We often attribute fatigue to or stress. However, American researchers have uncovered a potential biological reason for excessive daytime sleepiness. It’s linked to certain molecules in the blood, which may determine whether you feel energetic throughout the day or struggle with a constant urge to nap, reports Daily Mail.
Fatigue Has Its “Biological Roots”
Sleep experts from Brigham Women’s Hospital in Boston surveyed and collected blood samples from over 6,000 people, identifying seven metabolites—substances formed during metabolism. These metabolites influence the tendency toward daytime sleepiness.
- Some compounds, such as tyramine (found in fermented and overripe foods), were linked to poorer sleep quality and increased fatigue.
- Others, on the contrary, had a protective effect. This is particularly true for omega-3 and omega-6 fatty acids, which are found in fish, , and egg yolks. People with higher levels of these substances reported less excessive sleepiness.
The Dangers of Daytime Sleepiness
Excessive fatigue affects not only productivity and mood but also increases the risk of obesity, , and cardiovascular diseases. It is estimated that up to one-third of the adult population in the U.S. suffers from it. Additionally, this condition may have different mechanisms in men and women, as hormones play a significant role.
Can Dietary Changes Help?
Researchers emphasize that while further clinical trials are needed, initial results suggest that a proper diet may reduce the risk of daytime sleepiness. Specifically, regularly consuming fatty fish, nuts, and other sources of omega acids could serve as a natural “defender” against fatigue.
A Step Toward a More Energetic Day
Scientists are confident that we underestimate the impact of nutrition on sleep quality and alertness. By changing our eating habits, we can not only gain more energy but also protect our hearts and brains. Sometimes, the key to an energetic day lies not in a cup of coffee, but in a plate of fried fish or a handful of nuts.
