Elderly Exercise in Algeria

Algeria stretches from the Mediterranean coast to the Sahara, and for thousands of years its people lived in small, interdependent communities; fishers along the Northern shores, nomadic pastors moving through high plateaus, and desert tribes in the central Sahara. In all these societies, elders were not separated or placed into specialized care systems as is common in America and modern societies. Movement was not a scheduled activity and only a natural part of daily life; walking long distances for water, tending herds, gathering fuel, or participating in communal tasks. The elderly citizens contributed equally and were not significantly sedentary. 

From this perspective, the modern Western concept of “elderly exercise,” gym routines, fitness classes, and artificially regimented physical activity, does not translate into Algeria’s ancestral history. For most of Algerian history, elders did not “work out” or require exercise. They lived in alignment with the land, the sun, and the seasons and they did not suffer chronic illnesses like elderly people are falling prone to today. Their health was supported only by a circadian rhythm, some outdoor labor, and consuming local foods. 

Neurosurgeon Dr. Jack Kruse, found in his research on mitochondria that human biology and its regards to good health and longevity is shaped primarily by environmental signals such as light, temperature, and magnetism, not by exercise. So much so, that despite Western fitness propaganda the challenges facing elderly Algerians today arguably arise from a mismatch between ancient human adaptation and modern lifestyles: new apartments and cities in Algeria means more indoor living, less sunlight, and less natural movement. Urban areas now contain the majority of Algeria’s population, consisting of 75.7% of the population. Coincidentally, the country's diabetes prevalence increased dramatically (men from 16.1% to 26.4%, and women from 12.3% to 22.4%) from studies dating 2006-2019.

Archaeological sites such as Aïn Boucherit and Aïn Hanech containing bones dating to 1.8-2.4 million years ago, make Algeria one of the earliest known regions of hominin activity outside East Africa (Sahnouni et al.). Its later populations include the Iberomaurusian (c. 20,000 BCE) and Capsian people (c. 10,000 BCE). Algerian genetics have been passed down primarily from these groups which contributed to the ancestry of most of modern North Africans, particularly the Amazigh (Berber) peoples. Genetic studies show that these haplogroups such as U6, M1, and H- common in North Africa- reflect long-term adaptation to high UV exposure (Fadhlaoui‑Zid et al.). 

However, modern Algerian elders often live indoors and experience less sunlight exposure in modern developments. According to Kruse, chronic diseases arise when mitochondria receive signals that conflict with their evolutionary expectations. He argues that “you cannot out‑exercise a broken circadian environment,” emphasizing that light will shape mitochondrial function more fundamentally than movement. This helps explain why chronic disease in Algeria has increased even as life expectancy rises. 

Modern Algerian elders are experiencing the consequences of change in their natural environment. As some of the oldest continuously rooted populations in Africa, Algerians carry mitochondrial lineages that were shaped for a life lived largely outside, with natural light and constant low‑stress movement. The transition to indoor living, artificial lighting, and sedentary routines has created a biological mismatch that is causing the health problems in most countries elderly, including Algeria. This shift has contributed to the rise of what researchers call “hypokinetic diseases,” conditions driven by insufficient movement and the stresses of modern life. High blood pressure, for example, is now widespread across Algerian society and continues to grow as daily routines become more sedentary and psychologically demanding (Ezzedine Rami et al. 6). 

It is within the context of its own history of its people that the importance of movement should be understood: not exercise in the Western sense of gym sessions or workouts, but a return to the natural, sunlight‑based, low‑intensity activity that is conducive to longevity.
