The Relationship between CBD and Sleep: Exploring the Potential Impact of CBD on Sleep Quality

Effects of CBD on Sleep Quality and Immune System

In an 8-week controlled study, researchers from the Department of Physiology, Nutrition, and Food Science at North Texas University in Greeley, USA, investigated the potential benefits of CBD (cannabidiol) on sleep quality and immune system enhancement, specifically focusing on natural killer cells. Here are the key findings:

1. Study Design:

   • The study involved 28 healthy volunteers who were randomly divided into two groups: one receiving CBD orally at a dosage of 50 mg, and the other receiving a placebo.

2. Immune System Response:

   • After the 8-week trial, the group receiving CBD showed significant improvements in the quality of sleep, as measured by standardized sleep quality and Natural Killer (NK) cell activity assessments.
   • There were no significant changes observed in body weight or fat percentage.

3. Psychological and Physiological Parameters:

   • No notable differences were found between the CBD group and the placebo group in terms of mental health, sleep duration, or immune system modulation.
   • Additionally, there were no observed changes in immune response attributed to the experiment.

These results suggest that CBD may play a role in improving sleep quality and enhancing the activity of natural killer cells without affecting overall health, mental well-being, sleep duration, or immune function modulation. However, further research is needed to validate and expand upon these findings, especially regarding the long-term effects of CBD use.
