2.0: Food and Water During Cold-Weather Rituals

Although warm clothing and proper shelter are the first consideration in protecting against the effects of cold weather, adequate food and water consumption are next in importance. People need more food and water when it is cold, and the effects of dehydration and inadequate diet are as serious as in hot climates.

Understanding the Problems

  1. People often become dehydrated during cold weather.
  2. The body's requirement for water is high during cold weather.
  3. Witches, like all people, tend to reduce their fluid intake during all outdoor rites, but especially during cold weather.
  4. Water consumption requirements are more difficult to predict for cold-weather situations than hot, because the effects of the environment are greatly modified by an individual's own bodily responses, the workload and the amount of clothing worn. This individual variability affects the amount of water required to maintain proper hydration.
  5. Caloric requirements of Witches are 25 to 50% higher during cold-weather rites than in warm or hot weather.
  6. Ensuring that Witches in the cold and snow receive adequate amounts of hot food is a major challenge for coven leaders during cold-weather rites, especially when people are camped in tents far from kitchens where food can be heated and kept warm.
  7. Other field-feeding problems often arise from freezing of food supplies (if not stored in a warm area) and a lack of readily available liquid water to rehydrate dry ingredients.

Table 6: Water Requirements Guidelines:


Light
Meditation, reading, sewing, cooking or serving meals: 6 litres / 6 quarts per person/day.
Moderate
Running on trail, dancing, stacking firewood, fetching water, building snow structures: 9 litres / 9 quarts per person/day.
Heavy
Walking in heavy snow, packing supplies along trail, chopping or splitting wood: 12 litres / 12 quarts per person/day.

Note: adjust these amounts according to individual needs. Dark urine indicates that you are not drinking enough water.


Coping with Food and Water Problems

  1. People must drink even when they are not thirsty. Coven leaders should remind people of the need to drink at regular intervals.
  2. Hydration status can be monitored by noting the colour and volume of your own urine.
  3. In extremely cold weather, below -23 C (-10 F), individual water-bottles and collective water jugs can freeze.
  4. Unmelted snow and ice should not be consumed for water.
  5. There may be no better investment for the health, strength and morale of Witches participating in cold-weather campouts and outdoor rites than to provide ample amounts of hot palatable food supplemented with warm beverages. Proper meal planning is critical to successfully ensure that food is still hot when received by each person.
  6. Whenever possible, latrines should be sheltered to protect users from the wind and rain. Witches are less likely to restrict food and fluid intake, if they can use the latrines without being overly exposed to the elements. Here is where the old-fashioned outhouse, with a door that shuts out drafts, really earns its keep.

2.1: Food and Water for High-Altitude Campsites

This chapter discusses the problems inherent in providing adequate food and water supplies to Witches who are camped in high-altitude winter campsites. Things to consider include altitude-induced changes in nutritional requirements, and the effect that diet may have on tolerance to altitude.

Weight Loss Problems

  1. Eating enough food is the most important nutritional factor in the mountains. Almost everyone who goes to high altitude loses weight. People lose both body fat and lean tissue, and at very high altitudes the weight loss is incapacitating. The loss of insulating fat decreases tolerance to cold temperatures. Accompanying the weight loss are fatigue, loss of strength, and psychological changes such as decreased mental alertness and morale. All of these can contribute to accidents and increased rates of illness.
  2. Energy requirements for work at high altitude are 15 to 50% above sea-level requirements. The altitude, cold temperatures, and performance of physical activities over rugged terrain combine to increase energy expenditures to as much as 6000 calories per day.
  3. Although energy expenditures increase, food intake usually decreases due to lack of appetite, limited availability of food, and difficulty in food preparation. During the first 3 to 4 days at high altitude, the headache, nausea, vomiting and pronounced anorexia of acute mountain sickness (AMS) interfere with food and fluid intake. Even after the symptoms of AMS subside, appetite remains depressed and it takes less food to reach a feeling of fullness - the higher the altitude, the greater the appetite depression.
  4. Altitude reduces sense of taste and alters food preferences. These taste changes decrease tolerance to monotonous foods. People will often go hungry at high altitude rather than eat food which they do not crave. Many mountaineers report an aversion to fat and a preference for carbohydrates.
  5. Women may have a biological advantage at altitude. Women, in general, suffer less severe symptoms of AMS and do not experience as great a depression in appetite and food intake as do their male counterparts.
  6. Cooking times double for each 1500-metre (5000-foot) gain in elevation above sea level (since altitude lowers the boiling point of water). Cold ambient temperatures and thin air mean that food starts out colder and heat dissipates faster at altitude. Providing adequate amounts of hot food is a major challenge for coven leaders during high altitude excursions.

Inadequate Carbohydrate Intake

  1. Carbohydrate is best energy source at altitude. Carbohydrates replace depleted muscle glycogen stores, prevent protein from being used as energy, and require less oxygen for metabolism. A high-carbohydrate diet can reduce the onset and severity of AMS and improve physical performance and mental efficiency. A low-carbohydrate diet can result in low blood sugar. Low blood sugar causes confusion, disorientation, and lack of co-ordination; these conditions can be extremely dangerous when combined with oxygen deficiency.
  2. The optimal diet at altitude contains at least 400 grams of carbohydrate, accounting for 60 to 70% of dietary energy supply. Such a high carbohydrate intake is very difficult to achieve unless a concerted effort is made to consume high-carbohydrate foods. Women are at particular risk of inadequate carbohydrate intakes because of their relatively low calorie consumption.
  3. The supposed taste preference for high-carbohydrate foods cannot be counted on to ensure an adequate carbohydrate intake. Not everyone exhibits this food preference, especially at lower altitudes. Many of the common snacks or 'junk food' items that Witches bring to the mountains are high in fat and, therefore, displace preferred carbohydrate from the diet. Typical high-fat foods that Witches pack are cheeses, summer sausage, and jerky.

Dehydration

  1. It is easy to become dehydrated in high-altitude environments. Dehydration increases the risk of cold injury and exacerbates the fatigue, impaired judgement and apathy of hypoxia. The body's requirement for fluids is very high at altitude; often exceeding 12 litres of water per day. This is mainly caused by increased water losses from the lungs due to the increased ventilation of cold, dry air. There is also increased urinary loss of water due to the diuretic effects of altitude and cold. Sweating due to physical exertion adds to the water loss. Especially in the first few days at altitude, there may be significant body water losses due to the vomiting associated with AMS.

    Diarrhoeal fluid losses may also be a factor. Giardia, an intestinal parasite that causes diarrhoea, is very common in the mountains. Also, the high magnesium content of glacier water and glacial-lake water, consumed as drinking water, can have a laxative effect.
  2. Complicating the excessive water losses at altitude is the difficulty of consuming adequate fluids. The sensation of thirst does not keep pace with water loss. People might not feel like drinking, even when they are already dehydrated. AMS further exacerbates the dulling of the thirst sensation.
  3. Safe drinking water is difficult to obtain in the mountains, because surface water sources are often frozen. In any case, because of the body's increased water requirement at altitude, a day's supply cannot be carried by a hiker. When temperatures are very low, water freezes in canteens, water bottles and water jugs, restricting water availability. It takes an exorbitant amount of time and fuel to melt snow in sufficient quantities (it takes 40 minutes to melt 4 cups of snow to make 1 cup of water).
  4. All melted snow and ice, as well as water from streams and lakes, should be considered contaminated. Well water, if it is muddy, should also be considered contaminated. Because at altitude water boils before it reaches 100 C (212 F), the boiling temperature of water at sea level, it needs to be boiled longer than the 10 minutes necessary for sterilisation at sea level. This adds an additional minute for every 300-metre (1000- foot) gain in altitude. For example, at 1800 metres (6000 feet), water needs to be boiled for 16 minutes to be purified.

Gastrointestinal Complaints

  1. Constipation is a common complaint during any extended outdoor ritual. It is especially prevalent at altitude where decreased oxygen slows down the function of the intestines and excessive fluid losses rob water from the colon. Emphasis on adequate fluid intake is the best preventative.
  2. Many people complain of intestinal gas at high altitudes. Responses to particular foods are highly individual and, therefore, difficult to predict. Dehydrated foods high in carbohydrate tend to cause gas production and should be tried in small quantities until tolerance is established.

See Appendix D for further information on possible causes, common symptoms and suggested treatments for gastrointestinal complaints.

2.2: Guidelines for Mountain Cookery

There are several key issues which can be managed. First, the mountain cook must keep the people from losing weight. Second, high-carbohydrate menus should be planned and provided. Third, plenty of drinking water must be provided.

Prevent Weight Loss

  1. Provide adequate calories.
  2. Serve at least two hot meals daily if at all possible. Witches will enthusiastically eat and drink more when they are served hot meals in a group setting.
  3. Use a variety of foods and food items. Monotony is the biggest problem in mountain cookery. Any food becomes tiring with repeated consumption. Almost anything different helps to maintain food intake. Watch out for 'big pot' items - make sure that you have several main course items available, preferably from different ethnic cuisines.
  4. Encourage small meals plus frequent snacks. Large meals are poorly tolerated at altitude. People often cannot consume enough food to meet their nutrient requirements in two or three meals a day. The cook should keep a snack basket handy - it should contain good food that can be carried in a Witch's pocket for later consumption at will.
  5. Respect individual food preferences and tolerances. Do not force food on people who are nauseous or vomiting. Even favourite foods are repulsive at altitude if they are associated with the nausea and vomiting of AMS.

Maintain a High-Carbohydrate Intake

  1. Emphasise high-carbohydrate foods (starches and sugars). Aim for an intake of at least 400 grams of carbohydrate per day. High-carbohydrate items include hot and cold breakfast cereals, juices and sugar-sweetened beverage base, fruits (dried, canned, or fresh), instant mashed potatoes, rice, couscous, noodles, crackers, Fig Newtons, and bran muffins. High-carbohydrate beverages may be better tolerated than solids and also serve to provide needed fluid.
  2. Discourage people from eating high-fat, junk food snack items. Although high-fat foods are energy-dense, fat is not tolerated well at altitude and can worsen the symptoms of AMS. Fat requires more oxygen for metabolism than carbohydrate. Also, even a very lean person has adequate fat reserves to meet an energy deficit on a short-term basis; but the body has limited carbohydrate stores which must be replaced on a daily basis if the person is to stay in good shape. High-fat snack foods such as nuts, cheese, jerky, and sausage can displace preferred carbohydrates. If high-fat foods are tolerated and desired, they should be eaten with carbohydrate foods.
  3. Have available easy-to-digest, high-carbohydrate foods for periods of AMS. Bland, easy-to tolerate foods that might appeal to Witches suffering from AMS include Sunny Boy cereal or oatmeal, instant mashed potatoes, instant rice, Ichiban noodles, Coyote pancakes, crackers, bread, and vanilla pudding.

Prevent Dehydration

  1. Establish a program of regularly-scheduled, assertively-encouraged drinking. Remind Witches to drink even when they are not thirsty. Encourage Witches to drink one bottle of water every 3 hours so that they consume a minimum intake of 5 litres (quarts) of water each day. If the ritual schedule prevents frequent stops to drink, at least two large glasses of water drunk morning and evening can help compensate for limited fluid intake during the day. During periods of nausea, small, frequent sips of liquid are tolerated better.
  2. Provide a variety of non-caffeinated beverages. Warm fluids are well received in cold temperatures. However, tea and coffee have a diuretic effect and promote fluid loss. In addition, excess caffeine can interfere with sleep that is already disrupted at altitude.
