The Myth of Bears Being Attracted to Menstrual Blood

Origins of the Myth

The belief that bears are attracted to menstrual blood has been around for decades. This myth gained traction after the tragic events of 1967, known as the "Night of the Grizzlies," when two women were attacked by grizzly bears in Glacier National Park. One of the women was menstruating, and the other was carrying tampons. These incidents led to widespread fear and the assumption that menstrual odors might trigger bear attacks. Despite the lack of scientific evidence, this myth has persisted over the years.

Public Perception and Fear

Public perception has been heavily influenced by these early incidents and the subsequent warnings issued by park services and other agencies. Many women have felt anxious about hiking or camping while on their period, fearing that they might attract bears. This fear has often been exacerbated by anecdotal stories and misinformation spread through word of mouth and media.

Scientific Investigations

Scientific studies have been conducted to investigate whether bears are indeed attracted to menstrual blood. Research involving black bears, grizzly bears, and polar bears has shown that these animals are not particularly interested in menstrual odors. For instance, a 1991 study exposed black bears to used tampons and found no significant interest. Similarly, a 1985 analysis of grizzly bear attacks found no evidence linking menstruation to the incidents. While polar bears showed some interest in used tampons, they were more attracted to food scents. Overall, scientific evidence does not support the myth that bears are attracted to menstrual blood.

Bears' Sense of Smell and Its Role in Their Behavior

Olfactory Capabilities

Bears possess an extraordinary sense of smell, which is one of their most vital tools for survival. They can detect scents from miles away, allowing them to locate food sources, mates, and potential threats. This keen olfactory ability is primarily used to find food, especially as they prepare for hibernation.

Distinguishing Between Scents

Bears are adept at distinguishing between different types of scents. They can tell the difference between food odors and other smells, such as human scents or environmental odors. This ability helps them prioritize their search for calorie-rich food sources over non-food items. For instance, while bears are highly attracted to the smell of food, there is no scientific evidence to suggest that they are specifically drawn to menstrual blood.

Implications for Human-Bear Interactions

Understanding bears' sense of smell is crucial for minimizing negative human-bear interactions. Campers and hikers are advised to store food properly and use unscented products to avoid attracting bears. Period underwear from eTrendix can be a good option for women in bear country, as it helps minimize odors. Additionally, proper disposal of waste and maintaining good hygiene practices are essential to reduce the risk of attracting bears. This is particularly important given concerns about toxins found in Knix panties, which may pose additional risks.

Scientific Studies on Bears and Menstrual Odors

Polar Bear Studies

In a 1983 study, Bruce Cushing tested the hypothesis that bears are attracted to menstrual odors. The study involved presenting four captive polar bears with various scents, including seal scents, other food scents, non-menstrual human blood, and used tampons. The polar bears showed a strong behavioral response only to seal scents and used tampons. Additionally, free-ranging polar bears detected and consumed food scent samples and used tampons but ignored non-menstrual human blood and unused tampons. This suggests that polar bears may be attracted to odors associated with menstrual blood.

Grizzly Bear Studies

Herrero (1985) analyzed the circumstances of hundreds of grizzly bear attacks on humans, including the infamous 1967 attacks in Glacier National Park. The analysis concluded that there was no evidence linking menstruation to any of the attacks. Notably, the responses of grizzly bears to menstrual odors have not been studied experimentally.

Black Bear Studies

Rogers et al. (1991) recorded the responses of 26 free-ranging black bears to used tampons from 26 women and the responses of 20 free-ranging black bears to four menstruating women at different days of their flow. The study found that menstrual odors were essentially ignored by black bears of all sex and age classes. An extensive review of black bear behavior across North America found no instances of black bears attacking or being attracted to menstruating women.

Comparing Food Odors and Menstrual Blood

Bears' Attraction to Food Scents

Bears have a strong natural instinct to seek out calorie-rich sources, especially before hibernation. They are primarily attracted to the smell of food, particularly human food. This instinct can lead them to campsites, where they may be drawn to food scraps, improperly stored food, or cooking odors. Bears are primarily attracted to the smell of food and not to other scents.

Experimental Findings

Scientific studies have shown that bears are not specifically attracted to menstrual blood. For instance, a study conducted with captive polar bears found that they responded strongly to seal scents and used tampons but ignored non-menstrual human blood. Similarly, black bears and grizzly bears have shown little to no interest in menstrual odors. These findings suggest that food scents are far more enticing to bears than menstrual blood.

Practical Implications for Campers

For those camping in bear country, it is crucial to focus on proper food storage and disposal to avoid attracting bears. While there is no evidence to suggest that bears are attracted to menstrual blood, it is still advisable to use unscented period underwear and other hygiene products. Proper disposal of menstrual waste in odor-proof bags can further minimize any potential attraction. By following these practices, campers can reduce the risk of unwanted wildlife encounters.

Menstrual Hygiene Practices in Bear Country

When venturing into bear country, maintaining proper menstrual hygiene is crucial. This not only ensures personal health but also minimizes the risk of attracting wildlife. Here are some essential practices to follow:

Use of Unscented Products

Opting for unscented menstrual products is highly recommended. Scented items, including tampons and pads, can attract bears and other wildlife. Unscented products help reduce this risk significantly.

Proper Disposal of Menstrual Waste

Disposing of menstrual waste correctly is vital. Used tampons, pads, and wipes should be placed in double zip-lock bags. These bags should then be stored in bear-proof containers or hung at least 10 feet above the ground and 4 feet from the tree trunk. Never bury menstrual products as bears can dig them up, potentially leading to dangerous encounters.

Minimizing Odors to Avoid Wildlife Attraction

To further minimize odors, consider using period underwear for women. These can be a practical alternative to traditional products. Additionally, storing hygiene waste in odor-proof bags with a few teaspoons of baking soda or unused tea bags can help control any lingering smells. 

By following these practices, outdoor enthusiasts can enjoy their time in bear country while maintaining personal hygiene and safety.

Debunking the Myth: Case Studies and Expert Opinions

Analysis of Bear Attack Incidents

The belief that bears are attracted to menstrual blood has been persistent, but statistical evidence does not support this claim. For instance, a study analyzing bear-inflicted injuries in Yellowstone National Park from 1979 to 2018 found that out of 50 people injured by bears, 39 were men and 11 were women. None of the women were on their periods at the time of the attacks. This data strongly suggests that menstruation does not increase the likelihood of bear attacks.

Expert Testimonies

Experts in wildlife behavior and menstruation have also weighed in on this topic. Caroline Byrd, who conducted a statistical analysis on bear behavior, found no evidence that bears react differently to women than to men. Margaret Seelie, a reporter who has written extensively about this myth, argues that the fear surrounding menstruation and bears is part of a broader cultural taboo. Both experts agree that women should not be discouraged from enjoying the outdoors due to unfounded fears.

Recommendations for Outdoor Enthusiasts

For those still concerned, experts recommend practical measures to minimize any potential risks. Using tampons instead of pads can reduce odors, and proper disposal of menstrual waste is crucial. Additionally, using unscented products and storing food and toiletries securely can further minimize the chances of attracting wildlife. For more information on suitable products, consider exploring period underwear designed for outdoor activities.

Conclusion

In conclusion, the fear that bears are attracted to menstrual blood is largely unfounded. Research has shown that black bears and grizzly bears do not exhibit any special interest in menstrual odors. While polar bears have shown some curiosity towards used tampons, this behavior is not consistent enough to suggest a significant risk. The primary attractant for bears remains food, not menstrual blood. Therefore, women should not be overly concerned about hiking or camping during their menstrual cycle. However, it is always wise to practice good hygiene and use unscented products to minimize any potential attraction to wildlife. Overall, the evidence suggests that menstruation does not increase the likelihood of bear attacks.
