13 March: what is celebrated today
The calendar also knows how to speak in whispers. 13 March does not call for loud celebrations, but for attention: to inner rhythms, to the organs that sustain our everyday lives without seeking the spotlight, to health that is cared for before it begins to fail. Sleep, the brain and vision meet today in one idea: prevention is a form of self-respect.
World Sleep Day
World Sleep Day is celebrated every year on the Friday before the March equinox — or the third Friday of the month — since 2008. In 2026, it falls on 13 March under a motto as clear as it is necessary: «Sleep Well. Live Better». It is not an optimistic slogan, but a statement supported by decades of scientific research.
Sleeping well does not mean merely accumulating hours of rest. It means respecting the body’s cycles, allowing sleep to be deep, continuous and restorative. However, in a hyperconnected society, rest is often relegated, interrupted by screens, irregular schedules and constant mental stimulation.
The consequences of poor sleep go far beyond tiredness. Mood disturbances, concentration problems, weakening of the immune system and a greater risk of chronic diseases are part of the silent price of lack of sleep. This day invites us to restore rest as a pillar of health, as essential as food or movement.
World Brain Week
At the same time of year, World Brain Week takes place, usually celebrated between 10 and 16 March. Since 1996, this international initiative has sought to bring neuroscience closer to everyday life and remind us that the brain is not only an organ, but the centre of our identity, memory and emotions.
To speak of the brain is to speak of how we think, feel and make decisions. It is also to recognise that mental health cannot be separated from physical health. Chronic stress, lack of rest and information overload directly affect its functioning, even if their effects are not always immediate.
This week proposes a more conscious view of our daily habits: learning, resting, managing emotions and caring for the mind as parts of the same equation. In dialogue with World Sleep Day, the message becomes clear: there is no healthy brain without sufficient rest.
World Glaucoma Week
From 9 to 15 March, World Glaucoma Week is celebrated, dedicated to raising awareness of one of the main causes of irreversible blindness in the world. Glaucoma progresses silently, without clear symptoms in its early stages, which means many people discover the disease when visual damage is already significant.
The key to this week is prevention. Regular ophthalmological check-ups, especially from the age of 40 or for people with a family history, can make the difference between retaining and losing sight. Detecting it in time does not mean curing it, but it does mean slowing its progression and preserving quality of life.
In the context of this 13 March, World Glaucoma Week adds to a broader reflection: caring for what works quietly. Sight, like sleep or the brain, sustains our relationship with the world and deserves attention before it begins to fail.
