Many people are affected by occasional to more frequent sleep disorders. There are many reasons for this. Researchers have now established a link between sleep quality and vitamin D balance. While a balanced diet provides you with the most important vitamins and minerals, vitamin D plays a special role, as much of it is gained from our exposure to the sun. As Australians, we have been taught to slip, slop and slap to protect ourselves from the sun, which has seen rates of Vitamin D deficiency increase.

What is vitamin D?

Vitamin D refers to a group of fat-soluble vitamins that perform different functions in the body. The best known is bone mineralization. For this purpose, calcium and phosphate are absorbed from the intestine and made available to our bones. Vitamin D also plays an important role in healthy sleep. A deficiency can ‘increase the risk of sleep disorders and is associated with sleep difficulties, shorter sleep duration, and nocturnal awakenings’ (Vitamin D Supplementation and Sleep: A Systematic Review and Meta-Analysis of Intervention Studies, Myriam Abhoud, 2022). In addition, vitamin D is needed for the formation of serotonin. This is a neurotransmitter that regulates sleep and is involved in melatonin production.

How does the body make vitamin D?

Among vitamins, vitamin D has a special position, because under certain circumstances it can be produced by our body itself. Decisive for the body to be able to form vitamin D is the UV-B radiation intensity in sunlight. If this is too low, the body’s own vitamin D production comes to a standstill.

Should I supplement vitamin D?

It is estimated that over 30% of Australian adults suffer from a vitamin D deficiency. It’s important that such a deficiency is diagnosed by a doctor. If a deficiency is present, vitamin D supplementation is recommended. However, you should only take dietary supplements on the advice of your doctor, as an overdose can also cause unwanted side effects. If you suffer from trouble sleeping or feel tired and lacking energy, you should have your vitamin D status checked.

This is how you get a good night’s sleep:

In addition to vitamin deficiencies, there are many other causes that can negatively affect your sleep. Our tips can help you prevent insomnia and wake up feeling rested.

  • Regular bedtimes: Regular and consistent bedtimes and wake-up times help your body get to sleep more easily
  • Reduce stress: Stress is a common trigger for sleep problems. Relaxation techniques or conscious switching off can help the body, mind, and soul to switch off and relax
  • Caffeine: Avoid caffeine, especially in the afternoon and evening, as this can negatively affect your sleep quality and prevent you from falling asleep
  • Proper sleeping environment: Mattresses and pillows have a significant influence on sleep and should be changed and cleaned regularly



Our sleep is controlled by many, often very complex factors. Micronutrients in general and vitamin D in particular have an important influence on healthy sleep. If after consulting your doctor you find that you have a Vitamin D deficiency, take a high-quality dietary supplement, if recommended by your doctor.
