Delta plus variant mystery: What can cause the third Covid wave?

Things in India are looking to normalize and beginning to reopen after a deadly second wave of Covid-19 infections devastated the country in April and May.  There is various thought process from experts who are warning that a third wave could strike in the next few months. The majority of Indians are worried about new variants named delta plus, which is related to the Delta, an existing variant of concern first identified in India last year that was responsible for the deadly second wave.

The million-dollar question is how realistic these fears are. The reality is that future waves are not out of question but their severity and spread depend on several factors. In the past few weeks, the number of average daily cases in India has tapered down to less than 40,000 in recent days which was peak over 420,000 in May. The big drop in numbers has mainly because of strict lockdowns by states.

Many social and political events added to the second wave. If the reopening process are not orchestrated in a controlled fashion the next wave could come sooner than expected.

We are in a very decisive phase and our fate will depend on how we behave. Opening the states in a staggered manner is best. Going aggressive with vaccination and continue with COVID protocols will be the winning strategy. A balanced local and central health protocols could do the magic while severe action on defaulters could be used as a deterrent.

We know that the Delta variant had a killer impact during the second wave. The risk of future mutants in densely populated areas is known and preventive actions should be put in place immediately. There is no clear data around Delta plus but things have changed really fast when the proactive approach is not taken in advance. We need to understand that mutants only emerge when active transmission happening. A lot of research is happening around it take preemptive containment measures by understanding probable sequences.

So far data is indicating that the current vaccine is delivering good results in emerging mutants. India had sequenced 30,000 samples until June, but experts believe more needs to be done because the current vaccine is not a guaranteed long-term solution.

There are multiple cases where vaccinated people have got infected. Some call 3rd wave inevitable and some call it will be a smaller wave but the science is indicating that it will all depend on how effective our existing vaccine is against the new variants.

So, in conclusion, one can say that the key is the vaccinated population in controlling the wave and even allowing it to be formed. The acquired immunity and its efficacy will be crucial in determining the damage the third wave can cause. The required daily dose is upwards of 10 million to get all eligible populations covered by 2021.

The wide range of infection-causing natural antibodies and vaccination combined will provide the ammunition India needs badly to shield against future variants. The problem is the data around it is not very accurate. During the height of infections lot of COVID, infections went unreported. A lot of statisticians around it are guessing the acquired immunity percentage to be around 65%. This number should not be the reason we can take it easy.  

Acquired immunity is immunity you develop over time from a vaccine or exposure to the infection.

Conclusively it can be said that “Third wave is only possible if the new variant beats the barriers of acquired immunity.”

Insomnia in Teens and How to Manage It

Insomnia in Teens and How to Manage It

Sleep is essential for growing teens, yet many struggle to get enough of it. From school stress to social media scrolling, teenagers today face multiple challenges that affect their sleep. One of the most common sleep disorders among adolescents is insomnia—the inability to fall asleep, stay asleep, or wake up feeling rested.

In this blog, we’ll break down the causes, effects, and simple strategies to handle insomnia in teens and how to manage it naturally.

 

What is Insomnia?

Insomnia is a sleep disorder that makes it hard to fall asleep, stay asleep, or get quality rest. Teens with insomnia often feel tired during the day, even if they’ve spent enough time in bed.

There are two main types:

  • Short-term insomnia: Lasts for a few days or weeks, often triggered by stress or changes in routine.
     

  • Chronic insomnia: Occurs at least three times a week for over three months.
     

 

Why Is Insomnia Common in Teens?

Teenagers go through many physical, emotional, and social changes. All these factors can disturb their sleep:

1. Hormonal Shifts

During puberty, the sleep hormone melatonin is released later at night. This shifts the body clock, making teens naturally want to sleep and wake up later.

2. Screen Time

Excessive use of phones, tablets, or laptops before bedtime exposes the brain to blue light, which delays melatonin release and interferes with sleep.

3. Academic Stress

Homework, exams, and performance pressure can cause anxiety and overthinking at night, preventing restful sleep.

4. Caffeine Intake

Energy drinks, tea, coffee, and cola consumed in the evening can make it difficult to fall asleep due to their stimulating effects.

5. Mental Health Issues

Anxiety, depression, and emotional distress are often linked with poor sleep in teens.

 

Signs of Insomnia in Teenagers

  • Difficulty falling asleep at night
     

  • Waking up multiple times during the night
     

  • Feeling tired or sleepy during the day
     

  • Irritability or mood swings
     

  • Trouble focusing in school
     

  • Frequent headaches or stomach issues
     

  • Increased use of stimulants (coffee, energy drinks)
     

 

How Insomnia Affects Teens

Sleep deprivation can harm a teen's physical and mental health. Here are a few ways it affects their well-being:

  • Poor concentration in school
     

  • Weakened immunity
     

  • Increased risk of depression and anxiety
     

  • Weight gain due to hormonal imbalance
     

  • Risky behaviors due to impaired judgment
     

Teens who consistently sleep less than 7–8 hours are more likely to face emotional and academic challenges.

 

Natural Ways to Manage Insomnia in Teens

Thankfully, insomnia doesn’t always need medication. Many teens can improve their sleep with simple lifestyle changes.

1. Set a Regular Sleep Schedule

Encourage going to bed and waking up at the same time every day—even on weekends. This helps reset the body’s internal clock.

2. Limit Screen Time Before Bed

Avoid phones, TVs, and tablets at least 1 hour before bedtime. Use “night mode” or blue light filters if screen use is necessary.

3. Practice Relaxation Techniques

Deep breathing, meditation, gentle yoga, or reading a book before bed can calm the mind and prepare the body for sleep.

4. Watch Food and Drink

Avoid heavy meals, sugar, or caffeine in the evening. A light snack like warm milk, bananas, or almonds can promote better sleep.

5. Get Daily Exercise

Physical activity during the day can improve sleep quality—but avoid intense workouts right before bedtime.

6. Create a Sleep-Friendly Environment

Keep the bedroom cool, dark, and quiet. Use blackout curtains, soft bedding, and remove distractions like phones or bright lights.

 

When to See a Doctor

If your teen’s insomnia lasts longer than 3 weeks or affects their daily life, school, or mood, it’s important to consult a doctor or sleep specialist. Underlying conditions like anxiety, ADHD, or depression might need professional care.

 

Lab Tests That May Help

If your teen complains of constant fatigue or disrupted sleep, you might consider lab tests to rule out medical reasons such as:

  • Thyroid Function Test (for hormonal imbalance)
     

  • Vitamin D & B12 Tests (deficiency can affect sleep)
     

  • Stress Hormone Panel (Cortisol)
     

  • Iron Levels (especially in girls)
     

These tests are available through diagnostic providers like Thyrocare on platforms like SecondMedic.

 

Helping Teens Build Healthy Sleep Habits

As a parent, here’s how you can support better sleep:

  • Encourage open conversations about school pressure or emotional issues.
     

  • Set boundaries for screen use, especially at night.
     

  • Make the home environment calm and supportive before bedtime.
     

  • Lead by example—follow healthy sleep habits yourself.
     

 

Quick Tips for Teens

  • Sleep 8–10 hours every night
     

  • Don’t study in bed
     

  • Use a sleep diary or app to track sleep patterns
     

  • Avoid naps longer than 30 minutes in the day
     

  • Try journaling to clear the mind before sleep
     

 

Conclusion

Teenage insomnia is more common than many people realize. Fortunately, with the right support, structure, and healthy routines, it can be managed without medication.

If your teen shows signs of poor sleep, don’t ignore it. Better sleep leads to better mood, focus, and health.

So, if you’re wondering how to support better sleep for your child, remember to understand insomnia in teens and how to manage it the natural way—with empathy, good habits, and expert care when needed.
