If you're struggling to drop off to sleep at night, this might be the solution you're looking for.
US researchers from the University of Austin have found that taking a hot bath one or two hours before bedtime can significantly improve your quality of sleep.
In the study of over 5000 people published in the journal Sleep Medicine Reviews, researchers found that the rapid heating then cooling of your core body temperature aids the natural circadian process.
"The temperature cycle leads the sleep cycle and is an essential factor in achieving rapid sleep onset and high-efficiency sleep," the study reads.
"[This] will aid and increase one's chances of not only falling asleep quickly but also of experiencing better quality sleep."
The water reportedly needs to be a temperature of around 40-42 degrees celsius for optimal results.
"Warm baths and showers stimulate the body's thermoregulatory system, causing a marked increase in the circulation of blood from the internal core of the body to the peripheral sites of the hands and feet," the study reads.
Research last year showed that eating eggs was another effective way of dropping off to sleep, due to the amino acid tryptophan.
