The Science of Sleep: A Brief Guide on How to Sleep Better Every Night

Metabolical Health

When we sleep 5.5 hours per night instead of 8.5 hours per night (recommended is 8 hours), we tend to burn more energy using carbs and protein, instead of fat. This can result in fat gain and muscle loss. Also, insufficient sleep or abnormal sleep cycles can increase the risk of diabetes and heart disease.

Keep in sync with your body’s natural sleep-wake cycle
  • Try to go to sleep and get up at the same time every day;
  • Avoid sleeping in, even on weekends;
  • Limit naps to 15 to 20 minutes in the early afternoon;
Melatonin

Is a naturally occurring hormone controlled by light exposure that helps regulate your sleep-wake cycle. 

Your brain secretes more melatonin when it’s dark, making you sleepy, and less when it’s light, making you more alert. 

However, many aspects of modern life can alter your body’s production of melatonin and shift your circadian rhythm

Influence exposure to ligh

During the day:

  • Expose yourself to bright sunlight in the morning. 
  • Spend more time outside during daylight. 
  • Let as much natural light into your home or workspace as possible.

At night:

  • Avoid bright screens within 1-2 hours of your bedtime.
  • Say no to late-night television.
  • Don’t read with backlit devices. 
  • When it’s time to sleep, make sure the room is dark.
  • Keep the lights down if you get up during the night.
Sleep deprivation

Get through sleep deprivation:
  • Stabilize your blood sugar, by eating hearty food (protein and fat) more often.
  • Reduce refined carbs and increase fats and proteins.
  • B-complex vitamin supplements can give you an immediate boost in alertness and mental clarity.
  • Soak in an Epsom salt bath - might even help you get enough energy to exercise the next day.
  • Drink more water than you usually do to help compensate.
  • Exercise is the single best way to “take out the trash” in your body, and after staying up more hours than you should.
Your body needs dark too
Your body needs dark too

While we are starting to pay attention to how important sleep is, the need for dark is still mostly ignored.

Being exposed to regular patterns of light and dark regulates our circadian ...

Our sleep and wake patterns

On its own, the circadian rhythm takes almost 24 hours. Our bodies rely on the Sun to reset this cycle and keep it at 24 hours, the length of our days. Light and the dark are important signals for the cycle.

During the night, body temperature drops, metabolism slows, and the hormone melatonin rises dramatically. When the Sun comes up in the morning, melatonin has already started falling, and you wake up.

Our bodies in the dark

During the dark, levels of the hormone leptin (hunger control), go up. This means we do not feel hungry while low levels make us hungry.

Ans research found that sleep disruption and turning on lights lowers leptin levels which makes people hungry in the middle of the night.
