Sleep tracking:
Your light, deep, and REM cycles during the night will be given by sleep tracking. The watch would let you know exactly how much sleep did you get, and you can see different patterns in sleeping behavior over the week or month.
Blood pressure monitoring:
A very important feature for those who have this medical condition and constantly needs to check their blood pressure all the time. Although the readings are taken from wearables cannot be used for medical purposes per se, but they can be used for indication.
Pulse Oximeter (SpO2 sensor) and Breathing Guide:
SpO2 sensor would let you know the amount of oxygen your blood is carrying, and if goes under a specific limit then the body might not function properly. It’s not something you would need to know all the time, but can come in handy in several situations. SpO2 sensor would also help you with your breathing issues
Stress tracking:
If the watch has stress tracking, then you’d get notified whenever it senses that you’re feeling stressed out. After that, the breathing guide would help you relax for a bit, which would be good for a lot of people facing stress and anxiety.
Body/Skin temperature tracking:
Not every smartwatch comes with this feature, and although it doesn’t eliminate the need of using a thermometer for checking your body temperature, it rather gives you an edge of tracks whenever you want to.
Of course, you won’t be carrying a thermometer with you all the time, so it’s better to have this feature on your wrist, so you can measure your body temperature if you feel any changes.
Sedentary reminder:
If you’re doing work from home, and your job is to sit in front of your computer/laptop for hours, then your watch should have a sedentary reminder. This would notify you to take a break and walk for a while, so it doesn’t affect your health and back strength as well.
