Yes, it is completely normal and can be beneficial. This happens because the blood flow to the brain, eyes, skin, and hair increases while inverting. Studies have shown that the brain functions faster and more accurately while inverted. However, if you are new to inversion therapy and find this sensation uncomfortable, it is okay to rest and practice intermittent traction, where you alternate between being upright and inverted. Oscillation, a rhythmic rocking motion, is also a good technique to help you adjust to the inverted position. Over time, the feeling of pressure will decrease as you become more accustomed to inversion therapy.
