Head noise (tinnitus) can be caused by broken or damaged hairs on auditory cells, turbulence in a carotid artery or jugular vein, temporomandibular joint (TMJ) issues, and problems in the auditory processing pathways of the brain. Tinnitus (TIN-ih-tus) is the perception of noise or ringing in the ears. A common problem, tinnitus affects about 1 in 5 people. Tinnitus isn't a condition itself â it's a symptom of an underlying condition, such as age-related hearing loss, ear injury or a circulatory system disorder. Although bothersome, tinnitus usually isn't a sign of something serious. Although it can worsen with age, for many people, tinnitus can improve with treatment.

Under natural conditions, the cotton bolls will tend to increase the dispersal of the seeds.he Greeks and the Arabs were not familiar with cotton until the Wars of Alexander the Great, as his contemporary Megasthenes told Seleucus I Nicator of there being trees on which wool grows in Indica. This may be a reference to tree cotton, Gossypium arboreum, which is a native of the Indian subcontinent.
