Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...
These movements can lead the patient to wake up, and if so, sleep interruption can be the origin of excessive daytime sleepiness.

Sleep apnea is a common sleep disorder that affects more than 20 percent of people in the United States. It happens when your breathing temporarily stops while you sleep. Depending on the severity ...
Sleep apnea is measured by the apnea-hypopnea index (AHI). An AHI is determined with a sleep study. AHI values for adults are categorized as: [2] [3] Normal: AHI<5; Mild sleep apnea: 5≤AHI<15; Moderate sleep apnea: 15≤AHI<30; Severe sleep apnea: AHI≥30; An episode is when a person hesitates to breathe or stops their breathing altogether.
A number of computer and smartphone applications adjust the computer video color temperature, reducing the amount of blue light emitted by the screen, particularly at night. Dry eye is a symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.
