Why do you feel sleepy before rain? 😴
There are several reasons for that. The first one is the lack of oxygen in the blood. When atmospheric pressure drops, our body lowers blood pressure and reduces the heart rate. This leads to a decrease in the concentration of oxygen in the blood, affecting the activity of the nervous tissue in the brain, which also decreases. As a result, sleepiness sets in.
The second reason is related to the level of melatonin, the "night hormone." The appearance of the sun blocks the production of melatonin in the body, while overcast skies disrupt the body's biological clock - the body simply doesn't understand why it's being forced to stay awake when it's dark outside. 🌧️
