Experts agree that regularly exposing yourself to volumes higher than 60 decibels can cause hearing damage.
Keep reading to learn about how sleeping with headphones impacts your health. There’s nothing wrong with relying on headphones to wind down before bed, but falling asleep with them on poses several health risks. Calming sounds, like piano music and white noise, can also help people relax before falling asleep by lowering the heart rate and alleviating stress. “Make sure that you start dimming your lights at least an hour or two before you go to bed to prepare your environment for sleep.Most people have a rough time sleeping in noisy environments, and headphones are a popular way to block outside noise. “I think the strength of the evidence is that you should clearly pay attention to the light in your bedroom,” she said. What advice would Zee give people based on her study and existing research in the field? Close your blinds and curtains, turn off all the lights, and consider using a sleep mask. The study was published Monday in the journal of the Proceedings of the National Academy of Sciences. The light was not bright enough, however, to lower levels of melatonin in the body, Zee added. In addition, heart rate was higher, insulin resistance rose, and the sympathetic (fight or flight) and parasympathetic (rest and relax) nervous systems were unbalanced, which has been linked to higher blood pressure in healthy people.
Yet even that tiny amount of light created a deficit of slow wave and rapid eye movement sleep, the stages of slumber in which most cellular renewal occurs, Zee said. Long life comes from eating right, studies say.

“Now these people were asleep with their eyelids closed,” she explained. “We recorded their breathing, their heart rate, their EKG, and we also drew blood from them to measure melatonin levels while they were sleeping.” Melatonin is a hormone that regulates the body’s circadian rhythm, or sleep and wake body clock.Ī randomized portion of the group repeated that same light level for a second night in the lab, while another group slept with a dim overhead light with a glow roughly equivalent to “a very, very dark, cloudy day or street lights coming in through a window,” Zee said. “We recorded the brainwaves and could tell what sleep stage the person was in,” Zee said. The blood was drawn without ever touching the slumbering participants. So data could be gathered with minimal interference, they slept with an IV with long tubes that snake across the room and through a hole to the researcher’s side of the lab.
