Sleep experts speculate that this paralysis happens to prevent people from acting out their dreams. Researchers have found that everyone dreams, although not everyone remembers dreaming.ĭuring REM sleep, muscle paralysis occurs. Often, if you wake during REM sleep, you will remember your dreams. What is REM sleep? REM is an active sleep state when dreams occur. Once you start to practice good sleep habits, you can start to increase how much deep sleep you get each night. Children and adolescents typically spend more time sleeping in stage 3.Īlthough we only need a small amount of deep stage 3 sleep waves, this phase of sleep is critical for good health. For most adults, stage 3 is between 5% to 15% of our total sleep time. Overall, we spend far less time in stage 3 sleep than in stage 2. It’s difficult to awaken someone from stage 3 sleep. At this stage, our brain waves - called delta waves - are very slow. Stage 3 is when our deepest, most restorative slow-wave sleep occurs. Research suggests that sleep spindles help refresh our brains and make us more ready to learn. Spindles are brief bursts of brain activity that decline rapidly. What is a K complex? It is a large wave that can occur in response to stimuli, such as noises in your sleep environment. Your brain waves slow down as you relax into a deeper stage of sleep.Īccording to sleep researchers, two types of brain waves mark Stage 2 sleep: K complexes and sleep spindles. During stage 2, frequent awakenings are less common. Typically, most people spend 40% to 60% of their total sleep time in stage 2 sleep. Noises or disruptions can easily rouse you during the light sleep of stage 1. If you wake from stage 1 sleep, you may feel like you haven’t even been asleep. When drifting in and out of this stage of sleep, you can have a falling sensation. Your eyes move slowly, and your body may experience some mild jerks or spasms. Your body starts to relax and prepare you for the next sleep stage. Stage 1 is the transition between sleep and wakefulness. Instead, we actually go back through stage 2 and stage 1 before finally entering the REM sleep phase.Įach sleep cycle takes between 90 and 110 minutes, and we go through several sleep cycles each night. However, we don’t go from stage 3 sleep to REM sleep. We begin with stage 1 sleep, then pass through stages 2 and 3. While sleeping, we journey through each of these sleep phases. REM stands for “rapid eye movement.” There are three non-REM (NREM) sleep cycle stages as well. You may have heard of REM sleep, which is when vivid dreams occur. Seek out a mattress with good airflow that helps you stay cool even on hot nights. Look for mattresses that alleviate pressure on your back, hips, and shoulders. What mattresses are best? Find a mattress that is breathable, supportive and pressure-relieving that can adapt to your body and sleep positioning. Set yourself up for success by making your bedroom the ideal sleeping temperature. Know Your Ideal Sleep TemperatureĪlthough comfort levels vary, most adults sleep well if the temperature is between 60 and 67 degrees. Learn more about how electronics affect sleep. Being mindful of your electronic use is critical if you want to sleep more deeply. Plus, blue light can disrupt your circadian rhythm and diminish melatonin production. During the day, blue light creates more alertness and energy, but it can be overstimulating at night. Avoid Electronics Before BedĪvoid watching TV or using laptops, computers, tablets, and phones near bedtime.Įlectronics emit artificial blue light that has short wavelengths. Caffeine can reduce sleep quality, especially when taken in the evening around bedtime. Avoid CaffeineĪvoid caffeine in the evenings. Experiment with an exercise schedule to see what works best for you. Research shows that people who do cardio regularly get more deep sleep during the night. Keep these sleep patterns consistent, even on weekends and vacations. Go to bed and wake up at the same time each night. Many factors can disrupt your circadian rhythm and prevent you from getting a good night’s sleep.īut you can establish a sleep schedule that trains your mind and body to stay in rhythm. Your body has an internal clock, known as its circadian rhythm, that controls your sleep-wake cycle. Here are some helpful tips to help you sleep deeply each night: 1. During the deepest stage of sleep, your body and brain revitalize and promote better health, learning, and memory. Even if you’re getting the suggested seven to nine hours of sleep per night, you could find out how to get more deep sleep. But a pattern of sleep deprivation can cause health problems. A restless night or two may throw you off.
