As the weather gets warmer, the risk of heat-related health issues increases, with heat stroke being one of the most severe. Heat stroke can be life-threatening and requires immediate medical attention. While wearing a mask is an important measure to prevent the spread of COVID-19, it can also elevate the risk of heat stroke, particularly when combined with strenuous activity and high temperatures.
Wearing a mask can reduce the body's ability to cool down by limiting the release of hot air during exhalation, leading to a build-up of heat. This effect is exacerbated when masks are worn tightly, restricting breathing and increasing body temperature. As a result, health agencies advise against wearing masks during strenuous workouts or in extremely hot weather.
The risk of heat stroke from mask-wearing is higher for individuals with respiratory issues and underlying health conditions, such as cardiovascular disease, hypertension, obesity, and diabetes. Additionally, older adults and young children are more susceptible. To mitigate the risk, it is recommended to wear masks strategically, opting for cooler times of the day, dressing lightly, staying hydrated, and being aware of heat stroke symptoms.

What You'll Learn
Heat stroke is a medical emergency
Wearing masks, especially for long hours in the heat, can increase the risk of heat-related illnesses like dehydration, heat exhaustion, and heat stroke. Masks can limit oxygen intake and make it harder for the body to cool down by breathing out hot air. While masks are important to prevent the spread of viruses, it is crucial to take precautions to stay safe in the heat.
Heat stroke is a serious and potentially life-threatening condition that requires immediate medical attention. It is the most severe form of heat injury and is considered a medical emergency. If you or someone around you is showing signs of heat stroke, call for emergency medical help immediately. While waiting for emergency services to arrive, move the person to a cooler area, remove any unnecessary clothing, and try to cool them down by applying cold water to their skin or using ice packs in the armpits, groin, neck, and back.
The hallmark symptom of heat stroke is a core body temperature above 104°F (39.4°C). However, fainting may be the first sign, and other symptoms can include dizziness, lack of sweating despite the heat, rapid heartbeat, rapid and shallow breathing, nausea, seizures, confusion, disorientation, behavioral changes, and loss of consciousness. Heat stroke can affect anyone but is more common in older adults, young children, and people with chronic health conditions. It is crucial to act quickly and seek medical help to prevent serious complications or even death.
To prevent heat stroke, it is essential to stay hydrated, wear lightweight and light-colored clothing, avoid excessive sun exposure during the hottest parts of the day, and limit strenuous outdoor activities in high temperatures. Knowing the signs and symptoms of heat-related illnesses is also crucial to taking prompt action and seeking medical attention when needed.

Masks limit oxygen intake
It is a common misconception that masks limit oxygen intake. This is not true for healthy individuals wearing cloth or surgical masks for short periods of time. However, masks can limit oxygen intake for people with underlying respiratory conditions, advanced age, or excess weight. Prolonged use of N95 masks has been associated with reduced breathing in healthy individuals.
The Science Behind Masks and Oxygen Intake
The idea that masks limit oxygen intake stems from the feeling of reduced airflow when wearing a mask. While masks do create a mechanical obstruction that may give the wearer the sensation of having to breathe harder, they do not affect the intake level of oxygen.
Research on Masks and Oxygen Intake
A study by researchers at UH Rainbow Babies & Children's Hospital found that wearing a cloth or surgical mask did not impair the ability of study participants to get air in and out of their bodies. The study measured heart rate, transcutaneous carbon dioxide tension, and oxygen levels in 50 adult volunteers, 32% of whom had a chronic health condition such as asthma. Not a single participant developed a low level of oxygen or a high level of carbon dioxide in the blood while wearing a cloth or surgical mask, either at rest or during exercise.
Expert Opinions on Masks and Oxygen Intake
Dr. Robert Glatter, an emergency room physician at Lenox Hill Hospital in New York, stated that there is no risk of hypercapnia (too much carbon dioxide in the bloodstream) in healthy adults who use face coverings, including medical, cloth, and N95 masks. Carbon dioxide molecules can freely diffuse through the masks, allowing normal gas exchange while breathing.
The Bottom Line on Masks and Oxygen Intake
While masks may create a feeling of reduced airflow, they do not limit oxygen intake for healthy individuals wearing cloth or surgical masks for short periods of time. However, people with underlying respiratory conditions, advanced age, or excess weight may find it harder to breathe due to the added resistance to flow. Prolonged use of N95 masks has been associated with reduced breathing in healthy individuals.

Risk factors for heat-related illness
Heat-related illnesses are a serious concern, and wearing masks can indeed exacerbate the risk. Here are some key risk factors for heat-related illnesses:
- Environmental Factors: Working outdoors in hot and humid conditions, especially in direct sunlight, can increase the risk of heat-related illnesses. This is further worsened by wearing protective clothing or personal protective equipment that does not allow for adequate cooling.
- Physical Activity: Strenuous physical work or activities can generate significant body heat, increasing the risk of heat-related illnesses. This is particularly true if the activities are prolonged without adequate rest.
- Dehydration: Not drinking enough water or fluids can lead to dehydration, which impairs the body's ability to regulate its temperature and cool down through sweating. Dehydration is a significant risk factor for heat-related illnesses.
- Acclimatization: Individuals who are not accustomed to working or spending time in hot environments may be at higher risk. Acclimatization allows the body to adjust and better tolerate heat stress.
- Individual Factors: Certain individuals may be more susceptible to heat-related illnesses due to factors such as obesity, lower fitness levels, age, or underlying medical conditions. Additionally, the use of certain medications and illicit drugs can affect the body's ability to regulate temperature and sweat.
- Caffeine and Alcohol Consumption: Caffeine and alcohol can contribute to dehydration and alter the body's ability to cope with heat stress. This can increase the risk of heat-related illnesses.
- Inadequate Ventilation or Air Movement: Working in areas with poor air circulation or ventilation can slow down the body's ability to release heat, increasing the risk of heat-related illnesses.
- Inappropriate Work Clothing: Wearing dark-colored or tight-fitting clothing in hot environments can hinder heat loss and impair the body's ability to cool down.
- Psychological Factors: Stress, anxiety, or pre-existing psychological conditions can influence an individual's perception of heat and their ability to cope with heat stress.
- Masks: While masks are crucial for mitigating the spread of certain respiratory illnesses, they can also limit oxygen intake and increase the risk of heat-related illnesses, especially in hot and humid conditions.
It is important to recognize these risk factors and take appropriate precautions, such as staying hydrated, taking breaks, and seeking medical attention if necessary, to prevent heat-related illnesses.
