Do you tend to eat at irregular hours due to frequent late nights at the office or because you travel often?
If so you will know the value of a good night's sleep and the pain of not receiving any despite being exhausted.
The main reason is because erratic sleeping times throw your circadian clock out of whack.
Your cyclical internal rhythms known as your circadian clock rely on cues from light and other environmental factors to regulate sleepiness, hunger, metabolism and immune system function.
A new study published in the journal Cell Reports suggests that we can help return our circadian clocks to normal by eating specific foods and specific times.
Researchers from Japan found the connection between diet and circadian rhythm mainly centred on producing enough insulin - the hormone which helps you absorb glucose into your blood stream and evidently, can make you feel tired in the process.
Certain foods are known to trigger insulin secretion more effectively than others and study author Dr Makoto Akashi particularly recommends carbohydrates such as pasta, rice and potatoes in a report by Science Daily.
The research team from Yamaguchi University suggest that you reduce these sleep-inducing ingredients in the morning when you know you need to be more alert. So, steer clear of carb-heavy breakfast foods and instead opt for lean proteins, veggies, fruit and whole grains.
Getting your circadian clock back in sync through food may actually drive better digestion, metabolism and overall wellness, helping us to avoid lifestyle diseases such as type 1 diabetes.
Unfortunately, while changing your eating habits might assist you if you're in good health, those with insulin-resistant diseases such as type 2 diabetes might need to try other avenues to get to sleep.
And while your diet might help you get to sleep easier, other lifestyle habits such as sitting in front of a bright computer or TV screen just before bed can still mess with your circadian rhythm.
