The Role Of Genes And Neurotransmitters

Chemical signals to sleep;;;;;

Clusters of sleep-promoting neurons in many parts of the brain become more active as we get ready for bed.; Nerve-signaling chemicals called neurotransmitters can switch off or dampen the activity of cells that signal arousal or relaxation.; GABA is associated with sleep, muscle relaxation, and sedation.; Norepinephrine and orexin keep some parts of the brain active while we are awake.; Other neurotransmitters that shape sleep and wakefulness include acetylcholine, histamine, adrenaline, cortisol, and serotonin.

Sleep studies

Your health care provider may recommend a polysomnogram or other test to diagnose a sleep disorder.; A polysomnogram typically involves spending the night at a sleep lab or sleep center.; It records your breathing, oxygen levels, eye and limb movements, heart rate, and brain waves throughout the night.; Your sleep is also video and audio recorded.; The data can help a sleep specialist determine if you are reaching and proceeding properly through the various sleep stages.; Results may be used to develop a treatment plan or determine if further tests are needed.;

    Optimize Your Body Temperature

    Body and room temperatures play a crucial role in helping to fall asleep and get more deep sleep in the early parts of the night. Bodys core temperature fluctuates naturally during the day and it reaches its highest point in the late afternoon after which it begins to cool down.

    According to the National Sleep Foundation , the best temperature for sleep is approximately 6067°F . Temperatures over 71°F are likely to cause impaired sleep quality, which is also true for a too cold environment . Sleeping in too hot of a bedroom deters REM sleep especially, but can also diminish deep sleep. People with sleep-onset insomnia have delayed temperature rhythms. Using a sauna or exercising too late may interfere with sleep-onset and deteriorate deep sleep. People with difficulties staying asleep often have nocturnally elevated core body temperature. Therefore it is also crucial too cool down your body before going into sleep.

    For example, yours truly sleeps in a bedroom where the window is always open and the average temperature is around 15 C in winter and around 19 C during summer time. One anecdote also comes from yours truly from last summer when it was super hot five weeks in a row: the room temperature was around 2627°C and during that time my deep sleep was about 40% below average.

White noise can be created by anything from a fan to a white noise;machine all that matters is that it provides a soothing, ongoing backdrop for restful sleep.

    People looking to increase deep sleep may also benefit from exposing themselves to pink noise. Creating a deeper, more resonant tone than white noise, pink noise;is a sonic hue that can be heard in steady raindrops, heartbeats, and the rustle of leaves.

    There are four sleep stages; one for rapid eye movement sleep and three that form non-REM sleep. These stages are determined based on an analysis of brain activity during sleep, which shows distinct patterns that characterize each stage.

    Sleep Stages
    REM Sleep10-60 minutes

    The breakdown of a persons sleep into various cycles and stages is commonly referred to as sleep architecture. If someone has a sleep study, this sleep architecture can be represented visually in a hypnogram.

    The classification of sleep stages was by the American Academy of Sleep Medicine . Before that, most experts referred to five sleep stages, but today, the AASM definitions of the four stages represent the consensus understanding of the sleep cycle.

    Tracking Sleep Through Smart Technology

    Millions of people are using smartphone apps, bedside monitors, and wearable items to informally collect and analyze data about their sleep.; Smart technology can record sounds and movement during sleep, journal hours slept, and monitor heart beat and respiration.; Using a companion app, data from some devices can be synced to a smartphone or tablet, or uploaded to a PC.; Other apps and devices make white noise, produce light that stimulates melatonin production, and use gentle vibrations to help us sleep and wake.

    Measuring Deep Sleep With Oura Ring

    The best way to measure your deep sleep is with a sleep tracking technology like the Oura Ring.; Sleep tracking is an increasingly popular technology that can track your:

    • Sleep duration: They track the period that you are inactive when you fall asleep and wake up in the morning.
    • Sleep quality: They track interrupted sleep and show you how much youve tossed and turned during your sleep.
    • Sleep phases: They track how deep youve slept, when and for how long youve achieved different sleep phases, and if youve experienced REM sleep. This is the function that you need to check your deep sleep.
    • Environmental factors: They track the light in your bedroom or temperature that may affect your sleep.
    • Lifestyle factors: In some trackers, you may enter information about your daily activities that may affect your sleep, including your diet, exercise, or stress levels.

    There are a variety of wearable trackers on the market. Most of them are strap-on you wear on your wrist similar to a watch. Other trackers can be placed by your pillow or on your bedside table. There is one sleep tracker I particularly love, personally use, and recommend, though. It is the Oura Ring. Yes, its a small ring that looks like you are wearing a regular ring. Nobody will know that you are wearing a sleep tracker. Since it wraps around your finger precisely, it is incredibly accurate and more detailed than most other trackers

    Substance Use And Withdrawal

    • Benzodiazepines
    • Opioid medications

    Caffeine is the stimulant found in coffee, tea, and many other beverages. Caffeine may reduce deep sleep. This effect can even happen hours after you consume it.

    Benzodiazepines, the class of tranquilizer drugs that includes Valium , may also reduce deep sleep. Opioid medications can have the same effect.

    Some medications may increase deep sleep. These include:

    • Lithobid

    Trazodone is an older antidepressant that is often used as a sleep aid. This drug appears to interact with histamines, compounds released during allergic reactions. This seems to increase deep sleep.

    Some sleep aids don’t seem to impact deep sleep one way or another. These non-benzodiazepine sleep aids include:

    • Ambien, Zolpimist, Edluar

    How Much Deep And Light Sleep Do Children Need

    Deep Rem Sleep Inducing

    Babies and children need more sleep than adults. Babies need the most, spending about 16 of every 24 hours asleep. Approximately 50 percent of their slumber is spent in the REM stage, while the other 50 percent is divided between stages 1 through 4 and NREM sleep that cycles between light and deep.

    As children grow older, the amount of sleep they need varies:

    • toddlers: 11 to 14 hours
    • preschoolers: 10 to 13 hours
    • school-aged children: 9 to 12 hours
    • teens: 8 to 10 hours

    With enough sleep that appears to be restful, its likely that the light, deep, and REM ratio is exactly where it should be in young people.

    If theyre having trouble with falling asleep, staying asleep, or sleeping well, or if they are sleeping way too much for their age, children may be irritable, could have learning and memory problems, or may be more susceptible to illness.
