A new study by researchers at the Boston Children’s Hospital has discovered that sleep-deprived mice have a lower tolerance for pain – but all they need is just a little caffeine to return them to a normal pain-level tolerance.
The mice were first kept awake longer by being given toys and activities to keep them busy, at a time when they naturally would go to sleep – similar to what people do when they stay up too late watching television.
Researchers then exposed the mice to higher amounts of cold, heat or spicey flavors, but found that the sleepy mice couldn’t tolerate it as well. They were given pain medication, such as ibuprofen and morphine, but that didn’t help.
However, when the mice were given caffeine and modanfinil (a drug used to keep keep a person awake), their pain tolerance increased.
The study concluded that chronic pain sufferers would get better results with more sleep and a little caffeine, instead of relying on pain killer medication, according to Science Daily.
