Most people get excited when it rains at night. That joy comes from the belief that the rain will give them a good night’s rest. Scientifically speaking, there could be some truth to that.
Different things in your sleep environment can influence the quality of sleep you get, and this includes sounds.
Adding sounds to your sleeping environment is proven to improve your sleep quality. When it comes to the sounds of rain, different people find it relaxing for a variety of reasons.
Why Does Rain Make You Sleepy?
Whether you’re at home or work, you might feel more sluggish than usual when it rains. The rain may leave you feeling like you should put everything to the side and not worry about a thing.
The number one reason why you may feel a little more sluggish or too relaxed when it rains is because of the air pressure. Air pressure decreases when it rains. Along with the low air pressure, the air is also filled with a lot of water vapor.
The combination of low air pressure and water vapor inadvertently lowers the oxygen levels in the air, making your brain feel tired. When it rains, negative ions are released and that leads to people feeling more relaxed and comfortable.
High humidity also has a huge impact on how tired you feel when it rains. At this time, your body is fighting to maintain homeostasis and this can lead to you feeling tired and wanting to rest.
Other reasons rain sounds make you sleepy include:
The Rhythmic Sound
The continual, rhythmic hum of pounding rain is surprisingly relaxing. It’s a calming, non-threatening noise that is like a massage for the brain.
It’s no surprise that many meditation and relaxation videos incorporate rain sounds. Nature sounds, including rain, have even been found in a study to reduce anxiety in patients undergoing coronary artery surgery.
Increased Melatonin Secretion
As the light disappears at night and your body gets ready to sleep, it produces a hormone called melatonin. This causes you to become sleepy, and your brain starts to shut down for rest.
When it rains, the sky can often become overcast and dark, meaning your body might start secreting melatonin earlier in the day, causing you to feel much more tired.
Restricted Outdoor Activity
Another reason why rain makes you feel sleepy is that there isn’t much to do on a wet, overcast, cold day. If the rain is pelting down, you might cancel your outdoor activities and end up staying indoors.
Being so inactive can make you feel more tired than you usually would. This might end up with you napping on the sofa to the rhythmic rain sounds.
