In the winter, you often wake up and draw the curtains only to not be able to see outside due to the condensation. It can be a real problem in people's homes during this time of year.
The cold air from outside clashes with the warm air from inside to create moisture. If left as it is, condensation can turn into mould which is unpleasant and can be damaging to your health.
The Mirror reports many people are noticing a build up of condensation in their bedrooms. One social media user took to Tiktok to share her confusion: "We always get condensation but only one window in the whole house and always in the morning... it baffles me."
