Rising stress levels have increased the sales of the SleepGuard biofeedback headband, according to Holistic Technologies, which manufactures the device.
SleepGuard reduces TMJ pain by helping people learn to subconsciously keep a relaxed jaw during sleep, according to the company.
"We were surprised to find that SleepGuard sales have increased 50% over the past two months," said Holistic Technologies CEO Lee Weinstein. "We found that the trend is largely based on increased anxiety about the economy as well as the pending presidential election."
