Answer 1

Answer 2

Hey sis ✯✯

brain-freeze:

Once activated, the blood vessels constrict from the cooling. To adjust to the drastic temperature change, your body sends more blood to warm the affected area, causing the blood vessels to swell. It's believed that “brain freeze” pain is caused by the constriction and then rush of blood.
