The pineal gland, located within the brain's two hemispheres, receives signals from the SCN and increases production of the hormone melatonin, which helps put you to sleep once the lights go down.
Physical health conditions
Insomnia can also be caused by underlying physical conditions, including: heart conditions – such as angina or heart failure. respiratory conditions – such as chronic obstructive pulmonary disease (COPD) or asthma. neurological conditions – such as Alzheimer's disease or Parkinson's disease.
Common conditions often associated with sleep problems include heartburn, diabetes, cardiovascular disease, musculoskeletal disorders, kidney disease, mental health problems, neurological disorders, respiratory problems, and thyroid disease.
“Sleep affects almost every tissue in our bodies,” says Dr. Michael Twery, a sleep expert at NIH. “It affects growth and stress hormones, our immune system, appetite, breathing, blood pressure and cardiovascular health.” Research shows that lack of sleep increases the risk for obesity, heart disease and infections.
General health conditions
Breathing problems, such as sleep apnea. Obesity. Alcohol consumption and smoking. Digestive issues such as irritable bowel syndrome and acid reflux.
Common causes of chronic insomnia include: Stress. Concerns about work, school, health, finances or family can keep your mind active at night, making it difficult to sleep. Stressful life events or trauma — such as the death or illness of a loved one, divorce, or a job loss — also may lead to insomnia.
Some people with insomnia experience changes in their sleep cycles and, as a result, may have more stage 1 sleep and less deep sleep. Stress and aging can also reduce levels of deep sleep. Additionally, people with conditions such as schizophrenia and Alzheimer's disease experience less slow wave sleep.
The top ones are: Insomnia. Sleep apnea. Restless legs syndrome.
Common neurologic disorders that are accompanied by sleep problems and disorders include: Alzheimer's disease and other dementias. Epilepsy. Neuromuscular disorders.
Abstract: Sleep disturbance is a common feature of chronic liver disease (CLD) with impact on health-related quality of life; 60–80% of patients with CLD report subjective poor sleep; frequent presentations of sleep disturbance include insomnia, reduced sleep efficiency, increased sleep latency, reduced time in rapid ...
Sleep–wake disturbances are common in liver cirrhosis and associated with impaired quality of life. The most common abnormalities are insomnia (difficulties falling asleep and maintaining sleep, or unrefreshing sleep), excessive daytime sleepiness, and sleep–wake inversion (disturbances of circadian rhythmicity).
There are many causes for insomnia, ranging from jet lag to serious health problems. Fatty liver disease is another potential cause of insomnia. Fatty liver disease occurs when fat accumulates in the liver, this excess fat can keep the liver from functioning properly and removing toxins from the blood.
Keep your bedtime and wake time consistent from day to day, including on weekends. Stay active. Regular activity helps promote a good night's sleep. Schedule exercise at least a few hours before bedtime and avoid stimulating activities before bedtime.
Many factors can cause a person to wake up often at night. Needing to urinate is a common reason, but sleep apnea, overheating, and dietary habits are just a few of the others. However, regularly waking up in the middle of the night can become problematic, as it interrupts sleep.
Hypersomnia means excessive sleepiness. There are many different causes, the most common in our society being inadequate sleep. This may be due to shiftwork, family demands (such as a new baby), study or social life. Other causes include sleep disorders, medication, and medical and psychiatric illnesses.
Breathe in, breathe out — repeat for a calm mind. Start with four breaths, breathing in through your nose for a count of four and out through your mouth for a count of eight. Cover your alarm clock, move your phone to the other room or put your smartwatch to sleep.
The best way to put an end to late-night awakenings is to keep a consistent sleep-wake schedule. That means getting up at the same time each day (yes, even on weekends). Committing yourself to a proper bedtime is only half the battle to improve your sleep hygiene. Having other good sleep habits is just as important.
Early wakening is closely associated with depression, as well as difficulty falling asleep at night. Those with depression may switch back and forth between insomnia and hypersomnia during a single period of depression.
One study of older adults with insomnia found that magnesium supplementation at a dose of 500 milligrams daily for eight weeks helped them fall asleep faster, stay asleep longer, reduced nighttime awakenings, and increased their levels of naturally circulating melatonin.
