This document discusses heat exhaustion, including its causes, symptoms, treatment, and how to prevent it. It defines heat exhaustion as when the body is unable to cool itself and if left untreated can lead to heat stroke. The document outlines the key symptoms of heat exhaustion as headache, dizziness, sweating, nausea and cramps. It provides steps for treatment, which include rehydration, cooling the person, and monitoring their condition. Prevention tips emphasize hydration, rest, and avoiding overexertion in hot weather.
The document discusses the effects of cold exposure on the human body. It describes how factors like low temperatures, wind chill, humidity, and altitude can impact regions. Prolonged cold exposure can cause hypothermia, a dangerous drop in core body temperature, as well as localized injuries like frostbite and trench foot. The summary describes treatment for hypothermia, which focuses on gradually rewarming the core body temperature, and treatments for local cold injuries like frostbite, which involves carefully rewarming affected areas and preventing further tissue damage. Prevention emphasizes adequate clothing, shelter, nutrition, foot care, and rapid treatment of any cold injuries.
This document discusses heat emergencies ranging from minor issues like heat cramps and heat rash to life-threatening heat stroke. The body cools itself through sweating and blood flow changes but may become overwhelmed in extreme heat. Heat stroke is a medical emergency defined by a core temperature over 104°F and altered mental status. Treatment involves rapid cooling through methods like evaporative cooling, immersion, or ice packs while providing IV fluids and monitoring for complications like hypotension, hypokalemia, or renal failure. High risk groups include the elderly, young, chronically ill, and those engaged in strenuous activity in hot conditions.
Hyperthermia occurs when body temperature rises above normal levels, with symptoms including shivering, clumsiness, slurred speech, confusion, and fatigue. If not addressed, cells will die and ultimately result in death. To cope, the body cools internal organs and one should drink water. Hypothermia is when body temperature falls below average, with symptoms like shivering, dizziness, hunger, faster breathing, trouble speaking, and slight confusion. To treat, move the person somewhere warm, remove wet clothing, wrap them in blankets protecting head and torso first.
Heat-related illnesses range from mild conditions like heat syncope to life-threatening heatstroke. The body normally cools itself through sweating and other mechanisms, but high humidity or dehydration can interfere with cooling. Heatstroke occurs when thermoregulation fails and the core body temperature exceeds 40.5°C. Symptoms include confusion, seizures, and organ damage. Treatment involves rapid cooling through cold fluids, ice packs, and fans before complications develop. Proper hydration and acclimatization can prevent exertional heat illnesses.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

1. Heat stress :
Workers at risk of heat stress include outdoor workers and workers in hot
environments such as firefighters, bakery workers, farmers, construction
workers, miners, boiler room workers, factory workers, and others. Workers at
greater risk of heat stress include those who are 65 years of age or older, are
overweight, have heart disease or high blood pressure, or take medications that
may be affected by extreme heat resulting in heat stress.
Prevention of heat stress in workers is important. Employers should provide
training to workers so they understand what heat stress is, how it affects their
health and safety, and how it can be prevented.
Heat Stroke:
Heat stroke is the most serious of health problems associated with working in
hot environments. It occurs when the body's temperature regulatory system fails
and sweating becomes inadequate. The body's only effective means of
removing excess heat is compromised with little warning to the victim that a
crisis stage has been reached.
A heat stroke victim's skin is hot, usually dry, red or spotted. Body temperature
is usually 105_F or higher, and the victim is mentally confused, delirious,
perhaps in convulsions, or unconscious. Unless the victim receives quick and
appropriate treatment, death can occur. Any person with signs or symptoms of
heat stroke requires immediate hospitalization. However, first aid should be
immediately administered.
This includes removing the victim to a cool area, thoroughly soaking the clothing
with water, and vigorously fanning the body to increase cooling. Further
treatment at a medical facility should be directed to the continuation of the
cooling process and the monitoring of complications which often accompany the
heat stroke. Early recognition and treatment of heat stroke are the only means
of preventing permanent brain damage or death.
Heat Exhaustion:
Heat exhaustion includes several clinical disorders having symptoms which may
resemble the early symptoms of heat stroke. Heat exhaustion is caused by the
2. loss of large amounts of fluid by sweating, sometimes with excessive loss of
salt.
A worker suffering from heat exhaustion still sweats but experiences extreme
weakness or fatigue, giddiness, nausea, or headache. In more serious cases,
the victim may vomit or lose consciousness. The skin is clammy and moist, the
complexion is pale or flushed, and the body temperature is normal or only
slightly elevated.In most cases, treatment involves having the victim rest in a
cool place and drink plenty of liquids.
Victims with mild cases of heat exhaustion usually recover spontaneously with
this treatment. Those with severe cases may require extended care for several
days. There are no known permanent effects.CAUTION Persons with heart
problems or those on a low sodium diet who work in hot environments should
consult a physician about what to do under these conditions.
Heat Cramps
Heat cramps are painful spasms of the muscles that occur among those who
sweat profusely in heat, drink large quantities of water, but do not adequately
replace the body's salt loss. The drinking of large quantities of water tends to
dilute the body's fluids, while the body continues to lose salt. Shortly thereafter,
the low salt level in the muscles causes painful cramps. The affected muscles
may
Transient Heat Fatigue:
Transient heat fatigue refers to the temporary state of discomfort and mental or
psychological strain arising from prolonged heat exposure. Workers
unaccustomed to the heat are particularly susceptible and can suffer, to varying
degrees, a decline in task performance, coordination, alertness, and vigilance.
The severity of transient heat fatigue will be lessened by a period of gradual
adjustment to the hot environment (heat acclimatization).
3. Fainting:
A worker who is not accustomed to hot environments and who stands erect and
immobile in the heat may faint. With enlarged blood vessels in the skin and in
the lower part of the body due to the body's attempts to control internal
temperature, blood may pool there rather than return to the heart to be pumped
to the brain. Upon lying down, the worker should soon recover. By moving
around, and thereby preventing blood from pooling, the patient can prevent
further fainting. Heat Rash Heat rash, also known as prickly heat, is likely to
occur in hot, humid environments where sweat is not easily removed from the
surface of the skin by evaporation and the skin remains wet most of the time.
The sweat ducts become plugged, and a skin rash soon appears. When the rash
is extensive or when it is complicated by infection, prickly heat can be very
uncomfortable and may reduce a worker's performance. The worker can prevent
this condition by resting in a cool place part of each day and by regularly
bathing and drying the skin.
Hazard Control:
Engineering Controls:
• Ensure all inside areas have adequate ventilation
• Provide shaded awnings for outside work when possible
4. • Provide portable ventilation when possible
Administrative Controls:
• Provide training to all affected employees
• Provide adequate and sanitary drinking facilities and utensils
• Rotate workers during high heat operations
Protective Equipment:
• Provide cooling PPE when appropriate
How the Body Handles Heat:
The human body, being warm blooded, maintains a fairly constant internal
temperature, even though it is being exposed to varying environmental
temperatures. To keep internal body temperatures within safe limits, the body
must get rid of its excess heat, primarily through varying the rate and amount of
blood circulation through the skin and the release of fluid onto the skin by the
sweat glands. These automatic responses usually occur when the temperature
of the blood exceeds 98.6ºF and are kept in balance and controlled by the brain.
In this process of lowering internal body temperature, the heart begins to pump
more blood, blood vessels expand to accommodate the increased flow, and the
microscopic blood vessels (capillaries) which thread through the upper layers of
the skin begin to fill with blood. The blood circulates closer to the surface of the
skin, and the excess heat is lost to the cooler environment. If heat loss from
increased blood circulation through the skin is not adequate, the brain continues
to sense overheating and signals the sweat glands in the skin to shed large
quantities of sweat onto the skin surface. Evaporation of sweat cools the skin,
eliminating large quantities of heat from the body.
5. Safety Problems
Certain safety problems are common to hot environments. Heat tends to
promote accidents due to the slipperiness of sweaty palms, dizziness, or the
fogging of safety glasses. Wherever there exists molten metal, hot surfaces,
steam, etc., the possibility of burns from accidental contact also exists.Aside
from these obvious dangers, the frequency of accidents, in general, appears to
be higher in hot environments than in more moderate environmental conditions.
One reason is that working in a hot environment lowers the mental alertness
and physical performance of an individual. Increased body temperature and
physical discomfort promote irritability, anger, and other emotional states which
sometimes cause workers to overlook safety procedures or to divert attention
from hazardous tasks.
