Cellular ageing is a natural process that gradually affects all of our cells. Although it is inevitable, it can be slowed down through a better understanding of its mechanisms and a healthy lifestyle. Discover how to preserve your vitality and take natural steps to support your cells on a daily basis.
Understanding the phenomenon of senescence
Cellular ageing refers to the gradual loss of the ability of cells to divide and function normally. Each cell has a limited number of divisions programmed into its genes. Beyond this cycle, the cell loses its ability to multiply and enters a phase of senescence, during which it remains alive but ceases to function properly. The cells eventually accumulate in the tissues, disrupting their proper functioning.
The consequences of cellular ageing are evident throughout the body. The skin becomes thinner and less elastic due to a decrease in collagen and elastin, while hair may fall out or become thinner due to a slowdown in hair follicle renewal.
Joints, meanwhile, lose flexibility: cartilage thins and ligaments become less elastic, leading to joint pain and stiffness. With age, the brain experiences a decrease in plasticity and a change in nerve signal transmission, which can impact memory and concentration.
Although these changes are natural, they can be exacerbated by external factors such as stress, pollution and an unbalanced diet. Combating cellular ageing, therefore, involves reducing these aggressions and strengthening the body's defence mechanisms.
What are the main causes of cellular ageing ?
Ageing is an inevitable factor: cellular repair mechanisms slow down and cells gradually accumulate alterations in their DNA and proteins. But other factors can accelerate this process.
One of the best-known mechanisms contributing to senescence is oxidative stress. Certain molecules produced naturally by the body, called free radicals, have an imbalance of electrons. To regain their stability, they “borrow” electrons from other neighbouring molecules, causing a chain reaction. The body normally has antioxidant defence systems, based on enzymes and protective molecules, to neutralise these free radicals. But when this balance is disrupted, oxidative stress sets in: it damages cell membranes, proteins and DNA, accelerating tissue ageing and the decline of certain biological functions.
Environmental factors also play a major role: prolonged exposure to UV rays, air pollution and ultra-processed foods. These factors promote glycation, a process whereby sugar binds to proteins in the body, altering their structure and function.
Chronic stress, lack of sleep and a sedentary lifestyle also contribute to cell damage. They disrupt tissue regeneration and weaken the body's natural defences.
How can cellular ageing be slowed down?
The best way to combat cellular ageing is to adopt a balanced lifestyle. Certain simple habits can strengthen cell resistance and stimulate natural regeneration mechanisms.
Antioxidants neutralise free radicals and protect cells from oxidative stress. They are found in many fruits and vegetables (berries, carrots, tomatoes, spinach, dried fruit), green tea, cocoa and olive oil. Unsaturated fatty acids, particularly omega-3s found in oily fish, nuts and flax seeds, support brain and cardiovascular health.
Physical exercise stimulates blood circulation, improves cellular oxygenation and strengthens the immune system. Choose walking, swimming, yoga or cycling, which promote cell longevity without traumatising the joints.
Sleep allows cells to repair themselves and contributes to better hormone regulation. Chronic lack of rest accelerates brain ageing. Relaxation techniques, such as meditation or deep breathing, limit the release of cortisol, the stress hormone.
Tobacco, alcohol, prolonged sun exposure and an unbalanced diet favour the production of free radicals and impair cellular function. Reducing these behaviours is essential for preserving the body's vitality.
Which dietary supplements can help combat ageing?
Dietary supplements can help combat cellular ageing. Arkopharma offers several natural solutions that promote your daily well-being.
The Longevity collection helps preserve cellular capital with tailored formulas based on antioxidant plants, vitamins and minerals that help protect cells against oxidative stress. Some products also combine other active ingredients such as resveratrol,
Forcapil® Age Protect helps reduce the appearance of visible signs, such as grey hair, preserves the vitality, shine and density of the hair, delaying the hair ageing process.
Stress accelerates cell senescence. The Sleep and Stress range combines melatonin, plants such as Passiflora and Lemon balm to promote relaxation and improve sleep quality, and nutrients such as magnesium to reduce fatigue.
Cellular ageing affects joint flexibility. The Chondro-Aid® range helps preserve cartilage mobility and structure thanks to vitamin C (collagen synthesis), combined with glucosamine and Boswellia, a plant known for its beneficial properties on bones and joints.
The Memory and Concentration product range supports cognitive function and helps maintain concentration and alertness thanks to recognised plants such as Ginkgo biloba and Bacopa, and B vitamins, which contribute to the proper functioning of the nervous system and reduce mental fatigue.
Food supplements are not a substitute for a varied and balanced diet, a healthy lifestyle or appropriate medical supervision, if your state of health requires it.
