Here are some foods that can help along with many other helpful tips for those wondering about how to improve the immune system.
Handwashing helps protect against viruses and bacterial infections
Start with good defense. Do not give germs an opportunity to cause harm. Proper handwashing is a simple and effective way to avoid the spread of infectious conditions and respiratory ailments like coronavirus, flu, and colds. Some bugs are easily transmissible from one person to another once we come into close proximity with one another. It’s also easy to transfer these germs from your hands to your face with a simple touch. This can make you get sick. Many doctors and country leaders have displayed the proper hand washing techniques on TVs all around the world with the coronavirus pandemic. Scrub all surfaces of your hands: front, back, in between fingers, and areas under the fingernails. Antibacterial soap and hand sanitizer may give additional protection against germs you cannot otherwise see.
Importance of Regular Exercise
Engaging in regular exercise can work as an immune system booster. Studies have shown that even one session of mild to moderate exercise can help increase the effectiveness of vaccines in people who have a weakened or compromised immune system. Regular exercise is also known to increase the production of T cells, which are a kind of white blood cells in the body that are responsible for fighting off infection. At the same time, exercise also lowers the levels of inflammatory cytokines in the body that are responsible for aging and are also believed to play a role in causing cardiovascular disease, Alzheimer’s disease, osteoporosis, and type 2 diabetes.
The best and one of the most straightforward exercise you can practice for improving our immunity is walking or brisk walking. Walking has been shown to protect you during the flu and cold season. A study conducted on over 1,000 participants, both men and women, discovered that those participants who walked for at least 20 minutes in a day, for at least five days a week, had 43 percent lesser sick days as compared to those who only exercised once in a week or less. The study also found that if these participants did fall ill, then it was for a shorter duration, and the symptoms they experienced were also milder.[3, 4]
So all those who are wondering how to improve the immune system should think about walking for at least 15 minutes a day. Exercise has numerous health benefits and can protect you against cardiovascular disease, osteoporosis, and even certain forms of cancer. Exercise and physical activity is also an immune booster. Walking can be peaceful and one of the easiest ways to work out. You can also try yoga, gardening, biking, or swimming.
Getting adequate sleep
A good night’s sleep is a critical requirement for boosting the immune system. In fact, poor quality of sleep or insufficient sleep is associated with a higher likelihood of sickness. Researchers have even found that proper sleep helps boost the T cells in the body and helps them fight off infection more aggressively.
Several studies have reported that a good night’s sleep improves the primary cells of the immune system known as T cells.
Adults ideally need to get a minimum of six to seven hours of sleep each night for their overall wellbeing and health. However, people often underestimate the importance of sleep and cut back on sleep in order to complete their work or for a night out with their friends. Prolonged lack of sleep can have many adverse effects on the body, including creating a fight or flight state. When the body is perpetually under a fight or flight state, there is an increase in stress hormones and an increased production of adrenaline. All these factors have been found to be responsible for many chronic diseases.[6, 7]. Adequate hours of sleep not only acts as an immune system booster but sleeping when you are unwell, allows the immune system to better fight against the disease, making you sick.
Following essential sleep hygiene tips such as avoiding screen time just before bedtime, sleeping in a completely dark room, using an eye mask for sleeping, and sticking to the same bedtime every night, are necessary for ensuring a good night’s sleep to boost your immune system.
Restrict the intake of sugars
Several studies have discovered that an increased intake of added sugars along with refined carbohydrates contributes to obesity, being overweight, which, in turn, increases the risk of falling sick.[9, 10]
A study carried out on 1,000 participants found that the participants who had obesity and were administered the influenza vaccine were twice as likely to catch the flu as compared to those who were not obese and received the same vaccine.
Restricting the intake of added sugars is essential to boosting your immune system. In fact, anyone who wants to know how to boost the immune system must try to limit their sugar consumption to less than five percent of their total daily calories. This means that for an individual on a 2,000 calorie diet, they should not be having more than two tablespoons of 25 grams of sugar in a day.
Immune system boosting foods
Immune System Booster Foods
While following the above steps can also boost your immune system, there are many different types of foods also that can help you improve your immunity. Here are some immune system booster foods that you should include in your diet:
• Citrus Fruits: Citrus fruits are a powerhouse of vitamin C. Vitamin C is known to be a natural immune booster as it increased the production of white blood cells, which are vital in fighting against infections and diseases.[12, 13] Some popular citrus fruits you can think of having are oranges, tangerines, lemons, clementines, grapefruit, and limes.
• Broccoli: Broccoli is a powerhouse of many essential nutrients, including vitamins and minerals that help the body fight against infections. Broccoli is loaded in vitamins A, E, and C, along with a healthy dose of fiber and antioxidants.

• Garlic: Garlic is a common ingredient we add to many of our dishes. It not only adds a dash of flavor to our meals, but it is also an immune system booster. Garlic can help in the management of high blood pressure and even slow down the hardening of the arteries.

Boost immunity by reducing stress
Stress & anxiety is an enemy of your immune system.
Chronic stress is bad for your immune system and increases the risk of various types of illnesses. It increases the level of hormones known as catecholamines. Being stressed out contributes to elevated levels of suppressor T cells, which suppress the immune system. If this branch of the immune system is impaired, you’re more prone to viral illnesses such as respiratory ailments like colds, flu, and the novel coronavirus disease. Stress contributes to the release of histamine, a molecule involved in allergies. You can combat stress and anxiety with plans like deep breathing, meditation, exercise, and comfort.
Get your vitamins
Take multivitamins if needed.
Taking a daily multivitamin can help ensure you are meeting at least your minimum everyday requirement for specific nutrients. Vitamins which are critical for immune function include vitamins A, C, D, and E. Zinc, selenium, and magnesium are minerals your immune system needs to function at its best. These minerals can also be critical for the function of many enzyme reactions in the body. Your immune system and body can not function at their best without the fundamental building blocks they need to operate correctly.
No junk food
Say no to junk food diet. Processed foods such as fast foods and snack foods contain empty calories that don’t supply your body with vitamins, nutrients, or fiber.

Ditch processed foods in favor of vegetables, fruit, healthy fats, lean meat, and whole grains to provide your body and immune system everything they need to function at their very best. Boost your dietary habits to support your wellbeing.
Herb and supplement immune boosters
Some research has indicated that compounds in supplements and herbs can enhance immunity.

Speak with your health expert before adding supplements and herbs to your regimen. They may produce side effects, particularly when combined with other herbs, supplements, or medications. Probiotics are beneficial strains of bacteria which have also been described as immune boosters. Start looking for supplements with lactobacillus and bifidobacterium. Probiotics can also help enhance digestive health.
No smoking or alcohol
Alcohol suppresses immunity: Alcohol depresses the immune system, so it is better to consume it in moderation or not at all. Men and women may have the ability to consume up to 2 and 1 alcoholic beverages daily, respectively. There are many factors, including general health status, risk factors for illness, and any medicines you might be taking. Consult with your doctor if it is okay for you to have an occasional alcoholic beverage.

Many natural remedies are available that can help you quit smoking.
Social & lifestyle changes

In one study, those with the most important social relationships were most likely to live longer than people who have poor social relations. There are lots of approaches to develop and strengthen social ties. Pick up the phone and call friends frequently. Make plans to get together in person. Volunteer for a cause you believe in. Join a class or keep up with old friends and make new ones to fortify and expand your social circle.
Positive thinking to Boost Immune System: Expect great things, and your immune system will follow.

Practice gratitude and consider at least three items that you’re grateful for every single day. Imagine the ideal outcome for scenarios, even difficult ones. You may not always have the ability to control events around you, but you could control your reaction to them. Respond with a positive attitude to increase the odds of the very best outcome and to strengthen your immunity.
Laughter is the best medicine: Can laughter actually boost your immune system? The results of several studies suggest it could.

While more research is required to establish a conclusive link between laughter and enhanced immunity, go ahead and have a great chuckle. Belly laughs feel great. They can not hurt, and they may help improve your immune system and lessen the probability of illness.
