A cold in February in Texas is a viral upper respiratory infection that peaks during late winter weather swings. Rhinoviruses and seasonal coronaviruses circulate more often when temperatures fluctuate and people gather indoors. In cities such as Houston, Dallas, and Austin, February often shifts from damp, cool mornings to warm afternoons. Those swings irritate nasal mucosa and dry airway linings. Dry tissue loses some of its barrier function, and viruses bind more easily to epithelial cells.
Texas also carries high winter pollen counts. Mountain cedar in Central Texas and elm in North Texas release allergens through February. Allergic rhinitis and viral colds share symptoms—nasal congestion, rhinorrhea, cough. Distinguishing them guides care.
Recognize the Clinical Pattern
Common cold symptoms follow a predictable inflammatory course. A scratchy throat and fatigue often appear first. Nasal congestion follows. Clear discharge may thicken after several days as neutrophils increase in nasal secretions. Low-grade fever may occur in children; adults rarely exceed 100.4°F. A dry cough can linger two to three weeks as airway nerves remain hypersensitive.
Influenza differs. Influenza causes abrupt fever, myalgia, and marked fatigue. COVID-19 may include anosmia or dysgeusia. Allergic rhinitis often causes itching and sneezing without fever. If you develop high fever, chest pain, shortness of breath, or confusion, seek medical evaluation. Those signs suggest complications such as pneumonia or bacterial sinusitis.
Rest and Hydrate With Purpose
Rest supports immune cell coordination. Sleep regulates cytokine signaling and antibody production. Aim for seven to nine hours. Short daytime naps reduce fatigue without disrupting nighttime sleep.
Hydration thins mucus. Water, oral rehydration solutions, and broths maintain mucociliary clearance. Warm fluids can reduce throat discomfort by increasing local blood flow. Alcohol dehydrates and disrupts sleep; avoid it during acute illness.
Indoor air in Texas homes becomes dry during heater use. Use a cool-mist humidifier to maintain relative humidity between 40% and 50%. That range supports mucosal function and may reduce viral stability in aerosols. Clean humidifier reservoirs daily to prevent mold growth.
Use Evidence-Based Medications
Over-the-counter drugs relieve symptoms but do not shorten viral replication. Select agents based on dominant symptoms.
-
Acetaminophen or ibuprofen reduce fever and relieve myalgia. Follow labeled dosing. Avoid ibuprofen if you have renal disease or active ulcers.
-
Pseudoephedrine reduces nasal congestion by vasoconstriction. It can increase heart rate and blood pressure; patients with hypertension should consult a clinician.
-
Oxymetazoline nasal spray shrinks nasal vessels quickly. Limit use to three days to avoid rebound congestion.
-
Guaifenesin increases respiratory tract fluid secretion and may thin sputum.
-
Dextromethorphan suppresses cough reflex centrally; it may reduce disruptive nighttime cough.
Antibiotics do not treat viral colds. Inappropriate antibiotic use drives resistance and exposes patients to adverse reactions. Zinc lozenges may reduce symptom duration when started within 24 hours, though results vary by formulation. Vitamin C does not treat active infection in most adults, but routine supplementation may slightly reduce duration in those under physical stress.
Soothe the Upper Airway
Local measures reduce mucosal irritation. Isotonic saline irrigation clears debris and allergens from the nasal cavity. Neti pots and squeeze bottles deliver saline mechanically. Use sterile or previously boiled water to prevent rare infections.
Honey reduces cough frequency in children over one year of age. It coats the pharynx and may alter cough receptor sensitivity. Avoid honey in infants due to botulism risk. Throat lozenges stimulate saliva and ease dryness.
Steam inhalation provides transient comfort but does not alter viral load. Avoid scalding injuries. Warm showers offer similar symptomatic relief with lower risk.
Adjust to Texas Climate and Allergen Load
February in Texas combines viral spread with airborne allergens. In Austin and San Antonio, mountain cedar pollen can reach high counts. If you experience itching eyes and repetitive sneezing, consider a non-sedating antihistamine such as cetirizine or loratadine. Intranasal corticosteroids treat allergic inflammation effectively; they require daily use for full effect.
Monitor local pollen and air quality indices. High particulate matter can aggravate cough. Limit outdoor exertion on poor air days. Change HVAC filters regularly. HEPA filtration can reduce indoor allergen burden.
Protect Others in Your Household
Respiratory viruses spread through droplets and contact. Wash hands with soap for at least 20 seconds. Alcohol-based sanitizers work when hands are not visibly soiled. Avoid sharing utensils, towels, and cups. Disinfect high-touch surfaces such as doorknobs and light switches.
If you live with older adults or individuals with chronic lung disease, wear a mask during close contact while symptomatic. Ventilate indoor spaces by opening windows when weather permits. Stay home from work or school during the febrile phase and when symptoms peak.
Maintain Nutrition and Physical Activity
Balanced nutrition supports immune competence. Consume protein sources such as eggs, legumes, poultry, or fish to provide amino acids for antibody synthesis. Include fruits and vegetables rich in carotenoids and flavonoids; they contribute to epithelial integrity and antioxidant defense.
Light movement aids circulation and mood. Short walks outdoors are acceptable if fever is absent and energy permits. Avoid intense training; heavy exertion can transiently suppress immune function.
Know When to Seek Care
Certain patterns signal complications. Seek medical evaluation if symptoms persist beyond 10 days without improvement, if facial pain intensifies, or if fever returns after initial recovery. Those signs may indicate acute bacterial sinusitis. Persistent productive cough with dyspnea may suggest bronchitis or pneumonia.
Children under three months with fever require prompt assessment. Adults with asthma or chronic obstructive pulmonary disease should monitor peak flow and adjust inhalers per action plan.
Prevent the Next Episode
Prevention depends on exposure control and vaccination. Annual influenza vaccination reduces severe disease risk. Updated COVID-19 vaccines lower hospitalization rates. Hand hygiene and surface cleaning reduce viral transmission during winter peaks.
Regular sleep, physical activity, and smoking cessation strengthen airway defenses. Smoking impairs ciliary function and increases susceptibility to infection.
February in Texas tests respiratory resilience. Viruses circulate. Pollen drifts. Indoor air dries. Direct, evidence-based care reduces discomfort and limits spread. Most colds resolve within seven to ten days. Care for symptoms. Monitor for warning signs. Let the immune system complete its work.
