Antioxidants are able to neutralize free radicals, which are formed as a result of metabolic processes, due to smoking, stress and exposure to sunlight.
When free radicals are present in large quantities, oxidative stress occurs, which significantly increases the risk of disease and leads to premature aging of the skin.
Exogenous antioxidants: vitamins, carotenoids, enzymes, flavonoids, etc. Antioxidants neutralize free radicals and thus protect the body.
Heart Rate Variability
Heart Rate Variability is a spontaneous change in heart rate and describes the adaptability of the heart to different situations.
In a healthy heart the frequency of beats is not as regular as a clock. Between two beats, which are represented on the electrocardiogram as the so-called R waves, there are time differences of a few milliseconds. The variability of the time interval between two R waves reflects the Heart Rate Variability Index.
The heartbeat, or pulse, describes the wave of pressure that propagates as a result of the contraction of the heart.
The resting beat is the frequency of the heartbeat in a state of physical rest.
For the correct measurement of the resting beat, it is necessary that the measurement does not take place directly after a physical effort and that the person is at rest.
Biological age is linked to the ability of the heart to adapt to different levels of pressure by varying heart beats. In a healthy person, the time interval between two heartbeats is therefore not always identical. With aging, this adaptive capacity decreases. The progression of the aging process is very dependent on the lifestyle of the individual: a healthy lifestyle helps people to age more slowly than their age group, and an unhealthy lifestyle leads to faster aging. The current biological age can then be calculated by measuring the adaptability of the heart.
