Dr. Aurelio Rojas, a cardiologist, has highlighted the benefits of the night shower, assuring that it is one of the best scientific tricks for longevity. According to the doctor, this simple habit not only decreases the time needed to fall asleep but also improves memory, the immune system, and mood.
“"After a warm shower, the blood vessels in our skin dilate, our body releases heat, and the core temperature drops. This natural drop activates the release of melatonin, which will help you start resting and counteract cortisol, the stress hormone."
This recommendation has scientific backing. A systematic review of 17 studies published in the journal Sleep Medicine Reviews concluded that a warm bath or shower (around 40 degrees Celsius) taken one to two hours before bed shortens the time it takes to fall asleep and increases sleep efficiency.
The key effect lies in the cooling process after the shower. Slightly raising the body temperature and allowing it to gradually drop sends biological signals to the body to initiate rest. To put this into practice, it is advised that the water be around 40 degrees and to avoid going to sleep immediately afterward.
