The Baevsky Stress Index, also known as the Baevsky Index, is a physiological parameter used to assess a person’s stress level. It is named after its creator, Russian physiologist Professor Oleg Baevsky. The index is derived from heart rate variability (HRV) measurements, which is the variation in time between successive heartbeats.
Heart rate variability is influenced by the autonomic nervous system, which has two branches: the sympathetic nervous system (responsible for the “fight or flight” response) and the parasympathetic nervous system (responsible for the “rest and digest” response). During stress or intense emotions, the sympathetic nervous system becomes more active, leading to changes in heart rate and HRV.
The Baevsky Stress Index quantifies the ratio between low-frequency (LF) and high-frequency (HF) components of heart rate variability. The LF component is associated with sympathetic activity, while the HF component is linked to parasympathetic activity. A higher LF/HF ratio suggests a dominance of sympathetic activity, which is often related to stress, anxiety, and other physiological responses to challenging situations.
In practical terms, the Baevsky Stress Index is calculated from an electrocardiogram (ECG) recording. It is utilized in various fields such as medicine, psychology, and sports to monitor stress levels and overall autonomic nervous system balance. However, it’s important to note that while the Baevsky Stress Index can provide insights into stress levels, it should be considered as part of a comprehensive assessment alongside other clinical and contextual information.
The formula for the Baevsky stress index is:SI = AMo × 100% / 2Mo × MxDMn where AMo is the mode of the distribution of RR intervals, Mo is the number of RR intervals in the mode, Mx is the maximum number of successive RR intervals that differ by more than 50 ms, and DMn is the difference between the minimum and maximum numbers of successive RR intervals that differ by more than 50 ms. The Baevsky stress index is used to evaluate autonomic function and to assess sympathetic tone.
The Fitzpatrick scale is a numerical classification schema for human skin color developed by American dermatologist Thomas B. Fitzpatrick in 1975. The scale is used to estimate the response of different types of skin to ultraviolet (UV) light and to determine a patient’s risk of burning or tanning when exposed to UV light. The Fitzpatrick scale remains a recognized tool for dermatological research into human skin pigmentation.The scale classifies skin into six categories based on skin color and how it responds to the sun. The following are the six categories of the Fitzpatrick scale in relation to the 36 categories of the older von Luschan scale (in parenthesis)
- Type I (scores 0–6) always burns, never tans (palest; freckles)
- Type II (scores 7–13) usually burns, tans minimally
- Type III (scores 14–20) sometimes mild burn, tans uniformly
- Type IV (scores 21–27) burns minimally, always tans well (moderate brown)
- Type V (scores 28–34) very rarely burns, tans very easily (dark brown)
- Type VI (scores 35–36) never burns (deeply pigmented dark brown to darkest brown)
The Fitzpatrick scale has some limitations, including that the original version of the scale did not contain classifications for darker skin tones. In its first version, the scale only included types I to IV and was considered “Anglo-Irish centric.” Types V and VI were added later.
