The notion of health can be confusing. Whether we feel good or not depends on our environment, and what we consider a good health condition may be a disease. A person's physical condition is only one factor in determining a person's health. Mental health refers to emotional and social resources. People need to be healthy to be productive and maintain relationships. In contrast, mental and emotional health are two very different things. This article will explain the differences and how we can achieve both. Wearable technology enables people to monitor their health. A range of products are on the market that can measure your heart rate, sleep, and recovery. These include responsive sportswear, wearable spaces, and smart clothing. The first of these devices, the smart watch, dominates the fashion accessory market. New developments fill the gaps in the health-driven industry. For example, the NADI X yoga pants have built-in sensors that vibrate to correct a person's posture. Similarly, Hexoskin manufactures socks that count calories. Health is a human right, defined by the World Health Organization in 1948. According to the WorldHealth Organization, everyone has the right to enjoy the highest possible standard of health, regardless of race, political belief, or economic status. In fact, many nation states have endorsed this concept as a part of their constitutions. They are now legally obligated to protect access to quality health, including providing for the determinants of it. This is because the world's population is increasing at an alarming rate, and the world is losing people to illness and disease.
