It is no secret that sleep is an essential part of our lives. It gives our bodies a chance to rest, our brains an opportunity to consolidate memories, and our immune systems to work much better. But how is your body programmed to know it is time for some shuteye? There is a very precise internal communication system in your body that directs these sleep-related messages. In this blog, we’ll explore this system in detail.
Body Signals of Sleepiness
Our bodies are designed in a way that they push us to sleep with various natural signals:
Physiological Changes: As the evening approaches, our body restarts the production of melatonin, a hormone that controls our sleep-wake cycle. This increase in melatonin is what gives you the urge to sleep and kickstarts the body's processes for it. Furthermore, your core body temperature starts to decline in the evening hours, which thus helps you drift off to sleep.
Physical Signs: There’s the most evident one: you start feeling tired. However, there are some less obvious indicators as well. It is common to have constant yawning, sluggishness, and weak muscles to show that your body is getting ready for sleep.
Mental Changes: Have you ever experienced a sluggish or hazy brain after a long day at work?
These are the telltale symptoms of sleep deprivation . Foggy thinking, forgetfulness and diminished alertness can be the brain’s message that you need rest.
Behavioral Cues: Do you often get more annoyed and snappy as the day comes to an end? These mood changes can also be the first indicators of sleepiness. People also crave sugar at this time, as their bodies try to get a quick energy boost with sugar while they actually need sleep instead.
The Importance of Listening to Sleep Signals
Overlooking the signs of sleepiness could have serious consequences. Inadequate sleep can lead to altered performance levels, compromised brain function and heightened accident risk. When we don’t prioritize sleep, we compromise our ability to perform to the best of our ability, both physically and mentally.
Studies have demonstrated that inadequate sleep could lead to numerous health issues, such as obesity, diabetes, heart disease and weakened immunity defenses. Over time, this deprivation can affect our quality of life due to so many health complications.
Tips for Promoting Healthy Sleep Habits
So, how can you ensure you're listening to your body's sleep signals? Here are some tips:
- Set a Sleep Schedule: Go to sleep and wake up at consistent times every day without fail. You should follow this schedule even on the weekends. This makes your body adapt to a healthy sleeping pattern and regulates your body's natural sleep-wake cycle.
- Develop a Relaxing Bedtime Routine: The time before sleeping should be relaxing. So avoid stimulating activities like watching TV, binge-watching, or scrolling on social media right before you sleep. It is best to avoid screens at this time.
- Create a Better Sleep Environment: Your bedroom should be cool, dark, and quiet. This helps your body get a deeper and more relaxing sleep.
