Light therapy by adsgugus


More Info
									Light therapy or phototherapy (classically referred to as heliotherapy) consists of exposure to daylight or
to specific wavelengths of light using lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or
very bright, full-spectrum light, usually controlled with various devices. The light is administered for a
prescribed amount of time and, in some cases, at a specific time of day.

Common use of the term is associated with the treatment of skin disorders (chiefly psoriasis), sleep
disorder and some psychiatric disorders. Light therapy directed at the skin is also used to treat acne
vulgaris, eczema and neonatal jaundice. Light therapy which strikes the retina of the eyes is used to
treat circadian rhythm disorders such as delayed sleep phase syndrome and can also be used to treat
seasonal affective disorder, with some support for its use also with non-seasonal psychiatric disorders.

Other medical applications of light therapy also include pain management, accelerated wound healing,
hair growth, improvement in blood properties and blood circulation, and sinus-related diseases and
disorders. Many of these use low level laser therapy and red light therapy in the 620–660 nm
range.From a psychological and cultural perspective, a healthier diet may be difficult to achieve for
people with poor eating habits. This may be due to tastes acquired in early adolescence and preferences
for sugary and fatty foods. It may be easier for such a person to transition to a healthy diet if treats such
as chocolate are allowed; sweets may act as mood stabilizers, which could help reinforce correct
nutrient intake.[citation needed]

It is known that the experiences we have in childhood relating to consumption of food affect our
perspective on food consumption in later life.[citation needed] From this, we are able to determine
ourselves our limits of how much we will eat, as well as foods we will not eat - which can develop into
eating disorders, such as anorexia or bulimia This is also true with how we perceive the sizes of the
meals or

A low sodium diet is beneficial for people with high blood pressure. A Cochrane review published in
2008 concluded that a long term (more than 4 weeks) low sodium diet in Caucasians has a useful effect
to reduce blood pressure, both in people with hypertension and in people with normal blood pressure.

The DASH diet (Dietary Approaches to Stop Hypertension) is a diet promoted by the National Heart,
Lung, and Blood Institute (part of the NIH, a United States government organization) to control
hypertension. A major feature of the plan is limiting intake of sodium, and it also generally encourages
the consumption of nuts, whole grains, fish, poultry, fruits and vegetables while lowering the
consumption of red meats, sweets, and sugar. It is also "rich in potassium, magnesium, and calcium, as
well as protein". Evidence shows that the Mediterranean diet improves cardiovascular outcomes.
