According to statistics, one in eight adults on the planet takes sleeping pills but continues to suffer from insomnia. Scientists analyzed the most popular sleep aids and came to some disappointing conclusions. It turned out that the effect of melatonin is indistinguishable from a regular 'dummy' (placebo) in 50% of cases. The body quickly becomes accustomed to the artificial hormone and stops producing its own. Magnesium, which is considered a good remedy for stress, only brings real benefits to those whose sleep is disrupted due to muscle cramps. The effectiveness of oil with hemp extract (CBD), after which marketers promise instant relaxation, has not been proven. Experts note that the main enemies of quality sleep are chronic stress, the 'blue light' from gadgets that blocks natural sleep mechanisms, and the lack of a clear schedule. Stable wake-up times and physical activity, which cost nothing, positively influence sleep.
