Unterschied zwischen Wärme von Infrarotlampe und Wärmepad?

2 Antworten

Therapeutisch sollte meiner Einschätzung kein Unterschied bestehen. Wenn therapeutisch Wärmezufuhr angesagt ist, dann sollte die Wärmequelle selbst keine Rolle spielen. Die Physik kennt drei Arten des Wärmetransports.

Die Wärmeleitung durch Kontakt eines warmen Körpers mit einem kalten. Wärmeflasche

Wärmeübertragung durch Stofftransport. Die umlaufenden Wassermengen in einer Zentralheizung nehmen die Wärme mit. Ein Föhn pustet heiße Luft durchs Haar. Das wäre das gleiche Prinzip.

Wärmestrahlung: Die Sonne transportiert sämtliche Wärme allein über den Strahlungsweg über 150 Mio km durch das Vakuum des Weltalls. Deine Infrarotlampe transportiert auch durch Strahlung.

Wäre noch zu ergänzen, dass die Wärmflasche natürlich auch ein wenig strahlt.

Ich habe dann noch ChatGPT gefragt und finde, die Antwort ist mega hilfreich und möchte ich daher hier posten:

User: What is the physical difference between the warmth, that is provided by an infrared lamp, and the warmth, that is provided by a hot-water bag?

ChatGPT: The warmth provided by an infrared lamp and a hot-water bag is different in terms of the way they transfer heat to the body.

An infrared lamp emits infrared radiation, which is a type of electromagnetic radiation that can penetrate the skin and heat up the body directly. The heat from an infrared lamp can penetrate deeper into the body compared to the warmth provided by a hot-water bag.

On the other hand, a hot-water bag provides warmth by conduction. The bag is filled with hot water, and the heat is transferred to the body through direct contact with the bag. The warmth provided by a hot-water bag is more localized and tends to cool down faster than the warmth from an infrared lamp.

Overall, the main difference between the two types of warmth is the method of heat transfer. An infrared lamp heats the body directly with electromagnetic radiation, while a hot-water bag provides warmth through conduction.

User: Why does the heat from electromagnetic radiation penetrate deeper into the body compared to heat provided by conduction?

ChatGPT: The heat from electromagnetic radiation, such as that produced by an infrared lamp, can penetrate deeper into the body compared to heat provided by conduction, such as that provided by a hot-water bag, because of the way that heat is transferred through each process.

Conduction transfers heat through direct contact between two objects, such as the hot-water bag and the skin. The heat is conducted from the warmer object to the cooler object until they reach thermal equilibrium. Because the heat transfer occurs through direct contact, the warmth provided by a hot-water bag tends to be localized and doesn't penetrate very deeply into the body.

In contrast, electromagnetic radiation, such as that produced by an infrared lamp, can penetrate through the skin and into deeper tissues because it is a form of energy that travels through space. When the electromagnetic radiation reaches the body, it is absorbed by the body's tissues, and the energy from the radiation is converted into heat. Because the radiation can penetrate deeper into the body, the warmth produced by an infrared lamp can heat up tissues that are located further beneath the surface of the skin.

Overall, the different methods of heat transfer result in different patterns of heat distribution in the body. The warmth provided by an infrared lamp is more evenly distributed and can penetrate deeper into the body than the warmth provided by a hot-water bag.
