We discovered that early risers are more physically fit and more physically active than night owls, who are more inactive during the day.
An uphill challenge was used to measure the participants' aerobic fitness levels. The slope was increased by 2.5% every two minutes until the individual was completely exhausted.
Researchers discovered that compared to night owls, early birds consume more fat as energy during both rest and exercise. Additionally, early birds were more insulin sensitive. Contrarily, night owls are insulin resistant, which means their systems prefer carbs to fats as an energy source and need more insulin to drop blood glucose levels.
Because it suggests a higher risk of type 2 diabetes and/or heart disease, this group's reduced capacity to respond to insulin to enhance fuel usage may be detrimental. Investigation is still needed to determine the exact reason for this difference in metabolic preference between night owls and early risers.
New Jersey's Rutgers University's senior author, Professor Steven Malin, said: Because "night owls" and "early birds" have different rates of fat metabolism, our circadian rhythm may have an effect on how our bodies utilize insulin. Our health is greatly impacted by how responsive or poorly we react to the insulin hormone.
Our knowledge of how our body's circadian rhythms affect our health is now improved by this discovery. We propose that chronotype might be utilised as a factor to predict a person's risk for disease because it appears to affect our metabolism and hormone function.
More investigation is required to determine whether exercising earlier in the day has better health advantages by examining the relationship between chronotype, exercise, and metabolic adaption.
An urge to stay up late may decrease your body's ability to burn fat and raise your risk of type 2 diabetes and heart disease, according to a recent research.
