Sit is the basic human break position. Weight is mainly supported by the buttocks that come into contact with the ground or horizontal objects such as the chair seats. The body is more or less erect. Sitting for most of the day can pose significant health risks, and people who sit regularly for prolonged periods have higher mortality rates than those who do not.
The kneeling shape in which the thighs near the horizontal and buttocks sit back on the heels, such as in Seiza and Vajrasana (yoga), is also often defined as sitting.

Prevalence
The British Chiropractic Association said in 2006 that 32% of the UK population spent more than ten hours per day sitting.

Position
On the floor
The most common way to sit on the floor is to bend the knee. One can also sit with unbalanced legs, using something solid as support for the back or leaning on one's arm. Sitting with bent legs can be done with legs that are mostly parallel or by crossing each other.
The commonly crossed position is with the bottom of both legs folded toward the body, crossed at ankles or calves, with both ankles on the floor, sometimes with legs tucked under the knees or thighs. This position is known in several European languages ​​as a tailor style, from a traditional tailor's work posture; compare bunion tailor. It is also named after the nomads who live in the plains: in the style of American Indian Indians, in many European "Turkish style", and in Japanese agura ( ?? < span>, Sitting styles of non-Han ethnicity (mainly Turks, Mongols and other Central Asians) ) . In yoga is known as sukhasana.
In the raised chair
Most elevated surfaces at suitable heights can be used as seats for humans, whether made for purpose, such as chairs, benches and benches, or not. While the butt almost always rests on the raised surface, there are many differences in how one can hold one's legs and back.
There are two main styles sitting on the raised surface. The first one has one or two feet in front of the sitting; in the second, sitting astride something, his legs tilted out on both sides of the body.
The feet can rest on the floor, or on the footrest, which can keep them vertical, horizontal, or at an angle between the two. They can also dangle if the seat is high enough. The feet can be stored right in front of the body, apart, or across the other.
The upper body can be held upright, lying sideways or backwards, or one can bend forward. Yoga, tradition and spirituality
There are many positions sitting in various traditions and rituals. Four examples are:
- Seiza ( ?? ) "sit right" is a Japanese word that describes the traditional formal way of sitting in Japan. The related position is a different ( ja "> ) , at the top of the foot lifted from the ground.
- Vajrasana (Diamond Pose) is a yoga posture (asana) similar to seiza.
- The lotus position involves breaking each leg on the opposite thigh so that the sole of the foot is facing upwards.
- The Burmese position, named for its use in a Buddhist statue in Burma, places both legs in front of the flank with knees bent and touching the floor to the side. The heel leads to the pelvis or upward, and the toes pointed so that the top of the foot lay on the ground. It looks similar to the crossed position, but the foot is not placed under the thighs of the next leg, therefore the foot does not pass. Instead, one foot is placed in front of the other.
In various mythology and folk magic, sitting is a magical act that connects people who sit with others, states or places.
Health risks
There is a significantly higher mortality rate among people who regularly sit for long periods of time, and the risk is not negated by regular exercise, even if it is lowered. Causes of mortality and morbidity include heart disease, obesity, type 2 diabetes and cancer, in particular, breast, endometrium, colorectal, lung, and epithelial ovarian cancers. The relationship between heart disease and diabetes and seizure death is well established, but the risk of cancer deaths is unclear. Time settling was also associated with an increased risk of depression in children and adolescents. The correlation between a particular sitting job and a higher body mass index has been demonstrated, but causality has not been established. There are several hypotheses that explain why sitting is a health risk. These include changes in cardiac output, vitamin D, inflammation, sex hormone activity, lipoprotein lipase activity, and GLUT4 activity due to long periods of muscle contamination, among others.
Sitting can occupy up to half of adult working days in developed countries. Program in the workplace to reduce the variation of sitting in the method. They include a sitting table, counseling, workplace policy changes, walking/standing meetings, treadmill tables, breaks, therapeutic ball chairs, and stepping equipment. The results of the program are mixed, but there is moderate evidence to suggest that changes to seats (adjusting seat biomechanics or using different types of seats) can effectively reduce musculoskeletal symptoms in workers who sit for most of the day.
Community health programs typically focus on improving physical activity rather than reducing sitting time. One of the main targets for this community health program is to sit in the workplace. For example, WHO Europe recommends that in September 2015 the provision of customizable desks in the workplace. In general, there is conflicting evidence about the exact risk of sitting for long periods of time. The 2015 Cochrane Review finds low-quality evidence for table sit-stands and/or counseling as an effective workplace program to reduce the total time spent sitting and the number of long-term sitting samples. As there are many new studies under way, the Cochrane Review is being updated, with the help of a crowd-funded campaign running from September 2015 to December 2015. Similarly, a recently published review concludes that interventions aimed at reducing off-the-job seating are just so effective.
