Vitamin D, necessary for the body, is synthesized under the influence of sunlight. How long should it be disclosed to you? What time of day? Directions for use to relieve fatigue or irritability.
The observation is simple: you feel tired all the time, despite moments of rest and a good night’s sleep. You may be deficient in vitamin D. And with good reason, fatigue is the main symptom of this deficiency in the body. To remedy this, you can focus on the contents of your plate, particularly digging into cod liver oil, salmon, sardines or even eggs, but also getting some sun. This week’s spring weather couldn’t be better, provided you’re properly exposed. General Practitioner and Nutritionist Faiza Bossi instructs.
A short regular exhibition
For vitamin D supplementation, the ideal is obviously exposure as regularly as possible. According to Faiza Bossi, a base of one to two sun sessions per week for 15-30 minutes is a good minimum. “UVB rays pass through the skin and then react with a cholesterol derivative that is naturally present in the body to finally produce vitamin D. The skin is then a sensor and the converted vitamin diffuses throughout the body. “The whole body. “, the doctor explains.

However, the duration of exposure should be determined by your skin type, as not all skin types metabolize the vitamin in the same way. “There are five types of phototypes, from red skin to black skin,” says the doctor, “and they all have different sensitivities. Darker skin will take longer to exfoliate than lighter skin.”
The art of making yourself look good
To do it right, keep your face, hands and, if possible, your forearms in direct sunlight. “These are both the simplest areas to expose every day, and this limits the places that can get tanned,” adds the expert. This way you can benefit from the rays without putting your skin at risk.” We also choose the time of day when light rays are most important, from 11am to 2pm. Getting into rest mode is important, “if you’re working, for example, it can be tiring to fight the heat,” Faiza Bossi explains.
And what about sunscreen lotions for sun protection? They block the production of vitamin D, but this does not justify their neglect. “There is a benefit-risk effect. It’s good practice to stay in the sun for short periods of time using a light sun protection factor.
Many advantages
The benefits of vitamin D are many and quickly felt on morale, skin tone, hair and nail quality. Admission is also necessary to avoid getting sick. The doctor reminds. “Vitamin D strengthens the body’s immunity and therefore prevents infections, whatever they may be. When we’re flawed, we’re more vulnerable to viruses and bacteria.”
In general, “the effect of vitamin D is visible to the naked eye. In addition to fighting fatigue, it highlights the appearance of brittle hair and brittle nails and restores a radiant look to dull skin,” describes Faiza Bossi. This is why some of us, especially children, take supplements in the form of ampoules during the winter.
