The best ideas for boosting your immunity for summer

• •

Research into maintaining and strengthening the immune system has been ongoing for a long time. However, supporting your body isn't actually difficult. There are four aspects that contribute to strengthening your immune system.

The issue of maintaining and strengthening the immune system is especially acute during the fall, winter, and spring. So how can we support it and prevent it from weakening? During the period when flu and other viral infections are rampant, the simplest things can help support our bodies.

1. Three days of fasting will completely reboot your immune system.

If you're still unsure whether fasting is beneficial, we'll explain why it's worth the effort for just three days.

Social media will soon be flooded with posts offering ten life hacks on how to lose weight before summer. In the spring, it's truly beneficial to shed a few extra pounds gained over the winter (after all, you had to bundle up). Some people prefer fasting, others stick to a long diet, and still others starve themselves. Many doctors consider "fasting" a fashionable trend that not only doesn't help with weight loss but also carries health risks. Firstly, after fasting, the body will begin to store fat with redoubled vigor because it's stressed and afraid of being left without food again. Secondly, in just a day or two, a person will lose a multitude of nutrients—protein, iron, vitamins—and this will certainly not be beneficial.

The University of Southern California conducted a study in which participants regularly fasted for two to four days for six months. As a result, their immune systems significantly improved, experiencing a major reboot. Furthermore, each participant's body began producing significantly more protein kinase A—a deficiency of this protein is directly linked to the development of cancer. Cellular and immune system regeneration is also associated with slower aging and overall improved well-being.

It works like this: the body experiences stress and begins to use up its reserves of glucose, fat, and protein, activating white blood cell activity. A shortage of white blood cells occurs, and the body begins to urgently produce new immune cells, performing a complete reboot.

Two or three days a month is a perfectly manageable sacrifice for boosting your immunity and shedding a few extra pounds. However, it's important to remember that you shouldn't eat pizza or burgers on the first day after a fast. Ease out of the fast gradually and replenish your body's lost nutrients. Eat fruits, vegetables, fish, and meat. We also advise against exercising during a fast: physical activity can cause a significant drop in blood sugar, leading to dizziness and weakness.

2. Healthy porridge can be delicious

A significant mistake many parents make is the firm belief that children will eat something just because they're told to. And it doesn't matter that it's not tasty—the important thing is that it's healthy.

And then, for almost the rest of their life, the person will experience a severe aversion to any kind of porridge and other unhealthy eating habits. And the fact that porridge can actually be delicious is perceived as a true revelation.

Millet

It's not a very common porridge, which is a shame. The fact is, it contains a huge amount of manganese, zinc, and vitamin PP. Moreover, the millet used in its preparation can be added to almost any soup for added health benefits and thickness. Just remember to rinse it, as millet can go rancid with prolonged storage due to its high fat content.

The porridge is easy to prepare: add the rinsed grains to boiling salted water, simmer for 5 minutes over low heat, stirring constantly. Then, drain about half the water and cook until done. The flavor, however, can be enhanced with dried fruit, dried apricots, honey, or even sugar.

Wheat and rye bran

Bran is incredibly healthy. It's the residue left over from the threshing process, the grain hulls. It contains the most fiber, a substance essential for normal intestinal function. Due to its unique structure, bran not only swells in the stomach and makes you feel full, but also cleanses the intestines of all sorts of nasty things. It also contains a fair amount of potassium, iron, and magnesium, as well as some B vitamins. Experts generally recommend including bran in your diet—it's truly beneficial for a healthy diet.

An important point: bran should not be given to small children or people with intestinal diseases or peptic ulcers – after all, it is quite difficult to digest.

Corn

Many respected nutritionists believe that corn porridge is extremely beneficial for health. It lowers cholesterol, contains corn oil, which curbs appetite, and is loaded with vitamins. These include vitamin K, which is important for blood formation; vitamin E, which is beneficial for skin and hair; and vitamin D, which is essential for normal calcium metabolism. Corn porridge is also believed to boost the immune system, improve metabolism, and normalize bile secretion.

As for preparation, there's nothing complicated about it—it's just like any other porridge. Add it to boiling water or milk, simmer for a while, then steam. You can add honey or dried fruit later, but it tastes quite nice as is.

3. Physical activity

Physical activity helps keep all our body systems in good shape. Of course, this doesn't require professional training; regular morning exercises, if they become a habit, will be quite sufficient. Physical activity triggers the production of special cells, immunoglobulins, which protect us not only from viruses, bacteria, and fungi, but also from all kinds of allergies.

4. Get enough sleep

There's a saying among athletes: "It's better to undereat than to undersleep." And it's absolutely true. During sleep, the hormone melatonin is produced, which also protects our body, increasing antibody production and boosting the immune system's effectiveness. However, to be considered a full night's sleep, there are certain requirements. You need to sleep for at least eight hours in a completely calm environment. Turn off all electronics (TV, computer, etc.) an hour before bed.

5. Good nutrition

It's long been known that a balanced diet is not only the key to health but also to beauty. Eating plenty of vegetables, especially raw ones, brings certain benefits to our bodies. However, nutritionists highlight certain vegetables specifically for boosting immunity. These include garlic, red onions, and ginger—natural antiseptics; spinach—a storehouse of vitamins; beets—containing iron and fiber; asparagus and artichokes—vegetables high in B vitamins; sweet red peppers—rich in vitamin C; tomatoes—containing beta-carotene; and sweet potatoes—a source of vitamin E, a powerful antioxidant.

6. Good mood

Another piece of advice from experts says: a positive attitude is always the key to success. And it's true. You have the power to spend your free time with people you enjoy or to visit places and events that bring you joy. Heed the advice of experts and stay healthy.
