Humidity In Las Vegas: Causes, Effects, And Tips

Las Vegas is located in the Mojave Desert, known for its extremely low humidity levels. If you’ve ever visited Vegas, you probably noticed how dry the air feels. In this article, we’ll explore the causes of Las Vegas’ low humidity, effects it has on human health and comfort, and tips for dealing with desert dryness during your Vegas vacation.

If you’re short on time, here’s the quick answer: Las Vegas has low humidity due to its desert location. The low moisture causes dry skin, nosebleeds, and throat irritation. Stay hydrated, use a humidifier, and apply lotion to ease discomfort.

What Causes Low Humidity in Las Vegas

Las Vegas is known for its dry and arid climate, characterized by low humidity levels. Several factors contribute to the low humidity in this vibrant city:

Desert Climate

Las Vegas is located in the Mojave Desert, which is known for its extreme aridity. The desert climate is a result of the region’s proximity to mountain ranges that block moisture-laden air from reaching the area.

As a result, Las Vegas experiences very little rainfall throughout the year, leading to low humidity levels.

Rain Shadow Effect

The rain shadow effect also plays a significant role in the low humidity of Las Vegas. The nearby Sierra Nevada and Spring Mountain ranges act as barriers, forcing moisture-laden air to rise and cool. This process causes the air to release much of its moisture before reaching Las Vegas, resulting in dry and low humidity conditions in the city.


The elevation of Las Vegas also contributes to its low humidity. Sitting at an average elevation of around 2,000 feet (610 meters) above sea level, the city experiences a drier atmosphere compared to coastal areas.

As air rises in elevation, it cools and its capacity to hold moisture decreases, leading to lower humidity levels.

Understanding the causes of low humidity in Las Vegas is crucial for residents and visitors alike. With low humidity, the air can feel dry, which can lead to various effects on both people and the environment.

It is important to stay hydrated, moisturize the skin, and take precautions to prevent dehydration and other health issues related to dry air.

Effects of Low Humidity on Health

Low humidity levels can have various effects on a person’s health, ranging from mild discomfort to more serious issues. Here are some of the common effects of low humidity:

Dry Skin and Lip Chapness

One of the most noticeable effects of low humidity is dry skin and chapped lips. When the air lacks moisture, it can cause the skin to lose its natural oils, leading to dryness and flakiness. Similarly, the lips can become dry, cracked, and painful.

To combat this, it is important to moisturize the skin regularly and use lip balm to keep the lips hydrated.


Low humidity can also contribute to an increased risk of nosebleeds. The dry air can cause the nasal passages to become dry and irritated, leading to the formation of crusts and ultimately, nosebleeds.

To prevent this, using a saline nasal spray or applying a thin layer of petroleum jelly inside the nostrils can help keep the nasal passages moist.

Respiratory Irritation and Dry Throat

Inhaling dry air can irritate the respiratory system, causing symptoms such as coughing, wheezing, and a dry throat. Individuals with pre-existing respiratory conditions like asthma may experience worsened symptoms in low humidity conditions.

To alleviate these symptoms, using a humidifier in the room can help add moisture to the air and provide relief.

It’s important to note that the effects of low humidity on health can vary from person to person. Some individuals may be more sensitive to dry air than others. If you experience severe symptoms or prolonged discomfort, it is advisable to seek medical advice.

Impacts on Comfort and Daily Life

Humidity levels in Las Vegas can have several impacts on comfort and daily life. From static electricity to difficulties in sweating and increased thirst, here are some of the effects that high humidity can have on residents and visitors.

Static Electricity

One of the noticeable effects of high humidity in Las Vegas is the increased presence of static electricity. When the air is dry, static electricity can build up more easily, leading to those annoying shocks when touching objects or other people.

This can be particularly frustrating for individuals wearing certain types of clothing or when trying to style their hair. To combat static electricity, using a humidifier in your home or office can help balance the humidity levels and reduce the amount of static electricity in the air.

Difficulty Sweating

In a dry climate like Las Vegas, high humidity can actually make it more difficult for the body to cool down through sweating. When the air is already saturated with moisture, sweat evaporates more slowly from the skin, making it harder for the body to regulate its temperature.

This can result in feelings of discomfort, especially during hot summer months. Staying hydrated and taking frequent breaks in shaded or air-conditioned areas can help mitigate the effects of humidity on sweating.

Increased Thirst

Higher humidity levels can also lead to increased thirst. When the air is humid, moisture in the air makes it harder for the body to evaporate sweat, which is the body’s natural cooling mechanism. As a result, the body may require more fluids to stay hydrated.

It is important to drink plenty of water and other hydrating fluids, especially when spending time outdoors or engaging in physical activities in humid conditions.

Understanding the impacts of humidity on comfort and daily life can help individuals in Las Vegas better prepare for and cope with the effects. By taking proactive measures such as using humidifiers, staying hydrated, and seeking shaded or air-conditioned environments, one can minimize the discomfort associated with high humidity levels.

Tips for Dealing with Low Humidity

Stay Hydrated

When dealing with low humidity, it’s important to stay hydrated. The dry air can cause moisture to evaporate from your body more quickly, leading to dehydration. Make sure to drink plenty of water throughout the day, even if you don’t feel thirsty.

Additionally, you can incorporate hydrating foods into your diet, such as fruits and vegetables with high water content like watermelon and cucumber.

Use a Humidifier

A humidifier can be a great tool for increasing the humidity in your home. These devices release moisture into the air, helping to alleviate dryness and improve your overall comfort. Place a humidifier in the rooms where you spend the most time, such as the bedroom or living room.

You can also add essential oils to the humidifier to create a pleasant aroma while moisturizing the air.

Apply Lotions and Lip Balm

Low humidity can have a drying effect on your skin and lips, causing them to become chapped and uncomfortable. To combat this, make sure to regularly apply moisturizing lotions and lip balms. Look for products that contain ingredients like shea butter or coconut oil, as these can help lock in moisture and keep your skin and lips hydrated.

Don’t forget to protect your skin from the sun as well, as the dry air can make it more susceptible to damage.

Breathe Wet Air

One way to increase the humidity in your immediate surroundings is by breathing in wet air. You can achieve this by taking hot showers or baths, using a steam room or sauna, or even boiling water on the stove. Breathing in the moist air can help alleviate dryness in your nasal passages and throat.

Just make sure to take precautions to avoid burns or scalds when using hot water or steam.

By following these tips, you can better manage the effects of low humidity and improve your overall comfort in dry environments like Las Vegas. Remember to prioritize hydration, use humidifiers, moisturize your skin and lips, and breathe in wet air when possible.


To summarize, Las Vegas’ desert location and rain shadow effect create constant low humidity. This lack of moisture causes health effects like dry skin, nosebleeds, and respiratory irritation. To alleviate discomfort, make sure to drink plenty of water, use a humidifier, and moisturize regularly. With some simple precautions, you can still enjoy everything Vegas has to offer, even with its characteristically arid climate.
