Merzouga is the primary reference in Morocco for sand burial therapy. Its sands are distinguished by a high silica content and fine minerals, as well as by high surface temperatures and intense dryness. The treatment consists of burying the body up to the neck for 10 to 20 minutes under the supervision of local experts, followed by thermal wrapping and the consumption of desert plant infusions.
This technique is beneficial in treating rheumatism, joint pain, sciatica, and certain peripheral nerve disorders. The best therapeutic season runs from June to September, when the sand reaches its ideal temperature (around 45°C). The silence of the desert environment adds a psychological therapeutic dimension of great importance.
Therapeutic Benefits
Hot sand treatment in Merzouga is traditionally used to relieve pain related to joints and the nervous system. Consulted sources indicate that the practice typically lasts 10 to 20 minutes, with local supervision, followed by rest, warmth, and hot drinks or infusions after the session. The beneficial action of this sand therapy (also called psammotherapy or arenotherapy) relies on the heat and weight of the sand, which increases blood pressure and produces a soothing warmth without causing burns, similar to the effect of a sauna.
Season and Precautions
The most favorable period is between late June and late September, when the sand’s heat reaches its maximum. Consulted reports and articles also mention important health precautions, including prior assessment of the patient’s fitness, hydration, and avoidance of certain conditions such as heart disease or diabetes. Medical supervision is recommended, as the risk of heatstroke can be significant, and some people (e.g., those with asthma, heart conditions, or diabetes) should not undergo the treatment.
Local Use and Tourism
Merzouga is widely recognized as a therapeutic tourism destination linked to sand baths, and its reputation has been reinforced through reports on the treatment of rheumatism and joint disorders. The region attracts both a local audience and visitors seeking natural care in a very quiet Saharan setting. Most guesthouses in Merzouga now offer sand therapy, often managed by former nomads, making it a major axis in the development of health tourism in the area.
