Nowadays, every fourth person suffers under sleep disturbances. The international classification of sleep disturbances (ICSD-3), published by the American Academy of Sleep Medicine (AASM), differentiates between 97 different sleep disturbances. For being able to regenerate, body and mind need regularly sufficient sleep. A lack of sleep has severe consequences. But, when do we talk about a sleep disturbance? Then, when over a period from one to three months the problem is occurring at least three times a week.
Causes of sleeplessness
The causes are manifold. The most common causes for falling asleep or sleeping through disturbances are stress or mental illnesses. Wrong handling of sleep might also be a trigger of sleeplessness as well as irregular sleeping times. Here, shift workers and nurses are especially concerned. A further reason for sleep disturbances also might be psychiatric disorders like depressions, anxiety or eating disorders.
Forms of sleeplessness
Sleep disturbances can be divided into six main groups:
- Insomnias: disturbances to fall asleep or to sleep through
- Sleep apnoea: a sleep related respiratory disorder. Here, slackening throat muscles cause a blockage of the upper airways during the night. This life-threatening sleep disorder has many consequences: increased blood pressure and hence increased stroke- and infarction-risk, risk of brain damages due to oxygen deficiency, daytime sleepiness due to several arousals (mostly unaware), etc.
- Hypersomnia: their causes are in the central nervous system. Example: narcolepsy.
- Parasomnia: night mares, sleep walking and nocturnal outcry
- Disturbances in the circadian rhythm: a disturbance of the inner clock
- Sleep related movement disorders: restless legs or nocturnal teeth grinding (bruxism)
Impacts and consequences
Sleepless nights and their consequences are not only affecting our health but also our everyday life. Side effects caused by sleeplessness are diminishing performance, state of exhaustion and extreme tiredness. Once sleep disturbances become chronic the consequences might be far worse.
Generally, seek medical advice when your sleeping problems are longer lasting. But, there are some simple things you can do to support your sleep. At any case, a regular sleep-wake-cycle or relaxation methods like autogenous training, for example, are to be preferred to medication.
