What to do: See your dentist for an exam. Bite problems are often a cause of bruxism, and it's a good idea to check for damage to your teeth. It's likely she'll suggest lifestyle changes, such as cutting out alcohol before bed. If you chew gum, stop -- the habitual chewing action can make it more likely you'll grind your teeth at night. Wearing a dental guard or splint at night is usually the next step for bruxism. Your dentist will fit you with a device that prevents your jaw from clenching. Other treatments include Botox injections to the jaw muscle, and a biofeedback device called Grindcare.
Apnea means "no airflow." Obstructive sleep apnea was thought to be a disorder primarily of overweight, older men. But abnormal breathing during sleep can affect people of any age, any weight, and either sex. Researchers now know that in many cases of sleep apnea, the obstruction in the airways is only partial. Most people with sleep apnea have a smaller-than-normal inner throat and other subtle bone and soft-tissue differences.
The natural internal clock that controls our 24-hour cycle of sleep and waking, circadian rhythms are easily upset by changes in schedule, and they're greatly affected by light and darkness. Jet lag is the best known circadian rhythm disorder, but this sensitive inner clock can also be disrupted by changes in routine resulting in an erratic sleep schedule.
