One third of low-birth-weight neonates – infants weighing less than 2,500 g (5 lb 8 oz) – are small for gestational age. [ citation needed ] There is an 8.1% incidence of low birth weight in developed countries, and 6–30% in developing countries.
Thermoregulation, or body temperature control, in animals, including humans. Subcategories. This category has the following 3 subcategories, out of 3 total. D.
Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [2] Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion.
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
Satisfaction with the thermal environment is important because thermal conditions are potentially life-threatening for humans if the core body temperature reaches conditions of hyperthermia, above 37.5–38.3 °C (99.5–100.9 °F), [11] [12] or hypothermia, below 35.0 °C (95.0 °F). [13]
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
The pulse also varies with age. A newborn can have a heart rate of 100–160 bpm, an infant (0–5 months old) a heart rate of 90–150 bpm, and a toddler (6–12 months old) a heart rate of 80–140 bpm. [12]
During the Tang dynasty, Chinese physician Sun Simiao is believed to have written the first nutrition guide in traditional Chinese medicine.In his book, Precious Prescriptions for Emergencies (Chinese: 備 急 千 金 要 方; pinyin: Beiji qianjin yaofang), the chapter "Dietary Treatment" (Chinese: 食 治; pinyin: Shiji) contains sections describing the effects of eating fruits, vegetables ...
