HELIOTHERAPY OR SUNLIGHT THERAPY

Phototherapy

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  administered for a prescribed amount of time

Heliotherapy                                                       


The treatment of disease through exposing the body to sunlight.

or

A method of treating illness through exposure to the rays of the sun.

Heliotherapy (also called climatotherapy) makes simple use of intentional direct exposure to natural sunlight to get the therapeutic benefits of the included ultraviolet radiation.

The use of heliotherapy began a long time ago when used in India, China, and Egypt to treat diseases, including psoriasis.

Sunlight called Electro Magnetic radiation – Sun emitted the energy of many different wavelengths. Such energy provides us with the heat and light we need, as well as, delivering damaging UV rays.

In addition to UV, Visible light & IR, Sunlight composed of a host of other solar rays such as cosmic rays, gamma rays, x-rays, radio-frequency radiation; but these present in too small quantities and have too low energy to affect our skin.

Electro – Magnetic Radiation

Cosmic Rays/ Gamma Rays/ X-Rays :

Dangerous and potentially cancer producing but penetrates to earth only an insignificant amount. X-rays used artificially in medicinal diagnosis

UV Radiation :

Causes short & long-term damage to exposed living matter, particularly causing in humans- sunburn, photo-aging and skin cancers.

Visible Light :

Allows us to see, enables plants to create food molecules; lifts human mood-photophobia)

IR Radiation :

Warms our bodies.

Radio-frequency Radiation :

no known significant effect.

 

Why Sunlight is Important?

 

The energy from sunlight essential for the evolution of life on earth. Without sunlight human beings, plants and animals cannot survive.

Visible light needed for photosynthesis (through food chain)

IR light gives warmth, which we need to live

Sun Bath

  • all ages and both genders.
  • Early morning and evening sunbath the best.
  • Bright sunlight not advisable.
  • 10 minutes to 15 minutes of daily exposure to sunlight useful

Drink sufficient amount of water before sunbath and if needed during sun bath.

Heliotherapy used for:

Acne, psoriasis and other skin disorders

Muscular stimulation and relaxation

Seasonal Affective Disorder

Reducing body odor

Boosting the body’s immune system for the treatment of AIDS

Reducing bacteria count by as much as 50% from infections

Decontaminating blood transfusions

DNA repair

Irradiating the blood of cancer patients

Hyperbilirubinemia (neonatal jaundice)

One Research revealed that in,

Bright light therapy may ease Parkinson’s disease reducing patients’ tremors.

Also in Alzheimer’s disease positive impact of light therapy on overall cognitive function found.

Types of Sun Bath

General sunbath

Indirect sunbath

Localized sunbath

Plantain sunbath

1.General Sun Bath (Direct Sun Bath)

This type of Sunbath popular in Western countries. They practice in the seashore and on the banks of Rivers.

This bath should take after 1 to 2 hrs of the sunrise with minimal clothing.

Lie down on the sand of seashore (or) lie down on a bed sheet.

Before taking Sun bath drink sufficient amount of Water.

Picture8

2. Indirect Sun Bath

Same way as General Sunbath, but in this type, the whole body should be covered with thin white cotton clothes.

Picture7

3. Localized Sun Bath

In this type exposure of Sun to a positive area of the body for treatment, other parts of the body covered by a wet sheet. Effective in respiratory diseases and neonatal jaundice.

4.Plantain Leaf Bath / Banana Leaf Sun Bath

Same as General Sun Bath, the body covered with banana leaves and then exposed to sunlight.

Techniques Of heliotherpy:

Photodynamic therapy:

This treatment is based on a photo-sensitive liquid that is injected into the body. this liquid is attached to the unhealthy cells of the body. When it is exposed from outside to strong light it becomes solid, and thus it kills the unhealthy cells.

    Light boxes

The production of the hormone melatonin, a sleep regulator, is inhibited by light and permitted by darkness as registered by photosensitive ganglion cells in the retina.

During treatment, the patient’s eyes are to be at a prescribed distance from the light source with the light striking the retina. This does not require looking directly into the light.

Indications for Heliotherapy:

A common use of heliotherapy associated with the treatment of skin disorders mainly psoriasis, sleep disorder, and some psychiatric disorders.

Light therapy directed at the skin 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.

boost immunity:

The sun broad immune-boosting effect.

It stimulates our pituitary gland – the master switch of our endocrine system. This produces hormones which determine the strength and speed of our body’s immune responses.

Beat depression and insomnia:

Beat depression and insomnia:

Our pineal gland controls our sleep/wake cycles secreting the hormone melatonin which stimulates our body to sleep.

Many people need more sleep and prone to depression especially during the winter because of increased melatonin production.

Sunlight keeps us awake inhibiting melatonin production

Better sleep and a sunny day naturally enhance energy levels. For the same reasons people tend to sleep more in winter – increased melatonin – lack of sunlight makes us drowsy throughout.

Treatment of osteomalacia:

Osteomalacia the softening of the bones caused by defective bone mineralization as Vit D plays a good role in bone mineralization.

Strengthen bone:

Vitamin D also needed for bone health. It stimulates and enhances the absorption of calcium from our diet into our bones.

RICKETS:

as it mainly due to deficiency of Vit D so it is treated with heliotherapy

To treat skin disorders:

psoriasis and acne vulgaris treated by light therapy because it increases the immune response.

Musculoskeletal system:

reduces muscle spasm improving circulation and promote relaxation due to the heat of light therapy.

Picture3

NEONATAL JAUNDICE :

  • also known as hyperbilirubinemia
  • heliotherapy used to treat this because it breaks the bilirubin and maintain its normal amount.

Eczema  Acne vulgaris

Contraindications for Heliotherapy:

Few absolute contraindications to light therapy.

(1)Xeroderma pigmentosum.

(2)disorders predisposing to sun-induced cancers.

Contraindications

Picture2

Systemic lupus erythematosus:

because the autoimmune disease that can damage tissues of any part of a body and this is treated by immunosuppressant as heliotherapy promotes immune response so contraindicated.

Medications :

antibiotic and anti-inflammatory drugs increase the photosensitivity so contraindicated if a person taking these medicines

contraindications

Eye disease:

because the light will disturb the eye that is affected and heat can cause burn to diseased eye.

Risk Factors for Heliotherapy:

Ultraviolet light causes progressive damage to human skin. This is mediated by genetic damage, collagen damage, as well as the destruction of vitamin A and vitamin C in the skin and free radical generation.

Ultraviolet light also knew to be a factor in the formation of cataracts.

Side Effects:

Side effects of light therapy for sleep phase disorders include jumpiness or jitteriness, headache, and nausea.

Somnondepressiveve physical complaints (such as poor vision and skin rash or irritation) may improve with light therapy.

Caution:

The same invisible ultraviolet radiation that treats psoriasis is also responsible for many undesirable skin changes as well. These same wavelengths of light can also cause skin aging, wrinkling, tanning, burning and skin cancer.
