Have you ever been in such a deep slip and ended up waking coughing? Chances are, you choked on your own saliva. Yes, it is very much possible. Saliva is a clear liquid produced by your salivary glands that play a crucial role in digestion and oral health. This is because it washes away bacteria and food particles. The body on an average produces about 1 to 2 litres of saliva daily, and a lot of it is swallowed unconsciously. However, when saliva does not flow smoothly down the throat, it can lead to choking, which can be uncomfortable.

Here's all that you need to know about what causes it, and how can you prevent it.

How to recognize the symptoms of choking on saliva?

This happens when the muscles that are responsible for swallowing weaken or malfunction due to health issues and the symptoms may include:

• Gagging and coughing without eating or drinking
• Gasping for air
• Inability to breathe or speak
• Waking up coughing or gagging

What are the common reasons? Why does it happen?

Some of the common reasons include:

Acid Reflux

Acid reflux occurs when stomach acid travels back into the esophagus and mouth, irritating the esophagus and increasing saliva production to neutralize the acid. This buildup of saliva can lead to choking.

Other symptoms of acid reflux:

• Heartburn
• Chest pain
• Nausea

Diagnosis and Treatment:

Acid reflux can be diagnosed via endoscopy or X-rays. Treatment includes antacids to reduce stomach acid.

Sleep-related Swallowing Disorders

When you are sleeping, some abnormal swallowing can occur during that time and it may cause saliva to pool in the mouth and flow into the lungs. This is what leads to choking. This condition is often linked to obstructive sleep apnea (OSA), which causes breathing to pause during sleep.

What are the treatment options?

CPAP machines to provide continuous airflow

Oral mouth guards to keep the airway open

Lesions or Tumors in the Throat

Growths in the throat, whether benign or cancerous, can narrow the esophagus and impede swallowing.

Symptoms to Watch For:

• Visible lump in the throat
• Hoarseness
• Sore throat

Treatment:

Treatment may involve surgery, radiation, or chemotherapy, depending on the nature of the growth.

Dentures That Don't Fit

Dentures can confuse the brain into perceiving them as food and it may trigger excess saliva production and cause choking. The best way to work this out is by consulting a dentist for proper fitting and adjustment of dentures.

Neurological Disorders

Conditions like Parkinson’s disease and ALS can impair the nerves that control swallowing.

Additional Symptoms:

• Muscle weakness or spasms
• Difficulty speaking

Treatment:

Doctors may prescribe medication to reduce saliva production or teach swallowing techniques.

Heavy Alcohol Use

Excessive alcohol consumption can relax throat muscles, allowing saliva to pool and cause choking.

Prevention Tip:

Moderate alcohol intake and sleep with your head elevated.

Talking Excessively

Speaking continuously without pausing to swallow can lead to saliva entering the windpipe.

Prevention:

Take pauses to swallow while talking.

Allergies or Respiratory Problems

Thickened saliva or mucus due to allergies or infections can obstruct the throat, especially during sleep.

Additional Symptoms:

• Runny nose
• Sore throat
• Sneezing

Treatment:

Antihistamines, cold medication, or antibiotics may be prescribed, depending on the underlying cause.

How can you prevent choking from saliva?

In case of sleep apnea, sleep with your head elevated or on your side. You can also try and avoid lying flat right after eating and eat smaller meals to prevent acid reflux. It is also important that you sip water throughout the day to clear any saliva buildup. In severe cases, use over-the-counter medicines for allergies or consult a healthcare provider.

Catherine, Princess of Wales, recently opened up about her cancer recovery. In an interview, the Princess, widely known as Kate Middleton, spoke about how nature helped her navigate the physical and emotional challenges of her illness. She said that spending time outdoors became an integral part of her cancer recovery.

Her experience adds to the growing research into how exposure to natural environments may help the well-being of people battling cancer.

Kate Middleton's Cancer Recovery

Kate announced her cancer diagnosis in March 2024 and said she was undergoing preventive chemotherapy. She completed treatment in September 2024 and announced in January 2025 that she was in remission. She did not publicly disclose the type of cancer she was diagnosed with.

Speaking to nature writer Robert Macfarlane for Country Life magazine, Kate recalled the advice she received during her treatment and recovery. “I was told in hospital that my recovery would not be linear. There will be good and bad days, that it will take time,” she said.

She compared the recovery process to the natural cycles of rest and renewal, adding, “This is the same in nature. It shows us that periods of rest, reflection and renewal are equally as important as moments of growth.”

The Princess said spending time outdoors had helped her reconnect with herself during a difficult period.

“What I feel really passionate about, having had first-hand experience, is approaching illness and recovery through a whole-person approach. Yes, serious illness creates a lot of physical challenges, but there is also a deeper part to all of us,” she said.

“Nature has allowed me to find a deeper connection to my mind, body and spirit,” she added.

Can Spending Time In Nature Help Cancer Patients?

Research suggests that spending time in nature may support psychological well-being among people undergoing cancer treatment.

A 2023 scoping review published in International Journal of Environmental Research and Public Health examined 12 studies involving 2,786 cancer survivors. The studies were based on different forms of nature exposure, including walking outdoors, forest therapy, gardening and even experiencing natural environments through virtual reality.

Researchers reported improvements in several areas, including anxiety, depression, sleep, stress, fatigue and pain. Participants also described nature as an important source of comfort while battling cancer.

Another review published in Seminars in Radiation Oncology in July 2026 examined interventions related to nature for adults diagnosed with cancer. It identified benefits like reduced psychological distress, improved mood, sleep, quality of life and social connection.

The review studied interventions like gardening, forest therapy, physical activity in nature, therapeutic landscapes and nature prescriptions.

A cancer diagnosis affects physical as well as mental health. Patients may experience anxiety, depression, fear of recurrence, uncertainty about the future and emotional exhaustion during treatment and recovery. Spending time in nature can help in several ways:

1. Alleviation Of Stress And Anxiety

Natural environments can give a break from medical appointments, treatment schedules and daily responsibilities. Research suggests that exposure to green spaces may help reduce psychological distress and improve mood.

2. Gentle Physical Activity

Walking in a garden, park or other outdoor space can provide an opportunity for movement. Physical activity, when appropriate to a patient's treatment stage, can help improve physical functioning and reduce fatigue related to treatment.

3. Social Connection

Gardening groups, nature walks and outdoor activities can help patients reconnect with family members, friends and other people. Social support can be valuable during periods of emotional difficulty.

4. Sleep And Relaxation

Outdoor time can encourage relaxation and help establish regular daily routines. Exposure to natural daylight also helps regulate the body's circadian rhythm, which helps sleep-wake pattern.

While research suggests that nature-based activities may support mental health and aspects of quality of life, there is no formidable evidence that spending time outdoors can eliminate cancer risk entirely, shrink tumours or prevent recurrence.

These activities should be viewed as supplementary forms of support, not alternatives to surgery, chemotherapy, radiotherapy, immunotherapy or other prescribed cancer treatments.

It is also important to know that patients may not be able to spend time outdoors during treatment. Fatigue, reduced immunity, mobility limitations, treatment side effects and environmental conditions can affect what is safe and comfortable.

Patients should discuss appropriate physical activity and outdoor exposure with their doctors, especially if they are immunocompromised or recovering from surgery.

Actress Jenny McCarthy has opened up about the lasting effects of her battle with mold poisoning, revealing that the experience has left her with post-traumatic stress disorder (PTSD), anxiety and a fear of being exposed to mold again.

During a recent episode of her podcast, The Jenny McCarthy-Wahlberg Show, the actress spoke about the physical and emotional toll of the illness, the extensive measures she has taken to avoid further exposure and her ongoing recovery.

McCarthy said she had to discard most of her belongings after the suspected exposure, including her clothes and furniture.

"I wound up throwing everything away," she said, adding that she and her husband, Donnie Wahlberg, also left their furniture behind when they moved out of their Los Angeles home.

Although she believes the exposure may have originated in her makeup room, she said she did not want to take any chances.

McCarthy said the experience made her fearful of encountering mold wherever she went. She described having histamine reactions in different places and struggling with everyday activities, including travelling in Ubers, visiting restaurants and boarding airplanes.

The actress also revealed that the prolonged health struggles contributed to a nervous breakdown, leaving her husband worried about her well-being.

Having undergone 11 surgeries in 15 months, McCarthy said she became increasingly afraid that her body would start "falling apart again."

She also described the emotional strain of her treatment, which involved taking around 100 pills a day.

"I find myself crying sometimes," she said, describing how difficult it was to manage the medication and the uncertainty surrounding her recovery.

McCarthy first spoke publicly about her health ordeal in March, describing six months of what she called "living hell."

She previously reported experiencing an infected root canal, pus-filled growths on her eyelids, mouth infections, tooth pain, skin rashes and food allergies.

The actress said a doctor diagnosed her with mycotoxin poisoning in December 2025. She has since described being in remission for seven months and focusing on recovery.

Her efforts to avoid further exposure have also been extensive. In an October 29 podcast episode, she revealed that she had been sleeping in a tent in her backyard because she was afraid of being exposed to mold indoors.

"Because I am paranoid now about basically sleeping anywhere, I live in a tent," she said.

McCarthy has also spoken about concerns over her breast implants and whether they could be associated with mold exposure. During a November 3 podcast episode, she discussed the issue with plastic surgeon Dr Terry Dubrow, who has treated her previously.

What Is Mycotoxin Poisoning And How Can It Affect Health?

Mycotoxins are toxic substances produced by certain molds and other fungi. Exposure can occur through contaminated food or environments, depending on the type of toxin and the route of exposure.

According to the Cleveland Clinic, mycotoxin exposure can affect different parts of the body, including the digestive system, eyes and mouth. Mold exposure can also trigger allergic reactions and worsen respiratory conditions such as asthma.

The health effects depend on factors such as the type of mycotoxin, the amount and duration of exposure, and an individual's susceptibility.

In a bizarre medical case, a 28-year-old US man began seeing his pet cat Luna’s features on human faces after brain surgery. These included almond-shaped eye sockets enlarged pupils and stripes.

If Karl sees Luna first thing in the morning, he continues to see her features on human faces throughout the day, whether in person or online.

However, if he wakes up looking at a human face, he may see that person’s pupils and eye shape on other people’s faces and even on his cat.

According to a case report published in the journal Cortex, Karl experiences a form of palinopsia, in which something seen earlier persists or reappears in subsequent perception. In his case, this causes facial distortions known as prosopometamorphopsia (PMO).

How Did The Condition Begin?

Karl, who lives in the northeastern US, has experienced the condition for two years. It began after surgery to remove part of his right temporal lobe to treat an arteriovenous malformation (AVM), an abnormal tangle of blood vessels connecting arteries and veins that can cause bleeding in the brain.

The right temporal lobe plays an important role in face processing.

"This case of Karl seeing his cat's features in human faces and vice versa demonstrates that individual features can be pulled from memory and influence our ongoing perception," said lead author Brad Duchaine, professor and chair of psychological and brain sciences and principal investigator of the Social Perception Lab at Dartmouth.

More Than 250 People Experience Facial Distortions

Karl is not alone. According to Duchaine's lab, more than 250 people experience facial distortions. Many are mistakenly diagnosed with psychiatric problems.

"We have heard from people who have been told that they had a psychiatric problem and, in some cases, have even been put on antipsychotics, when they are in fact just having visual problems," Duchaine said.

Duchaine also cited a 1986 study published in Cortex. It described a woman who saw a poodle sitting on a passenger's lap while riding a bus. She then began seeing the poodle's face on every passenger. The woman had experienced a stroke nine months earlier.

Unlike that case, Karl sees individual facial features transferred between faces rather than entire faces.

Duchaine used a large language model to turn a line drawing of Karl’s experience into a photorealistic image. He then worked with Karl to refine the visuals featured in the report.

AI-generated images can help researchers understand visual distortions and help patients explain their experiences to doctors, friends and family, Duchaine said, adding that he will continue working with Karl to decode more about the condition.

What Is Prosopometamorphopsia?

Prosopometamorphopsia (PMO) is a rare visual condition in which faces or facial features appear distorted due to changes in the brain's face-processing network. The term combines prosopo (Greek for face) and metamorphopsia (perceptual distortion).

People with PMO may see facial features as:

• Droopy or stretched

• Larger or smaller than normal

• Displaced or out of position

• Distorted in specific parts of the face

Two prominent subtypes are:

• Full-face PMO: The entire face appears distorted

• Hemi-PMO: One half of the face appears distorted

Most cases last days or weeks, although some persist for years. Around 75 case reports have so far been published.
