Indoor Micro-Ecological Architecture: Bedroom Air Quality Management, Green Lighting Design, and Bathroom Disease Prevention Engineering Details
Assuming an 8-hour sleep period, a person breathes approximately 7,000 times, passing through about 2,400 liters of air. Poor air quality in the bedroom, containing various chemical pollutants or pathogenic microorganisms such as fungi and viruses, can severely damage health. To maintain fresh air in the bedroom, it's important to note the following: Avoid placing too many plants in the bedroom. At night, when there is insufficient light, green plants absorb oxygen and release carbon dioxide. The more plants in the bedroom, coupled with closed doors and windows, the more likely a person is to be in an oxygen-deficient environment, causing persistent fatigue. Use chemical cleaning agents with caution in the bedroom; furniture and floor cleaners, air fresheners, etc., contain irritating substances that can affect sleep quality. When using a vacuum cleaner, check the dust bag for damage; use negative ion generators and ultraviolet sterilizers with caution; household air filters have low ventilation efficiency and should also be used with caution.
From a health perspective, the trend of enclosing balconies among urban residents does more harm than good. Firstly, enclosing a balcony affects air circulation, increasing indoor air pollution and the concentration of harmful gases, leading to a weakened immune system. Secondly, it isolates people from nature. Most importantly, enclosing a balcony reduces direct sunlight, resulting in insufficient ultraviolet radiation indoors, which is detrimental to fungal growth and increases the risk of colds and pneumonia; it also hinders vitamin D synthesis in the skin, increasing the probability of osteoporosis in the elderly and rickets in infants and young children.
In interior design, simplicity should be the guiding principle. Many homes use a variety of colors in their lighting, which can damage eyesight and interfere with the central nervous system. Creating a "green lighting environment" requires consideration of: 1. Functional requirements: Choose lighting methods according to the space, such as a warm bedroom and a bright study, avoiding flickering light. 2. Coordination requirements: Lighting fixtures should coordinate with furniture style, space size, and color. 3. Scientific and reasonable: Avoid glare, distribute light sources reasonably, and avoid direct light into the eyes.
The construction details of the bathroom are also related to men's health. An ideal bathroom should be 58 square meters, and ventilation is crucial. A bathroom with natural light is best, while a bathroom without natural light requires a high-powered exhaust fan. The layout should be divided into dry and non-dry areas. Soft lighting and light-colored tiles should be used in the bathroom to make it visually spacious and bright. The drainage system must be airtight: (1) The water seal height of the floor drain should reach 50 mm to prevent odors from the drain pipe from spreading in. (2) The floor drain should be about 10 mm below the ground, and the flow rate should not be too small. (3) The area around the floor drain should not be rough to prevent hair from getting caught and fungi from growing. (4) The opening of the floor drain should be between 68 mm.
Tiles are key to waterproofing. Walls should be fully covered with waterproof, mold-resistant tiles; floors should use textured, non-slip tiles; a waterproof layer should be laid underneath the surface, and the waterproof layer should extend upwards at least 25-30 cm above the ground where it meets the wall. Regarding toilets, surveys have found that 32% of toilets contain Shigella bacteria, and Shigella sonnei can survive for 17 days. Do not use cloth toilet seat covers in winter, as they easily absorb excrement. Wipe the toilet with diluted disinfectant every one or two days. When cleaning, first lift the toilet seat, spray toilet cleaner for a few minutes, then thoroughly scrub the inner rim and deep into the drain opening with a fine-headed brush.
Regarding the use of fluorescent lamps, the invention of electric lights has impacted human metabolism. To reduce "light stress," scientists suggest adding lampshades to desk lamps and using a mix of fluorescent and incandescent bulbs. Rooms larger than 12 square meters are suitable for 20-30 watt fluorescent lamps; rooms smaller than 10 square meters are suitable for incandescent bulbs with white lampshades. Fluorescent lamps are not recommended for desk lamps because their strong contrast can easily cause eye fatigue. Incandescent bulbs are better for desk lamps as they provide more even light. The study desk should be placed to the right of the light source so that the light comes from the left front to protect eyesight.
