Why Is My House Colder Than Outside: Surprising Explanations
Why Is My House Colder Than Outside?
There are several reasons why a house may feel colder than outside.
First, indoor air is often drier in winter, causing sweat to evaporate faster and cooling the skin.
Additionally, drafts and pockets of colder air near the floor can contribute to a colder indoor temperature.
The walls in the house are also colder and emit less infrared radiation, resulting in heat loss as our bodies emit more infrared than they receive.
Spending more time indoors during winter may lead to less physical activity and less heat generation by the body.
Heat flow plays a role in temperature perception, with conduction, convection, and radiation all affecting how we feel heat.
Moreover, spending more time outside in colder conditions can lower our temperature threshold as our body adapts to the cold.
Lastly, windy days result in more heat loss from the body compared to calm days, as cooler air constantly replaces it.
Key Points:
- Indoor air being drier in winter causes sweat to evaporate faster and cools the skin

Did You Know?
1. Did you know that heat is actually the movement of thermal energy from warmer objects to cooler ones? So if your house feels colder than outside, it might be due to the fact that heat is escaping from your indoor environment and transferring to the colder outdoor environment.
2. Many older homes were not constructed with proper insulation, which can contribute to the sensation of a colder indoor environment compared to outside. If your house lacks sufficient insulation, it can result in heat loss and make it feel cooler indoors.
3. Another reason your house might feel colder than outside is due to drafts or air leaks. Small gaps or cracks in doors, windows, walls, or ceilings can let cold air seep inside while allowing warm air to escape. These drafts can significantly cool down your home.
4. Objects and materials within your house, such as furniture, flooring, or walls, can affect the temperature perception. Some materials, like tile or concrete, tend to feel cooler to the touch compared to others, like carpet or wood. Spending time near colder materials can contribute to the feeling of your house being colder than outside.
5. The phenomenon known as wind chill can also play a role in making your house feel colder than the actual outdoor temperature. When there are strong winds outside, they can increase the rate at which heat is transferred from your body and the surfaces in your house, making it feel colder than it really is.
Dry Air And Faster Sweat Evaporation
During the winter months, it is common to perceive your house as colder than the outside temperature. This is because indoor air tends to be drier during this time of the year. In colder weather, the air holds less moisture, resulting in lower relative humidity levels. As a result, sweat evaporates quickly from your skin, leaving you with a sensation of coolness.
The process of evaporation requires energy, which is taken from your body. When sweat evaporates, it absorbs heat from your skin, making you feel chilly. This explains why your house feels colder, even if the outside temperature is lower. Furthermore, low humidity levels can contribute to dry and irritated skin, as well as respiratory issues such as a dry throat or nasal passages.
Drafts And Cold Patches Near The Floor
Another reason your house may feel colder than the outside is the presence of drafts and pockets of colder air near the floor. Poor insulation or gaps in windows and doors could allow cold air to seep into your home, creating localized areas of low temperature. Heat has a natural tendency to rise, so colder air tends to settle near the ground. This phenomenon is particularly noticeable in houses with basements or crawl spaces.
Drafts not only make the environment feel colder, but they also can exacerbate the effects of cold air on your body. When a draft hits your skin, it enhances the sensation of coolness and can make you feel even colder. By addressing draft issues and ensuring proper insulation, you can create a more comfortable indoor temperature and reduce the discrepancy between the house and the outside.
Cold Walls And Heat Loss
The walls within your house can contribute to the sensation of it being colder indoors compared to outside. When the temperature drops, your body tries to maintain its own warmth by emitting infrared radiation. However, walls and other objects in your home tend to be cooler during the winter months. This results in the emitted infrared radiation being absorbed by the surrounding surfaces rather than being reflected back to your body.
As a consequence, heat loss occurs more rapidly, making your body lose more heat than it receives. This continuous heat loss can leave you feeling colder indoors, even when the outside temperature is lower. To mitigate this issue, you can consider insulating your walls, using thermal curtains, or adding additional layers of clothing to combat the heat loss.
Less Physical Activity, Less Body Heat
During the winter season, people often spend more time indoors, which can lead to a decrease in physical activity levels. While spending time inside can be warm and cozy, it also means that you are generating less body heat through movement. The energy produced by physical activity helps to keep your body warm and maintain a comfortable internal temperature.
By reducing physical activity and staying sedentary for extended periods, your body has less heat generation. This can contribute to feeling colder indoors compared to outside, where you may engage in more physical activities. Incorporating regular exercise or activities that generate body heat can help counteract this effect and make your indoor environment feel warmer.
Heat Flow And Temperature Perception
The perception of temperature is influenced by heat flow, which occurs through three main mechanisms: conduction, convection, and radiation.
- Conduction refers to the transfer of heat between solid objects that are in direct contact, such as sitting on a cold chair.
- Convection involves the movement of heat through a fluid, like warm air rising and cold air sinking.
- Radiation is the transfer of heat through electromagnetic waves, such as heat from a fireplace reaching your skin.
Understanding these heat transfer processes is important when considering why your house may feel colder than the outside.
- Drafts and cold patches near the floor can enhance convection, making you feel colder even if the actual air temperature is not significantly different.
- Cold walls contribute to heat loss through radiation, increasing the discrepancy between indoor and outdoor temperatures.
By addressing these heat flow factors, you can create a more comfortable indoor environment.
In conclusion, several factors can explain why your house feels colder than the outside during the winter months. Dry air and faster sweat evaporation, drafts and cold patches near the floor, cold walls and heat loss, less physical activity leading to decreased body heat, and the influence of heat flow on temperature perception all contribute to this phenomenon.

Frequently Asked Questions
What to do when your house is colder than outside?
When faced with a house that is colder than the outside, there are simple steps to take for warmth and comfort. Firstly, instead of just opening windows at noon, it can be beneficial to strategically place dark-colored curtains or blinds on the windows as they absorb sunlight and radiate heat into the house. Additionally, incorporating physical activity into your daily routine can help generate body heat and make you feel warmer. Whether it is a brisk walk or engaging in household chores, the movement will naturally raise your body temperature and provide a cozy environment within your home.
Why is my house so cold inside?
Your house might be feeling unusually cold due to inadequate insulation in key areas. Over time, the insulation in your house and attic can become worn down, leading to heat escape and unwanted airflow. Additionally, hidden attics that lack proper insulation or uninsulated garage walls that are connected to your home can contribute to drafts and cold air seeping into your living space. These issues combined can result in a colder interior temperature and a less comfortable environment within your home.
Why is my living room so cold?
The reason your living room is feeling so cold might be due to leaky ductwork. Leaks, cracks, and gaps in the ductwork can lead to a loss of air, resulting in an under-heated living space. To address this issue, it is essential to patch up the ductwork and seal any areas of air loss. This will help ensure that the warm air reaches your living room and makes it more comfortable.
Why is my house cold in winter and hot in summer?
The temperature discrepancy in your house during different seasons can be attributed to several factors. Firstly, your thermostat only measures the temperature at its specific location, which might not accurately represent the overall temperature in your home. Secondly, heat exchange primarily occurs through your windows, which can contribute to the imbalance. During the winter, colder air outside causes the glass to be cooler, making the interior of your house feel colder. In contrast, during the summer, the windows absorb and radiate heat, making your home warmer.
