booster ses defenses immunitaires

Beat the post-holiday blues: draw on your recharged batteries to boost your immune system!

The holidays are drawing to an end, and you’re relishing that sense of well-being and renewed vitality. Tanned and rested, you're in great shape! But how can you prevent all this positive energy from wearing off during the first few days back at the grindstone? The secret is to preserve and strengthen your immune defences. They act as a shield against the minor health problems that often plague your return to the daily routine.

Fill up on vitamin D: your summer health boost

During your holidays, you've had your fill of sunshine, and with it, precious vitamin D. This "sunshine vitamin" plays a crucial role in the proper functioning of your immune system. It’s especially helpful in allowing your immune cells to beat off infections and reduces the risk of respiratory infections.

Just take Marie, an executive with a Luxembourg bank, who’s just back from two weeks in Greece. Her tanned complexion tells you that she spent her time basking in the Mediterranean sunshine. Without knowing it, she has built up precious reserves of vitamin D, which will help her get through the first few months of autumn with greater resistance to seasonal viruses.

But be warned: these reserves are not endless. From September onwards, we recommend that you maintain a sufficient intake of vitamin D, either through your diet (oily fish, eggs, mushrooms) or in the form of tablets which can be prescribed by your GP. 

 

Transforming rest into immune strength

When you wind down during your holidays, you are actually building up your health reserves. The restorative sleep and absence of stress caused by the mental load have allowed your body to regenerate in depth. Your immune cells have a chance to renew themselves and your natural defences are strengthened.

To draw on this new-found sense of well-being, here are a few simple but effective tips to follow:

Keep to a regular sleep pattern

Even if going back to work means a change of schedule, try to maintain a regular sleep cycle. Seven to eight hours a night are still recommended if you want to get the most out of your immune system.

Maintain a balanced diet

Fill up on foods rich in antioxidants, vitamins and minerals that fuel your immune system.

Make physical activity part of your routine

Long walks on the beach or mountain hikes have stimulated your blood circulation and enhanced your cardiovascular system. Regular physical activity, even in moderation, helps maintain a high-performance immune system.

You can simply incorporate this into your daily routine by walking to work or getting off a stop before the bus or tram - these are habits that will do you a world of good. 

Manage the back to work stress

The return to reality can sometimes be brutal. Your e-mail inbox is full, you've got meetings to catch up on, you're always on the go... Chronic stress is the number one enemy of your immune system. It weakens your natural resistance and makes you more vulnerable to infections.

Take the example of Thomas, an IT consultant, who got back from his holiday in Spain only to be greeted with three urgent projects. Within a few days, he came down with a persistent cold and felt tired for no reason. Weakened by the stress of his return journey, his immune system was unable to fend off the first autumn viruses.

To avoid the same fate, allow yourself a "gradual re-entry":

  • Plan your return a few days before you go back to work
  • Set priorities to avoid overload
  • Allow yourself some time out, however short
  • Try out some relaxation or meditation techniques

Despite all your efforts to keep your immune system strong, health problems can still strike. Hence the importance of comprehensive health cover tailored to your needs.

Simple steps to help you get back into shape

Beyond the theory, a few simple practical measures can make all the difference:

Stay sufficiently hydrated

Water helps eliminate toxins and keeps your organs working properly. Aim for 1.5 to 2 litres a day.

Ventilate your home

Fresh air limits the spread of viruses and bacteria. Open your windows every day, even in winter.

Wash your hands regularly

This simple measure remains one of the best barriers against infection.

Listen to your body

More tired than usual, low morale, recurring minor ailments... These are all signals that your body is sending you. Don’t hesitate to consult a health professional if necessary.
