What is Headache From Heater?

Headache from heater is common during the winter. Some people wake up in the morning with a headache due to the heater. 

The heater may cause sinus congestion, asthma, and associated headaches when you start it for the first time during winter. That is because the dirty filter of the heater may contain dust, pollens, and certain allergens.

The heater filter should be cleaned before starting it for the first time. After that, checking the heater once a week or at a suitable interval is a good habit. 

The heater also reduces the room’s humidity and produces dry skin, conjunctivitis, and other symptoms. Using a humidifier along with a heater can be an option.  

Heat itself can cause headaches, whether it’s environmental or provided by your heater. 

How the headache occurs by a heater, what factors trigger it, and how it can be relieved are all covered in this article.

Headache From Heater Causes

Headache from the heater does not always cause by the heat itself. Instead, it often occurs due to our body responses to certain factors regulated by the home heater. 

Heater Regulated Triggering Factors 

  • Sudden raised heat/temperature
  • Low humidity
  • Dust, pollens, and other allergens
  • Sudden change in air pressure
  • Blow of hot air
  • Stucked smelling air
  • Overheating

Headache from the heater can be caused by dehydration. People often reduce their water intake during the winter. As a result, when the heater is raising the room temperature, the body needs more water than usual. 

Taking low water can cause headaches and migraine. 

Temperature changes affect the body’s serotonin level. Also, when you enter the home from outside cold temperatures, the body’s serotonin level changes, which can cause sudden dizziness and migraine in some individuals. 

Maintaining an ideal room temperature is necessary. However, increasing the heater temperature is not suitable for your body and health. Instead, try to keep the temperature constant and comfortable.

When To See The Doctor

Headaches from the heater usually go away within one to three hours. However, sometimes the headache persists for more than a few hours, and it comes with additional signs and symptoms. 

You should seek the doctor if you face any of the following symptoms;

  • Persistent nausea and vomiting
  • High-grade fever
  • Unbearable intense pain
  • Slurring of speech

The heater sometimes triggers a sinus headache. Using hypoallergenic lotion or saline nasal spray would help in that case. 

If you have a sinus headache, consult with a doctor and follow their instructions. 

Headache From Heater Prevention

When we know the absolute and relative causes of the headache caused by the heater, we can prevent a headache by compensating for those causes. 

Clean the Heater Filters

Clean the room or car heater filters before starting them for the first time. Then, open the windows and let the stuck air get out. 

Maintain a routine of cleaning the heater at least once a week. 

Maintain An Ideal Temperature

Try not to keep the heater temperature too high or too low, and please do not change the temperature frequently. Your body will adjust to the temperature within a few days. If you change the temperature too frequently, it may affect you adversely.

Use Humidifier

While the weather is cold and using a heater within your home or car, makes the environment drier. 

The dry air absorbs the water from your body and causes dehydration headaches. It also causes some additional symptoms. 

Using an air humidifier can solve that problem. If you are not buying an air humidifier, keep a water bowl near the heater.

Avoid Sleeping With Heater On

It may sound stupid to off the heater during sleep time in winter. If turning off the heater is not for you, lower the temperature a bit to avoid the morning with a headache. 

Drink Enough Water

The heaters make the air of the room or card hot and dry. The dried air absorbs the water from your body surface, which may lead to dehydration, consequently, dehydration headache. 

Drink at least 1.5L of water a day. 


Understanding how the heater causes headaches would solve the problem. Uncleaned heater filter, high temperature, dehydration, dry air, sinus conditions are the leading causes of headache from the heater. 

Taking some precautions and maintaining an ideal temperature solve the headache problem in most cases. 

However, if you are experiencing a headache from using the heater and it is not going away within a few hours, do not hesitate to consult a doctor.
