To stop overnight bedroom condensation, boost ventilation (open windows/doors briefly), reduce indoor moisture (use dehumidifiers, close bathroom/kitchen doors), and increase surface warmth by keeping heating low and steady, ensuring curtains/blinds aren't blocking airflow, and moving furniture from exterior walls to help air circulate and prevent damp spots.
As you surmise, the solution is to ventilate that room overnight, and that means cracking the windows open to 'vent' setting. You can demonstrate this by simply trying it. If the only bedroom ventilation you are currently relying on is 'trickle', then try a few nights with the windows open to at least 'vent' setting.
Sleeping in a damp room can lead to serious health issues, including respiratory problems, allergies, skin conditions, and a weakened immune system due to the presence of mould and excess moisture.
Should You Wipe Condensation Off Windows? Yes, wipe off any condensation on your windows with a soft microfibre cloth. It's one of the first things you should do. Not only does it protect your windows and sills, but it also helps maintain healthier indoor air quality by stopping mould from growing.
One way to reduce air moisture in your home is to use a dehumidifier. Dehumidifiers are electrical devices that help extract water from the air. Many people purchase dehumidifiers to eliminate musty odors and prevent mildew, mold and bacteria, but dehumidifiers can also be used to reduce condensation on windows.
Yes, a bowl of salt can help reduce condensation because salt naturally absorbs moisture from the air (a process called deliquescence), making the surrounding area drier and preventing water droplets from forming on windows or other surfaces. Placing a bowl of salt, especially rock salt, on a windowsill can help control humidity and reduce dampness, but you'll need to replace it as it clumps up with absorbed moisture.
Commercial anti-condensation sprays create a water-repellent coating on glass:
The Snake Plant is perfect for a bedroom as it absorbs water vapour at night, helping to tackle nighttime condensation on windows. Also, the plant will remove carbon dioxide from the air during the night and produce oxygen which is needed for a good night of sleep.
THE TEMPERATURE OF YOUR HOME
Cold air is more likely to deposit droplets of condensation around your home. Air is like a sponge, the warmer it is, and the more moisture it will hold. Heating one room to a high level and leaving other rooms cold makes condensation worse in unheated rooms.

What are symptoms and effects of mold exposure?
Bedrooms are often the first place condensation occurs. Why ? because throughout the night we create humidity in bedrooms from breathing and perspiration - and this is the time when the temperature of the rooms falls to its lowest point. These are perfect conditions for condensation to form.
Left unchecked, mould can impact your health, triggering allergies, nasal congestion and other respiratory symptoms. It can also cause wood to rot, which may compromise certain structures in your home. The good news is that using an air purifier for mould can keep mould from returning.
Baking soda, calcium chloride, and rock salt are all budget-friendly and readily available dehumidifying products. Put them in a bowl or bucket (or any container you see fit!), and you've got a natural dehumidifier that will start absorbing moisture from the air in your most humid rooms.
Signs of excessive HVAC condensation
Keep your home adequately heated
Try to keep your home suitably heated. It usually helps to have a low background temperature of at least 15 degrees in all rooms. By doing this you are less likely to have condensation dampness as the warm air holds more moisture than cold.
Yes, you should wipe condensation off your windows. In fact, if this happens regularly, it's a good idea to get into the habit of removing it every single day, recommends Stephen Hankinson, Heating Expert at Electric Radiators Direct.
How to tell if your house is poorly insulated
The ideal temperature is between 77 and 86 degrees Fahrenheit. During the summer months, temperatures are often higher than normal inside the home. Make an effort to keep temperatures inside the home lower during the summer months. Setting the thermostat to the low 70s makes it more difficult for mold to grow.
Yes, a bowl of salt can help reduce condensation because salt naturally absorbs moisture from the air (a process called deliquescence), making the surrounding area drier and preventing water droplets from forming on windows or other surfaces.

Increasing ventilation can draw out excess moisture. Ventilation fans that vent the air and moisture outside of your home help. Install and run ventilation fans in bathrooms and in the kitchen. Opening windows can also help with ventilation.

How to Stop Condensation on Windows
While vinegar is a great natural cleaner and can help remove mould spores, it won't stop the physics of condensation. If the surface is cold and the air is wet, water will form. It's better to fix the humidity level than to rely on temporary kitchen remedies.
