February is the month of love, but if you ever find yourself feeling lonely, remember you are never truly alone. Your body is home to approximately 38 trillion bacteria, tirelessly working to support you in your daily pursuits. These microscopic companions play essential roles in digestion, nutrient production, and immune defense, and hopefully, they will also be receiving a Valentine’s Day present as a reward for all their hard work.
However, as the seasons change, our bodies and the delicate balance of our microbiome can become stressed and fatigued. This creates an opportunity for stronger pathogens to take hold, potentially leaving us feeling under the weather, struggling to breathe, and wishing we had taken better care of ourselves.
In the spirit of caring for one another, this post takes a closer look at the most common illnesses and causes of sickness in February and explores how supplements can help support overall health during this time.

Common Illnesses in February
February, and winter months in general, often sees a surge in seasonal illnesses. As the colder weather keeps us indoors more often, closer contact to others for prolonged periods of time is inevitable, which creates perfect conditions for viruses to spread. As a result, colds, flu, and respiratory infections become far more common this time of year.
By understanding what causes these illnesses and recognizing their symptoms, we can take proactive steps to support our immune systems and stay resilient through the toughest winter days.
Seasonal Flu and Its Symptoms
The flu spreads easily in colder months, thriving in low humidity and close-contact indoor environments. Additionally, influenza viruses mutate frequently, allowing new strains to circulate each season, which is why annual flu outbreaks are so common. Factors like cold temperatures, reduced sunlight exposure, and weakened immune defenses contribute to the increased risk during winter, and, as you will see, are common causes for many illnesses experienced during colder months.
Since flu symptoms can escalate quickly, early detection is key to managing the illness effectively. Flu vaccination remains the best preventive measure, helping the immune system function by recognizing and fighting off evolving strains. Additionally, supporting the body with proper rest, hydration, and immune-boosting nutrients, such as vitamin C supplements and zinc supplements, can also aid recovery.
Supplements can also play an important role in ensuring a healthy winter season. For instance, vitamin D supplementation (1,000–4,000 IU daily) has been shown to reduce respiratory infections by 11%, making it especially beneficial in winter months when sunlight exposure is limited. Elderberry extract, studied in laboratory settings, has also demonstrated potential in shortening flu duration, with higher doses taken over 10 days leading to faster symptom relief.
Common Cold and Respiratory Issues
The common cold is caused by a variety of different viruses, with rhinoviruses being the most common. These viruses spread easily through respiratory droplets and contaminated surfaces, thriving in cooler temperatures and dry indoor environments. While generally milder than the flu, untreated colds can sometimes lead to complications like sinus infections and even pneumonia. To help your body fight viruses, consider incorporating vitamin C supplements into your daily routine, as they can bolster immune system function and reduce the severity of symptoms.
Colder months create ideal conditions for respiratory illnesses to spread. A combination of low humidity and cold temperatures allows viruses to survive longer, while reduced sunlight exposure can lead to lower vitamin D levels, which may weaken the immune system. Spending more time indoors in close contact with others also increases the risk of transmission, making it crucial to maintain a well-rounded supplementation plan that includes essential nutrients like zinc and vitamin D.
Preventing the spread of these common illnesses comes down to good hygiene habits, such as regular handwashing and avoiding close contact with those showing symptoms. Keeping indoor humidity at a comfortable level can also help reduce virus survival, as water molecules can interfere with viral particles, reducing their stability and effectiveness in staying infectious.
Should you contact a cold, warm liquids, like herbal teas or broths, are your best friends. They provide relief from nasal congestion and help soothe throat irritation. Additionally, regular vitamin C supplementation can cut the risk of upper respiratory infections by 33%, with the most noticeable effects in physiologically stressed individuals. Lastly, Daily vitamin D supplementation (1,000–4,000 IU) has also been shown to help reduce respiratory infections, making it a useful addition to winter wellness routines.
Sore Throat and Cough Problems
Sore throats are most commonly caused by viral infections, including the common cold, flu, mononucleosis, and COVID-19. These infections can lead to pain, difficulty swallowing, and persistent coughing, making it hard to focus at work, attend school, or engage in daily social activities. While most sore throats are mild and resolve on their own, symptoms can be uncomfortable and disruptive.
For relief, home remedies like warm saltwater gargles and honey can help soothe irritation, while over-the-counter options such as menthol lozenges or throat sprays provide temporary comfort by numbing the affected area. However, these treatments do not address the underlying infection. Staying hydrated, using a humidifier, and avoiding irritants like smoke and dry air can also help ease symptoms
In some cases, a sore throat accompanied by a chronic cough may signal a more serious condition, such as acid reflux (GERD), allergies, or bacterial infections like strep throat. If symptoms persist for more than 10 days, worsen over time, or are accompanied by fever, difficulty breathing, or swollen lymph nodes, it’s important to seek medical attention. A healthcare professional can determine whether further treatment, such as antibiotics or other targeted therapies, is necessary.
Reasons for Sickness in February
February is a popular month for seasonal illness, influenced by environmental, behavioral, and physiological factors. Sudden shifts between cold outdoor air and heated indoor spaces can strain the immune system function, making it harder to fight infections and protect our hard-working body cells from pathogens.
Shorter days and reduced sunlight can also lead to lethargy and mild depression, further weakening the body’s defenses. Simple habits like spending time outdoors during daylight hours and staying active can help counter these effects and support immunity, ensuring that your white blood cells have the energy to fight foreign invaders, pledge their undying love to your well-being, and be your forever valentine. Additionally, incorporating vitamin C supplements (or from food sources) into your diet can provide significant health benefits during this time.
Post-holiday lifestyle patterns also play a role, as late nights, heavy foods, and seasonal stress take a toll on immune health. Replenishing essential nutrients with leafy greens, citrus fruits, and fortified cereals can help restore key vitamins like C and D, the latter of which nearly 40% of Americans lack during winter.
At the same time, more time spent indoors increases exposure to germs, making frequent handwashing, surface disinfection, and mask use in high-risk settings smart precautions. Prioritizing quality sleep is also key, as insufficient rest weakens the immune system, making the body more vulnerable to illness.
Supplements for Illness Prevention
Supplements can be a valuable tool for boosting immune support, particularly during cold and flu season. By addressing nutritional gaps, they work alongside the body’s natural defense systems to promote overall wellness. However, they are most effective when paired with a balanced diet and an active lifestyle.
As with any health regimen, consulting a healthcare provider before using supplements is essential. This ensures they are used safely and appropriately, with recommendations tailored to individual needs while also considering any potential interactions with medications or existing health conditions.
Here’s a brief overview of beneficial supplements:
Vitamin C for Cold Symptoms: Vitamin C is commonly praised for its effect on cold symptoms. It’s rich in foods such as oranges, strawberries and bell peppers. Research shows that regular vitamin C consumption can shorten the length of colds by an average of 9.4%. Though dietary sources are best, supplements with 500–1,000 milligrams per day can provide extra immune support in times of illness.
Vitamin D for Immune Support: Vitamin D is known to enhance immune function, including by reducing inflammation. Since winter sunlight is limited and can cause deficiencies, this vitamin is often best obtained through dietary sources such as salmon or fortified milk. Supplements of at least 600–800 IU daily are protective, especially among individuals with limited sun exposure.
Zinc for Faster Recovery: Zinc helps maintain optimal immune cell activity and accelerates recovery. Oysters and pumpkin seeds are excellent food sources. Lozenges are especially useful as a supplement if taken within 24 hours of the first symptoms appearing. Thoughtful dosing avoids negative side effects such as nausea.
Elderberry for Boosting Immunity: Elderberry is a great natural choice for supporting immune response. Research continues to showcase its effectiveness in preventing upper respiratory infections, including colds and flu. Commercial syrups or capsules high in antioxidants are best, especially during cold and flu season.
Omega-3 for Respiratory Health: Omega-3 fatty acids, like DHA or EPA, reduce inflammation and promote lung health. Fatty fish such as mackerel or fish oil supplements are some of the best sources. These nutrients can provide relief from respiratory distress, particularly for individuals on restrictive diets.
Traditional Remedies for Winter Illnesses
Traditional remedies have been used for centuries as a complementary approach to modern medicine, particularly during times of increased winter illness. These remedies are beautiful expressions of cultural heritage and ancestral, experiential wisdom passed down generations to help alleviate the symptoms of cough, sore throat and congestion.
Learning about traditional remedy options can bring you, and your microbe friends, added comfort and support in addition to conventional treatments.
Herbal teas for cough and sore throat: Herbal teas, like chamomile and peppermint, have long been praised for their calming qualities, which can relieve soreness associated with throat irritation. Warm liquids are soothing and will help you to feel more comfortable, relaxed, and hydrated. Homemade blends, such as ginger tea with a bit of honey, can help stop coughs and cough irritation while promoting overall wellness. Chamomile is most relaxing, and peppermint provides a refreshing, cooling effect that opens up and loosens congestion.
Honey and lemon for throat relief: A combination of honey and lemon offers soothing relief for sore throats. Honey’s natural antibacterial properties, paired with lemon’s vitamin C, make for a natural remedy that’s as soothing as it is effective. Warm honey-lemon water, made with raw honey, soothes irritated mucous membranes and promotes healing.
Steam inhalation for congestion: Steam inhalation is a simple technique to help clear nasal congestion. Safe practices involve using a bowl of warm water and a towel to capture steam. Adding essential oils, like eucalyptus, boost its decongestant powers. Keeping up with fluid intake is an important partner to this therapy, helping mucus stay thin and easier to cough out.
Additional Tips for Staying Healthy
Staying healthy requires more than just supplements. A balanced approach that includes nutrition, hydration, exercise, and stress management helps strengthen the immune system.
A diet rich in fruits, vegetables, whole grains, and lean proteins provides essential nutrients, with foods like oranges and bell peppers offering vitamin C, which may shorten colds by up to 8%. Whole grains sustain energy, lean proteins aid in tissue repair, and reducing processed foods and added sugars helps lower inflammation, supporting immune function.
Staying hydrated with plenty of water and herbal teas like green tea, which contains 50–100 mg of catechins, also supports immune health, while dehydration can worsen symptoms like fatigue and dry mouth.
Regular physical activity boosts circulation, helping immune cells move efficiently. Activities like brisk walking or yoga can also lower stress, which is known to suppress immune function. Quality sleep is equally essential, as it aids in immune recovery, and establishing a bedtime routine improves sleep quality. Managing stress through techniques like meditation further supports both mental and physical health. By maintaining these habits, the immune system stays resilient, improving overall well-being and recovery from illness.
