Vibrating Isa can do this. Isa can slow down anything, stagnate anything, bind anything.
It can slow down growth but also decay, it can slow down emotions and feelings, etc.
Just be careful when applying Isa to yourself, don’t invoke it unless you really know what you are doing and often just a few vibrations can be enough to do the trick.
I have used Isa to cool myself down, and to make fever more tolerable when I had it, often no more than 9 vibrations were needed for this to work.
Heat is caused by vibration as I’m sure you know. The radiation from the sun bombards the atoms and etc here on Earth, causing them to vibrate faster and faster, which heat everything up.
Isa can be used to slow these vibrations down and make it more tolerable if it is so hot you can’t bear it.
Vibrate it and visualize it slowing down your environment, preferably avoid applying it directly to yourself (I had accidentally wrongly invoked Isa a couple of times, causing great lethargy to myself for a few days, but it can be done in small reps if you are careful and know what you are doing to do things like slow down and infection or lower a fever, or calm your emotions if you are overly emotional in some way, etc).
To practice this I tried placing my hand into as hot of water I could endure without harming myself and vibrating Isa to try and make it feel more tolerable.
From this I also found Isa can also slow down pain and other unwanted sensations (very useful if you stub your toe or something else which causes a lot of pain without doing any actual harm).
Just remember to be careful with it. The Isa rune is extremely versatile but can also be very harmful when wrongly applied.
