People are being advised to mind their mental health, as well as their physical health, this winter.
Irish Medical Organisation (IMO) Chair Dr Denis McCauley gave Newstalk Breakfast his advice for staying healthy as the weather gets colder.
"It is winter, it is colder [people] are more inclined to get respiratory infections," he said.
"I always dislike the very dark months of October and November from a psychological point of view.
"This is a time that they're more likely to feel unwell physically and psychologically - so rest and keep physically well.
"I think the simple things such as take a multivitamin - particularly vitamin D - and I think vaccination - the flu vaccine and the actual COVID vaccine also if it's relevant for you."
'It'll be OK'
Dr McCauley said "mother advice" is also sound advice.
"Don't get your feet wet, don't stand in a draught - all those things count, believe it or not," he said.
"The other thing is that I think people are very worried about the fuel costs, and they may be inclined to keep their house very cold.
"I think the advice of turning down the thermostat a bit is actually sensible, but you shouldn't be walking around a cold house.
"Psychologically, listen, it'll be OK,” he said.
"We got through the actual COVID crisis, I think we can get through the actual fuel crisis."
His advice in a nutshell: "Keep well physically, keep well psychologically, take a supplement - I do believe in vitamin D."
'All about preparation'
Met Éireann Head of Forecasting Evelyn Cusack said people should be prepared around the home.
"The winter months are actually December, January and February," she said.
"At this stage, it is hard to imagine snow and ice, but really this campaign is all about preparation.
"Very simple things: do you know how to turn off your water, how to turn off your electricity - do you know where that is?
"If you've a dripping tap outside, for example, now's the time to get it fixed when the weather is lovely and mild," she added.
