Appendix B: Cold-Weather Ritual Guidelines
Note: These guidelines are generalised. Leaders of covens
with extensive extreme cold- weather experience and specialised
equipment may opt to use less conservative guidelines. People
with prior history of cold-weather injury should take greater
precautions.
Table B-1: Guidelines for Sedentary Activities
Examples: Fire guard, pathworking, meditations, eating,
resting, sleeping, journal- keeping
- Little Danger: equivalent chill temperature above -30 C
(-22 F)
- Full head cover. Do not wear facial make-up or ritual masks
below -12 C (10 F). Wear mukluks below -18 C (0 F). Shorten time
outside / time inside cycles. Provide warming facilities.
- Increased Danger: equivalent chill temperature between
-30 C (-22 F) and -57 C (-70 F)
- Consider postponing ritual until weather improves. Use 15
to 20 minute work cycles for essential tasks only. Work in groups
of no less than 2 people. No exposed skin.
- Great Danger: equivalent chill temperature below -57 C
(-70 F)
- Cancel outdoor activities
Table B-2: Guidelines for Low-Intensity Activities
Examples: Walking, slow dancing, casting Circle, cooking
or serving meals.
- Little Danger: equivalent chill temperature above -30 C
(-22 F)
- Increase surveillance. Cover exposed flesh when possible.
Mittens with liners. Do not use facial make-up or ritual masks
below -12 C (10 F). Full head cover below -18 C (0 F). Keep skin
dry - especially around nose and mouth.
- Increased Danger: equivalent chill temperature between
-30 C (-22 F) and -57 C (-70 F)
- Restrict non-essential activities. Use 30 to 40-minute work
cycles with frequent health and safety surveillance for essential
tasks.
- Great Danger: equivalent chill temperature below -57 C
(-70 F)
- Cancel outdoor activities
Table B-3: Guidelines for High-Intensity Activities
Examples: Digging hole for Maypole in frozen ground, building
structures out of snow blocks or shovelled snow, clearing pathways
or ritual grounds, running, dancing, making or breaking camp.
- Little Danger: equivalent chill temperature above -30 C
(-22 F)
- Increase health and safety surveillance by coven leaders.
Gloves optional - mandatory below -18 C (0 F). Increased hydration.
- Increased Danger: equivalent chill temperature between
-30 C (-22 F) and -57 C (-70 F)
- Layer ski-wear or equivalent. Mittens with liners. No facial
make-up or ritual masks. Exposed skin covered and kept dry. Rest
in warm, sheltered area. Mukluks below -18 C (0 F)
- Great Danger: equivalent chill temperature below -57 C
(-70 F)
- Postpone non-essential outdoor rites or excursions. Essential
tasks only with less than 15 minute exposure. Work groups of no
less than 2. Cover all exposed skin.
Appendix C:. Individual Cold-Weather Survival Kit
- Waterproof matches and fire starter (e.g. candle, magnesium
match)
- Signalling devices (e.g. mirror and whistle)
- Knife (jack-knife or Swiss Army knife is ideal)
- Pressure bandage
- Cold-climate lip balm ("Chapstick")
- Sunglasses
- Compass
- Water container (metal for use over fire)
- Small amount of concentrated food (e.g. trail mix)
- Foil survival blanket (one commercial brand is the Space Blanket)
- Flameless, waterless chemical heater (e.g. "Pocket Rocket"
or "Husky Hand-Warmer")
Appendix D: Common Nutrition-Related Medical Complaints
Diarrhoea
Diarrhoea is the excessive excretion of watery stools (instead
of formed or soft stool) with resulting decrease in absorption
of water and nutrients.
Causes of diarrhoea include:
- Poor personal hygiene (transmission of bacteria by unwashed
hands, utensils, etc.)
- Food poisoning
- Dysentery
- Emotional stress
- Allergies
- Excessive drinking of alcohol
- Intestinal virus
Symptoms:
- Frequent loose and watery stools
- Stomach cramping
- Blood streaks in or on stools
- Tiredness (due to loss of potassium)
- Thirst (due to fluid loss)
Treatment:
Treatment is mainly concerned with prevention or correction of
salt and water depletion. The Canadian Medical Association suggests
the following:
- Consume a liquid diet for a day or so. Suggestions: tea, clear
broth or soup, glucose- electrolyte type sport drink, beverage
base.
- Avoid solid foods, but consume large volumes of fluid.
- If diarrhoea persists longer than a day or two, or if urine
decreases in frequency and amount, seek medical attention because
severe dehydration may occur.
- If bloody or black stools occur, or if severe or prolonged
stomach cramping occurs, seek prompt medical attention.
Dehydration
Dehydration is the net result of inadequate fluid replacement
in the face of normal or accelerated fluid loss. It can happen
at any temperature, whether physical activity is involved or not.
Causes of dehydration in winter are usually sustained physical
exertion while wearing heavy winter clothing, combined with not
replacing lost fluids. Dehydration could also be caused by illnesses
involving diarrhoea or vomiting.
Symptoms of dehydration depend on the percent body weight lost
due to dehydration. Fluid loss resulting in as low as 2% loss
of body weight can compromise physical performance. A 3-5% loss
in body weight leads to a diminished work capacity while a 10-15%
loss results in severe disability and even death.
The following chart summarises the symptoms of dehydration at
different percentages of body water loss (listed as percent of
body weight loss).
Table 14: Symptoms of dehydration as percent of body weight
loss
- 1 - 5%
- Thirst; vague discomfort; economy of movement; appetite suppression;
flushed skin; impatience; sleepiness; increased pulse rate.
- 6 - 10%
- Dizziness; headache; difficulty breathing; tingling in limbs;
absence of salivation; bluish tinge to skin; indistinct speech;
inability to walk.
- 11 - 20%
- Delirium; muscle spasms; swollen tongue; inability to swallow;
deafness; dim vision; numb, shrivelled skin; painful urination;
kidney dysfunction.
Treatment and Prevention:
Treatment varies depending on the degree of dehydration. For the
least severe cases, simply drinking enough fluids (preferably
water) to replace lost fluids, getting plenty of rest, and getting
out of the sun should help solve the problem.
For the more severe cases of dehydration (symptoms in the 6-10%
range and higher), it should be treated as an emergency by seeking
prompt professional medical attention, including intravenous fluid
replacement.
The easiest way to prevent dehydration is to drink adequate water
prior to working outdoors in heavy clothing. For example, drinking
13 to 20 ounces of water (preferably warm) beforehand will delay
dehydration.
While working, up to 2 litres (2 quarts) of fluid may be needed
per hour to help prevent dehydration. This can be accomplished
best by drinking about 250 ml (1 cup) of fluid every 10 to 15
minutes. There are instances where this is not enough fluid to
replace sweat losses, but it is the most that can be emptied from
the stomach in an hour (more plain water can be absorbed per hour
than flavoured drinks).
Therefore, even when the maximum amount of fluid is drunk, in
some conditions it is necessary to still watch for signs of dehydration
because it will be impossible to maintain adequate hydration.
Work-rest cycles help fluid absorption keep pace with fluid loss.
Constipation
Constipation is a symptom, not a disease. It is characterized
by retention of feces in the colon beyond the normal emptying
time.
Causes of constipation include:
- Dehydration
- Fibre-deficient diets
- Rectal diseases
- Diseases of the colon
- Lack of exercise (decreases intestinal muscle tone)
- Abrupt living habit changes
- Drugs (e.g., analgesics, antacids)
- Prolonged use of laxatives
Symptoms:
Constipation manifests as excessive straining, pain, and incomplete
bowel movements.
Treatment and Prevention:
Reduce the risk of constipation by increasing fluid intake, increasing
the intake of dietary fibre, and exercise. If constipation persists,
contact a nurse or physician.
