The health benefits and risks of going without underwear are being discussed again as World No Panty Day is observed on 22 June. While the practice is often associated with comfort or personal preference, medical experts say there may be genuine health benefits in certain situations, particularly when it comes to ventilation, moisture control and reducing irritation.
Doctors stress that wearing or not wearing underwear is ultimately a personal choice. However, factors such as fabric type, hygiene habits, exercise routines and individual health conditions can influence whether going without underwear may be beneficial.
For Gauteng residents navigating busy workdays, gym sessions and changing seasonal conditions, understanding the facts behind the trend may help inform healthier lifestyle choices.

What Medical Experts Say About Going Without Underwear
According to gynaecologist and obstetrician Dr Zanele Ngwenya, there is no medical requirement to wear underwear.
She explained that choosing not to wear underwear can improve airflow and reduce moisture build-up in intimate areas.
“Wearing underwear or not wearing underwear is not really a medical necessity. It is more of a personal choice,” Ngwenya said.
She noted that improved ventilation can help maintain a dry environment, which is generally beneficial for intimate health.
Medical experts have long recognised that excessive moisture and heat can create conditions where certain fungal infections are more likely to develop.
World No Panty Day: Why Airflow Matters
The body’s skin naturally produces moisture throughout the day.
In areas where clothing fits tightly against the skin, heat and sweat can become trapped.
According to medical sources, warm and damp conditions may contribute to:
- Skin irritation
- Chafing
- Fungal infections
- Unpleasant odours
- Contact dermatitis caused by certain fabrics or dyes
Allowing greater airflow can help reduce these risks in some individuals.
Experts say this is particularly relevant during Gauteng’s warmer months when high temperatures can increase perspiration levels.
Potential Benefits During Sleep
Doctors suggest that the greatest potential benefits may occur at night.
Ngwenya said sleeping without underwear may allow for increased ventilation and reduced moisture retention while the body rests.
This may be particularly helpful for individuals who experience recurring irritation or discomfort caused by heat and friction.
Sleep specialists often recommend loose-fitting sleepwear to improve overall comfort and temperature regulation.
The same principle applies to undergarment choices.
What About Men?
Medical experts say improved ventilation may also benefit men.
Reduced heat and moisture around the groin area may help lower the risk of certain fungal infections, particularly following exercise or prolonged periods of physical activity.
Some studies have also examined the relationship between tight-fitting undergarments and sperm production.
Because the testicles function best at slightly cooler temperatures than the rest of the body, excessive heat may affect sperm production in some individuals.
While underwear choices alone are unlikely to determine fertility outcomes, doctors say looser clothing may help maintain optimal temperature regulation.
When Underwear Is Still Recommended
Experts caution that going without underwear is not always appropriate.
Clinical psychologist and medical doctor Dr Jonathan Redelinghuys said there are situations where undergarments provide important protection.
“From a health perspective, there may be some benefit to going without undergarments, particularly in reducing moisture and creating a less favourable environment for certain fungal infections,” he said.
“However, it also comes with potential risks, especially if people are sitting on public surfaces without an adequate barrier.”
Undergarments can provide protection by:
- Reducing friction between skin and clothing
- Acting as a barrier between the body and public surfaces
- Absorbing sweat during physical activity
- Helping prevent staining of outer garments
- Improving comfort in certain work environments
For many people, undergarments remain an important part of everyday hygiene and comfort.
Choosing the Right Fabric Matters
For those who choose to wear underwear, doctors consistently recommend breathable fabrics.
Cotton remains one of the most commonly recommended options.
According to Ngwenya, cotton allows better airflow while helping absorb moisture.
Benefits of cotton undergarments include:
- Improved ventilation
- Reduced moisture retention
- Lower risk of skin irritation
- Greater comfort in warm weather
Synthetic fabrics may sometimes trap heat and moisture, particularly during exercise.
However, some modern athletic materials are specifically designed to improve moisture management and may be suitable for active individuals.
Gym and Exercise Considerations
Health professionals say gym environments require special consideration.
Exercise naturally increases sweating and friction.
Wearing suitable undergarments during workouts may help:
- Reduce chafing
- Improve comfort
- Manage perspiration
- Protect sensitive skin
At the same time, overly tight clothing may contribute to discomfort and heat retention.
Experts recommend breathable workout clothing and changing out of damp exercise gear as soon as possible after physical activity.
This advice is particularly relevant during Gauteng’s summer months, when temperatures can rise significantly.
Hygiene Remains Important
Medical professionals stress that personal hygiene remains more important than whether someone chooses to wear undergarments.
Key factors include:
- Regular bathing
- Wearing clean clothing
- Changing out of sweaty garments promptly
- Choosing breathable fabrics
- Maintaining healthy skincare habits
The decision to wear underwear should be based on comfort, lifestyle needs and individual health considerations rather than trends.
What This Means for Gauteng Residents
For Gauteng residents, particularly those who spend long hours commuting, exercising or working outdoors, managing heat and moisture can play an important role in overall comfort and skin health.
Medical experts suggest that increased airflow and breathable clothing may help reduce irritation and moisture-related discomfort in some individuals.
However, there is no universal recommendation to stop wearing undergarments.
The choice ultimately depends on personal preference, activity levels, comfort and individual health needs.
The most important factor remains maintaining good hygiene practices and choosing clothing that supports overall wellbeing.
Frequently Asked Questions
Is it healthier to go without underwear?
Not necessarily. Some people may benefit from increased airflow and reduced moisture, while others may prefer the comfort and protection underwear provides.
Can sleeping without underwear be beneficial?
Doctors say sleeping without underwear may improve ventilation and reduce moisture build-up for some individuals.
What type of underwear do doctors recommend?
Cotton underwear is commonly recommended because it is breathable and helps absorb moisture.
Should I wear underwear while exercising?
Many experts recommend wearing suitable underwear during exercise to reduce friction and improve comfort.
Does tight underwear affect men’s health?
Some studies suggest that prolonged heat exposure may affect sperm production, which is why looser-fitting garments are sometimes recommended.
The Bottom Line
Medical experts agree that wearing underwear is largely a matter of personal preference rather than medical necessity. While increased airflow and reduced moisture may offer benefits for some individuals, factors such as hygiene, fabric choice, comfort and lifestyle remain equally important.
As awareness grows around personal health and wellness, doctors continue to encourage people to make informed choices based on evidence, comfort and their individual health needs rather than social trends.
