QUES ANSWER MEDICAL 07-2022-08
Dear friends, These are information compiled as QA by me in1998’s-2014’s and stored in my computer. They are posted by very learnt doctors in kidshealth.org etc. Manyimprovements have come in medical field. Hence some information may have additions or some times changes. These are for general information, and for any health problem one has to consult doctor. BEING COMPILATION THERE MAYBE ERRORS. Sincerely, R. Gopalakrishnan, 78, dated 12-07-2022 Q1Now diet soda has come in the market. Is it advisable to drink it? A1 No. That is because a soda habitincreases the risk of developing a condition called metabolic syndrome,according to the new research, andthat in turn boosts the chance of getting both heart disease and diabetes. "Evenone soda per day increases your risk of developing metabolic syndrome by about 50 percent," saysRamachandran Vasan, MD, professor ofmedicine at Boston University School of Medicine and the senior author of the study, publishedin the July 31 issue of Q2 When do dreams occur? A2 Dreaming occurs in thefifthstage of sleep. During sleep, the person occasionallyrolls over or rearranges his or her body This happensapproximately once or twice an hour. This may be the body's way of making sure that no part of the bodyor skin has its circulation cut off for too long a period of time. asleeping person is unconscious to most things happening in the environment. Q3 What is the differencebetween deep sleep and fainting AND COMA? A3 The biggest differencebetween someone who is asleep and someone who has fainted or gone into a comais the fact that a sleeping person can be aroused if the stimulus is strongenough. If you shake theperson, yell loudly or flash a bright light, a sleeping person will wake up. Q4 Do all creatures dream?What about the sleep pattern of different animals? A4 By studyingbrainwaves, itis known that reptiles do not dream. Birds dream a little. Mammals all dream during sleep. Different animals sleepin different ways. Some animals, like humans, preferto sleep in one long session. Other animals (dogs, forexample) like to sleep in many short bursts. Some sleep atnight, while others sleep during the day. Cows can sleep whilestanding up, but they only dream if they lie down. Whales anddolphins are "conscious breathers," and they need to keep breathingwhile they sleep, so only one half of the brain sleeps at a time Q5 What are alphabeta, teta and delta waves? A5 If you attachan electroen- cephalograph to a person's head, you can record the person'sbrainwave activity. An awake and relaxed person generates alpha waves,which are consistent oscillations at about 10 cycles per second. An alert persongenerates beta waves, which are about twice as fast. During sleep, two slowerpatterns called theta waves and delta waves take over. Theta waves haveoscillations in the range of 3.5 to 7 cycles per second, and delta waves haveoscillations of less than 3.5 cycles per second. As a person falls asleepand sleep deepens, the brainwave patterns slow down. The slower the brainwavepatterns, the deeper the sleep -- a person deep indelta wave sleep is hardest to wake up. Q6 What is REM sleep? A6 At several points during the night,something unexpected happens - rapid eye movement (REM) sleep occurs. Mostpeople experience three to five intervals of REM sleep per night, andbrainwaves during this period speed up to awake levels. If you ever watch aperson or a dog experiencing REM sleep, you will see their eyesflickering back and forth rapidly. In many dogs and somepeople, arms, legs and facial muscles will twitch during REM sleep. Periodsof sleep other than REM sleep are know as NREM (non-REM) sleep. REM sleep is when you dream.If you wake up a person during REM sleep, the person can vividly recall dreams.Ifyou wake up a person during NREM sleep, generally the person will not bedreaming. You must have both REMand NREM sleep to get a good night's sleep. A normal person willspend about 25 percent of the night in REM sleep, and the rest in NREM.A REM session -- a dream -- lasts five to 30 minutes. Q7Do missing sleep is fatal? A7Missing one night of sleep is not fatal. A person will generally beirritable during the next day and will either slow down (become tired easily)or will be totally wired because of adrenalin. If a person misses two nights of sleep, it gets worse. Concentrationis difficult, and attention span falls by the wayside. Mistakes increase. After three days, a personwill start to hallucinate and clear thinking is impossible. With continuedwakefulness a person can lose grasp of reality Q8 Do growth harmonsecreated during sleep? A8 Yes.Growth hormone in children is secreted during sleep, and chemicals important tothe immune systemare secreted during sleep. You can become moreprone to disease if you don't get enough sleep, and a child'sgrowth can be stunted by sleep deprivation. Q9Do Sleep lowers our energy consumption? A9 Yes. Sleep lowers our energy consumption, so we need three meals a dayrather than four or five. Since we can't doanything in the dark anyway, we might as well "turn off" and save theenergy. My note- Diabetics may often require someeatables handy in the night, preferably sweet items like plantain. Q10Why do we require sleep? A10According to ScienceNewsOnline:Napless cats awaken interest in adenosine, sleepmay be a way of recharging the brain, using adenosine as asignal that the brain needs to rest: "Since adenosine secretion reflectsbrain cell activity, rising concentrations of this chemical may be how theorgan gauges that it has been burning up its energy reserves and needs to shutdown for a while." Adenosine levels in the brainrise during wakefulness and decline during sleep. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
