Science has linked poor slumber with a number of health problems , from weight gain to a weakened immune system.
Read on to learn the causes of sleep deprivation and exactly how it affects specific body functions and systems.
In a nutshell, sleep deprivation is caused by consistent lack of sleep or reduced quality of sleep. Getting less than 7 hours of sleep on a regular basis can eventually lead to health consequences that affect your entire body. This may also be caused by an underlying sleep disorder. Your body needs sleep , just as it needs air and food to function at its best. During sleep, your body heals itself and restores its chemical balance.
Your brain forges new thought connections and helps memory retention. It can also dramatically lower your quality of life. A review of studies in found that sleeping too little at night increases the risk of early death.
In fact, these can make sleep deprivation worse by making it harder to fall asleep at night. This, in turn, may lead to a cycle of nighttime insomnia followed by daytime caffeine consumption to combat the tiredness caused by the lost hours of shut-eye. Your central nervous system is the main information highway of your body. Sleep is necessary to keep it functioning properly, but chronic insomnia can disrupt how your body usually sends and processes information.
You may also find it more difficult to concentrate or learn new things. The signals your body sends may also be delayed, decreasing your coordination and increasing your risk for accidents. Sleep deprivation also negatively affects your mental abilities and emotional state. You may feel more impatient or prone to mood swings. It can also compromise decision-making processes and creativity. A lack of sleep can also trigger mania in people who have bipolar mood disorder. Other psychological risks include:.
You may also end up experiencing microsleep during the day. It can also make you more prone to injury if you operate heavy machinery at work and have a microsleep episode. While you sleep, your immune system produces protective, infection-fighting substances like antibodies and cytokines. It uses these substances to combat foreign invaders such as bacteria and viruses. Certain cytokines also help you to sleep, giving your immune system more efficiency to defend your body against illness.
Sleep deprivation prevents your immune system from building up its forces. Long-term sleep deprivation also increases your risk for chronic conditions, such as diabetes mellitus and heart disease. The relationship between sleep and the respiratory system goes both ways. A nighttime breathing disorder called obstructive sleep apnea OSA can interrupt your sleep and lower sleep quality. Both his enlistment in the army and his subsequent volunteering for front line duty were automatic responses to emotional rebuffs.
Strange, because it was composed on December 24, , and the whole of the second week of that month had been spent by Guillaume and Lou in the most deliriously prolong bout of love-making that the poet was ever to enjoy. Perhaps for the first time in his life he had reasons to keep a love affair secret. His letters to Lou have never been published, and only a selection of the poems has so far been made available. As so often, it was a crisis that impelled Apollinaire into his new phase of poetic invention.
He had met Loud in Nice, where he had gone after the outbreak of war, at an opium-smoking party, and had courted her tirelessly but fruitlessly for the three following months. Frustrated and wounded by successive rebuffs, he had enlisted and then sent her an artfully worded protestation of undying love. When she returned, satiated, to Nice a week later, her thoughts immediately began to turn elsewhere; but Guillaume, of course, was no more capable now than he ever had been of conceiving that a woman might no longer desire him.
This frenetic correspondence produced an inspired flow of powerfully sensual poetry which was the most direct and genuinely felt lyrical expression that he ever achieved: the clear flame of erotic passion illuminated aspects of his nature that he had concealed hitherto under a cloak of gentle melancholy. It seemed that nothing would quench this flame. Even when she had made it abundantly clear in her answering letters that their sexual adventure was over, he continued his dithyrambics.
Lou unwittingly enmeshed him in an even more unlikely and pathetic adventure. After an overnight assignation with her in a Nice hotel during January , Apollinaire had got into conversation with a young girl in the train that took him to Marseille on the first stage of his journey back to his unit. They had discussed poetry and exchanged addresses before saying goodbye. On April 16, remember the stranger in the train, he wrote her a polite postcard, offering to send her a copy of Alcools.
A box of cigars soon arrived as a present from her and a very peculiar correspondence indeed was under way. His letters to her which we only know in expurgated form became increasingly amorous as he gradually gained the confidence of this shy, sensitive young schoolteacher living with mother and younger brothers and sisters in the suburbs of Oran, Algeria.
At the beginning, in a display of duplicity, which brings back memories of the old gay Gui, he continued to write in loving terms to Lou, and on more than one occasion he sent identical poems to both Lou and Madeleine.
Only three months after their first exchange of letter he was actually proposing marriage to Madeleine. Completely captivated by now, she accepted, her mother gave her approval, and they were officially engaged! It now seemed perfectly normal to Apollinaire that, being engaged, he should be free to write to her in overtly erotic terms.
The rest of the romance of Gui and Madeleine is a tragicomedy. A Christmas leave with Madeleine and her family in Oran appears to have been a failure; probably the lubricious fantasies of this improbably courtship were doomed to evaporate in the cold light of physical reality.
Nothing was to be the same again. Apollinaire lives for another two years and eight months, dying forty-eight hours before the armistice, of Spanish flu aggravated by a recent bout of pneumonia and the lingering after-effects of his head wound.
An illusion, like love. It was the poetry that was real, in all its novelty, astonishment and complication. Can you spell these 10 commonly misspelled words? Love words? Need even more definitions?
