Are there really effective ways to boost your immune system?

Morning exercises, half an hour (at least) walking in the fresh air and before going to bed, vegetables, fruits, apples, especially nuts, low-fat cottage cheese, buckwheat porridge with vegetable oil (any, preferably flaxseed). If possible, less meat, from milk best of all kefir ... I. natural green tea with lemon and a little honey .... And .. smile, gentlemen, smile !!!

Hardening, physical activity, balanced diet, more vitamins in the diet (especially D3), and less anxiety. You can selectively, but it's better all at once) The main thing is without fanaticism!

Hardening, for example, a contrast shower. Plus, proper and balanced nutrition. And I also take Babisan D3. 80% of the population of Russia is deficient in vitamin D and therefore have problems with immunity

Strengthening immunity means strengthening non-specific immunity. Immunity, as you know, is composed not only of immunocompetent cells, but also of the general resistance of organs. General resistance is high due to two factors:

1. Diet. In other words, the balance of vitamins, micro- and macroelements, B / W / Y. To maintain balance, you need to take all this in optimal quantities, in no case in the form of dietary supplements (see why - see below), but only in the form of food as part of a properly selected diet.
2. Hardening. There are studies that biophysically explain the effectiveness of hardening by changing the protein-lipid ratio of plasma membranes of cells under moderate stress exposure. This strengthens cells to nonspecific irritants and infectious agents. In addition, it has a positive effect on the psyche, thereby reducing the effect of nocebo.
   But I do not recommend taking vitamins and other dietary supplements:

• The dosage forms of vitamins, μE and FCE have low bioavailability, that is, they are poorly absorbed (due to the wrong ratio, wrong combination with food intake, improper intake by the time of day, dissolution in the wrong department, locally increased concentration and shift in kinetics first order to zero, and so on).
• There is a concept of hypervitaminosis (as well as various hyperelementoses), which usually means acute (subacute) hypervitaminosis with the development of symptoms within weeks to months - however, there is also chronic hypervitaminosis with the development of systemic disorders over decades. So, there are studies showing that the systematic intake of vitamin A in the form of dosage forms reduces life expectancy and increases the likelihood of developing tumor processes. The same applies to hyperelementosis.

Vitamins to drink, eat meat (optional), salads, berries, fruits and vegetables. Do sports and temper yourself in all sorts of baths (in the shower, too, you can). This is all effective, but you may not notice the result initially because this process is not 1 day and not 1 month

By the way, also fish oil, nuts. Google, everything you need is useful and in moderation <3
