I m a student but can not remember which I read. So what I should do for this please help.

Psychologist, Chennai
Walk before an exam. Teach what you have learned to someone else. Take regular study breaks after 40-45 mins. Music can also help elevate your mood and motivate to study longer. Make your study space portable. Practice. Practice. Practicing simple answers to past exam questions can help train your brain to retrieve information. Do not stay up all night before exams. Discover new ways to learn. Study in a group- helps to collect new insights & enhances your learning experience. Sq3r strategy to help you concentrate, understand and remember what you are studying. S- survey (look at headings and key points) q- question (what do I already know? what do I want to know?) r-read (read the text) r-recite (try to remember what you have read) r-review (the work you have learned)

How can we control stress
And in what way we can control and please reply to my questions.
If the work load is causing the stress, learn to manage your work well. You could talk to your supervisor and tell him about the stress and he may suggest some better ways of doing what you are doing. Stress is eventually all about the perception of stress. If you change the outlook, the result will be 350`different. If there is a possibility to delegate some work to someone else, please do so. To feel energized you must eat healthy food involving whole grains, fruits and vegetables. Drink green tea and a lot of buttermilk every day. You may eat an egg every day too: it is a multivitamin and multi-mineral, all built into one. You must exercise regularly, especially the aerobic kind. Get at least 8 hours of good sleep and the more you sleep before midnight the better. Learn some stress management and meditation. You must identify our feelings and make sure you express all of them, appropriately. Maintain good relations, especially at home. Deep breathing exercises help to calm a person, immediately. Do not indulge in drinking and smoking.

Advice. Avoid sitting cross legged. Avoid squatting- quadriceps exercises- lie straight, make a towel role and put it under the knee, press the keen against the role, hold it for 20 secs. Repeat 20 times twice a day. This will help relieve some pain. Core strengthening exercise- straight leg raised with toes turned outward, repeat 10 times, twice a day. Hams stretching- lie straight, take the leg up, pull the feet towards yourself, with a elastic tube or normal belt. Repeat 10 times, twice a day. Sports taping- stretch the tape from both ends and apply on the affected area contrast fomentation (hot and cold).

You are studying for too long and this will lead to mental fatigue and you will suffer a lot of memory loss. Yes, Yoga will help with stress management and memory retention. You may also follow the recommendations given below which does include Yoga: Daily exercise of at least half an hour is a must. Even if you go to a gym, ask for aerobic and/or callisthenic exercises with whatever else you are doing. A healthy body harbors a healthy mind. With regard to memory, it is very important that your brain and body is ideally rested to be able to recall whatever is required, rather comfortably. Puzzles pose problems to the brain that help it to use new pathways and neurons, which give the brain considerable exercise. It taxes the left brain to use logic to solve the myriad possibilities which other activities do not stimulate. Crosswords are excellent for vocabulary learning and use. Jigsaws and Rubik cube stimulate different permutations to finally settle on the most likely one. Picture completion and anagrams help approach problem-solving from several angles. Do Sudoku, and memory co-relation activities and skills. Have a good night’s sleep, have a good breakfast of more proteins, meditate often, remain free of stress, eat a lot of fiber (whole grains, fruits and vegetables), nuts, avocado, eat dark chocolate, consume less of fat and use olive oil instead, do Yoga meditation exercises, etc. You need to check out if you are stronger visual or auditory. The visual is a better mode than the auditory. However, if you combine the two modes, you will get the best concentration. Have a special place of learning, which should be well lit, with soft painted walls, well-ventilated, with no distractions. When you get bored, study by writing. If you repeat learning, at least, five to seven times, you will apparently remember for a longer time. Sit comfortably but do not slouch. The reading material should be of a fairly large print. Study at small intervals of about 40 minutes and then take a break or change the subject. Short-term memory is a faculty of the left brain, and long-term memory is a feature of the right brain. When people are stressed, they tend to favor the right brain and abandon the left brain, where short-term memory resides. So, it is really very simple: deal with the stress and activate left brain functions. Here are a few suggestions to activate left brain function: shut your left nostril and breathe, move your eyes from right to left and vice versa for at least half a minute at a time, and do callisthenic exercises with some form of counting, regularly. There is a new exercise called Super Brain Yoga, which is done by holding the right earlobe with your left thumb and index finger, and the left earlobe with your right hand’s thumb and index finger. In this position, you must squat down and rise up and do this for five minutes every day. There is some memory enhancing techniques and study methods that your teacher will be able to guide you with. If your home life is full of distractions and stress, it is likely to affect your memory, adversely. The following foods do help too: Blueberries, walnuts, turmeric, Spinach, tomatoes, broccoli, acorn squash, green tea, oily fish, boiled egg, turkey, apples, oatmeal, leafy greens, lentils, pumpkin seeds, avocado, cinnamon, thyme, sunflower seeds, and red wine. Avoid sugar and junk food.

You need to get help from a psychologist. You should realize that the origin point of anxiety and depression is in your head and the end will also be the same. Find someone who can help you put spotlight on the faulty thought pattern and one's life philosophy. Anxiety is always futuristic and a result of obsession with the outcome and fear of negative happening. It is an imagined negative future happening, whereas one does not realize that anticipated unpleasant-happening may or may not occur but one keeps burning in present to avoid & by fearing it!

Most Practical Ways of Controlling Everyday STRESS

Most Practical Ways of Controlling Everyday STRESS

We generally use the word 'stress' when we feel that everything becomes too much to handle - we are overloaded and wonder whether we can cope with the pressures placed upon us. Nowadays stress is a normal part of life. Almost everyone has some sort of stress. Constantly reacting to stressful situations without making adjustments to counter the effects, threatens our health and well-being.

There are steps you can help you managing day to day stressful conditions and take to feel better.

  1. Be realistic: If you feel overwhelmed by some activities (yours and/or your family's), learn to say NO! Eliminate an activity that is not absolutely necessary. You may be taking on more responsibility than you can or should handle. If you meet resistance, give reasons why you're making the changes. Be willing to listen to other's suggestions and be ready to compromise.
  2. Shed the 'superman/superwoman' urge: No one is perfect, so don't expect perfection from yourself or others. Ask yourself, 'What really needs to be done?' How much can I do? Is the deadline realistic? What adjustments can I make?' Don't hesitate to ask for help if you need it.
  3. Take one thing at a time: For people under tension or stress, their day-to-day workload can sometimes seem unbearable. The best way to cope with this feeling of being overwhelmed is to take one task at a time. Make a list of things you need to get done and start with one task. Once you accomplish that task, choose the next one. The positive feeling of 'checking off' tasks is very satisfying. It will motivate you to keep going.
  4. Share your feelings: A conversation with a friend lets you know that you are not the only one having a bad day. Stay in touch with friends and family. Ask them how they have dealt with a similar situation that may be 'stressing you out.' Let them provide love, support and guidance. Don't try to cope alone.
  5. Be flexible: If you find you're meeting constant opposition in either your personal or professional life, rethink your position or strategy. Arguing only intensifies stressful feelings. Make allowances for other's opinions and be prepared to compromise. If you are willing to be accommodating, others may meet you halfway. Not only will you reduce your stress, you may find better solutions to your problems. Go easy with criticism. You may expect too much of yourself and others. Try not to feel frustrated, disappointed or even 'trapped' when another person criticises you.
  6. Hobbies: Take a break from your worries by doing something you enjoy. Whether it's gardening or painting, schedule time to indulge your interest. Exercise: Regular exercise is a popular way to relieve stress. Twenty to thirty minutes of physical activity benefits both the body and the mind. Meditate: Just ten to twenty minutes of quiet reflection may bring relief from chronic stress as well as increase your tolerance to it.
  7. Take Herbal Supplement: Herbs like Brahmi, Ashwagandha, Mandukparni, Shankhpuspi, Kaunch are very helpful in managing stress. These herbs work on the brain and help relax you which ultimately empowers you to manage your stressful conditions easily. There are many herbal supplements available in the market that can help you.
  8. Consult the Doctor: If your stress level doesn't seem to improve with above tips, it may require more attention and consultation with an Expert.

Hi lybrate-user, I have been through this during my own training. First you need to go back to the purpose of why you want to become a doctor. Then trace it forward by deciding what you can do immediately. Make daily target, simple ones which you can achieve. Don't take load which you can't handle. To start with, what are you going to do tomorrow? Write it down on a piece of paper and see how much you did. You are going through this so that one day you can understand the pain of others. So you are on the path of becoming a sensitive doctor. Best of luck!

How much is too much. I am under severe depression. My husband is obsessed with sex. We have sex daily. Which is still not enough for him. If I refuse to have sex with him on a day he has problems coping and understanding. He will sulk to the extent as if something very very wrong has been denied to him. having sex with him daily is a task. If I do not respond while having sex he will be so disappointed. All day he talks about sex. Pls help me understand that what are a normal physiological needs of sex for a man. I have sex daily and many times 2 times in a day. Is this normal?

I feel the issue here is lack of open interaction and communication between you and your husband. Basically marriages in our country are usually solemnized with very very little understanding regarding marriage and sexuality. Everything here is on experiment. Even pregnancy and childbirth. This clearly conveys that marriage and relationship is a lottery. Solution to this issue is very simple premarital guidance. But usually ignored at the time of marriage by couple and elders with the hope that everything will be alright. My opinion is that if quality premarital/marital guidance with an expert sexologist/relationship coach becomes a routine. Quality of life and contentment level in married couples will grow many folds. As an expert I am dealing with such cases routinely. I suggest you to talk to your husband and tell him that you also like quality sex and for that you would like to meet an expert and learn basics from expert so that you can increase pleasure in sexual relations for him and also ask him to accompany you. When he finds his benefit, he will agree for the guidance session and that's your way out from this unhappy one-sided sex. This will also let you know many myths and facts and you will be wiser and happy. But be tactful and diplomatic in talking to your husband and avoid finding faults with him even in front of expert. You may tell your problems separately to the expert. Move on, all the best.

What can I do my husband is get doubt for me. He says my affair with other man but its not true. Please advise.

Hypnotherapist, DCS, BSIC, Advanced Trainee of Transactional Analysis, Advanced Skills in Counselling
There could be many reasons for him to doubt you. He might be prone to doubting people generally. Or he wants you to be within his control and this would be a good way to do that. Or some person has said something to him and he believes it. Whatever the reasons are, it would be impacting your married life as well as peace of mind. It would be important to go for marital counselling to clear out the air between the two of you. Sometimes other issues are also linked to doubting behaviour, like poor self esteem, feeling uncared for, suspicious nature etc. Counselling will help you both to voice such other aspects of hidden nature and improve the quality of communication between you two.

General Physician,
Only by using strong will power and avoiding all situations where you feel like smoking, chewing tobacco or drinking or using drugs/ weed, avoiding friends who smoke and diverting mind by reading or chewing a gum, like NICORETTE and taking a walk when you crave for a smoke can all help. You can chew Nicorette gum which is nicotine replacement. There are medicines available. Which can be prescribed if asked personally Cigarette smoking is a leading preventable cause of mortality. It kills more than 60 lakh people worldwide every year. More than 50% of regular smokers would invariably die from tobacco-related illnesses which includes heart attack, cancer or asthmatic lung diseases. Best age to stop smoking is before 40 31st May is “World No Tobacco Day” Quitting smoking before the age of 40 is associated with larger decline in premature death than stopping it at a later date. Best age therefore to stop smoking is before 40. However, stopping smoking even after the age of 50 is still associated with lower risk of death as compared to those who continue to smoke. Even in smokers aged 80 years or more, quitting smoking appears to reduce some mortality.

Dear lybrate-user, at your age, memory problems like amnesia, dementia or alzheimer's are not common. Many young people do complain having problems with memory. These problems are due to either they are too busy or due to anxiety and stress. Busy people use organizers or employ a personal assistant because they can't remember every task. You need to understand this. If you still say, you are having memory problems, we need to check your memory using memory test. You may contact a clinical psychologist or neurologist for memory test and further investigation. Take care.

Hi I am 27 yrs male. My problem is I get excessive sweat mainly when ever I get tensed, fear, anxious or nervousness ...
These are anxiety attacks by your over-reaction to fearful situations, especially when you have to face an interview. You are having a problem handling fear and this may be habituated from childhood from overbearing parents. Either one or both of your parents may have exercised strict controls and expectations on you and now you have become intimidated by this pressure. They may have meant well but could have in the bargain gone overboard and caused this reaction in you. You should meet with a counselor and learn how to handle this fear and master your emotions. This is not to control your feelings but to learn to express them appropriately. When we are afraid it is very important to express the feeling but also to reach out for support. You may also go for public speaking skills course or attend the ?Toastmasters Club?. Additionally, you may attend a personality development course. Visit a gym and build your body image, do aerobic exercises, Yoga and meditation, eat healthily, and sleep well. Handling emotions efficiently will go a long way to make you face your fear. You may also take some multivitamins and multi-minerals as supplements.
