Fouillet A, Rey G, Laurent F, Pavillon G, Bellec S, Guihenneuc-Jouyaux C, et al. Mortality during heat waves in New York City in July 1972 and August 1973. Fouillet A, Rey G, Laurent F, Pavillon G, Bellec S, Guihenneuc-Jouyaux C, et al.
Oral atorvastatin therapy restores cutaneous microvascular function by decreasing arginase activity in hypercholesterolaemic humans. There are several theories as to why older females store more heat than younger females during intense exercise. Low-dose aspirin and clopidogrel independently attenuate reflex cutaneous vasodilation in middle-aged humans.
Oral sapropterin enhances reflex vasodilation in aged human skin via nitric oxide-dependent mechanisms, according to the United Nations Department of Economic and Social Affairs’ Population Division. World population ageing, 1950u20132050. New York: United Nations; p. 483.

The abnormally hot daily temperatures in early August 2003 were followed by a dramatic increase in mortality, mostly among the elderly. Redrawn from Dousset et al. International Journal of Climatology 2011, 31:313u2013323.
How does heatwave affect elderly?
Heart, lung, and kidney diseases, as well as any illness that causes general weakness or fever; high blood pressure or other conditions that necessitate dietary changes, such as salt-restricted diets; high blood pressure or other conditions that necessitate dietary changes, such as salt-restricted diets.
Why do older patients die in a heatwave?
Increased cardiovascular demand during heat waves is often fatal in the elderly due to increased strain on an already compromised left ventricle, so excess deaths during heat waves are disproportionately older people and overwhelmingly cardiovascular in nature.
How many people die annually from heatstroke?
According to some statistical methods, extreme heat causes more than 1,300 deaths per year in the United States, compared to about 600 deaths per year in the u201cunderlying and contributing causesu201d data set depicted in Figure 1.
Can elderly die from heat?
The Centers for Disease Control and Prevention estimates that over 650 people die each year from heat-related illnesses, with older adults being more susceptible to heat stroke, heat cramps, heat exhaustion, and other serious health problems as a result of poorer circulation and less effective sweating.
What room temperature is too hot for seniors?
Their health is jeopardized if the room temperature is below 68 degrees Fahrenheit or above 74 degrees Fahrenheit, as these temperatures are outside the safe range.
What outdoor temperature is too hot for elderly?

How fast can you die of heat stroke?
Within a few steps, your body begins to respond to the sun’s radiation, the moist air pressing against your skin, and the heat generated by your own rising metabolism, giving you just under two hours.

What is a normal temperature for an elderly person?
Adults. The average body temperature in adults ranges from 97u00b0F (36.1u00b0C) to 99u00b0F (37.2u00b0C). Adults over 65. The average body temperature in older adults is lower than 98.6u00b0F (37u00b0C).
Why would an elderly person be cold?
Our circulation decreases as we age due to the natural loss of elasticity in the walls of our blood vessels; as blood moves slower through our bodies, our extremities become colder and colder more quickly; another possible cause of feeling colder as we age is the thinning fat layer beneath our skin that conserves heat.
What temperature is too low for elderly?
A body temperature of 95u00b0F or lower in an older person can cause a variety of health problems, including a heart attack, kidney problems, liver damage, and even death. Being outside in the cold, or even being in a very cold house, can cause hypothermia.
