Insomnia refers to a medical condition in which it's difficult to fall asleep and stay asleep. MedlinePlus says this is specifically classified as insomnia when the pattern of sleep habits occurs for at least one month. Specific insomnia symptoms include waking up frequently throughout the night and feeling tired during the day. Causes of insomnia can be managed.
Depression
Depression refers to a mental illness that affects a person's physical and emotional state. Depression is associated with such symptoms as insomnia, sadness, hopelessness and fatigue. The University of Maryland Medical Center says depression can also lead to trouble concentrating, decreased libido (sex drive), changes in appetite and thoughts of suicide. In some instances, depression can also lead to restlessness, agitation, guilt and irritability.
The exact cause for depression is unknown, but its risk factors include social isolation, heredity, taking medications and suffering from such diseases as cancer or a heart attack. Treating depression involves eating a healthy diet, exercising daily and taking antidepressant medications such as fluvoxamine, escitalopram or citalopram. Counseling, combined with these medications, is a necessary part of treating depression.
Stress
Stress refers to a normal psychological reaction to tension in the environment. Stress is typically associated with insomnia, an increased heart rate, increased blood pressure, fast breathing and trouble swallowing. The University of Maryland Medical Center also says stress can lead to dry mouth, cool and clammy skin and trouble talking.
Stress leads to insomnia because the body begins to release a substance called neuropeptide S from the body. This reduces sleep, and increases anxiety and tension. Also, the body begins to release other chemicals called catecholamines.
Treating stress involves exercising each day, eating a healthy diet and reducing stress through relaxation techniques such as deep breathing exercises and yoga. Sometimes, seeking the help of a mental professional may be beneficial. He can help to explore stress triggers and how to cope with them specifically.
Anxiety
FamilyDoctor.org of the American Academy of Family Physicians (AAFP) says that anxiety refers to a feeling of worry, fear or panic because of a certain situation or object. Anxiety symptoms include insomnia, muscle tension, dizziness, shortness of breath and a fast heartbeat. This condition can also lead to irritability and trouble concentrating. Sometimes, anxiety can turn into panic and lead to such physical symptoms as chest pain, a racing pulse, hot flashes and trembling.
A chemical imbalance or a memory of a particularly stressful situation can trigger anxiety.
Treating anxiety involves sleeping well, eating a healthy diet, avoiding caffeine and controlling worry. Sometimes it may help to consult a medical professional. In some instances, medication can be prescribed to manage anxiety symptoms.
