The first three are NREM - meaning non-rapid eye movement stages - while the final stage is REM sleep.\n\nStage one, also known as NREM stage one, is the transition between wakefulness and sleep. During this stage, body temperature drops and heart rate slows. Your brain waves become slower and more regular as you drift off to sleep.\n\nStage two (NREM stage two) is characterized by deeper relaxation. This stage typically lasts for about 20 minutes before transitioning into deep sleep.\n\nIn deep-sleep (NREM stage three), your breathing becomes slow and regular while your muscles relax even further. This stage helps restore energy levels and promote tissue growth and repair throughout the body.\n\nFinally, REM sleep occurs when dreaming takes place; during which, your eyes move rapidly beneath closed eyelids while other parts of the body remain still due to an increase in brain activity associated with dreaming.","2c28d5c3-c428-4945-8550-7ec02102d634",[49],{"id":50,"data":51,"type":52,"version":25,"maxContentLevel":29},"ed0d876e-b204-4656-bf79-2494a53f7304",{"type":52,"reviewType":29,"spacingBehaviour":25,"multiChoiceQuestion":53,"multiChoiceCorrect":55,"multiChoiceIncorrect":57},11,[54],"What type of sleep is associated with an increase in brain activity and rapid eye movement?",[56],"REM sleep",[58,59,60],"NREM sleep","Deep sleep","Light sleep",{"id":62,"data":63,"type":25,"maxContentLevel":29,"version":26,"reviews":67},"4aedbf89-5465-4611-97d2-ff8454f3d0ff",{"type":25,"title":64,"markdownContent":65,"audioMediaId":66},"Stage 1: The Transition from Wakefulness to Sleep","Stage one of the sleep cycle is a crucial transition period between wakefulness and sleep.

Exposure to light during the day helps keep us alert and energized, while darkness at night signals to our bodies that it’s time for sleep. This is why we often feel more tired when it gets dark outside or if we stay up late into the night.\n\nThe SCN in the hypothalamus is particularly sensitive to light, which helps regulate melatonin production and other hormones associated with sleep-wake cycles.\n\nFor example, exposure to bright lights during the day can suppress melatonin levels and make us feel more awake, whereas dim lighting at night can increase melatonin production and help us fall asleep faster. \n\n ![Graph](image://96d5c4a3-e7bd-45ff-8741-9e9c94d9e138 \"Someone using their phone in the dark\")\n\nBad news if you’re reading this late at night as blue light from electronic devices such as smartphones has been shown to disrupt natural circadian rhythms. This light suppresses melatonin levels even further than regular indoor lighting does.\n\nTherefore, to ensure quality sleep, it’s important to limit exposure to blue light before bedtime by avoiding screens for several hours prior or using special glasses designed specifically for this purpose.\n\n","895f367c-b146-4420-ab7e-b684d1f40b60",[284],{"id":285,"data":286,"type":52,"version":25,"maxContentLevel":29},"8460df50-0347-434a-8c45-eda45fa4c6dc",{"type":52,"reviewType":26,"spacingBehaviour":25,"binaryQuestion":287,"binaryCorrect":289,"binaryIncorrect":291},[288],"What part of the brain is particularly sensitive to light and helps regulate hormones associated with sleep-wake cycles?",[290],"The SCN in the hypothalamus",[292],"The PFC in the hypothalamus",{"id":294,"data":295,"type":26,"version":25,"maxContentLevel":29,"pages":297},"5101214c-c1cd-434f-a18e-23cacaee73d4",{"type":26,"title":296},"Modern Life and Circadian Rhythms",[298,359,374],{"id":299,"data":300,"type":25,"maxContentLevel":29,"version":25,"reviews":304},"5d9433e9-6aa0-4862-87f3-9d4901ea5abf",{"type":25,"title":301,"markdownContent":302,"audioMediaId":303},"The Impact of Modern Life on Circadian Rhythms","Modern life has drastically changed the way we interact with our environment, and this can have a significant impact on our circadian rhythms.\n\nShift work, for example, requires individuals to stay awake during hours when their bodies would normally be sleeping.

Inadequate sleep leads to higher cortisol levels, which can have negative effects on both mental and physical health, including weight gain, poor immune function, and increased risk of heart disease.\n\nGetting enough high-quality sleep can help reduce stress and promote a sense of calm and well-being. During sleep, the brain processes and organizes information from the day, reducing the cognitive load and allowing the mind to rest and recharge.\n\nAdditionally, sleep plays a role in the release of neurotransmitters such as serotonin, which help regulate mood and improve mental health.\n\n ![Graph](image://976b979b-5aa5-4575-8809-eeda0843cde2 \"Structure of serotonin\")","e349e252-5980-480a-a691-760d5794f142",[1478],{"id":1479,"data":1480,"type":52,"version":25,"maxContentLevel":29},"1f0499be-8629-41bf-ac35-19944fcca9d3",{"type":52,"reviewType":26,"spacingBehaviour":25,"binaryQuestion":1481,"binaryCorrect":1483,"binaryIncorrect":1484},[1482],"What neurotransmitter helps regulate mood and improve mental health?",[545],[1485],"Dopamine",{"id":1487,"data":1488,"type":25,"maxContentLevel":29,"version":25},"31dbb4bf-342e-4a52-ba29-41a2a5294513",{"type":25,"title":1489,"markdownContent":1490,"audioMediaId":1491},"The Impact of Sleep on Cognitive Functioning","Sleep is essential for cognitive functioning, with research showing that those who get enough restful sleep are better able to concentrate and remember information than those who don't. \n\n ![Graph](image://7170aa12-e832-47b8-b3dc-085278f03ffb \"Students being active in class\")\n\nPoor quality sleep has been linked to impaired memory recall and difficulty focusing.

Additionally, keep the temperature of your room between 60-67°F (15-19°C) as this can help you fall asleep faster and stay asleep longer. \n\nCreate a relaxing atmosphere before you sleep, you could use essential oils, candles, or soft music to create a calm ambiance. When it is time to sleep, avoid screens, the blue light emitted by devices can interfere with sleep, so avoid using them for at least an hour before bed.\n\nLastly, choose comfortable bedding.
