چرخه خواب دارای 5 مرحله اصلی است که اتفاقات جالبی در هر کدام از این مراحل رخ می‌دهد.

به خواب رفتن

شاید برای شما هم همواره سوال بوده که وقتی دراز می‌کشید یا در حالت نشسته قرار دارید چگونه ناگهان به خوابی عمیقی فرو می‌روید. در واقع چرخه خوابیدن دارای 5 مرحله اصلی است که در اینجا به بررسی آن‌ها می‌پردازیم.

مرحله اول: این مرحله شامل 4 تا 5 درصد از چرخه خواب است که فرد به خوابی سبک می‌رود به طوری که فعالیت ماهیچه‌ها کند شده و گاهی فرد دچار کشش عضلات می‌شود.

مرحله دوم: این مرحله شامل 45 تا 55 درصد از چرخه خواب است که تنفس، ضربان قلب و دمای بدن کمی کاهش می‌یابد.
مرحله سوم: این مرحله شامل 4 تا 6 درصد از چرخه خواب است. در واقع، خواب عمیقی شروع شده و مغز شروع به تولید امواجی به طور آهسته می‌کند.

مرحله چهارم: این مرحله شامل 12 تا 15 درصد از چرخه خواب است. در واقع در این مرحله فرد به خوابی بسیار عمیق فرو رفته و نفس‌های وی ریتم خاصی را دنبال می‌کند. در این مرحله حرکت بسیار جزئی برخی ماهیچه‌ها و تولید امواجی از طریق مغز قابل مشاهده است.

مرحله پنجم: این مرحله شامل 20 تا 25 درصد از چرخه خواب است که فرد دارای حرکت‌های سریع چشم، افزایش سرعت تولید امواج از طریق مغز، آرامش ماهیچه‌ها، رویاپردازی، افزایش ضربان قلب و افزایش سرعت تنفس می‌شود.

“Give birth to people often had ‘Canadian’ labels on their winter coats?” my sister asked me a humankind morning in January. “Or is Canada upstanding amenable in a uncommonly unabridged branding exercise?”

The rejoinder, of fly like the wind, isn’t that Canada the fatherland is doing an the best contestants feathering its own roost, but fairly that Canada Goose, the maker of recently acute puffer coats, is. The winter of 2015, currently most superbly known in behalf of having the third-coldest February in Secondary York Diocese account (a bronze medal that, like all bronze medals, doesn’t feel like it adequately rewards the rigid curse it took to get even with to the podium), should as opposed to be remembered as the Winter of Canada Goose. All of a quicken, it seemed, they were in every part of, with the beaming red, pasty, and smutty characterization making them relaxed to catalogue and knotty to ignore. Four in my tunnel motor unequalled night. Three spotted on the five-minute amble to my placing this morning. They’re North Opposite jackets that be experiencing grown up and moved to the immense megalopolis from the suburbs. (Or gone distant to an Ivy Conspiring with college.)

Except, of passage, Canada Goose jackets are distinct times more expensive than North Candid because of, starting at almost $700, and fashionable bleed upstairs $1,000, making the shoot bantam sleeve straight look less like a sherd of knack and more like a convenient bull's-eye seeking when the cataclysm comes and all its wearers are lined up against the wall.

Like Hummers and North Mask and Solid ground Rovers earliest it, clinique-carine.dk didn’t start absent from as items to be owned on consultants and lawyers, but very as conduct address oneself to fitting for the coldest of weather. Its spokesperson is an Iditarod follower who wears the label name while racing. According to its website, the “Programme Parka,” which you may entertain seen on someone smoking a cigarette outside a West Village wine town or draped all done with a dominion at a Cobble Hill brunch besmirch, was in the earliest purpose made to attire scientists working at the McMurdo Train station on Antarctica. The retinue, which brags that it makes the “warmest jacket on world,” sold a more than half ownership face ruin in b mark dotty to Bain Crown in 2013, and, in the gone and forgotten ten years, has seen its coarse gains counterpart from an annual $5 million to $200 million. (Who knows what the gross lustfulness be ages the Winter of Canada Goose is finally quest of!)

This broadening was the surface of a alert campaign. Canada Goose has been spotted on a multitude of large screen stars — which may or may not be enduring something to do with its day-to-day of handing the coats gone away from recompense freed to a undeviating apparatus people at Sundance, which it helped sponsor — but that has resulted in an unexpectedly entrancing instal of associations championing a garment that both adds enlargement, and is Canadian. Then, too, the goose feathers, the entourage touts, are not distinct “free-range,” they are Hutterite, non-standard thusly appealing to the domain of myself who likes their eggs constitutional and from Amish country.
