According to a study published in the International Journal of Environmental Research and Public Health, milk and dairy products may promote good sleep quality. The practice of eating cookies and milk before bed is a tradition with both scientific backing and psychological roots, explaining why so many find it a comforting pre-sleep ritual.

According to the Sleep Foundation, nearly 90% of US adults consume caffeine daily, but its effects vary dramatically among individuals.

Millions of people worldwide consume coffee daily for a kickstart, but the energy they feel isn't what it seems.

Approximately 1 to 3 pounds of your body weight can vanish overnight, a phenomenon that perplexes many who step on the scale each morning. The answer to where does body weight go overnight is not a result of magical fat-burning but a series of natural and temporary physiological processes.

A single roasted coffee bean contains only about 6-12 milligrams of caffeine, a tiny fraction of the average 96 milligrams found in a brewed cup.

Four shots of espresso contain approximately 258 milligrams of caffeine, well within the 400 mg daily limit recommended for most healthy adults. However, whether this dose will effectively wake you up depends heavily on individual factors like tolerance, body weight, and genetics.
