Changing sleep position
More than half of people with obstructive sleep apnea have some degree of positional obstructive sleep apnea, meaning that it gets worse when they sleep on their backs. Sleeping on their sides is an effective and cost-effective treatment for positional obstructive sleep apnea. Continuous positive airway pressure
For moderate to severe sleep apnea, the most common treatment is the use of a continuous positive airway pressure (CPAP) or automatic positive airway pressure (APAP) device. These splint the persons airway open during sleep by means of pressurized air. The person typically wears a plastic facial mask, which is connected by a flexible tube to a small bedside CPAP machine.Although CPAP therapy is effective in reducing apneas and less expensive than other treatments, some people find it uncomfortable. Some complain of feeling trapped, having chest discomfort, and skin or nose irritation. Other side effects may include dry mouth, dry nose, nosebleeds, sore lips and gums.Whether or not it decreases the risk of death or heart disease is controversial with some reviews finding benefit and others not. This variation across studies might be driven by low rates of compliance—analyses of those who use CPAP for at least four hours a night suggests a decrease in cardiovascular events. Weight loss
Excess body weight is thought to be an important cause of sleep apnea. People who are overweight have more tissues in the back of their throat which can restrict the airway, especially when sleeping.
Trichorrhexis nodosa is a defect in the hair shaft characterized by thickening or weak points (nodes) that cause the hair to break off easily. : 766 : 636  This group of conditions contributes to the appearance of hair loss, lack of growth, and damaged-looking hair. Symptoms
Among the symptoms (and signs) for this condition are the following:

lack of apparent hair growth
hair appears patchy
hair breaks easily close to scalp
hair may have thickenings or nodes in the shaft
ends of hair thinned or split
whitish discoloration of hair tips
hair breaks easily at tips

Complications
This condition is not dangerous but may affect self-esteem. Causes
Trichorrhexis may have a genetic basis but appears to be precipitated by environmental factors. Among Caucasians the defect often appears at the ends of the hair shaft with splitting of the ends, thinning and whitish discoloration. These conditions are directly related to environmental causes such as "perming", blow drying, aggressive hair brushing, and excessive chemical exposure. In some cases, trichorrhexis nodosa may be caused by an underlying disorder such as argininosuccinic aciduria, Menkes kinky hair syndrome, Nethertons syndrome, hypothyroidism,  or trichothiodystrophy. Diagnosis
Examination of the hair shafts with a microscope may reveal changes of trichorrhexis nodosa. Prevention
Avoid aggressive brushing and grooming, strong chemicals, permanents, straightening, and similar hair-damaging habits. Treatment
Improving environmental factors will reduce damage to the hair. Gentle brushing with a soft brush should replace more aggressive brushing, ratting, or other procedures. Harsh chemicals such as hair straightening compounds and permanents should be avoided. The hair should not be ironed. Excessively harsh shampoo should be avoided. Hair conditioners should be used.
