Yes!  The NovoTHOR PBM Therapy Whole Body Light Bed is not like the tunnels that you get with an MRI or CT Scan.  The top of the light bed hinges open - much like a clam shell, so we can leave the lid half open or fully open its up to you.   Many people with claustrophobia find that when they get onto the NovoTHOR their fear goes away (even with the lid closed) because their head is so close to the open 'top end'.
If the NovoTHOR is partially or fully open then the amount of light reaching your body - the irradiance - is likely to be a little less than if you were covered, so this may increase the number of treatments needed to get a benefit or maintain a benefit.
