Humidity in a may be more noticeable in the summer, but it is a problem which can also persist all year round. Some of the most common signs of high humidity in a room include:

  • Increased heat: of course in warmer weather your body will feel hotter, but if humidity is too high you may find it almost impossible to cool down. If your room is too humid, you may find that you sweat more, struggle to sleep and feel more sticky (even after showering).
  • Increased mold: high humidity in a room will lead to a combination of heat and moisture, which combined is a breeding ground for bacteria. This will result in the appearance on mold on the walls, fabrics and almost anything porous. This high humidity and mold needs to be diminished. Breathing in these such bacteria infested spaces can lead to serious health problems.
  • Physical symptoms: the mold caused by high humidity in a room is usually accompanied by a fusty smell, something which can be hard to eradicate or even cover up. This bad smell can sometimes also transfer to your skin. If you find that even deodorant isn't quite covering up this humid musky smell , it could be a result of high humidity in your room which is clogging up your pores.
  • changes in your room: high humidity in a room can cause wood to swell and rot, something you might notice if your door sticks and doesn’t open easily. Additionally, the water in the air can cause oxidization of metal objects, forming rust.
  • The appearance of pools of water: if you see pools of water underneath your windows or thick droplets on your window panes, this is usually a sign of high humidity in a room.
  • Increased allergies.

High humidity in your room can be a problem, but so can low humidity. Low humidity in a room can make the air drier, causing your skin to lose moisture and become dry. In addition, it can increase the risk of contracting viruses or infections. According to home humidity levels chart, an ideal humidity level in a room should be 35-45%, although a little over or under shouldn't cause too many problems.

How to get humidity out of house without a dehumidifier

If you are experiencing some or all of the above problems, then you’re probably wondering how to get humidity out of house without a dehumidifier. The easiest way to get rid of humidity is to get a flat container with an open top and fill it with a kilogram of coarse salt. Place it in your room and it should absorbed a lot of the excess moisture in the air. We recommend using a wider and larger container as it will allow for more exposure. If you do decide to use a larger box, make sure to fill it with more salt.

You should notice a visible difference in your room’s humidity levels after roughly 2 days. But, why salt? Salt is one of the most absorbent natural products available, helping to combat moisture in the walls or to prevent mildew staining on clothing. Using salt is the most basic method when trying to make a homemade dehumidifier.

Once the salt has blackened or becomes wet, it means it has reached its maximum level of saturation and should be changed. But you also have the option of using other types of home remedies for humidity. Cat litter, for example, is another great option for reducing humidity in a room naturally. You can also opt for charcoal, although it may not be as effective.

How to reduce humidity in a room naturally

It's important to also know how you can prevent humidity at home. Thankfully, there are some simple tricks you can use in your room so that mold and/or stains don’t occur. If you have high humidity in your room, it's important to air it frequently, this is as simple as opening a window to let air circulate. Additional ways to prevent humidity in your home in include:

  • Using extractors or vents when cooking.
  • Using fans to move air around can also help prevent humidity, but nothing beats the use of an air conditioner. Buying an air conditioner or electric dehumidifier should be done if the homemade dehumidifier has proved unsuccessful.
  • Drying your clothes outside or on a terrace. This is important as the moisture from your clothes will otherwise enter your living space.
  • Check materials or objects which might be increasing the humidity in your room. Carpets can hold a lot of moisture, so if you have high humidity in your room, you may want to consider laminate (untreated wood can also absorb moisture) or linoleum for your floor. Plants also release water vapor and can contribute to humidity. Although they are visually lovely, you may want to replace them at some point to help get rid of humidity in your room.
  • Exposed pipes or leaky pipes are also big causes of humidity, so check to see if they are secure and whether or not they need insulated. Check your roof, window seals and anywhere else which might explain why moisture may be entering your room.

Natural dehumidifier: baking soda

If you have any baking soda in your home, you can also make a natural dehumidifier baking soda. Place some baking soda into a bowl and cover with a thin cloth.

Good suggestion.

Thanks for the advice. A/c is out of reach of common man. Moreover, a/c pollutes air which further resulted into global warming. Consumption of electricity by an a/c of one ton is equal to electricity consumes by nine fans. This being the fact, the use of salt to get rid of humidity is not only affordable but it is a contribution to the programme of minimization of global warming.
