The sleep cycle called REM and non-REM sleep is well known. On the other hand, Ultradian rhythms, which repeat this cycle even during waking hours, are not well known. And this is not recognized as an effective way to get rest.People repeat the sleep cycle even when they are awake. This timer will help you to grasp this body rhythm. It allows you to know your own rhythm. It allows you to rest effective and concentrate at a higher level in a less physically demanding way.USAGE:First, set your usual activity time and check "AUTO START".The timer will start automatically when the time comes. After that, work will be done according to the schedule of 90 and 20 minutes, but if you feel tired during the work, press "REST". From the point where you press break, the timer repeats the cycle of 20 and 90 minutes again.Whether you press break or not, the timer will end after the activity end time.MOTIVE:As a developer, I myself felt tired several times during the day, and as a result of ignoring fatigue and continuing to work, I realized that I could not work at all around the evening. We also found that this fatigue lasted about 20 minutes every 90 minutes.So, like an alarm clock, the timer starts at a fixed time every day, but when I feel tired or want to take a short break, feel free to press "REST" and work after a short break. I thought it would be convenient if there was an app that could restart.Through this timer, I would like to help you to grasp the rhythm of your body, take a rest effectively, and exert high concentration in a way that is less burdensome to your body.#concentration#ultradianrhythmSee below for a detailed explanation of the timer.https://tomo-mana.hatenablog.com/archive/category/20-90Timer
