How to use ices while sleeping

[cognito]

Hello ,

i bought the m1 recently and want to use it on my head while im sleeping .
but im not sure about 2 things : which frequency and where exactly should i place the coils ?
i read that some people just put the coils under the pillow and stack it bumpy side into bumpy side
and im thinking of using the delta frequency on a low intensity like 4 or do you have better ideas ?

IMO, you have a good plan to start with Delta power 4. Some respond fine to Omni 8 and other protocols and sleep deeper as well. You probably saw this thread? Thoughts on Sleep . The key to all this is self experimentation, observing and documenting changes, sharing back etc. Looking forward to hearing how it works for you.
