Cold adaption and high blood pressure
It is important to note that high blood pressure (hypertension) symptoms may go unnoticed and may typically take a few years to develop and cause damage. The damage may cause devastating effects – increasing the risk of heart disease, stroke, hardening of arteries and diabetes.
Having seen a cardiologist (heart doctor) this week I was informed that I’ve had high blood pressure for two years (unknown to me, and previously having been told that my blood pressure was normal). This happened to coincide with the time I started cold adapting – cold baths for 45 mins, and cryogenic chamber work.
It should be noted that high blood pressure varies from person to person and with age.
120/80 mm/Hg is considered healthy
120 to 139/80 to 89 is called pre-hypertension
140 to 159/90 to 99 is called stage 1 hypertension
160/100 is called stage 2 hypertension.
Through the day my blood pressure ranged from 205/130 to 151/93, with a mean of 181/112. An interesting test made during measurements showed that pipe breathing lowered the lower value (heart pumping empty part of the cycle). :) Also, it should be noted that my age is approaching 69 years.
Common symptoms of high blood pressure are often none! Yet may include one or more of the following: headaches, irritability, dizziness, fatigue, sleeplessness, frequent urination and depression.
I have experience depression in the past two years (and had a rational reason for its cause), and fatigue, yet none of the other symptoms (frequent urination has been less since coming off a prostate protocol :)).
My high blood pressure first came to light with a loss of ‘balance’ (to the left) whilst walking (yet with a lack of dizziness) and onset of fatigue - thought to have been caused by a micro stroke, although a brain scan has ruled this out – and a visit to a cardiologist (who has confirmed that my heart is OK). I still have a second visit to an ear specialist to check out any possible ear balance issues.
Getting back to cold adaption, it appears that this may raise blood pressure levels, if doing the full 15C for 15 mins (or equivalent). The message is to take care and avoid overdoing the cold adaption process, especially if you are ‘elderly’. And, to keep an eye on your blood pressure levels.
Cold adaption and hypothermia
Hypothermia is caused by a drop in body temperature caused by prolonged exposure to cold temperatures.
Onset depends on a person’s age, weight, body fat, overall health and the amount of time exposed to the cold. Shivering is a positive response to produce heat through muscle activity.
People at risk include the elderly.
Symptoms of mild hypothermia include: dizziness, faster breathing, increased heart rate (mine has jumped from low 60’s to high 80’s), hunger (NB, this is over and above any hunger symptoms for those on a keto diet who are eating insufficient fat with their protein intake (a classic symptom – as in eating too much protein and a low fat intake)).
Signs of moderate hypothermia include: slow, shallow breathing, confusion and memory loss (over and above normal), loss of co-ordination – stumbling steps and fumbling hands, turning ‘blue (lips and extremities)’. People have commented on my ‘blue’ lips on getting out of a 15C spring pool after a 15 min immersion (I was unaware of this myself).
So, overall, the message with cold adaption is to take care and to avoid overdoing the process, especially for those who are ‘elderly’.
