Sometimes, army or Home Team officers who conduct training want to push trainees.
But how do they know what the safe limit is (NSF dies after being warded for heatstroke; May 1)?
Measuring equipment have always been impartial and accurate guides. Why not use them?
There are devices readily available in the market to keep track of things like heart rate, temperature and oxygen level, albeit separately.
Step trackers can also monitor heart rates, but such devices have been known to pose a security risk in army camps due to their Global Positioning System (GPS) tracking signal.
Thus, the better solution would be for us to develop a new device that is able to read a person's vital signs, but without the GPS tracking.
This device should be worn by full-time national servicemen (NSFs) during training exercises, and sound loudly if it detects a heart rate above the safe level, body temperature above the safe level, and oxygen below the safe level.
The device should be individually tagged so as to prevent theft, and allow conducting officers to accurately identify which trainee has been pushed to his limit and should be taken out of training.
The "safe" limit can also be customised based on trainees' prior physical tests.
Eventually, the data could be used for studies to benefit the Ministry of Health as well as to craft efficient training methods or habits, thereby promoting a healthier nation.
