“When your indoor heater is turned on, the air is heated, which in turn lowers relative humidity, making the air inside your home even drier.” Dry air pulls moisture from your body and dries out your skin along with the mucus membranes inside your nose, throat and eyes, explains Checkley.
Carbon Monoxide: If you're using a gas heater, improper ventilation can lead to carbon monoxide buildup, which is dangerous and can cause symptoms like headaches, dizziness, and nausea.
If you use a gas heater, there is a risk of carbon monoxide exposure if the heater isn't well-maintained. Carbon monoxide is a dangerous, odourless gas that can cause headaches, dizziness, and nausea if inhaled in large amounts. Regular maintenance and good ventilation are essential for safety.
“Another option is to keep a bowl of water nearby to reduce the dryness in the room,” she says. Keeping your nasal passages moistened is one way to treat dry sinuses caused by turning on your heater. Dabbing a hypoallergenic lotion on your nostrils or using a saline nasal spray can also help alleviate these symptoms.
Because hot weather triggers heme oxygenase-1 to speed up the normal breakdown of heme proteins, which releases carbon monoxide, which makes you nauseous.
Other factors that make a person susceptible to heat illness include older age, heart disease, other chronic diseases, extreme exercise, sunburn, obesity, sleep deprivation, alcoholism and certain medications.
The combination of fluid loss/dehydration from sweating, with lower blood pressure as a result of all those extra dilated blood vessels, can start to lead to more serious problems and can cause dizziness and fainting, or heat syncope.
For most people, Lizarzaburu says that, for most people, heater illness symptoms shouldn't last more than a few days.
Radiators heat the air in a room and as the air warms up, it rises in a process known as convection. This causes the warm air to move, which can circulate dust around the room. "If dust is circulated around the room, you can end up inhaling it, which can worsen asthma symptoms," says Jarvis.
Improperly maintained or faulty fuel-burning heaters can release carbon monoxide gas, which is odourless and colourless. Breathing in high levels of carbon monoxide can lead to carbon monoxide poisoning, resulting in symptoms like headaches, dizziness, nausea, and can even be fatal in extreme cases.
Carbon monoxide (CO) is a colorless, odorless, tasteless gas. A by-product of combustion, it can be produced by ordinary appliances, and is a common hazard in the home. Mild exposure can cause symptoms such as nausea, dizziness, or headaches; while severe poisoning can result in brain or heart damage or even death.
Sleeping with the heater on increases the levels of carbon monoxide in the room. People with heart disease may get chest pain, while smokers with heart disease are particularly at risk, so are young children and elderly. The risk of asphyxia (sleep death) is high when using gas heaters.
Heat exhaustion is a condition that happens when your body overheats. Symptoms may include heavy sweating and a rapid pulse. Heat exhaustion is one of three heat-related illnesses, with heat cramps being the mildest and heatstroke being the most serious.
Exposure to these indoor pollutants can cause allergies, asthma, as well as irritation to the eyes, nose, and throat. This problem is more pronounced in warmer climates, such as when your home is heated in the winter. Furthermore, as mentioned above, dust and debris get trapped in the HVAC ducts and vents.
Poor circulation
Underlying arterial disease could be causing inadequate blood circulation, making it hard to maintain core body temperature, especially in your extremities. Smoking affects temperature regulation in a similar way by causing blood vessels to constrict.
General Symptoms:
Heavy sweating. Painful muscle cramps. Extreme weakness and/or fatigue.
Yes, low estrogen levels can cause heat intolerance, particularly in women experiencing perimenopause or menopause. Estrogen plays a key role in regulating body temperature and can lead to symptoms such as hot flashes and night sweats when levels are low.
One of the most common reasons for heater sickness is unclean air. The EPA estimates that indoor air can be between 2 and 5 times more polluted than the air outside, and a faulty heater can ramp up those pollutants in no time.
Conditions that can cause heat intolerance.
You may develop this symptom if you have an anxiety disorder, if you're in menopause, or if you have thyrotoxicosis (when your thyroid gland makes too much thyroid hormone) from any condition, like hyperthyroidism.
Lay the person down and raise the legs and feet slightly. Remove tight or heavy clothing. Have the person sip chilled water, a sports drink containing electrolytes or another nonalcoholic beverage without caffeine. Cool the person by spraying or sponging with cool water and fanning.
Heat intolerance is also called heat hypersensitivity. It happens when your body does not regulate its temperature correctly and cannot maintain a balance between cold and hot. Heat intolerance causes a more extreme reaction than many people's discomfort when temperatures rise.
