If sleeping with the air conditioner (AC) on all night leaves your skin feeling rough and dry when you wake up in the morning, Dr Jushya Sarin has a solution. Taking to Instagram, the dermatolog suggested keeping a bucket of clean water in the room. “When the water evaporates, it adds a bit of moure back into the room,” she explained in the video.
Does it really help?
Dr Shivakumar K, MD, Respiratory Medicine and chief consultant pulmonolog at Kauvery Hospital, Marathahalli, Bengaluru, says that air conditioners (AC) tend to reduce humidity in a room drawing out moure as they cool the air. And dry air translates to dry skin, itchy eyes, and irritated mucous membranes.
“Placing a bucket or bowl of water in the room can help introduce some moure back into the air through a natural process called evaporation. Placing water in a pan would make evaporation faster,” he tells .

While it is not as powerful as a humidifier, Dr Shivakumar believes this method can offer modest relief in smaller or moderately cooled spaces, especially when the air feels noticeably dry.
He adds that sleeping with AC overnight can lead to dry eyes and dehydration due to reduced humidity. The cold air produced the AC can remove moure from the skin, causing dryness. There is also an increased risk of respiratory issues due to the low humidity and circulated air,” she points out.

What else can you do?
To minimise these effects, Dr Reddy advises taking regular breaks and exposing yourself to natural air and temperature.
“Spending 2 to 3 hours in an air-conditioned room is sufficient. At night, you can set the AC to turn off automatically after 2 to 3 hours,” he shares, adding that maintaining the temperature in a comfortable range, such as 22 to 26 degrees Celsius, and keeping humidity levels between 40 to 60% is ideal. Using HEPA filters in ACs can also help reduce dust and allergens.

In conclusion, you don’t need to ditch the AC altogether to stay cool and comfortable.
Dr Reddy suggests drinking plenty of water to combat the drying effects of AC, and embracing the humidifier to add moure back into the air with a humidifier helps prevent dry skin and eyes. “Take breaks outdoors or in naturally ventilated areas to allow your body to adjust to different temperatures,” he says. And finally, use mourisers to keep your skin hydrated and healthy.
