Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Individuals sneezing or coughing due to a cold or flu are contagious regardless of their perceived stage of illness.

✕Not SupportedIf already experiencing a bacterial or viral infection, cyclic hyperventilation breathing or deliberate cold exposure may be detrimental.

◐Partially SupportedOral breathing is associated with a higher prevalence of allergies and increased likelihood of illness.

◐Partially SupportedNasal passages contain physical barriers like nasal hairs that defend against incoming viruses, fungi, and bacteria.

◐Partially SupportedFever is an adaptive immune response that helps the body kill pathogens by increasing temperature.

✓Well SupportedDry indoor air in winter can dry out nasal passages and increase susceptibility to infections.

✓Well SupportedBreathing through the nose is the optimal method for respiration during neutral or low-intensity activity.

◐Partially SupportedThe structure within the human nose acts as a primary defense site for destroying potentially incoming viruses.

◐Partially SupportedPhysical barriers like nasal hairs and skin defend against viral entry.

✓Well SupportedNasal breathing warms and humidifies air, which may reduce viral susceptibility by maintaining heat in the respiratory tract.

◐Partially SupportedIndividuals are more susceptible to colds and flus in winter months because these pathogens are more prevalent.

◐Partially SupportedBreathing through the nose whenever possible is healthier than mouth breathing.

◐Partially SupportedDeliberate breathing practices and deliberate cold exposure can help prevent infections.

◐Partially SupportedTaking a hot shower, bath, or sauna after getting chilled is recommended to heat back up.

◐Partially SupportedHighly elevated body temperatures can damage the brain and body.

◐Partially SupportedWhen exercising in cold weather, try to breathe through your nose unless mouth breathing is necessary.

◐Partially SupportedExercising outdoors during winter months is important for health, provided it is done safely.

◐Partially SupportedIn winter months, days are shorter and nights are longer, especially when living far from the equator.

◐Partially SupportedPeople spend more time indoors during winter months due to shorter days and colder temperatures.

◐Partially SupportedThe body constantly combats viral, fungal, and bacterial infections through physical, neurochemical, hormonal, and immune mechanisms.

◐Partially SupportedNasal hairs, mucus, and the nasal microbiome collectively protect against incoming infections.

◐Partially SupportedThere is a relationship between core body temperature and susceptibility to cold and flu.

◐Partially SupportedRunning with nasal passages drying out does not increase susceptibility to colds and flus if no one else is around.

◐Partially SupportedSleep deprivation can worsen cold and flu symptoms.

◐Partially SupportedThe proximity and connection of nasal passages to the brain highlight the importance of nasal defenses against infections.

◐Partially SupportedRehydrating nasal or oral passages via a hot shower, steam room, or humidifier after outdoor exercise in winter can reduce susceptibility to colds and flus.

✕Not SupportedBlunting a fever with medication may allow a cold or virus to proliferate more readily.
