The problem with breathing disturbances like sleep apnoea is that it's almost impossible to tell you have them – because you sleep through the telltale symptoms.
But that's where one new high-tech watch promises to help by letting you keep track of your heart rate and rhythm both day and night.
The ScanWatch from Withings, monitors blood oxygen saturation levels (SpO2) to detect whether wearers suffer from sleep apnoea syndrome – a temporary breathing disorder that leads to oxygen deficiency.
The makers say the watch, which also looks for conditions such as atrial fibrillation and heart rhythm disorders, then gives you a notification when you wake up in the morning.
Sleep apnoea, characterised by stopping breathing and starting making gasping, snorting or choking noises when asleep, is often accompanied by daytime symptoms such as feeling very tired, finding it hard to concentrate and mood swings.
Unveiled at this year's technology trade fair CES in Las Vegas, the watch measures pulse, ECG and other activity, and shares the data via Bluetooth Low Energy with the Withings app and other training apps.
The ScanWatch will go on sale later this year for around US$280 (RM1,140). The manufacturer says the battery will last for about a month without recharging. – dpa
