Role of Genetics in Sleep Disorders (2024)

You have been trying everything to improve your sleep—white noise, mattress changes, healthy routines—but nothing seems to be helping you with your long-term sleep disorders. There's nothing left to blame for restless nights, but have you ever thought about the possibility that your genetics could be the reason for your sleep disorders?

The idea that genetics play a role in sleep disorders could seem absurd, but it is accurate. Sleep problems are closely related to the fact that genes have always been important in every aspect of human existence, from appearance to behavior. In this blog, we’ll explore whether sleep disorders can be passed on and how genetics can affect sleep.

What are Sleep Disorders?

First, let's understand what sleep disorders are. Sleep disorders (or sleep-wake disorders) are difficulties with the quality, timing, and quantity of sleep that result in daytime stress and problems in functioning. Common sleep disorders include insomnia (trouble falling or staying asleep), sleep apnea (breathing interruptions during sleep), and restless legs syndrome (uncomfortable sensations in the legs).

The Genetic Connection

Have you ever noticed symptoms or something similar to your sleep condition in your family, it's because you share the same genes with them. Genes are tiny portions of DNA found inside the cells of all living beings. Genes contain the information passed down from parents to children via chromosomes.

These genes are responsible for children inheriting characteristics from their parents or ancestors, such as hair, eyes, and facial features. According to studies, genetic factors play an important impact in both good sleep patterns and sleep disorders such as insomnia, restless legs syndrome, and obstructive sleep apnea.

Certain genetic variants have been shown in studies to have been possibly linked to insomnia. The production of neurotransmitters that regulate sleep as well as the control of sleep-wake cycles can be impacted by these genes.

Also, there is evidence that someone's genetic makeup could make them have restless legs syndrome. The brain's dopamine levels can be affected by specific gene variants, which can result in an insatiable drive to move one's legs.

How Genetics Interact with other Factors

While genetics can influence our likelihood of developing a sleep disorder, it's important to note that other factors also play a role. Lifestyle choices, such as diet and exercise, as well as environmental factors like stress and sleep environment, can all impact our sleep quality.

You can follow these tips to sleep better at night:

  • Maintain a regular sleep routine, even on the weekends. Set a bedtime and wake-up time.
  • Do something relaxing to help your body wind down before bed, like reading a book away from bright lights or putting electronics away early.
  • Use a memory foam pillow at night.
  • Avoid taking naps, particularly in the afternoon.
  • Every day, work out for at least 30 min.
  • Take note of your sleeping environment—a cool, dark, and quiet space is ideal—as well as the quality of your mattress and pillow.
  • Avoid caffeine, alcohol, and large meals in the evening.

If you feel you have a sleep condition or if bad sleep runs in your family, you should visit a healthcare expert. They can assess your symptoms, review your family history, and suggest relevant remedies.

Conclusion

Genetics is not the main cause of sleep disorders, but it plays an important role. By knowing what is the link between gentitis and sleep disorders, you can find better ways to deal with it and can improve your sleep quality.

If you are experiencing a sleep disorder, there are things you can try to improve the situation. One modest alteration that can have a significant impact is replacing your standard pillow with a memory foam pillow. These have been shown to be useful for sleep disorders and improve your sleep quality. A memory foam pillow can conform to the contour of your head and neck, allowing you to sleep in a more comfortable posture.
