Do you feel sleepy on rainy days? If the answer is yes, you are not alone. But do you know why?
One of the reasons is that there is little sunshine on rainy days. Our brain will have less serotonin(血清素) and more melatonin(褪黑素) if there is not enough sunlight. Serotonin helps us feel good and energetic, while melatonin makes us feel sleepy. As a result, we may want to go to sleep and even feel a bit sad when it is rainy.
The humidity of a rainy day is another reason. As it rains, the air becomes wetter than usual. It's more difficult for our sweat(汗水) to dry in weather like this, so our body has to work harder to stay cool. This can make us feel tired.
Moreover, the sound of rain, a type of pink noise, will make us feel sleepy too. Like white noise, pink noise includes all the sound frequencies(频率) humans can hear, but it has fewer high frequencies than white noise. This makes pink noise sound softer. Studies show that people's brain waves(脑电波) will become fewer when they hear pink noise, so they will fall asleep more easily.
Then what can you do if you don't like that sleepy feeling? Well, you can get as much natural light as possible and keep yourself busy. Also, you can use a machine to make your room dry. In this way, you won't feel sleepy any more.
