Cortisol is the primary stress hormone that can increase your blood pressure and anxiety. Your body releases it in the morning after it sees sunlight to tell it to wake up, and this release activates the sympathetic nervous system. It is important to keep your cortisol level in control, or you could be subject to insomnia and elevated stress.

What Happens if Cortisol is Not Regulated?

Cortisol isn't necessarily bad on its own. It is needed in times of stress to prepare your body for what might come next. It is only chronically high levels of stress hormones that could negatively affect you. Coincidentally, it is the blue light from the sun that stimulates cortisol release, and the same effect is experienced when looking at the blue light from electronic screens. This means that electronic screens are almost directly related to higher cortisol levels and, therefore, sleep issues and insomnia.

Reishi Mushrooms boost the function of adrenal glands because it positively affects the HPA. With the improvement in adrenal glands, you can experience better cortisol regulation, which means more cortisol in times of stress, but less cortisol release during non-acute stress.

Additionally, Reishi mushroom's adaptogenic property is effective to lower stress in the body, which means a dip in cortisol level and easing of anxiety as well.

Reishi Mushrooms are a natural supplement that may help your body regulate cortisol release.


Reishi mushroom is available in different forms aside from the raw or dried components, such as powders or capsules. You can take Reishi mushrooms before bed or even in the morning with a hot cup of coffee. The effects are not short-term, and so they should carry over the same benefits regardless of when you choose to take this functional mushroom.
