If you’ve ever had trouble sleeping, you know how debilitating it can be the following day. Work becomes an insurmountable task, everyday chores become a real slog, and life loses its luster. Yet, consistently failing to get some much-needed shut-eye over extended periods can create even more problems and develop a nasty <\/span>circadian rhythm disorder<\/span>.<\/span><\/p>\n In this article, we\u2019ll take a closer look at what makes our \u201cinternal clock\u201d tick, its effects on our psyche, and how best to get out of this vicious cycle of sleepless nights and sleepy days.<\/span><\/p>\n So, let\u2019s not waste any more time and get straight to it!<\/span><\/p>\n It\u2019s a self-sustaining autonomous process where a person\u2019s body secretes hormones that regulate multiple functions at 24-hour intervals. The term \u201ccircadian\u201d derives from the Latin <\/span>circa dies<\/span><\/i>, which means \u201cabout a day.\u201d<\/span><\/p>\n Our internal clock is influenced by daylight and darkness at night, which can be reflected in an individual\u2019s shifting energy levels.<\/span><\/p>\n That said, different people have <\/span>different circadian rhythms,<\/span> which can be shorter or longer than 24 hours.<\/span><\/p>\n Our \u201cinternal clock\u201d is located in our brains. Specifically, our hypothalamus. One part of it \u2014 the suprachiasmatic nucleus (SCN) \u2014 is responsible for managing our entire <\/span>circadian rhythm<\/span><\/a>.<\/span><\/p>\n The SCN secretes hormones that control various bodily functions throughout the day. Some of the most important ones are:<\/span><\/p>\n Hence, a <\/span>circadian rhythm sleep-wake disorder <\/span>will affect all of the above, not just sleep-wake time. That is why it\u2019s <\/span>vital <\/span><\/i>to restore balance as soon as possible. Likewise, any damage to the SCN will impair every other rhythm it controls, such as the diurnal, ultradian, and infradian.<\/span><\/p>\n The most frequently made argument to explain our internal clock is the link between <\/span>circadian rhythm<\/span> and<\/span> sleep.<\/span>\u00a0<\/span><\/p>\n Feeling sleepy when it gets dark is the most obvious sign of our biological clock at work. A functioning circadian rhythm is also reflected in our shifting energy levels every 20\u201328 hours.\u00a0<\/span><\/p>\n Our internal clock is mainly influenced by daylight and darkness. Other factors like health or substance abuse also play a role.<\/span><\/p>\n You\u2019ll know your internal clock is ticking in a healthy rhythm if you feel energetic, hungry, or sleepy at a specific time of day.<\/span><\/p>\n The connection between the circadian rhythm and daylight isn\u2019t accidental. We become less active when our bodies detect less daylight. In essence, our internal biorhythm is what regulates when we sleep and when we\u2019re awake.<\/span><\/p>\n Now, a <\/span>circadian rhythm disorder <\/span>is essentially any disturbance in our internal clocks. These disorders aren\u2019t uncommon and can manifest as a physical or mental illness or simply as a sleep dysfunction.<\/span><\/p>\n Changes in the circadian rhythm can disrupt our typical sleep-wake cycle and severely affect our life quality.<\/span><\/p>\n This is why NASA has been developing systems that mimic a natural daylight cycle in space to prevent astronauts from losing their internal rhythm, especially during prolonged flights and space stays.<\/span><\/p>\n The bad news is that this disorder leads to insufficient, excessive, or ineffective sleep.<\/span><\/p>\n The good news is that modern medical equipment can record our <\/span>stages of sleep<\/span><\/a> and then identify any unnatural shifts in our sleep patterns to help uncover the source of the problem.<\/span><\/p>\n Several studies<\/span><\/a> show that a broken circadian rhythm can lead to seasonal affective disorders, bipolar disorders, cardiovascular problems, kidney problems, and cancer. Hence, <\/span>delayed sleep phase disorder treatment<\/span> is highly advised.<\/span><\/p>\n Frequent and prolonged shifts in your daily routine, fatigue, and chronic stress all lead to biorhythm problems. This can begin in the form of common sleep disturbances, followed by general anxiety, increased irritability, neurological and psychological problems, and physical concerns.<\/span><\/p>\n Among the possible reasons behind the occurrence of this disorder, two are well established:<\/span><\/p>\n The underlying causes of a circadian rhythm disorder could also be grouped as follows:<\/span><\/p>\n Since our sleep is regulated by homeostasis, short-lived disturbances in the sleep-wake cycle don\u2019t cause any serious problems. This \u201cdelay\u201d is adjusted within just a few hours, and everything returns to normal.<\/span><\/p>\n But if your body\u2019s sleep cycle is upset for an extended period, you may have a sleep disorder.\u00a0<\/span><\/p>\n Let\u2019s take a closer look at some of these.<\/span><\/p>\n This type of sleep disorder is more common in young people and is characterized by delayed sleep until around 2 AM or later. In this case, one might avoid sleep deprivation by sleeping in late.<\/span><\/p>\n However, individuals with <\/span>delayed sleep phase syndrome<\/span> suffer from daytime sleepiness, which impairs their work or school performance. Because of this, patients could be considered lethargic, disinterested, or lazy.<\/span><\/p>\n The truth is that these \u201cnight owls\u201d are productive and creative late at night but chronically tired for any morning duties.<\/span><\/p>\n This condition is the exact opposite of <\/span>delayed sleep phase disorder<\/span>. Some consider it a <\/span>natural process of aging<\/span><\/a>. What is it?<\/span><\/p>\n People with ASPD go to bed earlier than usual (between 6 PM and 9 PM), which leads to waking up early in the morning (between 2 AM and 5 AM). According to numerous studies, <\/span>about 1% of middle-aged and elderly<\/span><\/a> develop this syndrome.<\/span><\/p>\n People with this syndrome are the so-called \u201cmorning larks\u201d and suffer from sleepiness in the late afternoon or early evening and <\/span>insomnia<\/span><\/a> in the early morning.<\/span><\/p>\n Here, the circadian rhythm is so disorganized that there\u2019s no known sleep or wake pattern.\u00a0<\/span><\/p>\n This condition is typical in people with dementia or other neurodegenerative diseases, tumors, and children with intellectual disabilities.<\/span><\/p>\n It\u2019s thought that this irregular sleep-wake disorder occurs when the core of our internal clock (the hypothalamus) degenerates or when it isn\u2019t exposed to adequate day\/night light patterns. The most common <\/span>irregular sleep patterns side effects<\/span> include insomnia, excessive daytime sleepiness, and endocrine disturbances (hormonal disbalance).<\/span><\/p>\n With this disorder, sleep becomes fragmented \u2014 over a 24-hour period, people may take a <\/span>series of naps<\/span><\/a> to get an average amount of sleep. The diagnosis is made when <\/span>at least three sleep-wake episodes<\/span><\/a> last between 1 and 4 hours.<\/span><\/p>\n Sleep time shifts a little bit each day for people with this disorder.<\/span><\/p>\n The N24 sleep disorder usually occurs when there\u2019s no light cue to guide our internal clock \u2014 hence the link between this <\/span>circadian rhythm disorder <\/span>and<\/span> blindness<\/span>. Namely, as much as 70% of blind people are affected by this disorder, although it can also occur in sighted people.<\/span><\/p>\n The side effects of this disorder are insomnia and daytime drowsiness, especially if this continues for several weeks.<\/span><\/p>\n Can you change your circadian rhythm<\/span> at will? Jet lag puts this question to the test. When our internal sleep and wakefulness routine conflicts with the patterns in a new time zone, it results in a temporary sleep disorder called jet lag.<\/span><\/p>\n It\u2019s not unusual for an individual to have difficulties adjusting to a new time zone. The good news is that there are some <\/span>tips on overcoming and avoiding jet lag<\/span><\/a>.<\/span><\/p>\n For instance, when traveling west, you\u2019ll be dealing with <\/span>delayed sleep phase syndrome<\/span>, <\/span>treatment<\/span> for this type of jet lag will resemble said disorder.<\/span><\/p>\n Traveling east is even more complicated than a westward trip because it\u2019s easier to postpone going to sleep than to make yourself sleep earlier.<\/span><\/p>\n Not having a consistent work schedule leads to this reversible <\/span>circadian rhythm sleep disorder<\/span>. It\u2019s fairly common, considering how many people work rotating shifts or work overnight.<\/span><\/p>\n Shift work disorder is characterized by continual and repeated sleep interruptions that result in insomnia or excessive sleepiness. It can also cause the development of more serious psychiatric problems if it persists for extended periods.<\/span><\/p>\nWhat Is a Normal Circadian Rhythm?<\/b><\/h2>\n
