What Is A Chronotype?
Research shows that your bedtime may actually be linked to your DNA! Everyone’s biological clock is wired differently; it’s not in sync. Environmental and genetic factors affect your circadian rhythm, or your internal clock. Circadian rhythms, in turn, influence your sleeping pattern.
Your preferred sleeping pattern is called your ‘chronotype.’ Going to sleep around 11 PM and waking up around 7 AM puts you in the average chronotype category. Someone with an average chronotype gets roughly the same amount of sleep on both working and non-working days, and this is good.
About 40% of the population does not belong to this category. They have late or early chronotypes. These people will find it pretty difficult to go to work after a free day. They may even experience symptoms of jet lag.
What contributes to the difference in chronotypes?
Melatonin: The Sleep Hormone
Melatonin is the “sleep hormone” that regulates the sleep-wake cycle in the body. It is produced by a neuron bundle called Suprachiasmatic Nucleus or SCN for short.
For people with the average chronotype, melatonin production starts around 9 PM, and the whole body enters into the ‘rest mode’ by 10:30 PM. The body temperature enters its lowest around 4:30 AM. These people usually wake up around 6:45 AM when the blood pressure spikes to the highest point. They are known as the ‘early risers’ and are alert and active during the daytime.
For people with the late chronotype, this whole cycle happens later during the day. As a result, they tend to sleep and wake up much later.
They may not entirely be able to fix this. This is because the CLOCK genes found in the SCN neuron bundle regulate the 24-hour cycle in your body. Changes in the CLOCK genes influence your chronotype status – average, or early, or late.
A study was carried out on hamsters to study the contributing factors to chronotype. Scientists replaced the SCN of early chronotype hamsters with that of average chronotype hamsters. To their surprise, the hamsters still went to sleep and woke up early, according to their early chronotype.
This is because, other than the SCN clock, the body also contains other biological clocks, all of which contribute to a person’s chronotype. And, this is why it can be very difficult to break out of your natural sleeping pattern.
Chronotype Genetic Test
To know what your chronotype is based on your genes, you can get a genetic test done. Most genetic tests provide your DNA information in the form of a text file called the raw DNA data. At Xcode Life, can help you interpret this data.
All you have to do is upload your raw data and order a sleep report. Xcode Life then analyzes your raw data in detail to provide you with a comprehensive sleep analysis, including information on your chronotype and risk for various sleep disorders.
Chronotype Ni Nini? Utafiti unaonyesha kwamba huenda wakati wa kulala ukahusiana na DNA yako! Saa ya kibiolojia ya kila mtu imepangwa kwa njia tofauti; haifanyi kazi kwa upatano. Vipengele vya mazingira na vinasaba vinaathiri mzunguko wa mwili wa binadamu. Mzunguko wa mzunguko wa saa huathiri jinsi unavyolala. "Mfano wa kulala unaopendelea unaitwa ""chronotype"" yako: kulala karibu saa 11 jioni na kuamka karibu saa 7 asubuhi inakuweka katika jamii ya kawaida ya chronotype." Kwa mfano, mtu mwenye chronotype ya kawaida hupata usingizi sawa siku zote mbili za kazi na siku zisizo za kazi, na hii ni nzuri. Karibu asilimia 40 ya watu hawafai katika jamii hii. Wana chronotypes ya marehemu au ya mapema. Watu hawa watapata ugumu wa kwenda kazini baada ya siku ya kupumzika. Huenda hata wakaona dalili za kutoelewana na ndege. Ni nini kinachosababisha tofauti hiyo ya aina za wakati? Melatonini: Homoni ya usingizi Melatonini ni "homoni ya usingizi" ambayo husimamia mzunguko wa usingizi-kuamka mwilini. Ni inayotokana na neuroni bundle aitwaye Suprachiasmatic Nucleus au SCN kwa kifupi. Kwa watu wenye chronotype ya kawaida, uzalishaji wa melatonin huanza karibu saa 9 jioni, na mwili wote huingia katika "hali ya kupumzika" karibu saa 10:30 jioni. Joto la mwili huingia kiwango cha chini zaidi karibu saa 4:30 asubuhi. Watu hawa huamka karibu saa 6:45 asubuhi wakati shinikizo la damu linapopanda hadi kiwango cha juu. Wanajulikana kama "waamkaji wa mapema" na ni macho na wenye shughuli nyingi wakati wa mchana. Kwa watu wenye chronotype ya marehemu, mzunguko huu wote hutokea baadaye wakati wa siku. Kwa sababu hiyo, wao hulala na kuamka baadaye sana. Huenda wasiweze kurekebisha jambo hilo kabisa. "Kama vile kuna ""Clockwork"" gene katika mfumo wa neuroni ya SCN, ambayo huongoza mzunguko wa saa 24 katika mwili." Mabadiliko katika jeni la saa huathiri hali yako ya chronotype <unk> wastani, au mapema, au marehemu. Utafiti ulifanywa juu ya hamsters kujifunza mambo yanayochangia chronotype. Wanasayansi walibadilisha SCN ya hamsters za chronotype za mapema na ile ya hamsters za chronotype za wastani. Kwa mshangao wao, hamsters bado walilala na kuamka mapema, kulingana na chronotype yao ya mapema. Hii ni kwa sababu, mbali na saa ya SCN, mwili pia una saa nyingine za kibiolojia, ambazo zote zinachangia chronotype ya mtu. Hii ni kwa nini inaweza kuwa vigumu sana kuvunja nje ya muundo wako wa kawaida wa kulala. Chronotype Genetic Test: Kwa nini chronotype yako haijulikani? Uchunguzi wa maumbile ya maumbile huonyesha DNA yako katika faili ya maandishi inayoitwa data ya DNA. Xcode Life inasaidia katika kuhariri data hii. Unachohitaji kufanya ni kupakia data yako mbichi na kuagiza ripoti ya usingizi. Xcode Life kisha inachambua data yako mbichi kwa undani ili kukupa uchambuzi wa usingizi wa kina, pamoja na habari juu ya chronotype yako na hatari ya matatizo mbalimbali ya usingizi.
