I had a reindeer called Onni
This paper focuses on reindeer stories, as told by reindeer herders who live in northern Finland and train and work with reindeer, both in the context of tourism and competitive racing in Lapland. The stories—ranging from anecdotes and short sequences of events to whole life stories and collected as part of broader participant research focusing on human-reindeer relationships in current reindeer herding in Finland—are used to examine cultural con…
Higher Resting Metabolism Is Associated With Increased Free Triiodothyronine Among Female Reindeer Herders in Northern Finland
Background Thyroid hormones (TH) regulate metabolism and are shaped by environmental factors—ambient temperature in particular. Previous work among indigenous and non‐indigenous populations in Russia revealed that there are seasonal shifts in TH dynamics such that total and free triiodothyronine (fT 3 ) and free thyroxine (fT 4 ) increase during winter. Elevated TH levels in these populations were positively correlated with the elevated resting m…
Total Energy Expenditure and Physical Activity Profiles Among Reindeer Herders and Office Workers of Northern Finland
With the seasonal nature of reindeer herding, February is a period of relative ease following the physically demanding round-up period that lasts from September to January, which may explain these results. Furthermore, large variation in the main variables of eTEE and PAL highlights the need for a larger study population. Therefore, a seasonal assessment of PA and eTEE patterns in this unique population where herders and office workers live close…
Reindeer as Draught Animals in Tourism
Driving with reindeer is an old tradition in northern Fennoscandia that became almost extinct in the last century but that has increased in the past few decades along with tourism. This study investigates the current use of draught reindeer in Lapland, identifies changes since the mid-1900s, and explores the human-reindeer relationship related to this practice, including draught training. We conducted interviews and participatory research with 15…
The impact of winter warming and more frequent icing events on reindeer herder occupational safety, health, and wellbeing
BACKGROUND: Northern Finland, like the rest of the Arctic, has experienced increases in mean annual temperature, the number of winter rains, the number of thaw-freeze days, the number of extremely warm weather events, and a shortened snow season. These changes have produced numerous problems for reindeer herders whose livelihoods rely on a healthy ecosystem with predictable weather patterns. METHODS: We performed a scoping literature review to as…
Brown adipose tissue thermogenesis among a small sample of reindeer herders from sub-Arctic Finland
Introduction Interest in human physiological responses to cold stress have seen a resurgence in recent years with a focus on brown adipose tissue (BAT), a mitochondria dense fat specialized for heat production. However, a majority of the work examining BAT has been conducted among temperate climate populations. Methods To expand our understanding of BAT thermogenesis in a cold climate population, we measured, using indirect calorimetry and therma…
Reindeer herders from subarctic Finland exhibit high total energy expenditure and low energy intake during the autumn herd roundup
High TEE and low caloric intake among herders reflect the extreme demands placed on herders during the annual herd round up. Although TEE DLW was similar between cold climate herders and hot climate farming populations, there are likely differences in how that TEE is comprised, reflecting the local ecologies of these populations
How Reindeer Herders Cope with Harsh Winter Conditions in Northern Finland
Reindeer herding involves hard physical work carried out in a cold climate under variable weather conditions. In the fall and winter, herders’ work in northern Finland includes collecting and moving reindeer herds to round-up sites, working in round-ups, slaughtering and processing meat as well as daily feeding and monitoring of the animals in the field. To study the experiences and perceptions of coping with cold among physically active herders …
Elevated resting metabolic rates among female, but not male, reindeer herders from subarctic Finland
OBJECTIVE: Elevated resting metabolic rates (RMR, kcal/day) are a well-established mechanism for maintaining core body temperature among cold climate populations. A high degree of interindividual variation has recently been noted among circumpolar populations. To further examine RMR variability, we investigated anthropometric and metabolic differences among reindeer herders from subarctic Finland. METHODS: Resting metabolic rates, body mass, body…
Changes in mountain birch forests and reindeer management
Mountain birch forests in the northern areas of Sápmi, the Saami homeland, serve as pastures for semi-domesticated reindeer. Recent reindeer management of the area has, to date, proceeded with little involvement of reindeer herders or their knowledge. To get more in-depth understanding of recent changes, we present together herders’ knowledge and scientific knowledge concerning the impacts of herbivory and climate change on mountain birch forests…
