The resort of Narechen is set
amid magnificent pine forest on the lovely Assenitsa river
in the Rhodopean mountain. Narechen is situated at an altitude
of 620-660 m. The climate is transitional between the temperate
continental zone and the country's southernmost regions with
strong Mediterranean influence. The average air temperature
is about 10C; and the average July temperature, about 19-20C.
Thanks to the fresh mountain
breezes the summer is not excessively hot and the weather
is particularly fine. The winter is mild to moderately cold
with many clear days. The autumn is long, warm and sunny.
The relative air humidity is moderate ( about 70 per cent
). The air is extremely clean and rich in negative iron ions
which have a beneficial effect on the mucous lining of the
respiratory tract and on the nervous system.
The hypothermic waters contain
radon, sulphates and hydrocarbonates of sodium and calcium,
silicon and small amounts of fluorine, and have a weak alkaline
reaction. They are clear, colourless and palatable. The radon
content ranges from moderate to high. The mineral waters of
Narechen contain a number of trace elements such as lithium,
barium, zinc, manganese and titanium, which are essential
for the body regulatory processes. The influence of the mineral
waters is especially favourable for the prophylactics of functional
disturbances of the nervous system nature. Their influence
on diseases of the cardiovascular system and body metabolic
processes is also very good. Specialists have proved the effective
influence of the Narechen mineral waters on stomach, intestine,
bilis, pulmonary, kidney and urological diseases.
