Low temperatures and dry air during winter pose health risks. Ideally, indoor humidity should be maintained at 40-60%. Symptoms such as psoriasis, itching, nosebleeds, and dry eyes may occur when it falls below this range. Here are three ways to maintain a comfortable winter environment without a humidifier.
1. Grow Plants
Growing plants with broad or abundant leaves can help maintain optimal indoor humidity. Through transpiration, water escapes from the undersides of plant leaves, creating a natural humidifying effect. Plants can also regulate indoor temperatures.
The drier the air, the more active this function becomes, meaning plants are especially effective in humidifying dry indoor environments. Filling 2-5% of a room’s area with plants can increase indoor humidity by 5-10%, and 3-10% coverage can raise it by 20-30%.
Among various plants, Adiantum is particularly recommended. This fern-like plant is an excellent indicator of optimal indoor humidity. If its leaves and stems remain healthy and do not dry out, it suggests that indoor humidity levels are appropriate.
2. Use Fruit Peels
Another method is to use fruit peels with high moisture content. Placing dried lemon or mandarin peels on a table or desk and spraying them with water occasionally can increase humidity in the surrounding area. The refreshing scent also helps reduce fatigue.
Another effective method is to fill a cup or bowl with water and add a drop of essential oil. This not only improves humidity but also provides the health benefits of aromatherapy.
Lavender can help relieve stress in the workplace, while cinnamon or peppermint is beneficial for bronchitis. Consider juniper berry, geranium, eucalyptus, or sweet orange oil for skin conditions.
3. Drink Water Frequently and Use Saline Solution
If maintaining indoor humidity is challenging, drinking water frequently to keep your body hydrated or rinsing your nasal passages with saline solution can be helpful.
Fill a disposable syringe with about 30cc of lukewarm saline solution to perform a saline nasal rinse. Gently insert the solution into one nostril, allowing it to flow through the other.
To be effective, hold your breath while keeping your mouth open when inserting the saline. A light “ah” sound will naturally stop your breath and open your mouth.
However, be cautious not to force the saline too hard, as this can cause it to flow back into the ear, potentially leading to an ear infection.
