Maintaining a Healthy Lifestyle Health is the condition of an organism or one of its parts in which it performs its vital functions normally or properly: the state of being sound in body or mind. Water is the most important and abundant inorganic compound in all living systems. Although humans might be able to survive for weeks without food, without water you would die in a matter of days. Nearly all the body’s chemical reactions occur in a watery medium. Water has many properties that make it such as indispensable compound for life. Nutrients are chemical substances in food that body cells use for growth, maintenance, and repair.The six main types of nutrients are water, carbohydrates, lipids, proteins, minerals and vitamins.
Three organic nutrients—carbohydrates, lipids, and proteins provide the energy needed for metabolic reactions and serve as building blocks to make body structure. Some minerals and many vitamins are components of the enzyme systems that catalyze metabolic reactions. Essential nutrients are specific nutrients molecules that the body cannot make in sufficient quantity to meet its needs and thus must be obtained from the diet. Some amino acids, fatty acids, vitamins and minerals are essential nutrients.Exercise is regular or repeated use of a faculty or bodily organ, bodily exertion for the sake of developing and maintaining physical fitness. Exercise is needed to stay healthy. And to live a full and active life. Aging is to become old, shows the effect or the characteristics of increasing age.
Generally tissues heal faster and leave less obvious scars in the young than in the aged. In fact, surgery performed on fetuses leave no scars. The younger body is generally in a better nutritional state, its tissue have a better blood supply, and its cells have a higher metabolic rate.Thus, cells can synthesize needed materials and divide more quickly. The extra cellular components of tissue also change with age. Glucose, the most abundant sugar in the body, plays a role in the ageing process.
As the body ages, glucose is haphazardly added to proteins inside and outside cells, forming irreversible cross-links between adjacent protein molecule. With advance age, more cross links form, this contributes to the stiffening and loss of elasticity that occur in aging tissue. Stress is a force exerted when one body or body part presses on, pulls on pushes against, or tends to compress or twist another body or body part.Some stress called eustress, prepares us to meet certain challenges and thus is helpful. Other stress, is called distress, is harmful. Any stimulus that produces a stress response is called stressor.
A stressor may be almost disturbance of the human body—heat or cold, environmental poisons, toxins given off by bacteria, heavy bleeding from a wound or surgery, or a strong emotional reaction. Your body’s homeostatic mechanism attempts to counteract stress. When they are successful, the internal environment remains with normal physiological limits. If stress is extreme unusual, or long lasting, the normal mechanism may not be enough.
