The invention relates to a nasal dilator comprising magnets. According to the invention, the nasal dilator is a set comprising two bodies, each of the two bodies having - a first leg having at a distal portion thereof a magnet and - a second leg connected to the first leg via a bridge comprising flexible material, each of said two bodies being designed so as to allow said body to be clamped to an ala nasi of a human nose between the distal portions of said first leg and said second leg the magnet of a body being aligned such that with a body clamped to the ala nasi of a nose, the magnet is oriented at an angle to a plane defined by the ala nasi area clamped between said two distal portions of said first leg and second leg. Thanks to the repelling action of the magnets, the alae nasi are pushed apart, resulting in improved ease of breathing.
