This was the most common position, and is especially popular with women. Log (15%) – lying on one's side with the arms down the side. Yearner (13%) – sleeping on one's side with the arms in front. Soldier (8%) – on one's back with the arms pinned to the sides. Freefall (7%) – on one's front with the arms around the pillow and the head ...
Sleep position and snoring. It is recommended that people at risk of obstructive sleep apnea sleep on their side [4] and with a 30° or higher elevation of the upper body. [5] Snoring, which may be (but is not necessarily) an indicator of obstructive sleep apnea, may also be alleviated by sleeping on one's side. [6]
Free fall. In classical mechanics, free fall is any motion of a body where gravity is the only force acting upon it. A freely falling object may not necessarily be falling down in the vertical direction. An object moving upwards might not normally be considered to be falling, but if it is subject to only the force of gravity, it is said to be ...
Obstructive sleep apnea (OSA) is a form of sleep apnea that occurs more frequently when throat muscles relax [7] and is most severe when individuals are sleeping in the supine position. Studies and evidence show that OSA related to sleeping in the supine position is related to the airway positioning , reduced lung volume , and the inability of ...
Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) [ 1 ] or, incorrectly, zero gravity. Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero.
High-altitude military parachuting, or military free fall (MFF), is a method of delivering military personnel, military equipment, and other military supplies from a transport aircraft at a high altitude via free-fall parachute insertion. Two techniques are used: HALO (high altitude – low opening, often called a HALO jump) and HAHO (high ...
Orthopnea or orthopnoea [1] is shortness of breath (dyspnea) that occurs when lying flat, [2] causing the person to have to sleep propped up in bed or sitting in a chair. It is commonly seen as a late manifestation of heart failure, resulting from fluid redistribution into the central circulation, causing an increase in pulmonary capillary pressure and causing difficulty in breathing.
Proprioception is from Latin proprius, meaning "one's own", "individual", and capio, capere, to take or grasp. Thus to grasp one's own position in space, including the position of the limbs in relation to each other and the body as a whole. [citation needed]
