Do you have moments where you feel like you could go to sleep at any time of day? How about an experience with insomnia? Have you ever used sleep aides to help you dose off? Kevin, Lo and Sully discuss their sleep cycles, why they use sleep aides on a night basis and more in "No Sleep Till Long Beach". Lo is back home from heading to Long Beach, NY and she joins the boys to talk about the best thing ever, SLEEP! She uses her Apple Watch to track her sleep habits and how much REM sleep she gets. Kevin talks about the stages of sleep - Stage 1 Stage one of sleep, also known as the transitional phase, occurs when one finds themselves floating in and out of consciousness. During this NREM stage, you may be partially awake while your mind begins to drift off. This period of drowsiness eventually leads to a light sleep. This is also the time when the muscles jerk, followed by a falling sensation that jolts you back into consciousness. This experience is known as hypnic myoclonia. After winding down in stage one, your sleep cycle will slip you into stage two. Stage 2 Almost 50% of the time spent asleep over the course of the night is spent in stage two. Stage two is also a non-REM phase and is one of the lighter stages of sleep. Even though it is a light stage, the heart rate begins to slow and the core body temperature decreases. During stage two, eye movement stops and brain waves slow with the occasional burst of waves called sleep spindles. Stage two can also be characterized by the unstructured periods that alternate between muscle tone and muscle relaxation. Stages 3 & 4 Stages three and four are characterized as the deep stages of sleep, and are often the hardest to wake up from. If you try to wake someone up when they are in stages three or four, they will most likely be disoriented and groggy for minutes after they awake. Stages three and four are often grouped together because they are the periods of slow wave sleep (SWS). Slow wave sleep is a NREM phase of sleep, and is the deepest sleep that your body enters throughout the night. It is called slow wave sleep because the brain waves slow to what are known as delta waves with the occasional faster wave. As the body moves from stage three to stage four, the number of delta waves increase and the faster waves decrease. In addition to the deep sleep caused by the delta waves, blood pressure drops even further, and breathing becomes deeper, slower, and more rhythmic. During slow wave sleep there is no eye movement, and the body becomes immobile. However, even though there is no muscle movement, the muscles still have the ability to function. Stages three and four of sleep are extremely rejuvenating to the body. During slow wave sleep, hormones are released that aid in both growth and appetite control. The growth hormones help to replenish muscles and tissues that were exerted over the course of the day, and the appetite controlling hormones help limit feelings of excessive hunger the following day. These hormones are essential to the development of a strong body and help control unnecessary over-eating. In addition to the release of critical hormones, the blood flow to the muscles increases, providing restorative oxygen and nutrients. Stage 5 Stage five is the only stage of rapid eye movement (REM), and is unlike any other sleep phase because the brain is bursting with activity. Most adults spend about 20% of sleep in REM, while infants spend almost 50%. During non-REM sleep, the mind rests while the body heals, but in REM sleep the mind energizes itself while the body is immobile. REM sleep is called as such because the eyes dart in various directions while the limbs and muscles are temporarily paralyzed. Breathing becomes shallower and irregular while the heart rate and blood pressure rise from the levels they were in previous stages. Most dreaming takes place in stage five as a result of heightened, desynchronized brain waves, almost similar to being awake. This stage of sleep revitalizes the brain, supporting sharp and alert daytime function. Individuals begin waking up at the end of stage 5. Upon waking up, an individual’s core body temperature begins to rise in order to prepare the body for the activity of the day ahead. If you're having any issues sleeping, the crew gives some great alternatives to help get you that good nights rest you need. Enjoy the episode, we're going to nap!
