Breaking Update: Here’s a clear explanation of the latest developments related to Breaking News:Morning cold, afternoon heat: Why this weather pattern is hard on the body– What Just Happened and why it matters right now.
Have you noticed that you step out in a sweater in the morning but feel sweaty by afternoon? This confusing weather pattern is common during seasonal change. While it may not seem serious, doctors say it can affect your body more than you realise.
According to Dr Leeni Mehta, MBBS, MD (Internal Medicine), Senior Consultant Physician at Apollo Medical Centre, Marathalli, Bengaluru, sudden temperature changes can disturb the body’s natural balance. Our body constantly works to maintain a stable internal temperature.
When mornings are cold and afternoons turn hot, it takes extra effort for the body to adjust. This stress can weaken immunity temporarily and make people feel tired or unwell.
Many people report mild symptoms such as sneezing, throat irritation, fatigue, or headache during this time. For some, the symptoms last longer or keep coming back.
WHY COLDS, COUGH AND THROAT PROBLEMS INCREASE
Cold mornings and low humidity can dry out the nose and throat. When the lining of the respiratory tract becomes dry, it loses its natural protective barrier. This makes it easier for viruses and bacteria to enter the body.
As a result, people may experience:
- Runny or blocked nose
- Throat irritation
- Persistent cough
- Mild fever
- Bronchitis in some cases
Some individuals may develop a cough that lingers for weeks. Not all coughs or fevers are caused by the same infection. That is why doctors advise against self-medication or changing antibiotics without medical consultation.
THE HIDDEN IMPACT ON BLOOD PRESSURE AND HEART HEALTH
Sudden temperature shifts do not just affect the throat and lungs. They can also influence blood pressure.
Cold weather can cause blood vessels to narrow, which may lead to a temporary rise in blood pressure. On the other hand, heat can cause dehydration and lower blood pressure in some people. These fluctuations can be risky, especially for individuals with:
- Diabetes
- Hypertension
- Heart disease
- Bronchial asthma
People with asthma may notice more breathing difficulty during early mornings. Those with heart conditions should monitor symptoms like chest discomfort, dizziness or unusual fatigue.
HEAT EXHAUSTION AND UNEXPLAINED FEVER: WHAT TO WATCH FOR
Afternoon heat during seasonal transition can sometimes be intense. When the body fails to cool down properly, it may lead to heat exhaustion or, in severe cases, heat stroke.
Symptoms can include:
- High body temperature
- Excessive sweating
- Weakness
- Dizziness
- Headache
- Nausea
Sometimes, people may experience unexplained fever due to heat exposure. It is important not to ignore persistent fever, especially if it lasts more than a few days.
HOW TO PROTECT YOURSELF DURING WEATHER CHANGES
The good news is that simple precautions can help the body adapt better.
Here’s what doctors recommend:
- Stay well hydrated throughout the day
- Eat a balanced diet rich in fruits and vegetables
- Dress in layers so you can adjust to changing temperatures
- Avoid stepping out in peak afternoon heat
- Do not self-medicate, especially with antibiotics
- Seek medical advice if symptoms persist or worsen
If your cold, cough or fever does not improve within a few days, consult a doctor. Early diagnosis can prevent complications.
Seasonal transition may look mild, but the body feels the impact. Cool mornings and hot afternoons can stress the immune system, affect blood pressure, and increase the risk of respiratory issues.
Taking small precautions and listening to your body can go a long way in staying healthy during this tricky weather phase.
