QUES ANSW MEDICAL 07-2022-04 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 04-07-2022 Q1 Do age tell upon sleep? A1 Yes.About half of all people over 65 have frequent sleeping problems, such asinsomnia, and deep sleep stages in many elderly people often become very shortor stop completely. This change may be anormal part of aging, or it may result from medical problems that are common inelderly people and from the medications andother treatments for those problems. My note- I haveobserved certain medicines increaseblood sugar, create constipation and insomania Q2 Why should we sleep? Is it necessary? A2 Although scientists are still tryingto learn exactly why people need sleep, animal studies show that sleep is necessary for survival. Q3 What is Circadian rhythms and its effect on biologicalclock ? A3 Circadian rhythms are regular changes in mental and physicalcharacteristics that occur in the course of a day (circadian is Latin for "around a day"). Mostcircadian rhythms are controlled by the body's biological "clock." This clock,called the suprachiasmatic nucleus or SCN, is actually a pair of pinhead-sizedbrain structures that together contain about 20,000 neurons. The SCN restsin a part of the brain called the hypothalamus, just above thepoint where the optic nerves cross. Light that reaches photoreceptors in theretina (a tissue at the back of the eye) creates signals that travel along theoptic nerve to the SCN. Signals fromthe SCN travel to several brain regions, includingthe pineal gland, which responds to light-induced signals by switching offproduction of the hormone melatonin. The body's level of melatonin normally increasesafter darkness falls, making people feel drowsy. Q3 Do biological clock work on 25 hour cycle? A3 By depriving people of light and otherexternal time cues, scientists have learned that most people's biologicalclocks work on a 25-hour cycle rather than a 24-hour one. Q4 What is jet log? A4 Whentravelers pass from one time zone to another, they suffer from disruptedcircadian rhythms, an uncomfortable feeling known as jet lag. For instance, if you travel from California to New York, you "lose" 3hours according to your body's clock. Youwill feel tired when the alarm rings at 8 a.m. the next morning because,according to your body's clock, it is still 5 a.m It usuallytakes several days for your body's cycles to adjust to the new time. My note- Itis understood, if a person frequently travel between placed with differenttimezones, jetlag is not much felt. Readers can comment on their experience. Q5 How to reduce jet logeffect? A5 To reducethe effects of jet lag, some doctors try to manipulate the biologicalclock with a technique called light therapy. They exposepeople to special lights, many times brighter than ordinary household light,for several hours near the time the subjects want to wake up.This helps them reset their biological clocks and adjust to a new time zone. Q6Do similar symptoms like jet log happen to workers on shift duty? A6 Symptomsmuch like jet lag are common in people who work nights or who perform shiftwork. Because thesepeople's work schedules are at odds with powerful sleep-regulating cues likesunlight, they often become uncontrollably drowsy during work, andthey may suffer insomnia or other problems when they try to sleep. Shift workers have an increased risk of heartproblems, digestive disturbances, and emotional and mental problems, all ofwhich may be related to their sleeping problems. Thenumber and severity of workplace accidents also tend to increase during thenight shift Q7 What is Sleep until sunlight? A7 If possible, wakeup with the sun, or use very bright lights in themorning. Sunlight helpsthe body's internal biological clock reset itself each day. Sleep experts recommend exposure to an hour of morning sunlight forpeople having problems falling asleep. Q8 Do blinking is good for the eye? A8 Consciously remind yourself to blink every 3-5 seconds. Ofcourse, you don't want to go through the day with a stopwatch, but the more conscious youare of blinking regularly, the better it is for your eyes. The eyelid is the only part ofthe body that is controlled by just one muscle. Any other movement usuallyinvolves 2 muscles – one that contracts and one that stretches to make themovement. Your eyelid is controlled byonly one muscle. By having proper relaxation in that muscle, it can promoterelaxation throughout the entire body. That's why you often hear hypnotists using the phrase"your eyes are becoming heavy" as a way to get their subject tobecome more relaxed. A blinking exercise that you canpractice frequently throughout the day is called Flutter Blinking. To practice Flutter Blinking,blink your eyes lightly and rapidly 10 to 20 times. Do not strain or squeezeyour eyes shut and relax your face as you blink. Then close your eyes andrelax. Repeat this 2 or 3 times. Flutter Blinking will help to keep your eyes moist,relaxed and free of strain. Q9 What'sa Phobia? A9 phobia (say: fo-bee-uh) is the fancy name for a fear. But a phobia isn't just any kindof fear. It's normal for kids to be afraid of things — like taking a hard testat school, passing a growling dog on the street, or hearing a huge clap ofthunder. A kid who has a phobia will beafraid of something every time he or she sees or experiences it. She won't justbe afraid once or twice. Kids who have phobias often go out of their way toavoid the situation or thing that scares them. My note- Phobia with a person doesnotdisappear. It continues till their end Q10 Whydo digestive and urinary system slow done whenyou are in anxiety? A10 And your digestive and urinary systems slow down forthe moment so you can concentrate on more important things. My note- Both I have experienced. If busy with aninteresting work, hunger as well as thinking for going totoilet doesnot appear for hours. But if I am idle I would have eaten small snackitems and gone to toilet at least three times in a period of three hours. Q11 Dothe ear help to hear only? A11 The ear not only helps us hear,but also keeps us steady on our feet. Kids need to hear well to developand use their speech, social, and listening skills. Even mild or partialhearing loss can affect their ability to speak and understand language, whileproblems with balance can influence how they're able to move and how well theyfeel. Q12 Howdo we hear? A12 Hearing begins when sound waves that travel through theair reach the outer ear, or pinna (the visible part of the ear). The outer ear captures the sound vibration and sendsit through the ear canal to the middle ear, which contains the eardrum (a thin layer of tissue) andthree tiny bones (called ossicles). The sound causes the eardrum to vibrate.The ossicles amplify these vibrations and carry them to the inner ear. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
