Your bedroom may feel cool enough when you go to bed but too cold a few hours later. An air conditioner that changes its settings on its own could save you from waking up to reach for the remote.
Samsung’s WindFree AI Expert Split Type Air Conditioner can connect to a compatible Galaxy Watch through the SmartThings app. According to Samsung, the watch can detect when you fall asleep and “tell” the air conditioner to change how it cools the room.
Called WindFree Wearable Good Sleep, the feature turns on gentler airflow once the watch detects sleep. Samsung says it then adjusts cooling based on your sleep patterns, so you do not have to keep changing the settings yourself.
WindFree cooling sends air through 23,000 tiny holes on the front of the unit. This spreads cool air more gently around the room, helping avoid a strong blast of cold air while you sleep.
A comfortable room temperature can help with sleep. The US Centers for Disease Control and Prevention recommends keeping bedrooms cool. However, people have different preferences: What feels comfortable to one person may feel too cold to another.
In a September 2025 Samsung Health App survey, 66% of respondents said they were working to improve their sleep. The survey included 5,795 people from seven markets, including the Philippines. The result covers all seven markets, not just Philippine respondents.
To use the feature, users need a compatible watch and phone, the SmartThings app, and a home Wi-Fi connection for the air conditioner. They must wear the watch, Galaxy Watch4 and later models as supported devices, while sleeping.
The feature makes cooling easier to control during the night. While gentler airflow may make the bedroom more comfortable, Samsung’s announcement does not provide clinical evidence that the air conditioner prevents people from waking up. It does not guarantee better sleep.
