When you go to bed at night and wake up in the morning, you probably don\u2019t give much thought to the time in between. Sometimes you have dreams and sometimes you don\u2019t. A night of sleep is made up of different stages. If you have sleep apnea or another sleep disorder, you may not be reaching all stages of sleep, and this can be harmful to your health. Read on to learn more about the stages of sleep and why they are important.<\/p>\n\n\n\n\n\n\n\n

Stage 1 \u2013 Light Sleep<\/h2>\n\n\n\n

When you first drift off to sleep, your eye movements begin to slow down, and your body will remain alert to a certain degree. However, outside stimuli could still easily wake you for these few minutes. This stage only lasts between five and ten minutes. It can be considered a transition period between wakefulness and sleep. If someone wakes up, they may not even realize that they had fallen asleep.<\/p>\n\n\n\n

Stage 2 \u2013 Fairly Light Sleep<\/h2>\n\n\n\n

During this time, you become less aware of your surroundings, your body temperature drops, and your breathing and heart rate become more regular. Your brain produces bursts of rapid, rhythmic brainwave activity known as \u201csleep spindles.\u201d The American Sleep Foundation <\/em>reports that people should spend approximately 50% of their sleep in this stage.<\/s><\/p>\n\n\n\n

Stage 3 \u2013 Deep Sleep<\/h2>\n\n\n\n

This stage causes your muscles to relax. Your blood pressure and breathing rate drop as well. This is when you are sleeping the deepest. You are less responsive to noise and activity around you. Deep, slow brain waves known as \u201cdelta waves\u201d emerge here. This is your body\u2019s chance to repair any muscles and tissues that were damaged during the day. This is also crucial to growth and development in children and teenagers.<\/p>\n\n\n\n

Stage 4 \u2013 REM Sleep<\/h2>\n\n\n\n

REM stands for \u201crapid eye movement.\u201d During this stage, your brain becomes more active, your body becomes relaxed, and your eyes move rapidly. This is the time of night when you are more likely to have dreams due to the increased brain activity.<\/p>\n\n\n\n

How Does Sleep Apnea Affect the Stages of Sleep?<\/h2>\n\n\n\n

If you have a sleep disorder, like obstructive sleep apnea<\/a>, that keeps you awake at night, you won\u2019t be spending as much time in stages 3 and 4 of the sleep cycle. Most of the sleep you have will take place in stages one and two. Your physical and mental health will suffer as a result. For instance, lacking sleep results in weaker immunity, higher blood pressure, memory issues, mood changes, and more. These issues will only get worse as time goes on.<\/p>\n\n\n\n

If you feel fatigued during the day or are experiencing other signs of sleep apnea, it is worth seeing a sleep dentist for treatment. This way, you can work toward quality, uninterrupted sleep.<\/p>\n\n\n\n
