What complications can bad Sleep Health lead to?

Bad sleep health can cause many problems that affect both our bodies and minds. Here are some of the major complications:

  • Heart and Metabolic Issues: Not getting enough sleep is closely linked to serious heart problems, like high blood pressure, heart disease, and stroke. People who sleep poorly are also more likely to become obese or develop type 2 diabetes. Lack of sleep can affect how our bodies control certain functions and can increase inflammation, making these health issues worse.
  • Mental Health Problems: Sleep troubles are often related to mental health disorders, including depression and anxiety. When people don’t sleep well or don’t get enough sleep, they are at a higher risk of experiencing these issues.
  • Cognitive Problems: Chronic sleep deprivation can hurt our thinking abilities, memory, and overall brain health. It is also linked to a higher risk of brain diseases like Alzheimer’s.
  • Quality of Life and Daily Functioning: Poor sleep can make it hard to do daily tasks, both at work and home, reducing our overall quality of life. Feeling very sleepy during the day can make it harder to stay alert and can lead to more accidents.
  • Increased Risk of Death: Not sleeping well is associated with a higher risk of dying from other causes. Studies show that irregular sleep patterns and not getting enough sleep can lead to more chronic diseases and even affect life expectancy.

Impact of bad sleep health on mortality

Bad sleep can have serious effects on our health, including increasing the risk of dying from various causes, heart problems, and certain types of cancer.

  • All-Cause Mortality: Not sleeping well—like having irregular sleep patterns or not getting enough sleep—can lead to a higher chance of dying from any cause. A study published in the Journal of Internal Medicine found that people who followed healthy sleep habits had a 4-11% lower risk of dying from all causes. 
  • Cardiovascular Mortality: Poor sleep health is also connected to a greater risk of dying from heart-related issues. The same study in the Journal of Internal Medicine found that people with healthy sleep habits had a 24-42% lower risk of dying from heart problems. Other studies have found similar findings.

Cancer-Specific Mortality: Not sleeping well can raise the risk of dying from cancer, too. The study in the Journal of Internal Medicine reported that those with healthy sleep patterns had a lower risk of cancer mortality. 

Impact of bad sleep health on partners

When one partner has poor sleep health, it can really affect the other partner’s sleep, emotions, and the overall relationship.

  • Sleep Disturbances: If one partner has sleep issues, like obstructive sleep apnea (OSA), the other partner may have trouble sleeping too. They might deal with loud snoring and frequent wakeups, which leads to poor sleep quality and daytime tiredness.
  • Emotional and Psychological Effects: Poor sleep in one partner can cause emotional stress for the other. This can include feelings of anxiety, depression, and irritability. For example, partners of people with chronic pain who don’t sleep well often report feeling angrier and more upset in the morning.
  • Relationship Quality: Sleep problems can create tension in the relationship. Partners of people with insomnia or other sleep disorders often feel more conflict and less satisfaction in their relationship. Poor sleep can also make conflicts between partners worse, leading to more arguments.
  • Physical Health: The physical health of the partner can also suffer. For instance, partners of people with REM sleep behavior disorder (RBD) may get injured during sleep and experience insomnia, anxiety, and depression themselves, which can lower their quality of life.
  • Support and Treatment: If the partner with sleep issues receives proper treatment, like using a CPAP machine for OSA, it can help both partners sleep better and feel happier. Working together on the treatment can lead to better results for both.

In summary, when one partner has bad sleep health, it can lead to sleep troubles, emotional stress, relationship problems, and health issues for the other partner. Addressing these problems with effective education, treatment and support can help reduce these negative effect
