Vertigo

Vertigo: Why the Room Feels Like It’s Spinning

Vertigo is a feeling that you or the room is spinning, even when you are not moving.

It can feel scary, but most of the time it is not dangerous and can get better with simple treatment.

🌪 What is Vertigo?

Vertigo is a type of dizziness.
Instead of just feeling lightheaded, you feel like:

  • The room is spinning
  • You are moving when you are not
  • You may lose your balance

The most common type is called Benign Positional Vertigo (BPPV).

👉 “Benign” means not serious
👉 “Positional” means it happens with certain head movements

🧠 What Causes It?

In most people, the cause is unknown, but it can happen after accidents that injure the neck or head. 

There are two ways to understand why it happens: 

  1. A problem exists in the neck, usually a ‘kink’ in some of the swivel joints of the nexk. This dizziness happens because the neck is connected to the balance centre by special nerve pathways. 
  2. There are tiny pieces of floating debris (possibly calcium carbonate crystals) in the balance centre of the inner ear, known as the labyrinth. When disturbed, these crystal debris upset the balance centre.  

🤢 Common Symptoms

You may feel:

  • Sudden spinning sensation
  • Dizziness when turning your head
  • Nausea (feeling like vomiting)
  • Loss of balance
  • Symptoms lasting seconds to minutes

⚠️ What Triggers Vertigo?

Vertigo often happens when you:

  • Look up or down
  • Turn your head quickly
  • Roll in bed
  • Get up from lying down
  • Lie on one side

👵 Who Gets Vertigo?

  • Can happen at any age
  • More common in older adults
  • Slightly more common in women

⏱ How Long Does It Last?

  • Each episode usually lasts a few seconds to 1 minute
  • It may come and go over weeks
  • Most people improve over time

💡 How to Manage Vertigo

1. Avoid sudden movements

Move your head slowly and carefully.

2. Sit or lie down when dizzy

Prevent falling or injury.

3. Keep your home safe

  • Avoid slippery floors
  • Use support when walking if needed

4. Try special exercises (doctor-guided)

Doctors may teach you simple head movements to:
➡️ Move the crystals back into place
➡️ Stop the spinning

These are called:

  • Epley manoeuvre
  • Brandt-Daroff exercises

🚗 Important Safety Tip

Avoid:

  • Driving
  • Climbing heights
  • Operating machines

👉 Until your symptoms improve

🚨 When to See a Doctor

See a doctor if:

  • Vertigo keeps coming back
  • You cannot balance properly
  • You have frequent vomiting
  • It affects your daily life

❗ Seek Help Immediately If

You also have:

  • Severe headache
  • Weakness in your arms or legs
  • Trouble speaking
  • Double vision
  • Fainting

👉 These may be signs of something more serious

🌟 Final Message

Vertigo can feel frightening, but it is usually treatable and not dangerous.

With the right care:
✔ Symptoms improve
✔ Balance returns
✔ You can go back to normal activities

🧠 Simple Rule to Remember

👉 Move slowly
👉 Sit when dizzy
👉 Get help if unsure

Brandt–Daroff Exercises for Vertigo (Simple Guide)

These exercises help reset your balance by moving tiny crystals in your inner ear back to the right place.

👉 Do this 2–3 times a day
 👉 Each session takes about 10 minutes

🧘‍♂️ Step-by-Step Instructions

Step 1: Start Sitting

  • Sit upright on the edge of your bed
  • Keep your back straight

Step 2: Turn Your Head

  • Turn your head about 45° to one side (slightly looking to the side)

Step 3: Lie Down Quickly

  • Quickly lie down on the opposite side
     (Example: if head turned left → lie on right side)
  • Keep your head angled upward

⏱ Stay here for 20–30 seconds
 👉 Or until dizziness stops

Step 4: Sit Back Up

  • Return to sitting position
  • Wait 20–30 seconds

Step 5: Repeat Other Side

  • Turn head to the other side
  • Lie down on the opposite side
  • Hold again for 20–30 seconds

🔁 How Many Times?

  • Repeat 5 times on each side
  • Do this 2–3 times daily

⚠️ What You May Feel

  • You may feel dizzy during the exercise
     👉 This is normal and expected
    👉 It usually improves after a few days

🚨 Important Tips

  • Move quickly when lying down, but safely
  • Stay calm and breathe normally
  • Stop if symptoms become too severe
  • Do this on a bed, not the floor

🧠 Simple Rule to Remember

👉 Turn → Drop → Wait → Sit → Repeat

Allergic Rhinitis

🌿 What is Allergic Rhinitis?

Allergic rhinitis (AR), also known as nose allergy, happens when your body reacts to things in the air like dust, pollen, or pet fur.

Your body treats these as harmful and releases chemicals that cause irritation in your nose and eyes.

🏠 How to Reduce House Dust Mites at Home

Dust mites cause 90% of allergic rhinitis in Singapore.

🛏 Bedroom Tips

  • Use dust-mite proof covers for pillows and mattresses
  • Wash above covers weekly in hot water above 60 degrees
  • Limit soft toys on the bed (wash them regularly if kept)

🧹 In the Home

  • Mop floors instead of sweeping
  • Remove carpets, heavy curtains, and clutter
  • Reduce the number of stuffed toys in the home, as they trap dust easily

🌬 Reduce humidity

  • Use a dehumidifier and maintain humidity less than 50%
  • Especially in the bedroom

🧠 Simple Daily Routine for AR Control

  • Clean your nose regularly (saline rinse)
  • Keep your room clean and dust-free
  • Avoid known triggers
  • Take medication if prescribed
  • Follow up with your doctor if symptoms persist

🚨 When Should You See a Doctor?

Seek medical advice if:

  • Symptoms do not improve
  • You have poor sleep due to nasal blockage
  • You get frequent sinus infections
  • Symptoms affect your daily life, school, or work

Chronic Back Pain

Treat Your Back with Respect

Your back works hard for you every day. It helps you sit, stand, walk, bend, lift, and sleep. When you treat your back well, it can stay strong and comfortable for longer. Back pain is common, but many cases can be improved by using good posture, moving often, lifting safely, and doing simple exercises. 

Small habits can make a big difference.

Why your back matters

Your back supports your whole body. It also helps protect your spine, which carries messages between your brain and the rest of your body. When your muscles are weak, tight, or overworked, your back can start to hurt.

Here are some good daily habits that can help lower strain on your back:

Everyday habits that help your back

1. Lift with care

When lifting something heavy:

  • bend your knees
  • keep your back straight 
  • hold the item close to your body
  • avoid twisting the body while lifting

A good rule is:
Bend your knees, keep it close, stand up slowly.

2. Do not stay in one position too long

Standing too long, sitting too long, or even walking with poor posture can make your back feel sore.

Try to:

  • change position often
  • stand up and stretch every so often
  • take short walks if you have been sitting for a long time
  • wear low-heeled shoes
  • walk with good posture: chin tucked in, head held high and toes pointing forward

3. Practice good sitting habits

  • use chairs that support you to sit upright
  • knees should be levelled with your hip
  • you should be able to keep both feet flat with thighs parallel to the floor
  • use a rolled-up towel or lumbar support to reduce pressure on your spinal discs
  • avoid hunching, slumping or learning too far forward 

4. Be kind to your back while standing

  • stand tall with your shoulders relaxed
  • spread your weight evenly on both feet
  • if you must stand for a long time, shift your position now and then

5. Sleep in a supportive position

  • sleep on a firm mattress appropriate for your weight
  • side sleepers may bend your knees so they touch on top of each other
  • back sleepers may place a pillow under your knees

Many people find it more comfortable to sleep on their side or on their back with good support.

Back habits to avoid

These habits can put extra strain on your back:

  • bending forward from the waist to lift things
  • twisting your body while carrying something heavy
  • sitting in a slouched position
  • standing still for very long periods
  • sleeping in a poor position with little support
  • using a chair or mattress that does not support your back well

Simple back exercises

These exercises strengthen the back muscles which support your spine. Do these exercises diligently for three months to greatly reduce persistent chronic back pain.

You may do these exercises on a padded surface, well-carpeted floor or yoga mat. Move gently and stop if the pain becomes worse.

  • Do these exercises twice a day, at least 5 minutes.
  • Rest between each exercise.
  • Do not strain.
  • The exercise may be uncomfortable initially, with practice, it will become more natural and enjoyable.

Exercise 5: Pelvic roll

  1. Lie on your back with your knees bent.
