如何平衡学业和锻炼以保持健康英语作文How to Balance Academics and Exercise to Maintain a Healthy LifestyleIn today's fast-paced world, it can be challenging to find the right balance between academics and exercise to maintain a healthy lifestyle. However, with some planning and dedication, it is possible to achieve this balance and reap the many benefits that come with it. In this article, we will explore some tips on how to balance academics and exercise to ensure your overallwell-being.1. Make a ScheduleOne of the most important aspects of balancing academics and exercise is creating a schedule that allows time for both. Start by identifying your academic commitments such as classes, study sessions, and assignments. Once you have a clear picture of your academic responsibilities, you can then allocate time for exercise. This could be in the form of daily workouts, sports activities, or simply going for a walk or run. By creating a schedule that includes both academics and exercise, you can ensure that you are dedicating enough time to each while avoiding burnout.2. Be RealisticIt's essential to be realistic about the time you can commit to exercise while juggling academic responsibilities. While it may be tempting to push yourself to do more, it's crucial to listen to your body and not overexert yourself. Set realistic goals for your exercise routine and gradually increase the intensity or duration as your schedule allows. Remember, consistency is key when it comes to maintaining a healthy lifestyle, so it's better to do a little bit of exercise regularly than to go all out once in a while.3. Prioritize Self-CareTaking care of yourself is essential to maintaining a healthy lifestyle, so don't neglect self-care practices such as getting enough sleep, eating a balanced diet, and managing stress. All of these factors can impact your academic performance and exercise routine, so prioritize self-care to ensure you are in the best shape physically and mentally. This may include setting aside time for relaxation exercises, meditation, or hobbies that help you unwind and recharge.4. Incorporate Exercise into Your Daily RoutineIf finding time for dedicated exercise sessions is challenging, try incorporating physical activity into your daily routine. Thiscould be as simple as taking the stairs instead of the elevator, walking or biking to class, or doing quick exercises during study breaks. By making exercise a part of your daily routine, you can stay active without having to carve out specific time for workouts.5. Stay FlexibleLife can be unpredictable, and there may be days when it's challenging to stick to your exercise or study schedule. It's important to stay flexible and adapt to changing circumstances while maintaining a healthy balance between academics and exercise. If you miss a workout or study session, don't be too hard on yourself. Instead, focus on getting back on track and adjusting your schedule accordingly.6. Find a Workout BuddyHaving a workout buddy can be a great way to stay motivated and accountable when it comes to exercise. Whether it's a friend, roommate, or classmate, having someone to exercise with can make workouts more enjoyable and help you stick to your routine. Plus, you can encourage each other to stay on track and reach your fitness goals together.7. Set Clear GoalsSetting clear goals for both academics and exercise can help you stay focused and motivated. Whether it's acing a test, completing a research project, or running a 5K, having specific goals in mind can give you something to work towards and keep you motivated. Write down your goals and track your progress to stay accountable and celebrate your achievements along the way.In conclusion, balancing academics and exercise is essential for maintaining a healthy lifestyle. By creating a schedule, being realistic, prioritizing self-care, incorporating exercise into your daily routine, staying flexible, finding a workout buddy, and setting clear goals, you can achieve this balance and ensure your overall well-being. Remember, it's all about finding what works best for you and making your health a priority in your busy schedule.。

The Art of Balancing Studies andExercise for a Healthy LifestyleIn the fast-paced world of today, where academic pursuits and career aspirations often overshadow our physical well-being, maintaining a healthy lifestyle can seem like a daunting task. Balancing studies with exercise is crucial for not only physical health but also mental clarity and emotional stability. This essay explores the importance of striking this balance and offers practical strategies for achieving it.Firstly, let's delve into the significance of exercise. Regular physical activity has numerous benefits, ranging from improved cardiovascular health to stronger bones and muscles. It boosts the immune system, reducing the risk of chronic diseases like heart disease and diabetes. Furthermore, exercise releases endorphins, the “happy hormones” that enhance mood and reduce stress levels. For students, this means better focus and concentration, leading to improved academic performance.On the other hand, studies are equally essential for personal growth and future success. However, it's easy toget caught up in the rat race of exams and assignments, neglecting our physical health. Prolonged sitting and lackof exercise can lead to stiffness, back pain, and even more severe health issues.So, how do we strike a balance? The key is toincorporate exercise into our daily routine. Start small by dedicating just a few minutes each day to physical activity. This could be a simple walk around the block, a few minutes of stretching, or even a quick session of yoga. Gradually, increase the duration and intensity of your workouts asyour fitness level improves.Another strategy is to schedule your studies and exercise alternately. For example, after a focused study session, take a break and go for a run or hit the gym. This not only gives your mind a rest but also helps to refresh and rejuvenate it.Moreover, it's important to prioritize sleep. Adequate rest is crucial for recovery and repair, both physicallyand mentally. Make sure to get enough sleep each night to ensure peak performance in both studies and exercise.Lastly, remember that balance is not about perfection but about finding what works best for you. Everyone's schedule, preferences, and fitness levels are different. Experiment with different strategies and find what suits you best.In conclusion, balancing studies with exercise is essential for maintaining a healthy lifestyle. By incorporating regular physical activity into our daily routine, scheduling studies and exercise alternately, prioritizing sleep, and finding what works best for us, we can enjoy the benefits of both academic success and physical well-being.**学习与锻炼的平衡：追求健康生活方式的艺术** 在当今快节奏的世界里，学术追求和职业抱负往往掩盖了我们的身体健康，维持健康的生活方式似乎是一项艰巨的任务。

人体每天必需营养（The body needs nutrition every day）I. nutrition(1) the concept of nutrition:Nutrition from food, food contains a variety of can provide the human body engaged in labor and maintenance of life, maintain body temperature, so that cell growth and development and repair, regulating the physiological functions of the material. Scientific diet should be diversified, not a partial eclipse. Mastering scientific diet and exercise is the only way to exercise.(2) the role of nutrition:Nutrition plays an important role in the maintenance of human health. Good nutrition can make the body and mind healthy, maintain normal weight, make people energetic and keep young forever. Too little nutrition can not meet the activities of the body, can lead to malnutrition, resistance to reduce, sickly. Excessive nutrition can also cause diseases, such as "modern civilization disease" and so on. Constitute a classification function that lacks excessive adult intake of food.Two and six nutrients:(1) carbohydrate (sugar)1, carbohydrate (sugar) in the human body ratio 1%-2%. Constitute a classification function, lack of excessive adultintake of food sources, the body needs 7.5G per kilogram of body weight per day.2. The most important monosaccharide in human body is glucose. Sugar: sugarMonosaccharides (glucose, fructose, galactose): sweet, easy to be absorbed by human body;The disaccharide (sucrose, maltose, lactose) by digestive enzymes, decomposed into monosaccharides;Polysaccharides (starch, cellulose) that are not sweet and are broken down into glucose by amylase.3, carbohydrates (sugar), the body's most important source of heat: 4 thousand calories per kilogram of carbohydrates. 40-50%, which accounts for the total energy source of the human body.4, carbohydrates (sugar) of human tissue cells, regulating fat metabolism and hepatic glycogen detoxification function, glycoprotein helps the liver can enhance human immunity.5, carbohydrate (sugar) intake is too little: people will cold, fatigue, functional decline, weight loss, hypoglycemia.6, excessive intake of carbohydrates (sugar): have high blood sugar, diabetes prone.7, carbohydrates (sugar) source: pure sugar (brown sugar, white sugar, honey, maltose), cereals (rice, millet, wheat flour,corn), dry beans (soybeans, beans), root vegetables (potatoes, taro) nuts (peanuts, chestnuts, etc.).8, carbohydrates (sugar) and exercise: modern people like to eat simple sugar is easier to absorb, in order to maintain muscle endurance, you can appropriately increase the amount of sugar intake,. But eating too much sugar is prone to obesity, and obese people should be properly controlled, but it is wrong to completely reject sugary substances or starches. The absorption process of polysaccharide is complex, and it is not easy to cause obesity.(2) fat1, the proportion of fat in the human body 10%-15%. In general food, the fat is the 20-25% of the total energy source of the human body (not more than 30%), and the body weight needs 1-1.5g per kilogram of body weight per day.2, glycerin three fat is the main component of fat. Category: saturated fats and unsaturated fats.3 saturated fats: animal fats (milk, lard, butter, chicken oil) contain too much to cause arterial stiffening or heart disease.4, unsaturated fats: such as vegetable fat (soybeans, peanuts, rapeseed, sesame, corn) containing acid, too much intake will cause obesity and other sequelae.5, the maximum energy supply per kilogram of fat produces 9 thousand calories per kilogram of fat.6, the role of fat: the protection of the skin, viscera, and maintain body temperature, the formation of human tissue cells, fat soluble vitamins dissolved, absorbed and used, affecting organizational function.7, lack of fat intake: it is not conducive to cell composition in human organs and tissues, is not conducive to the absorption of fat soluble vitamins.8, too much fat intake, easy to cause atherosclerosis and other diseases of the arteries. Blood lipids, high cholesterol, and have a close relationship. Too much fat can affect endurance, as well as protein and iron absorption.9, fatty food sources: pure oil (such as soybean oil, peanut oil, lard, butter, fish oil, rapeseed oil, sesame oil, corn oil), meat, egg yolk, nuts (walnuts, peanuts, melon seeds, butter and cream).(3) protein1, the proportion of 15%-18% in the human body. Daily weight per kilogram: 0.8-1.2 grams, athletes, etc.: 2.5 grams / kg weight.2 amino acids constitute the basic unit of protein. Classification: complete proteins and incomplete proteins.3, complete protein contains all the necessary amino acids for the human body (such as animal meat and so on, 98% can beabsorbed by the body). Incomplete proteins: such as vegetable proteins (80% can be absorbed).4, the human body has 8 essential amino acids, essential amino acids, the human body can not be synthesized, it is necessary to obtain from food (non essential amino acids 12).5. Protein provides energy: 4 thousand calories per kilogram of protein.6, proteins form tissue cells, participate in tissue repair, regulate human physiological function, growth and development, and affect the activity of nerve center. Control genetics and increase body resistance.7, protein: can cause endocrine disorders, digestion and absorption, weight loss, decreased resistance, fatigue, anemia, etc..8, excessive protein intake: protein can not be fully absorbed, heavy metabolic burden.9, the protein food source: pure oil (such as soybean oil, peanut oil, lard, butter, fish oil, rapeseed oil, sesame oil, corn oil), meat, egg yolk, nuts (walnuts, peanuts, melon seeds, butter and cream).10, protein and exercise: for a long period of time, should pay attention to prevent a large number of protein loss, the effective method is to appropriately increase the supply of carbohydrates. People involved in physical fitness, especiallyin the exercise of strength, need higher protein, especially in the early stages of exercise, to provide adequate protein.(4) mineralsMinerals: Minerals account for about 5-6% of the body's weight (carbon, hydrogen, oxygen, and nitrogen), accounting for 96% of the total weight. Minerals cannot be synthesized in humans and must be provided by food. Although the human body calcium 99%, 80%, 70% mg of phosphorus are concentrated in the bone, the bones and teeth, mineral acid can maintain the body balance, reduced intercellular fluid maintaining osmotic pressure in fat, protein and carbohydrate metabolism, maintain muscle, nerve, heart and normal function.Mineral and movement: as in exercise, energy metabolism is high, a lot of human sweat, the body of calcium, phosphorus, iron, potassium excretion and increased consumption, so exercise after exercise should be timely appropriate supplement, in order to maintain the body's normal metabolism machine can and physiological requirement.(5) vitamin - vitamin (Vitamin)Vitamin characteristics: vitamin also known as Vitamin, although in the human body is only a trace, as long as a small amount of animals can maintain normal growth, reproduction and health. Vitamins also have to go through a living organic diet, not a general carbohydrate, fat, protein, or mineral, and can maintain normal health by absorbing small amounts of it for normal metabolism.Vitamins have the following characteristics: most vitamins are not synthesized in the body and must be taken from food. It is not the structural component of the body, it does not provide energy. Some vitamins are unstable and can be destroyed during food processing and cooking. Intake should be appropriate. Less, the metabolism of substances in the body will be obstacles, prone to vitamin deficiency and its diseases. Excessive metabolism can cause disorders in the body, causing vitamin poisoning.Classification of vitamins:1, fat soluble vitamins (soluble in fat): vitamin A, vitamin D, vitamin E, vitamin K.2, water soluble vitamins (soluble in water): vitamin C, vitamin B group, vitamin PP, folic acid, biotin functions: 1) to promote growth and reproduction, 2) to strengthen the resistance, improve the organization function, 3) 4) 5) and promote appetite and maintain health, promote longevity and vigorous spirit etc..Vitamin A: helps the skeleton, the tooth development, protects the vision, the skin, strengthens the human body to resist and the immunity, the cancer prevention, the anticancer.Vitamin B1: coenzyme, involved in carbohydrate metabolism, heart preservation, maintenance of energy metabolism, improve exercise ability, prevent excessive fatigue, maintain the nervous system and increase appetite.Vitamin B2: maintaining normal metabolism of substances in the body, helps muscles develop, protect vision, skin and mouth.Vitamin B3: make people optimistic, treat mental illness, promote the nervous and digestive system, constitute coenzyme, participate in protein, carbohydrate, fat metabolism, and prevent cardiovascular disease.Vitamin B6: participates in the amino acid metabolism, the transformation synthesis, the maintenance brain normal function, maintains in the blood the magnesium, the cholesterol regular, prevents anemia, the decayed tooth, the kidney stone.Vitamin B12: hematopoietic function, prevent fatty liver, maintain the gastrointestinal tract, nervous system, bones of the normal function.Vitamin C: maintain metabolism, increase immunity, resistance, anti allergy, anti-cancer, detoxification, tooth, bone development, anemia, wound healing, eye care, beauty, beauty.Vitamin D: promote the body's absorption of calcium and phosphorus, help bones, teeth development, relaxation of nerves, relieve pain, vitamin A absorption, anti osteoporosis, conjunctivitis.Vitamin E: anti-aging, anti atherosclerosis, cardiovascular disease, improve resistance, anti-cancer, metabolism, increase endurance, improve physical strength, ease pain, liver detoxification function.Vitamin K: promote blood coagulation, stop bleeding, increase bone mineral density, promote ossification.Vitamins and sports: the metabolic characteristics of aerobic exercise are the consumption of heat energy and various nutrients, energy metabolism and aerobic oxidation. Therefore, in order to make the practice of hemoglobin and respiratory enzyme at a high level, in sugar reserves, improve exercise capacity, add more vitamin C, B1, B2, E and other related body needs vitamins.(6) water;The characteristic of water: water is the source of life. In the human tissue composition of the most content, accounting for about 60%-70% of the body weight, the human body has a very important role in maintaining normal physiological activities of the human body is an important nutrient.Water is widely distributed in the human body: 65-75% of muscle weight is water, and 25% of the weight of fat is water. Water is mainly stored in the intracellular fluid (of which about 62% is water) and extracellular fluid (such as more than 90% of the blood is water, as well as lymph, saliva, skin and kidney secretion of body fluids, etc.). Water is involved in the process of substance metabolism and contributes to the digestion, absorption, biological oxidation and excretion of substances. Regulate body temperature and maintain normal body temperature. It is a lubricant for organs, joints and muscles. Keep glands open and fill body fluids.The demand for water sources, body weight, heat of water demand and the consumption is proportional to the energy consumption of each card to 1 ml of water, per kilogram of body weight to 30-40 ml of water, if 70 kg person need 2100-2800 ml of water. Under normal circumstances, the amount of water entering and leaving the body is balanced. A healthy adult needs about 2000-2700 milliliters of water a day (including water, water in food, water from metabolism). If the water is too small, will make the blood concentration, viscosity increase high, is not conducive to the blood circulation and nutrient absorption. If you lose 20% of the body water, there will be life-threatening. In the hot, high temperature, fever and physical labor, the amount of water should be increased accordingly. Drinking water is a direct source of water needed by the body, such as drinking water or tea. But when the body is oxidized, it can also produce water, and the body needs water from the diet, such as water content of rice 15%, meat water content 50%.Relation between water and motion: during and after exercise. Weight loss due to sweating, 2-3% when the amount of blood drops, will significantly affect the body's ability to exercise and so on, so timely drinking water, and a small number of times for the principle. Should drink close to plasma penetration at the same time.Category: Health | | added to the collection | share to I Post Bar | browse (3205) | review (0) on a human body daily need the nutrition a papaya breast enhancement is not, but the recent Reader: after you log on, you came here.There are roughly three main nutrients required by the human body every day:Carbohydrates: carbohydrates, starch, etc.. Is the most basic human nutrition, it provides 50% of the body's energy source, each gram of carbohydrates can provide thousands of calories;Proteins: including plant proteins and animal proteins. The vegetable protein content is higher, such as beans, and the source of animal protein is meat, eggs and dairy products. Proteins form the basis of the human body. Blood, muscle, hormones, etc. are all proteins. In addition, in the case of carbohydrate and fat deficiency, protein can also provide energy, and each gram of protein can provide 4 thousand calories;Fat: the body's largest source of heat, but also constitute an important part of the human body structure. Human hunger, in particular, consumes large amounts of fat to provide energy, and each gram of fat provides 9 thousand calories. The main sources of fat are meat, eggs and so on.In addition to the above three categories, the body also needs vitamins and minerals to provide normal human physiological activities.Diabetic patients are particularly careful about the amount of calories they eat each day because of disorders of glucose metabolism and the combination of medications.First of all, according to the weight index to determine whatkind of body shape, and then according to the daily strength of the patient to determine how much calories per kilogram of body weight:Patients with standard weight, obesity, and weight loss required 15-20, <15, and 20-25 kcal of calories in bed rest patients, respectively;Light physical activities, such as office work and housework, require 30, 20-25 and 35 thousand calories, respectively;Moderate physical activity, such as drivers, farming activity respectively in 35 patients, 30, 40 thousand calories;Heavy physical activity, such as handling, loading and unloading patients required 40, 35, 45-50 kcal heat, respectively.For example, a 60 kg male patients with diabetes, 1.75 meters tall, engaged in office work (light physical activity), body mass index BMI = 60 / 1.752 = 19.6, between 18.5 and 22.9, is a normal size, the daily calories needed = 60 kg / kg = 1 million 800 thousand x 30 thousand card card.Thirty-onePeople should eat everyday together four foods, grains, dairy and meat, Vegetable & Fruit, every day to eat together, the daily required all the vitamins and minerals is not available, the four kinds of food, together with human daily needs seven nutrient water, carbohydrate, protein, fatty acid (fromVegetable & Fruit and beans), vitamins, minerals and fiber, therefore, the four kinds of food are called "balanced diet".A balanced diet is to eat seven nutrient Qi four types of food at each meal, but not into heat and oil, fiber foot, daily with grain and Vegetable & Fruit as the staple food, as the main source of daily energy, vitamins and minerals do not lack water, enough, enough protein.The corn starch, is the best energy substances in the human body; Vegetable & Fruit is the major source of fiber; milk and dairy products, in addition to providing protein, is the most important source of food of calcium and magnesium, but also an important source of water; meat, fish, eggs and beans in protein, constitute an important raw material of human body.A day before the two meal together to eat five hundred calories, eat breakfast and lunch how many calories can decide what to eat; food, also free to choose, but to eat all four categories of food, as long as the heat, oil, protein (meat) three is unfavorable choose food for each meal a big dinner space; vice versa.After each meal has been fixed, the diet can be considered for itself and varied. This diet is more likely to last long, so it has the greatest chance of success.。
