A research by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) shows that the ideal indoor humidity level for health is about 40%-60%.
Dry environment with humidity level below 40% will not only result in dry skin and hair, but also make viruses and bacteria more active, therefore increase the likelihood of being infected by colds and other respiratory illnesses. Studies have shown that the survival rate of influenza virus can be as high as 70% in an environment of about 20% humidity level. The effectiveness of mucosal clearance and the body's resistance function to airborne viruses, will be greatly reduced when the relative humidity is less than 40%.
You can use a hygrometer to measure the indoor humidity. You can use a humidifier to adjust the humidity of your room. There are different sizes of humidifiers and they each have a different humidifier rating, as well as square footage usually covered. Cool mist/evaporative humidifiers are generally cheaper than warm mist and ultrasonic ones. Good brands such as Dyson, Keecoon【large-scale capacity】, Panasonic, etc.
Maintain low indoor humidity, ideally between 30-50% relative humidity
The relative humidity (RH) in a kitchen can be measured by using a humidity gauge. A maximum indoor relative humidity of 55% RH may be acceptable, but a 50% RH better is better.
Because it's about relative humidity, not absolutehumidity. Air can carry a certain amount of moisture dependent on which temperature it is, with warmer air being able to carry more before condensation occurs. If you have two volumes of air, both containing the same amount of water, then the warm volume will be a lower relative humidity than the cold volume.

Wood cabinets are generally not suitable for rooms with high humidity. High humidity can cause the wood to warp, swell, or rot over time. It is recommended to choose cabinets made from materials like laminates or thermofoil, which are more resistant to moisture. If you prefer the look of wood cabinets, you can consider using sealed or treated wood that is more moisture-resistant.
You can you hang an indoor ceiling fan outside under a covered porch. As long as the outside conditions remain close to what the conditions inside the home are. This means as long as it is protected from the weather e.g. rain, direct sunlight, no high humidity.

The usual design humidity for an indoor swimming pool is 50% RH when unoccupied and 60% RH when occupied Peter Fenton. Consulatant. Indoor-Pool-Design.com
75 degrees F OK that's fine for temperature but what is the ideal room humidity percentage? Actually, most building codes only require you at keep the temperature at 68 degrees, which is ideal. The ideal room humidity percentage is usually around 50% ASHRAE Standards: 68-74F @40-60% relative humidity in the Winter 73-79F @40-60% relative humidity in the Summer

If you have de-humidifiers then just take out the plug.
You can always grow them indoor with suitable humidity and distilled water.

There is a concept called saturated water vapor. In short, if the room temperature is high, there will be a lot of water vapor in the air, and vice versa. That is to say, in a natural state, indoor humidity tends to be high in summer and low in winter. But even in summer there is a possibility of low indoor humidity because air conditioning has the function of converting heat into moisture and expelling it. Therefore, even in an air-conditioned environment, we have to consciously control the appropriate humidity.Using humidifiers to adjust the humidity indoor.
