Heat actually does help a lot, cold walls will cause moisture in the air to condense on the walls and the mould needs that moisture to grow and spread. The best thing for combatting mould long term is keeping the house warm and humidity down, a dehumidifier will work wonders in the long term.
Temperature Mold spores typically need a temperature of 50--60°F (10--16°C) to survive. To prevent mold growth, you can try to keep your home's temperature above 60--65°F. Humidity Mold grows best in moist, humid environments. You can try to keep your home's humidity below 60%, ideally between 30--50%.
High Humidity: Cold air holds less moisture than warm air. If the indoor temperature is low, any moisture present (from cooking, bathing, or even breathing) can condense on cold surfaces, leading to higher humidity levels conducive to mold growth.
However, cold or freezing temperatures do not kill mold spores, rather it forces them to enter a dormant state in which they cease to grow until those more ideal conditions return as we discussed above. So, if you decide to freeze your bread with the hope of killing mold spores, don't count on it.
Your AC can control the temperature and humidity in your home, which can prevent mold growth. During the hot, humid summers, set your air conditioner between 68 and 72 degrees Fahrenheit. The relative humidity in your house should not exceed 50%.
Boiling water can kill mold outright (more on this in the next section), but you can't exactly boil your walls or carpet. However, you may be able to kill mold by heating it enough to dry it out. Most molds can be killed at temperatures of 140 to 160 degrees Fahrenheit, but the effect isn't immediate.
a dehumidifier, which extracts moisture from the air, can be bought or hired. wipe down surfaces affected by condensation regularly to prevent mould growth. mould can be removed by washing the surface with a disinfectant or a fungicidal wash. This must be used in accordance with the manufacturers' instructions.
Quick answer: The ideal house temperature is room temperature, which ranges from 68 to 78 degrees F, though this may vary from season to season.
Heating and Building Health
If a building is not adequately heated during the winter months, it can cause problems for the residents in terms of comfort, but it can also lead to damage to building fabric and exacerbate issues with damp and mould.
Mold hates light. Other than moisture there's nothing mold loves more than dark places. An easy prevention against mold growth is opening your blinds and shades. If it's warm enough out, open the windows.
In general, it's recommended to set your thermostat to 55 degrees Fahrenheit or higher. This may seem high compared to the freezing point of 32 degrees Fahrenheit, but it'll help keep the interior of the floor and wall cavities – where your plumbing is often located – safely above freezing temperatures.
Mould thrives in damp areas such as windows, where there is dust, dirt or organic material, that's why the number one way to reduce mould is to open your windows regularly. By opening the windows at least once a day, this allows the mould spores to escape and lets patches of moisture dry out.
Keeping the air conditioner set at 78 degrees or lower prevents mold buildup in the summer. Even when leaving for a few days or vacation, don't set it above 80. A higher setting won't provide enough dehumidification from the cooling process to prevent spores from growing.
The only effective way to permanently get rid of mould problems is by reducing the build-up of moisture in your home. This can only be achieved through better ventilation.
During heat waves, experts, including utility companies, recommend keeping your thermostat no more than 20 degrees cooler than the outdoor temperature. For instance, if it's 100 degrees outside, aim to set your thermostat to at least 80 degrees.
65 Degrees is (Nearly) the Perfect Temp
Keeping the house balmy can cost a fortune in power bills. Instead, turn down that thermostat to somewhere between 60 degrees and 70 degrees F. For most people, 60 is a chilly sweater-friendly temperature, while going over 70 can get a little toasty.
For most people, 75 degrees is too hot to sleep, per the National Sleep Foundation. But the new study found that in people 65 and up, sleep efficiency only started to decrease when temperatures were above 77 degrees.
The common method to reduce the risk of mold in winter is the interaction between heating and ventilation. Heating ensures that warmer air can better absorb and retain moisture. At the same time, surfaces and walls warm up, reducing the temperature difference and allowing less water to condense there.
Mold is an obvious health risk in any home, but investing in an air purifier can help limit your exposure. The best among them will ideally offer HEPA-level filtration, with this level of filtration being able to trap up to 99.97% of airborne particles down to 0.3 microns in diameter.
Can lack of insulation in your house cause mold? As a matter of fact, yes. This microscopic fungus tends to grow in warm, wet environments—and its contamination is a messy issue for modern homeowners. Ergo, preventative measures are essential to minimize and contain any potential growth problems.
Cold rooms especially are often rarely visited by homeowners, but contain a damp, dark and cold environment that allow mold to flourish. Many people only consider mold growth following a water leak or flooding, but mold can grow anywhere, anytime in areas of your home that are damp and cold.
Many fungi grow well at temperatures between 60 and 80 degrees Fahrenheit, which are also ideal temperatures for human comfort. In addition, as mentioned above, temperature gradients often produce the moisture needed for mold growth.
