The Role of Selenium in Enhancing Sleep: What You Need to Know

Sleep is a fundamental aspect of our well-being, yet it often eludes many of us. From tossing and turning to waking up feeling groggy, the struggle to get a good night’s rest can be frustrating. But what if a simple mineral could help? Selenium, a trace element found in various foods, has been gaining attention for its potential to enhance sleep quality.

In this article, we’ll delve into the science behind selenium and uncover how it can play a crucial role in helping you achieve better, more restful sleep.

What Is Selenium

Selenium is a trace mineral, which means that the body only needs a small amount of it. It is found naturally in foods or as a supplement. This mineral is an essential component of various enzymes and proteins, called selenoproteins, that help to make DNA and protect against cell damage and infections.

These proteins are also involved in reproduction and the metabolism of thyroid hormones. Most selenium in the body is stored in muscle tissue, although the thyroid gland holds the highest concentration of selenium due to various selenoproteins that assist with thyroid function.

Food Sources Of Selenium

The amount of selenium in foods can vary widely depending on the selenium content of the soil in which it is grown. Soil content varies widely by region. Plant foods obtain selenium from soil, which will then affect the amount of selenium in animals eating those plants. Protein foods from animals are generally good sources of selenium.

Seafood, organ meats, and Brazil nuts are the foods highest in selenium although Americans obtain most of their selenium from everyday staples, like breads, cereals, poultry, red meat, and eggs.

• Brazil nuts
• Fin fish and shellfish
• Beef
• Turkey
• Chicken
• Fortified cereals
• Whole-wheat bread
• Beans, lentils

What Else Can Selenium Do For The Body?

In addition to helping with sleep, selenium has other health properties – it helps in the process of DNA replication, reproduction and thyroid hormone metabolism and protection against infections.

Signs of selenium deficiency include, but are not limited to: hair loss, changes in the shape of the nails and skin, itchy scalp or dandruff, extreme fatigue, “brain fog”, muscle weakness, a weak immune system, as well as fertility problems.

What About Supplements?

Selenium supplements are promoted to offer several benefits, including boosting immune function, improving hair and nail health, and supporting a healthy thyroid. They are sometimes combined with other antioxidant vitamins such as vitamin E or C. These supplements usually contain between 100-400 micrograms of selenium per dose (the Tolerable Upper intake Level is 400 micrograms). However, if a person is not at high risk for a deficiency, there is no evidence that taking a higher amount of selenium promotes the health benefits shown on these supplement labels.

In conclusion, selenium’s role in enhancing sleep is a fascinating area of research that offers promising insights. While it’s not a magic bullet, incorporating selenium-rich foods into your diet or considering supplements under the guidance of a healthcare professional can be a valuable step towards improving your sleep quality.

Remember, a good night’s sleep is essential for your overall health and well-being, and every little bit helps. So, the next time you’re planning your meals, don’t forget to include some selenium-rich options to support your journey to better sleep.
