Not heating your house in cold weather leads to serious health problems like respiratory and heart issues, mold growth, and damage to the building, particularly from frozen pipes that can burst, causing water damage and costly repairs, making it essential to maintain some level of warmth.
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.
Cold homes are also associated with negative health outcomes more widely, including heightened risk of heart attacks, impairment in children's lung and brain development and respiratory problems, which can be exacerbated by damp and mould.
Condensation, damp and mould
Colder homes often have more problems with damp and mould. Damp can also cause deterioration of the building, making it harder and more expensive to repair.
It depends on the extremes of your temperatures. If it doesn't get very, very cold or very, very hot where you are, you'll probably be okay. But human haven't lived without AC or heat for a long time, and keep in mind lots of people die every year because of extreme temperatures.
Cold homes contribute to excess winter mortality and morbidity. Most of the health burden can be attributed to both respiratory and cardiovascular disease, especially for older people.
How Long Can My House Stay Warm Without Heat? Most homes begin losing heat within a few hours, and depending on outside temperatures, can drop to unsafe levels within 12 to 24 hours.
How cold is too cold? Below 13° - If your home is this cold, it may increase your blood pressure and risk of cardiovascular disease. 14-15° - If your home is this cold, you may be diminishing your resistance to respiratory diseases. 18° - This is the recommended night time bedroom temperature.
Water pipes will begin to freeze once temperatures have reached zero degrees Celsius or below, but to freeze, they will need to be exposed to those temperatures for at least a total of six consecutive hours.

Signs of an Unhealthy Temperature
The main sign that your thermostat needs adjusting is that you and your family are too cold. Even though the furnace is running, you find yourself shivering or needing extra layers. If you're too cold in your own home, turn up the heat until you're comfortable.
In light of this, we can reveal the most common problems to expect if a home is not adequately heated during the colder months. From damp, mould, frozen pipes and – in some of the worst cases – health problems, these are the issues that could occur if you neglect to heat your home.
Abstract. Background: Cold ambient temperatures are known to increase blood pressure (BP), but the influence of room temperature remains understudied.
Health Effects that a Lack of Heating Can Cause
If you are living in a house that is classed as too cold, then you are increasing your chances of suffering from general illnesses, blood pressure rises, cardiovascular disease, respiratory illnesses such as asthma, and even pneumonia.

Heater Broken? 5 Ways to Stay Warm Until the Furnace Repairman Comes
Pipes can begin to freeze when temperatures drop to 20°F or below, especially if exposed to wind or located in unheated spaces. Pipes in exterior walls or unheated areas are at risk even in the upper 20s.
Likely places for frozen pipes include against exterior walls or where your water service enters your home through the foundation.
To effectively protect your plumbing, you need to know the ideal temperature for dripping faucets. It's recommended to drip your indoor faucets when outside temperatures are expected to fall below 20°F for 3 hours or more. This proactive measure helps mitigate the risk of frozen pipes significantly.
What Temperature is Too Cold for a House? While everyone has a different tolerance to cold, ideal winter heat settings should generally be at or above 63 °F (17 °C). Excessive cold (anything below 62 °F or 16 °C) in your home can actually raise your blood pressure as your blood “thickens” in the chilly temperatures.
What's the best temperature to set my central heating to? You should set your thermostat to the lowest comfortable temperature for your needs. For most people, this is between 18°C and 21°C. If you can, turning down your thermostat from 22°C to 21°C can save £90 a year in GB and £80 in NI on energy bills.
The best room temperature for sleep is approximately 65 degrees Fahrenheit (18.3 degrees Celsius). This may vary by a few degrees from person to person, but most doctors recommend keeping the thermostat set between 65 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius) for the most comfortable sleep.
While chances of freezing to death in your home are small, there's a greater danger of death by fire, lack of oxygen or carbon monoxide poisoning.
Losing your home's heating is considered an emergency when it's 40 degrees or colder outside. Within just a few hours, a lack of heat can cause indoor temperatures to become uncomfortable and ultimately unhealthy, especially for the young and elderly or those with underlying health conditions.
On average: At 20°F: Pipes can freeze in 6 hours or less. At 15°F: Pipes can freeze in 3–4 hours. At 10°F or below: Pipes may freeze in under 2 hours.
