What is Normal BP, Oxygen, and Temperature Range? A Simple Guide

Sometimes we feel tired, dizzy, or unwell  but we don’t always know what’s wrong. That’s why it’s helpful to understand your basic health numbers like blood pressure, oxygen level, and body temperature.

In this simple guide, you’ll learn what’s considered normal and when you should be careful so you can take action at the right time.

What is Normal Blood Pressure (BP)?

Blood pressure tells us how well your heart is pumping blood through your body.

• ✅ Normal BP: 120 / 80 mmHg
  
  
• ⚠️ Low BP: Below 90 / 60 mmHg (you may feel weak, dizzy)
  
  
• ⚠️ High BP: Above 140 / 90 mmHg (can lead to heart problems if ignored)
  
  

🩺 Use a digital BP monitor to check your pressure at home. Sit calmly for 5 mins before testing.

What is Normal Oxygen Level (SpO₂)?

Your oxygen level shows how much oxygen your blood is carrying  very important for breathing and energy.

• ✅ Normal SpO₂: 95% to 100%
  
  
• ⚠️ Below 94%: Could mean a breathing issue
  
  
• ⚠️ Below 90%: Seek medical help immediately
  
  

📍Check it with a pulse oximeter it’s easy and pain-free.

What is Normal Body Temperature?

Body temperature helps detect fever or infection.

• ✅ Normal Temp (Oral): 97.8°F to 99°F (36.5°C to 37.2°C)
  
  
• ⚠️ Above 99.5°F (37.5°C) = Mild fever
  
  
• ⚠️ Above 100.4°F (38°C) = Moderate fever
  
  
• ⚠️ Below 96.8°F (36°C) = Low body temperature
  
  

📍Use a digital thermometer for quick and accurate reading.

Why Should You Know These Numbers?

Because your body talks through them.

By checking BP, oxygen, and temperature at home:

✔️ You can act early

✔️ You avoid panic

✔️ You feel more in control
