The colder temperatures experienced in homes around the autumn and winter months can be tough to deal with, but they're not the only things people need to keep an eye on.
Less ventilation of the home and more time spent inside come with the potential for more air pollution, allergens and toxin build-up.
These sorts of particulate matter can come from a number of unlikely sources that households might not have considered.
If you're replacing a mattress, then it's important to give it time and space to air properly before putting it on your bed.
The Sliding Wardrobe Company explains: "Brand-new mattresses can release toxic gases into your bedroom via a process called 'off-gassing'.
"Your body heat can cause your mattress to release Volatile Organic Compounds (VOCs) - nasty chemicals, like formaldehyde - that could cause headaches, dizziness and other health risks."
A number of households can release VOCs, which may need to be kept in mind if people have certain underlying health conditions.
The Sliding Wardrobe Company shares: "Thankfully, many of them only produce small amounts of VOCs - but those with underlying health conditions, the very young, and the elderly should still be cautious.
"Air fresheners are a common culprit, as are paints and varnishes, along with some cleaning products and even deodorant.
"If you use these items in your home (and who doesn't!), ensure you have a good flow of fresh air throughout the house, or use an air purifier."
Mould can be found more easily in homes in colder months due to a lack of ventilation.
The Sliding Wardrobe Company says: "Small amounts of mould can cause allergic reactions or a skin rash, while elevated mould levels can lead to difficulties breathing, asthma attacks and even lung infections - especially if it's in your bedroom and you're breathing in the spores all night."
Mould can be kept at bay by increasing air flow in your home, tackling damp before it takes hold and wiping away mould when it first begins to appear.
While it may only affect a small number of people, scented candles can potentially release VCOs into the home.
Some of these types of candles are made with paraffin wax, which stems from petroleum, a by-product of gasoline production.
Research has shared that a small number of people have reported headache, shortness of breath and coughing after using scented candles, but there is no direct study to confirm a link between frequent scented candle use and health issues.
The Sliding Wardrobe Company says: "If you love a good candle, remember to only light them in a well-ventilated area of your home, don't keep them burning for too long and opt for safer beeswax or plant-based wax wherever possible."

This is more of a problem for studio flats or smaller homes, but nitrogen dioxide and fine particulate matter have been found in the homes of people who use gas hobs.
The Sliding Wardrobe Company adds: "If you have a gas hob, make sure you turn your extractor fan on while cooking - and keep it on for a few hours afterwards.
"You can also open windows to increase air flow, or invest in an air purifier."
