Do any of you monitor your heart rate variability? How does taking rapamycin effect HRV in the short term?
I recently started using a polar chestband. I was a bit disappointed with how low my HRV was, but then wondered if having taken rapa on Sunday had anything to do with it.
I monitor HRV daily with my Oura ring and havenāt noticed any effect of rapa. Yes, definitely should exercise more (Zone 2 training) and try to get stress levels down and optimize sleep to improve HRV.
I track my HRV too my Oura ring also and I noticed that when I donāt eat anything in the evening hours past 7 PM I have high HRV readings. If I snack on something after 7 PM throughout the evening I Get Low HRV readings.
I monitor HRV and havenāt seen any change with rapamycin. I did have relatively low HRV a while back, so I did the breath course on Elite HRV (which is free). It went up dramatically and stayed there.
Breathing exercises can also increase HRV. I use a polar chestband and Elite HRV to measure it. I also look at the HRV value on Fitbit. I have no real confidence in the fitbit value. (I use a Sense) The Elite value tends to be something like twice fitbit.
This morning Elite/Polar said 60ms and Fitbit said 27ms. I am 62 and am quite happy with an HRV of 60ms plus (it trends down with age). I am not particularly fit. I donāt run, but I do some resistance training upper body exercises and I walk briskly. I do not visit a gym.
I am using box breathing with a 5 heartbeat cycle to improve the Vagus nerve and potentially improve HRV. I donāt have solid figure on this, but I think I have pushed it (Elite HRV) up by about 5ms by using box breathing.
Maybe but I measure at around the same time each day of the week and have a set workout schedule, so days of the week should be comparable. At least rapamycin does not decrease my HRV
My view is that what matters is consistency. If you are taking a measurement during sleep then it can only be compared to other measurements during sleep.
I think myself that the value awake is probably better because of the greater activity of the HPA axis, but I record both although it appears that awake values are more commonly used for research.
