Someone who frequently falls ill usually has a weak immune system. One of the factors that weaken the immune system is irregular sleep patterns. This is because sleep time apparently correlates with the immune system.

To improve the immune system, it is not enough to just have regular sleep and maintain a healthy diet, you can try these 4 types of herbal drinks before bed. The following drinks have benefits to make sleep more sound, thus increasing the immune system.

The clearest sign that can be seen when the immune system weakens is frequent illness. In addition, difficulty in completing daily tasks, stomach problems, high levels of stress, and frequent headaches are also indications of a weak immune system.

According to information from Mayo Health Clinic, the immune system in the body produces a type of protein called cytokines. This protein has an important role in the process of healing inflammation within the body.

When you don't get enough sleep, the production of this protein can decrease, which ultimately affects our immune system levels. Therefore, getting a good night's sleep plays a very important role in boosting our immune system.

According to research from Harvard Health, ginger has the ability to reduce inflammation and improve digestion. If you are not used to consuming this, you can add lemon juice to ginger tea to enhance nutrition and immune system.

Other herbal tea options that you can consume before bed are peppermint tea. The National Institutes of Health (NIH) stated that peppermint has antivirus and antimicrobial properties that make it an immune system booster.

In addition, peppermint also has a calming effect on the mind and helps to sleep more soundly. By making a cup of peppermint tea before bed, you will experience better sleep quality and your immune system will also be maintained.
