First, read the English article below.

If your cortisol levels are low, but not low enough to require hormone replacement therapy, it's still important to keep your life as low-stress as possible. Learning to manage and reduce stress in your life will allow cortisol to gradually increase in your system instead of being produced all at once in high-pressure situations. The more stress you have, the faster your cortisol will get depleted. Try stress management techniques like journal writing, yoga or meditation to teach your body to produce cortisol regularly and maintain healthy levels. The body naturally produces cortisol during the hours when you're sleeping. Get 6-to-8 hours of sleep per night and try to go to sleep around the same time each evening. Create a peaceful environment with no light or noise to get deep sleep and aid cortisol increase. Foods high sugar and refined flour can cause cortisol levels to spike or drop to unhealthy levels. Eat plenty of whole grains, fruits and vegetables to help raise cortisol levels to a healthy amount. Grapefruit and citrus break down enzymes that limit cortisol production. Adding grapefruit to your diet on a regular basis can help your adrenal glands boost cortisol production. Licorice contains glycyrrhizin, which inhibits the enzyme in your body that breaks down cortisol. Inactivating this enzyme will help you gradually raise cortisol levels. Licorice is considered a very useful substance for boosting cortisol.  Look for licorice herb supplements in tablet or capsule form at a vitamin or health food and supplement store. Avoid using licorice candy as a supplement. It doesn't contain high enough amounts of glycyrrhizin to be useful. This can help increase your energy if you are facing fatigue. Natural iron supplements can be taken if you need an increase in energy as well.
