![]() ![]() Reduce your dose next time to see if that helps. If you’ve gotten a full night’s sleep (6+ hours), but still feel groggy when you wake, you may be taking too large of a dose of melatonin. The morning after taking melatonin, you should wake up feeling rested, relaxed and invigorated. It’s formulated with an optimal level of melatonin for no next day grogginess,* shown to help support your natural sleep cycle, and a proprietary blend of botanicals, including chamomile and lavender. ![]() If you’re looking for a drug free approach, the sleep experts at Vicks also designed ZzzQuil PURE Zzzs Melatonin as a sleep supplement that will help you fall asleep naturally* so you can take on your tomorrow. Both contain diphenhydramine, an antihistamine known to help treat occasional sleeplessness so you can fall asleep in as little as 20 minutes with a non-habit forming sleep-aid. If you suffer from occasional sleeplessness, an over-the-counter sleep medication such as ZzzQuil Liquid or ZzzQuil LiquiCaps can help. It is relatively easy to wake someone from stage 1 sleep in fact, people often report that they have not been asleep if they are awoken during stage 1 sleep.A healthy adult requires 7-9 hours of sleep per night, and sleeping less than this can reduce the number of REM sleep cycles. Theta waves are even lower frequency (4–7 Hz), higher amplitude brain waves than alpha waves. ![]() As an individual continues through stage 1 sleep, there is an increase in theta wave activity. This pattern of brain wave activity resembles that of someone who is very relaxed, yet awake. The early portion of stage 1 sleep produces alpha waves, which are relatively low frequency (8–13Hz), high amplitude patterns of electrical activity (waves) that become synchronized. In terms of brain wave activity, stage 1 sleep is associated with both alpha and theta waves. In addition, stage 1 sleep involves a marked decrease in both overall muscle tension and core body temperature. During this time, there is a slowdown in both the rates of respiration and heartbeat. Stage 1 sleep is a transitional phase that occurs between wakefulness and sleep, the period during which we drift off to sleep. The first stage of NREM sleep is known as stage 1 sleep. In this section, we will discuss each of these stages of sleep and their associated patterns of brain wave activity. The first three stages of sleep are NREM sleep, while the fourth and final stage of sleep is REM sleep. In contrast, non-REM (NREM) sleep is subdivided into three stages distinguished from each other and from wakefulness by characteristic patterns of brain waves. Brain waves during REM sleep appear very similar to brain waves during wakefulness. Rapid eye movement (REM) sleep is characterized by darting movements of the eyes under closed eyelids. Sleep can be divided into two different general phases: REM sleep and non-REM (NREM) sleep. These changes in brain wave activity can be visualized using EEG and are distinguished from one another by both the frequency and amplitude of brain waves. Instead, sleep is composed of several different stages that can be differentiated from one another by the patterns of brain wave activity that occur during each stage. Differentiate between REM and non-REM sleep. ![]()
