Whilst most people flock to The Dead Sea to experience the surrealistic sensation of floating on water, few understand the chemical make-up of The Dead Sea.

The water of the Dead Sea contains 21 minerals including magnesium, calcium, bromine and potassium. 12 of these are found in no other sea or ocean and some are recognized for imparting a relaxed feeling, nourishing the skin, activating the circulatory system and for easing rheumatic discomfort and metabolic disorders. Comparison between the chemical composition of the Dead Sea to other lakes and oceans show that the salt's concentration in the Dead Sea is many times higher, and the bromine ions' concentration is the highest of all waters on earth. Chlorides neutralize most of the calcium ions in the Dead Sea and its surroundings. While in other seas NaCl is 97%, in the Dead Sea the quantity of the NaCl is only 12-18 percent. The water temperature goes from 19 degrees Celsius in February to 31 degrees Celsius in August.

1) The Dead Sea Waters:

The water of the Dead Sea is the world’s saltiest lake water, where the salinity of the
surface water reaches 290 gm/L, in comparison to the Red Sea salinity which reaches
40 gm/L only.
It offers an intense concentration of trace elements that are absorbed into the skin.
The water is a concentrated solution of chlorides, of calcium, potassium, sodium and
magnesium and high percentage of dissolved bromides. The concentration of magnesium known of its anti-allergic influence on the skin is fifteen times higher than the Mediterranean sea and the bromine is fifty times more.

The high salinity means high total dissolved salts ( T.D.S.), which reaches 335.214 P.P.M. ( par per million , compared to the Mediterranean water which is 80000 P.P.M. only.
The high salinity of the Dead Sea water is due to the tremendous evaporation process and the high amount of salts and mineral sediments.
The water density is consequently high and reaches 1.23 gm per cc. at 25 C.
Bathing in the Dead Sea is very beneficial for Psoriasis Arthritis especially in severe cases where movements are limited. The high specific gravity counteracts the weight of the body and allows floating without any effort. This is also an ideal medium for therapeutic exercises


Sun shine is filtered through the low situation of the Dead Sea ( additional 408 meters of air), then comes the vapor cover above the Dead Sea due to the high evaporation rate. This vapor serves as an additional filter to sunshine, and through this nature filter the (UV) ultra-violet ray is reduced as well as (UVB) rays responsible for the sun burn, therefore, the conditions are adequate for solar therapy which constitute a basic element of climate therapy is a available in the area.


Increased attenuation of a specific spectrum of ultra-violet radiation provides unusual therapeutic properties with an impressive impact on a number of diseases. At the Dead Sea the sun's ultraviolet rays are attenuated by three natural phenomena.

1)The longest solar ray optical path length as a result of it being the lowest terrestrial point (approx.-408 m) on the Earth. This results in enhanced scattering by air molecules, water vapor and aerosols.

2)A relatively dense haze, composed of aerosols (minerals), caused by continuous evaporation from Dead Sea.

Together these layers act as an unique filtering screen that reduces the intensity of the more harmful lower wave length UVB rays to a greater extend than the longer wave length UVA rays.

3) AIR

The Dead Sea region is of rich in oxygen – 10% more than at the Mediterranean sea level. This combined with extremely low polluting factors contribute towards remarkably pure air, which has proved to be great benefit for those suffering from respiratory conditions.

The atmosphere is also rich in bromide, which is about 15 times more than Amman for example – bromide acts as a natural Sedative allowing the nervous system to recover and rest, so restoring the mind and the body.


Temperature average in December is 24 degree and in August is 36.6 degree ( according to daily temperature in 1996). While humidity rate is very low, that is 45% during December and 32-3% during August during August (according to humidity in 1996). Precipitation rate is 100 mm. (1996) sea water temperature rate is 26.7 degree during December and 37.3 degree during August according to sea water temperature in 1996. This means that the climatic therapy conditions even in winter months are considered excellent and this makes the climatic therapy possible through out the year.


Due to the low situation of the Dead Sea the atmospheric pressure is as high as 800mm. Oxygen rate is 10% higher than the Mediterranean costs.


The chemical analysis of the Dead Sea mud shows that it contains many salts and minerals as the mud absorbs them from the water itself.
The mud is rich in magnesium, and natural bitumen, and silicates (Silicon compounds ): the latter has a mask effect to the skin useful for cosmetic purpose. The black color of mud absorbs high sun rays, so it acts as a photo-sensitizer when it is applied to the skin; also causing its temperature to rise and retain it's heat. The mud is capable of absorbing large amounts of water up to 70% of its volume. Mud baths are mainly useful for arthropathy, as they help in stimulation of blood circulation around the affected joints, and so mud packs are effective in case of psoriatic arthritis.
