This can progress to type 2 diabetes. [2] Sleep variations, both in quantity and quality, may affect metabolic regulation in type 2 diabetes. Additional data has shown a correlation between sleep quality and type 2 diabetes risk. [4] Sleep loss can affect the basic metabolic functions of storing carbohydrates and regulating hormones.
The effect of sleep duration on somatic growth is not completely known. One study recorded growth, height, and weight, as correlated to parent-reported time in bed in 305 children over a period of nine years (age 1–10). It was found that "the variation of sleep duration among children does not seem to have an effect on growth."
"Adequate sleep allows the body to rest and repair itself, regulating hormones that influence blood pressure, inflammation and blood sugar levels—all of which are critically important for heart ...
Waking up earlier in the morning increases the response. [11]Shift work: nurses working on morning shifts with very early awakening (between 4:00–5:30 a.m.) had a greater and prolonged cortisol awakening response than those on the late day shift (between 6:00–9:00 a.m.) or the night shift (between 11:00 a.m.–2:00 p.m.). [12]
Stress hormones can also induce a state of chronic inflammation, [8] which can damage the body's tissues and organs and increase the risk of chronic diseases, such as arthritis, diabetes, and cardiovascular disease. These effects can make the body more vulnerable to chronic infections, such as bacterial infections and autoimmune diseases, which ...
In endocrinology, permissiveness is a biochemical phenomenon in which the presence of one hormone is required in order for another hormone to exert its full effects on a target cell. Hormones can interact in permissive, synergistic, or antagonistic ways. The chemical classes of hormones include amines, polypeptides, glycoproteins and steroids.
The β-AR pathway dysregulation has been implicated in the pathogenesis of heart failure. It has been found that certain changes to β-AR signaling result in reduced levels of β1-AR, by up to 50%, while levels of β2-AR remain constant. Other intracellular changes include a significant, sharp increase of GαI levels, and increased βARK1 activity.
Neuromodulation is the physiological process by which a given neuron uses one or more chemicals to regulate diverse populations of neurons. Neuromodulators typically bind to metabotropic, G-protein coupled receptors (GPCRs) to initiate a second messenger signaling cascade that induces a broad, long-lasting signal.
