00:00Hello, and welcome to your channel. Today, we re-going to talk about something that almost every person experiences multiple times in their life, the common cold, also known as rhinitis.
00:14Why do we catch it so often? What are the real symptoms versus myths? How can you manage it at home? And when should you actually see a doctor?
00:22Stay with us for the next few minutes, and you'll get a complete science-based guide to understanding and managing the common cold.
00:30The common cold is a viral infection of the upper respiratory tract, mainly caused by rhinoviruses, though more than 200 viruses can cause it.
00:39According to Mayo Clinic, adults get an average of two to three colds per year, while children may get even more.
00:46Unlike influenza, the cold is usually mild but still highly contagious.
00:51The cold spreads mainly through airborne droplets when an infected person sneezes or coughs.
00:57Direct contact, like shaking hands and touching contaminated surfaces, and then touching your nose, eyes, or mouth.
01:05That's why schools, offices, and crowded places see rapid spread of colds, especially during colder months.
01:12Symptoms usually appear one to three days after exposure.
01:16According to the CDC, common signs include runny or stuffy nose, sneezing, sore throat, cough, mild headache, fatigue, and body aches, and low-grade fever, more common in children.
01:30Important note, symptoms of the common cold overlap with flu and allergies, but colds are usually milder and self-most colds resolve in seven to ten days.
01:40But sometimes, they can lead to complications like sinus infections, middle ear infections, especially in children, and worsening of asthma or chronic respiratory disease.
01:52Seek medical attention if symptoms last more than ten days without improvement.
01:56Fever rises above 38.5 degrees Celsius or 101.3 degrees Fahrenheit, severe sore throat, shortness of breath, or chest pain occurs, and in children, high fever, ear pain, or unusual drowsiness.
02:11Doctors usually diagnose the common cold based on symptoms and physical examination.
02:16Laboratory tests are not necessary unless complications are suspected.
02:20Blood tests or throat swabs may be done if flu, strep throat, or COVID-19 needs to be ruled out.
02:27There is no cure for the common cold.
02:29Antibiotics do not work against viruses.
02:32Instead, treatment focuses on relieving symptoms.
02:35Medically recommended home care includes rest and adequate sleep.
02:40Drink plenty of fluids, water, herbal teas, clear soups.
02:43Use saline nasal sprays or steam inhalation for congestion.
02:47Gargle with warm salt water for sore throat.
02:50Honey and warm drinks can soothe cough, but not for children under one year.
02:54Over-the-counter medications like paracetamol or ibuprofen for pain and fever, only as advised by a doctor.
03:00Avoid unnecessary antibiotics.
03:03They do not help and may cause resistance.
03:05The common cold is caused by viruses which infect the epithelial cells lining our nose, throat, and sinuses.
03:12These tiny pathogens enter our bodies through our mucosal membranes and then begin multiplying.
03:18Once inside, they trigger our immune system into action, leading to the uncomfortable symptoms we associate with the common cold.
03:25Some common culprits behind the common cold include rhinoviruses, coronabituses, and respiratory syncytial viruses.
03:34These viruses exploit tiny gaps in our defenses, making it all too easy for them to sneak inside our cells and wreak havoc.
03:42Our body temperature rises as part of our immune response.
03:46But the virus has already started hijacking our cells, forcing them to produce more of the virus.
03:52Meanwhile, the immune system rushes to identify and neutralize the threat, leading to inflammation in the affected tissues.
03:59This explains why our nose becomes red and swollen when we have a cold.
04:05As the immune system works overtime to fight off the viral invaders, it also starts producing antibodies,
04:12which helps to stop the virus from replicating further and protects us from future infections.
04:17Even so, the battle between the immune system and the virus can lead to some unpleasant symptoms,
04:23such as coughing, sneezing, and a runny nose.
04:26Ultimately, our immune system wins the war, but not before leaving us feeling miserable for a week or two.
04:32So let's look at some common questions regarding the common cold.
04:36Let's start with, can vitamin C help prevent a cold?
04:39While vitamin C won't keep you from getting a cold,
04:42it may help shorten the duration of cold symptoms if taken regularly.
04:47This means that taking vitamin C supplements or eating foods high in vitamin C,
04:51such as oranges and strawberries, may help reduce the severity and duration of cold symptoms.
04:57However, it's important to note that vitamin C will not prevent you from getting a cold,
05:03and the benefits are only seen if you take the supplement regularly,
05:07not just when you feel like you're getting a cold.
05:10Another myth is,
05:11will antibiotics help me get rid of a cold faster?
05:15Unfortunately, the answer is no.
05:18Antibiotics only work against bacteria, not viruses.
05:23So taking antibiotics for a cold will not help and may even be harmful by contributing to antibiotic resistance.
05:30What are the warning signs of a cold turning into something more serious?
05:35Most colds are mild and resolve on their own within one to two weeks.
05:39However, there are some warning signs that a cold may be turning into something more serious.
05:44These include a high fever that lasts for more than two days,
05:49a cough that persists for more than two weeks,
05:52shortness of breath or difficulty breathing,
05:54a stuffy nose that lasts for more than 10 days,
05:57and a sore throat that gets worse or persists for more than five days.
06:02If you experience any of these symptoms,
06:04it's important to see a doctor as soon as possible.
06:07How long does it take for the body to fight off a cold?
06:09The time it takes for the body to fight off a cold varies depending on several factors,
06:15including the individual's overall health and the severity of the infection.
06:19Generally, it can take anywhere from seven to ten days for the body to clear a cold.
06:24During this time, the immune system is working hard to identify
06:28and eliminate the virus that is causing the cold.
06:31However, some people may experience lingering symptoms for up to two weeks or longer.
06:36During this time, it's important to continue taking steps to support the immune system,
06:41such as getting plenty of rest, drinking fluids,
06:44and avoiding close contact with others to prevent the spread of the virus.
06:49Can a weakened immune system make you more likely to get a cold?
06:53Yes!
06:54A weakened immune system can make you more vulnerable to developing a cold.
06:58When your immune system is compromised,
07:01your body's natural defenses are reduced,
07:03making it easier for viruses to infect your cells
07:07and multiply people with weakened immune systems
07:10are also less able to fight off the infection once it's established,
07:14leading to more severe and prolonged symptoms.
07:17This is why it's important for people with compromised immune systems
07:21to take extra precautions to avoid getting sick,
07:24such as getting vaccinated,
07:26washing their hands frequently,
07:28and avoiding close contact with sick individuals.
07:31Can stress make you more likely to get a cold?
07:34While stress itself won't directly cause you to get a cold,
07:37it can weaken your immune system
07:39and make you more susceptible to getting sick.
07:42When you're stressed,
07:43your body produces hormones like cortisol
07:45that can suppress your immune system.
07:47This means that your body is less able to fight off viruses
07:51and other pathogens that could make you sick.
07:54Additionally, stress can make it harder for your body to recover from illness.
07:57Studies have shown that people who experience high levels of stress
08:01are more likely to develop colds and other respiratory infections.
08:06So while stress doesn't directly cause colds,
08:09it can increase your risk of getting sick
08:11and make it harder for your body to recover.
08:13Can you catch a cold from being outside in the cold weather?
08:17No, you cannot catch a cold simply from being outside in cold weather.
08:22The common cold is caused by a virus,
08:24not by cold temperatures.
08:26However, cold weather can create an environment
08:29that is more favorable for the spread of viruses.
08:32For example, cold temperatures can cause people
08:35to spend more time indoors in close proximity with each other,
08:38which can facilitate the spread of viruses.
08:41Additionally, cold weather can weaken the immune system,
08:45making people more susceptible to getting sick.
08:48However, it's important to note
08:50that cold weather itself does not cause colds.
08:53Rather, it can contribute to the spread of viruses
08:56and make people more vulnerable to getting sick.
08:59Are there any medical conditions that put you at higher risk of getting a cold?
09:03Yes.
09:04Certain medical conditions can compromise the immune system
09:07and make you more susceptible to getting a cold.
09:10For example, people with HIV-AIDS, autoimmune disorders,
09:14diabetes, or chronic obstructive pulmonary disease,
09:17COPD, are at increased risk of getting colds
09:20because their immune systems are weakened.
09:23Additionally, people who undergo chemotherapy or radiation therapy
09:27are also more vulnerable to getting colds
09:30because these treatments can suppress the immune system.
09:33It's important for people with these medical conditions
09:35to take extra precautions to prevent getting sick,
09:38such as getting vaccinated, washing their hands frequently,
09:41and avoiding close contact with sick individuals.
09:44The common cold is a viral infection of the upper respiratory tract
09:48that affects millions of people worldwide.
09:50While it can be annoying and uncomfortable,
09:52it is usually not serious and goes away on its own within a week or two.
09:57Understanding the symptoms, causes, and treatment options
10:00can help you manage the common cold effectively.
10:03Remember to practice good hygiene,
10:05get plenty of rest and fluids,
10:07and consult a healthcare professional if you have any concerns.
10:11Stay healthy and take care.
