Infra red lamp definitely the best way to warm up
I just got my infra red lamp today and it’s great
I have been using a flannel run under hot water or a wheat bag that’s been in the microwave for 1min up until now,
Problem with the flannel is obviously you get wet, I use a Penimaster so I don’t really wanna be wet else it will keep slipping off!
Problem with the wheat bag is you have to hold it there for the full 5mins or whatever and it loses it’s heat rapidly.
I have to say the infrared lamp is easily my favourite, just sit there basking the the red glow and let the lamp do all the work for you!
Hope this helps someone in someway
