Raynaud's and Infrared Heating: Can It Help Keep Your Home Comfortable?

What is Raynaud's?

Raynaud's phenomenon affects blood circulation. During an attack, the blood vessels supplying areas such as the fingers and toes become narrower and blood flow is temporarily restricted.

According to the NHS, episodes can be triggered when a person is cold, anxious or stressed. Fingers and toes may change colour and symptoms can include pain, numbness and pins and needles.

Some people also experience symptoms in other areas, including the ears, nose, lips or nipples. Episodes may last from a few minutes to several hours.

Scleroderma and Raynaud's UK estimates that around 10 million people in the UK are affected by Raynaud's.

Why keeping warm matters with Raynaud's

Because exposure to cold and changes in temperature can trigger Raynaud's attacks, warmth is an important part of day-to-day symptom management.

Heating is therefore relevant because it helps control the indoor environment – not because the heater itself is treating Raynaud's.

How does infrared heating work?

Infrared heating works differently from heating systems that rely primarily on warming and circulating room air.

An infrared heater emits radiant energy that is absorbed by people and surfaces within its field of radiation. Those surfaces then warm and contribute heat to the room.

Radiant heat is also the reason you can feel warmth from the sun even when the surrounding air is relatively cool, although domestic infrared heaters obviously operate at very different temperatures and energy levels from sunlight.

To understand the process in more detail, see our guide on how infrared heaters work.

How could infrared heating contribute to a comfortable home?

It is important to distinguish between thermal comfort and a medical benefit. There is no established basis for claiming that domestic infrared heating treats Raynaud's.

There are, however, characteristics of radiant heating that may be useful when designing a warm home environment.

Creating a warmer indoor environment

If cold is a concern, the complete thermal performance of the home matters more than the heater alone.

The NHS also advises heating your home to a temperature that is comfortable for you. Its general winter guidance states that, where possible, regularly used rooms such as living rooms and bedrooms should be at least 18°C, particularly for people with health conditions.

That does not mean 18°C is necessarily the correct comfort temperature for every individual. People who are particularly sensitive to cold may prefer a different setting.

Correct heater sizing is important

Simply fitting an infrared heater does not guarantee that a room will remain comfortably warm.

The amount of heating required depends on factors including:

• Room dimensions
• Ceiling height
• Building age and insulation
• External walls
• Windows and glazing
• Room use
• Overall heat loss

An undersized heating system may struggle to maintain the required room temperature during colder weather.

You can estimate the required output for individual rooms using our wattage calculator.

Heater placement also affects comfort

Because infrared heaters provide radiant heat, their position influences where that radiation is directed.

A correctly positioned wall or ceiling panel can help distribute radiant warmth through the occupied area of a room, while poor positioning or obstruction can reduce its effectiveness.

Heater location should therefore be considered alongside wattage rather than simply choosing an available wall and mounting the panel there.

Is infrared heating suitable for a home where someone has Raynaud's?

Infrared heating can be considered in the same way as other home heating options: by looking at whether it can maintain the required indoor temperature, suit the building and provide the type of comfort the occupants prefer.

For someone with Raynaud's, the medically relevant point is that keeping warm and avoiding sudden temperature changes are recognised self-management measures. The NHS does not specifically recommend infrared heating over other heating technologies. :chatgpt-content-reference{index="2"}

The decision to use infrared should therefore be based on its characteristics as a heating system rather than a claim that it has a specific therapeutic effect.

Frequently Asked Questions

Raynaud's and Infrared Heating: The Bottom Line

Infrared heating does not cure, treat or prevent Raynaud's, and it should not be marketed as doing so.

What we can say is that cold is a recognised trigger for Raynaud's and the NHS recommends keeping the home warm and avoiding sudden changes in temperature. :chatgpt-content-reference{index="3"}

Infrared heating provides radiant warmth to people and surrounding surfaces and can be designed with room-by-room thermostatic control. For households that prefer this style of heating, it can be one way of creating a warm and comfortable indoor environment.

The important distinction is that the benefit is the provision of suitable home heating – not a claimed medical effect of infrared radiation itself.
