Earthing
Earthing may refer to: * Ground (electricity) in electrical engineering ** Earthing system, how to connect an electrical circuit to ground * , an alternative medicine practice * Nature therapy, another alternative medicine practice * Hilling Hilling, earthing up or ridging is the technique in agriculture and horticulture of piling soil up around the base of a plant. It can be done by hand (usually using a hoe), or with powered machinery, typically a tractor attachment. Hilling burie ...

Earthing System
An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the Earth's conductive surface, for safety and functional purposes. The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. Regulations for earthing systems vary among countries, though most follow the recommendations of the International Electrotechnical Commission (IEC). Regulations may identify special cases for earthing in mines, in patient care areas, or in hazardous areas of industrial plants. In addition to electric power systems, other systems may require grounding for safety or function. Tall structures may have lightning rods as part of a system to protect them from lightning strikes. Telegraph lines may use the Earth as one conductor of a circuit, saving the cost of installation of a return wire over a long circuit. Radio antennas may require particular grounding for operation, ...

Ground (electricity)
In electrical engineering, ground or earth is a reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. Electrical circuits may be connected to ground for several reasons. Exposed conductive parts of electrical equipment are connected to ground, to protect users from electrical shock hazard. If internal insulation fails, dangerous voltages may appear on the exposed conductive parts. Connecting exposed parts to ground will allow circuit breakers (or RCDs) to interrupt power supply in the event of a fault. In electric power distribution systems, a protective earth (PE) conductor is an essential part of the safety provided by the earthing system. Connection to ground also limits the build-up of static electricity when handling flammable products or electrostatic-sensitive devices. In some telegraph and power transmission circuits, the ground itself can be used as one co ...

Nature Therapy
Nature therapy, sometimes referred to as ecotherapy, forest therapy, forest bathing, grounding, earthing, Shinrin-Yoku or Sami Lok, is a practice that describes a broad group of techniques or treatments to use nature to improve mental or physical health. Spending time in nature has various physiological benefits such as relaxation and stress reduction. History In the 6th century BCE, Cyrus the Great planted a garden in the middle of a city to increase human health. In the 16th century CE, Paracelsus wrote: "The art of healing comes from nature, not from the physician." Scientists in the 1950s looked into why people chose to spend time in nature. The term '' Shinrin-yoku'' () or forest bathing was coined by the head of the Japanese Ministry of Agriculture, Forestry, and Fisheries, Tomohide Akiyama, in 1982 to encourage more visitors to forests. Health effects Mood 120 minutes in nature weekly could improve health and well-being. As little as five minutes in a natural sett ...
