Scientists have revealed that people who swim in cold water are at a lower risk of dementia and other degenerative disorders. They have said that taking a dip in cold water can protect the brain from dementia. Experts have observed swimmers in London’s Parliament Hill Lido. There have been increased levels of a cold-shock protein called RBM3 in the bloodstream of all the swimmers. As per the experts, this compound can be created by hibernating mammals, prompting the destruction and re-growth of synapses, which are permanently missing in the case of dementia. It results in cognitive decline and leads to other symptoms of the disease like concentration issues and confusion.
A study on mice with dementia has found that RBM3 protein can delay the onset of degenerative brain issues. A team of scientists from Cambridge University that has been studying the link between dementia and cold-shock protein has reported that a drug can prompt the formation of this protein, which can delay the onset of dementia by years. The study has focused on whether humans can produce this protein by being hypothermic. Hypothermia is a state where the body drops its temperature to 34 degrees Celsius. Experts have tested the swimmers to determine whether they are hypothermic and can produce cold-shock protein. Swimmers have been tested for the protein during the winters of 2016, 2017, and 2018. There has been a control group to compare the findings. Scientists have found that hypothermic swimmers have increased levels of RBM3. At the same time, people who have never entered a pool for swimming have lower levels of the compound.
The lead author of the study, Dr. Giovanna Mallucci has said that humans can produce this protein just like hibernating animals. However, the author has said that cold-water immersion is certainly not a cure for dementia as the risk of dipping temperature can outweigh the benefits of the treatment. Hypothermia can lead to vital organ failure, irregular heartbeat, and at times, it can cause death as well. As per the reports, more than a million people in the UK have been dealing with dementia. While nearly 5.7 million people in the US have been diagnosed with the disorder. Dementia is a condition where the patients lose memory and find it difficult to be involved with a conversation and stay confused about their existence.
