Drinking more water, exercising regularly and taking Vitamin D are the top steps Brits take to try to boost their immune system, research has found.
Nearly two in five adults (37%) have started taking their immune system “more seriously” over the past two years – and have tried drinking lemon water, gargling salt water, and even having more sex, in a bid to build their natural defences.
But the poll of 2,000 people found that more than one in four (27%) are willing to try more “extreme” steps to boost immunity – with 4% even trying colonic irrigation, the practice of injecting water via the anus to flush out toxins from the colon.
