Aromachology is the study of the influence of odors on human behavior and to examine the relationship between feelings and emotions. Those who practice aromachology are aromachologists . Aromachologists analyze emotions such as relaxation, exhilaration, sensuality, happiness and well-being brought about by odors stimulating the olfactory ...
Humans can olfactorily detect blood-related kin. [17] Mothers can identify by body odor their biological children, but not their stepchildren. Preadolescent children can olfactorily detect their full siblings, but not half-siblings or step-siblings, and this might explain incest avoidance and the Westermarck effect . [ 25 ]
Odor threshold value can be expressed as a concentration in water or concentration in air. Two major types of flavor thresholds can be distinguished: the absolute and the difference threshold. The odor detection threshold and the odor recognition threshold are absolute thresholds; the first is the minimum concentration at which an odor can be ...
Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Osler's sign (or Osler sign) of pseudohypertension is a falsely elevated blood pressure reading obtained through sphygmomanometry due to calcification of blood vessels which cannot be compressed.

A new study has shown that exposure to a fishy smell can make people more suspicious, raising their level of critical thinking skills. Fishy smell shown to boost critical thinking in humans Skip ...
The smaller arteries and arterioles have higher resistance, and confer the main blood pressure drop across major arteries to capillaries in the circulatory system. Illustration demonstrating how vessel narrowing, or vasoconstriction, increases blood pressure. In the arterioles blood pressure is lower than in the major arteries.
Mean blood pressure rises from early adulthood, plateauing in mid-life, while pulse pressure rises quite markedly after the age of 40. Consequently, in many older people, systolic blood pressure often exceeds the normal adult range, [33] if the diastolic pressure is in the normal range this is termed isolated systolic hypertension.
The human nose is sensitive to geosmin and can detect it at concentrations as low as 0.4 parts per billion. [15] Some scientists believe that humans appreciate the rain scent because ancestors may have relied on rainy weather for survival. [16] Camels in the desert also rely on petrichor to locate sources of water such as oases. [17]
