Why I Can't Go For Night Classes?
Recently I've been sleeping a lot at night, and I've been feeling much better. I feel I can actually breathe, see things clearer, I'm mentally sharper and I feel less lethargic during the day. And no I haven't been on narcotics, but I can quite rightly say I've been feeling high.
If you have been feeling exactly the opposite of what I've described, and you're a night-owl, well here's a newsflash: its gonna get worse.
Here's Susan Scuti of Medicaldaily.com ; "You love to say you're a night owl, yet your body is telling a very different story. Your circadian rhythms, the routine changes in your behavioral, mental and physical functions that occur over the course of a day, are regulated by a tiny area of the brain commonly known as your 'biological clock.' The suprachiasmatic nucleus (SCN ) is shaped like a pine cone, but is about the size of a grain of rice, though it contains about 20,000 neurons.
When light enters your eye, it activates neurons in the retina that convert photons (light particles) to electrical signals. These signals travel along the optic nerve to the SCN which in turn stimulates several brain regions, including the pineal gland. The pineal gland responds by switching off production of the hormone melatonin, and this makes you feel more awake. The SCN also governs your body temperature, hormone secretion, urine production, and changes in blood pressure. After darkness falls, the SCN signals once again and your body's level of melatonin increases, making
you feel drowsy.
This intricate and complex biological system responds daily and automatically to the rhythms of day and night. Like all biologic beings, you respond to your environment. You are a part of the whole. When youimpose an artificial tempo to your day by going to bed too late, there will be real health consequences."
So, here's some of the blessings you may get as reward for pushing your body to the wall.
" A nearly immediate effect of going to bed after midnight is that it throws off your natural circadian rhythms, governed by your SCN, and this may lead to insomnia . As well as having a harder time falling asleep, you will also have trouble staying asleep. "
" Reduced sleep is also related to an increase in both cardiovascular events and cardiovascular disease. In the Nurses' Health Study, researchers found evidence of increased risk of coronary events in female subjects who obtained seven hours or less of sleep per night compared to those who averaged eight hours per night."
"In a prospective study of 23,995 Japanese women, shorter sleep duration, specifically six hours or less per night, was associated with a higher risk of breast cancer when compared with women who slept seven hours per night. Researchers suggested that melatonin, which is secreted mainly from the pineal gland, is the key factor in this link
between sleep and cancer. Shorter sleep results in a shorter duration of nocturnal melatonin secretion and lower melatonin levels have been associated with an increased risk of breast cancer."
"Increasingly, scientists hypothesize that sleep deficits cause obesity. According to the authors of a study of 1,024 volunteers from the Wisconsin Sleep Cohort Study — a
population-based longitudinal study of sleep disorders — too little sleep apparently alters your body's regulation of appetite-regulating hormones."
"The impact of too little sleep on the immune system has not received very much attention even though sleep deprivation has been shown to activate defense mechanisms and
to elevate certain inflammatory cytokines or cell "messengers" (IL-6, TNF) in young adults. "
