Not getting enough sleep is associated with various health problems, such as an increased risk of cardiovascular diseases, hypertension, heart attack, diabetes, suppressed immune system, obesity, dementia, and suicide. Sleep deprivation is also related to various workplace issues, such as impaired concentration, decreased productivity, a high risk of errors and accidents. Many people with chronic insomnia frequently resort to self-medication with alcohol or substance abuse, both of which will not lead to a long-term solution.
With worsened daytime functioning, the longer the problem with insomnia, the higher likelihood of individuals descending a negative spiral that would worsen insomnia. For example, those who struggle to fall asleep quickly at night might worry about excessive fatigue and decreased performance the next day. This heightens the anxiety levels and makes it more difficult to fall asleep. Over time, when the functioning levels are affected significantly during the day, the stress and anxiety increase, thereby impacting the ability to fall asleep, leading to a negative spiral.
