![]() While the snooze button may make us feel that we are getting a little more much-needed sleep, it actually can create health problems and make it even harder to get up and face the day. This will allow users to wake gradually without switching from REM to non-REM sleep at a time when cortisol and testosterone are most needed. For people who struggle to get up in the mornings and need the gradual awakening of a snooze button, there are several alarm clocks that gradually increase light and noise. This will give them a longer time in REM sleep, with the attendant high cortisol and testosterone levels. ![]() People will fare better if they simply set their alarm clock for a slightly later time and get out of bed as soon as it wakes them. There are a few alternatives to using the snooze button. In addition, the cumulative effects of greeting the morning with low cortisol and testosterone day after day contribute to obesity, hypertension and a variety of other health issues. This induction of sleep inertia in snooze button enthusiasts can cause sufferers to have lower mental function and even a higher risk of accidents for several hours after they finally arise. ![]() When they wake again in a few minutes, they may suffer an unpleasant side effect of being woken up mid-sleep cycle: sleep inertia.Ĭortisol and testosterone levels fall quickly in non-REM sleep, back to less optimal levels for waking. People who hit the snooze button and fall back to sleep begin a new sleep cycle, in non-REM sleep. This REM sleep is stopped by your awakening to either turn the alarm off or hit the snooze button. When the alarm goes off, your brain is most likely engaged in REM sleep, which is the final phase of each sleep cycle. Testosterone is also important to the production of other sex hormones, such as estrogen.Ĭlearly, cortisol and testosterone are both important, but what does this have to do with the snooze button? The Snooze Button and Your Hormones Testosterone supports a healthy hormonal structure deficiencies of this androgen create diverse symptoms such as fatigue, weight gain and lowered sex drive. While it is widely considered a male hormone, it is important to both sexes. Testosterone also is crucial to good health. While cortisol can have detrimental effects in the high amounts associated with chronic stress, it is an important hormone for daily function in normal amounts. In addition, cortisol promotes a healthy metabolism and mental alertness. Cortisol reduces inflammation throughout the body, primes the immune system to react to pathogens and promotes the production of other hormones such as human growth hormone. ![]() While cortisol is widely viewed as a stress hormone, it is a very important biochemical in moderate amounts. ![]() When people naturally awaken according to their innate circadian rhythm, testosterone and cortisol are both high from these long REM periods, which supports wakefulness and alertness. As dawn nears, REM cycles become increasingly longer. In REM sleep, the brain kicks into gear, with an increase in brain waves and heightened production of hormones including cortisol and testosterone. In non-REM sleep, the brain has slower waves and performs many maintenance activities. We go through several cycles at night, alternating between non-REM and REM sleep. Humans are made to wake up slowly rather than at the call of an alarm. The Endocrine System and Your Sleep Cycle However, researchers of chronobiology warn that this extra sleep may be an actual health hazard rather than the blessing it seems. Since the invention of the snooze button in 1956, millions of people have opted on many mornings for just a few more minutes of sleep. ![]()
