]()
