Smart Home: Improve your sleep

Sleep detection devices can improve our sleep by recording physiological changes in our bodies and customizing and adjusting the room’s temperature, lighting, and other environments.


Neuroscientist Matthew Walker said that sleep devices and intelligent home systems could be combined in the future. There has been increasing interest in sleep in personal health tracking in recent years. All kinds of new devices have started to appear in the reports of prominent we-medisignificanttness guru Joe Rogan wearing a Whoop Strap on his wrist. The device’s algorithm suggested he get four or five hours of sleep a night, rather than the seven or eight he once thought; Aubrey Marcus wears an Oura bracelet that measures various biometrics overnight and evaluates a score the following day.


Wearables like watches, rings and headbands are appealing to those of us who like to check our various biometric data, but they can also cause anxiety and insomnia. Darren Mansfield, a sleep disorders and respiratory physician and associate professor and vice president of the Sleep Health Foundation, believes we need to strike a balance.


Mike Toner runs Thick As Thieves, a dance music agency. He has spent the past decade staying up late at clubs in Melbourne and answering international emails at 3am on his mobile phone. He had been trying to solve his sleep problem for five years.
“I’ve tried everything,” he said. “Magnesium capsules, sprays, melatonin, Chinese herbs… I was even treated at a sleep centre, where I was made to sleep in a room with wires all over my body, my nose stuffed with devices and even a camera pointed at me. Ironically, I slept better that night than I had ever slept before.”


So he decided to start monitoring his own body seriously, keeping an eye out for new devices on Huberman’s lab podcast and The Quantified Scientist. Sleep monitoring wearables have come a long way from being equipped with accelerometers to track movement and algorithms to determine when a person is asleep, to being able to track sleep latency, sleep efficacy, heart rate variability, depth of sleep, RAPID eye movement sleep and sleep position, to name a few.


In addition to these wearables, he also bought various cooling devices. As soon as the weather warms up, Toner lays down his water cooler mattress, Chilipad.


The theory behind the mattress is that lying in a cool room after a hot bath tricks the body into sleep since our body temperature drops when we fall asleep. In general, people tolerate cold temperatures more than heat while asleep.
Staying cool helps you sleep, Mansfield says. “Generally, cooler temperatures are more tolerable at night… 25 degrees Celsius is beautiful and comfortable during the day, but at night, when our core temperature is dropping, it becomes unendurably hot, so 18 or 19 degrees is ideal.”


In the future, we can look forward to the combination of fitness tracking devices with smart indoor furniture, such as smart air conditioning and smart lighting systems. “Over time, using commonly used machine learning algorithms, we should be able to use AI to tell the owner of each bedroom what the most comfortable sleep temperature is based on biophysiological data calculated by sleep tracking devices,” Walker said. “We could even set a natural circadian rhythm, Make the room temperature change every night in harmony with the owner’s body temperature.”
