The heat waves are rising all over the world and causing a lot of damage. While there are issues of dehydration and heat strokes, studies are suggesting that it might also be responsible for declining mental health, the heat among other things is not only affecting the physicality of human beings but is also having adverse mental health.

Emotional distress: The heat can trigger mood swings, making you feel irritable, anxious, depressed, or even aggressive. You may not be able to predict your reaction, you may be good one moment and then any minor inconvenience will make you angry or sad. Heat often triggers that helplessness in people.

Scattered Focus: Concentrating on tasks becomes a struggle when it's hot. Simple things feel overwhelming, and staying focused is a challenge. While you may be in the zone working on completing something, the heat and sweating will disrupt your flow and then you will not be able to focus on anything other than the heat.

Sleepless Nights: High temperatures, especially at night, disrupt your sleep. This lack of rest can leave you feeling tired, and grumpy, and worsen existing mental health issues. All humans require a comfortable temperature to sleep in, if your body is too wound up or heated up, it will not be able to relax and sleep.

Feeling the Pressure: The heat can pile on stress and make you feel overwhelmed. Concerns about the heat itself or its impact on other aspects of your life can contribute to this feeling. You will feel overwhelmed and unable to work on anything else. The heat makes you feel a certain helplessness, as you cannot stop the sun or turn down the heat.

Body Blues: The heat can cause physical symptoms that affect your mental well-being. Headaches, fatigue, dizziness, and nausea can all contribute to anxiety and low mood. When your body is already fatigued, the urge to do anything else disappears. Your body is drained of energy to function at all and will seek rest and sleep.

Behavioural Shifts: The heat can influence your behaviour. You might act impulsively or have difficulty managing anger. It's like the heat turns up your emotional thermostat. When your body and brain are overheating, it is difficult to think straight and you will grasp at straws to release this energy and pressure off of you.

Some other side effects of the heat are.

• Mental Health Flare-Ups: If you already have a mental health condition, hot weather can worsen your symptoms. Existing depression, anxiety, bipolar disorder, or schizophrenia might feel more intense.
• Heat and Suicide Risk: Studies show a disturbing link between hot weather and increased suicide rates, particularly among men and older adults. Hot weather can be a tipping point for those already struggling.
• Heatwave Hospitalizations: When temperatures soar, people with existing mental health issues may require increased hospitalization. This highlights the need for healthcare systems to be prepared for heat waves.
• Climate Change and Mental Health: Climate change is leading to more frequent heatwaves. Research suggests this could lead to a rise in mental health problems and suicides. Taking action against climate change is crucial for protecting mental well-being.

The association between stress and psoriasis is one of the better-documented cases of the mind and skin connection within dermatology. Consistent across studies, at least in most case series, there is a sizable proportion of patients who experience an important stressful event within the weeks prior to onset or flare-up.

The mechanism is quite clear cut. While the skin is often seen as being passive, it is far from it. Skin itself is immunologically active, having a stress response system of its own, able to produce corticotropin-releasing hormone and cortisol independently from adrenals.

The Mind-Skin Connection

Under prolonged stress, the shift happens in the hypothalamic-pituitary-adrenal axis, leading to a reconfiguration of the immune response towards inflammatory pathways, specifically IL-17 and IL-23 pathway which was targeted by most biologics developed up to now.

Neuro-endocrine innervations lead to the release of neuropeptides such as substance P, attracting inflammatory cells while lowering the threshold of itching. Chronic stress also impairs barrier recovery process, relevant for a disease where the slightest skin damage leads to a plaque formation.

So whenever a patient claims stress caused her flare-up, she is describing an actual immunological phenomenon.

And the cycle, which is the part that entraps people.

And here lies the complexity, the place where I believe most of the articles end prematurely.

Stress Aggravates Psoriasis

Then the psoriasis becomes the source of stress. Highly visible plaques on hands, scalp or face are hard to hide within a culture where we greet, eat and worship with our hands. Patients start dressing in ways that conceal their plaques. They avoid public showers, salons, wedding events. Itch affects their sleeping habits, causing higher inflammation levels.

Then come the questions patients do not usually disclose unless specifically asked. The shame. Some patients have experienced people wondering whether they could catch the condition. Some of them have been asked to leave the salon where they went. This is not just an annoyance, but also a hurt, directly feeding back into the loop.

The prevalence of depression and anxiety in psoriasis is much higher than among healthy people. Moreover, these problems cannot be explained only by a reaction to one's appearance. The same inflammatory mediators, which cause psoriasis, are now associated with depression. Therefore, psoriasis and depression can be two symptoms of one inflammatory condition.

What Really Helps?

Here I need to be very careful, since the idea that stress provokes psoriasis can be twisted into the belief that the patient has caused his/her own illness. But it is not true and is insulting to people suffering from the condition. It should be said again that psoriasis is a genetically based immune disorder. It is stress that exacerbates the disease.

Within this framework, stress management techniques are useful and there is the trial evidence for their efficiency. In one study, mindfulness-based intervention helped to improve the outcome and even accelerated clearance with phototherapy.

Physical exercise has an independent anti-inflammatory effect and treats metabolic syndrome associated with psoriasis. Sleeping is an obligatory factor because sleep deprivation increases the level of cytokines that we need to suppress. Cognitive behavioral therapy helps people to cope with itching-scratching cycle.

There is no doubt that alcohol and smoking make psoriasis worse, although they are usually used as a coping strategy in response to stress. They serve as an additional burden on health.

All of this is important but not an alternative to treatment. Topicals, phototherapy, systemic medications, and biological agents still remain the core of the treatment regimen. Stress management is only an adjunct, and I always remind my patients about it so that they never feel guilty for taking medicine.

Treat The Whole Person

Now I ask two questions at each review of psoriasis. How much of the body surface area is affected and how much of the person's life does it occupy. The answer to these questions often does not coincide.

I saw patients with rather small involvement of the skin surface, whose psoriasis completely ruined their self-esteem. And I met patients with large involvement who coped with the disease perfectly.

Body surface area does not measure suffering. If we treat only what we can see, we will treat half of the disease.

H1N1 cases are rising across several Indian states, with infections, hospitalisations and deaths being reported. However, the Indian Council of Medical Research (ICMR) has said the increase is not unusual and that no new strain is driving the current rise.

The ICMR has clarified that the circulating Influenza A (H1N1) pdm09 viruses have been present in India since 2025 and that no new strain has been identified.

ICMR Director General Dr Rajiv Bahl has said H1N1 accounts for nearly 98% of Influenza A cases currently detected in India, while H3N2 accounts for around 2-3% of cases.

Health authorities have urged people not to panic but to remain alert, particularly if symptoms become severe or persist.

States Reporting H1N1 and Influenza Cases

Delhi

Delhi has reported 138 new H1N1 cases in the last 24 hours, taking the cumulative number of H1N1 cases this year to 2,446, the Delhi government said on Wednesday.

The total number of Influenza A cases has reached 3,177 as the city continues to see a rise in seasonal influenza infections.

Maharashtra

Maharashtra is witnessing a significant surge in Influenza A (H1N1) cases, with the 2026 tally already surpassing the total recorded throughout the previous year.

As of August 21, the state had reported 1,109 H1N1 cases, compared with 942 cases in all of 2025.

Mumbai and Pune remain the primary centres of reported infections, together accounting for around 65% of the state's total cases.

Uttarakhand

Uttarakhand has reported 49 confirmed H1N1 cases and five deaths as of late August 2026, prompting a heightened health alert.

The state has also reported 103 dengue cases, including 49 confirmed cases from Dehradun.

Karnataka

Karnataka has recorded 4,212 laboratory-confirmed influenza cases, including H1N1 cases, across 32 districts since January, with the majority of active cases concentrated in Bengaluru.

That compares with 4,583 cases in 2025 and 3,903 cases in 2024.

Kerala

Kerala has reported 7,421 influenza cases and 88 deaths this year, with most fatalities reported among people over 50.

These figures refer to influenza overall and should not be treated as H1N1-specific cases or deaths.

What Does H1N1 Usually Feel Like?

According to the Ministry of Health and Family Welfare, fever and systemic symptoms generally last around three days, although they can persist longer. Cough and weakness may continue even after the fever settles.

Dr GC Khilnani, Chairman, PSRI Institute of Pulmonary, Critical Care & Sleep Medicine, PSRI Hospital, New Delhi, told HealthandMe that common symptoms include body aches, sore throat, headache and fever, which can sometimes be high-grade.

Nausea, vomiting and occasional chest pain may also occur. The illness can be relatively short-lived and may last around three to five days in many cases.

H1N1 Red Flags You Shouldn't Miss

Certain symptoms should not be managed casually at home. These include:

Fever accompanied by breathlessness

Chest pain

Increasing weakness

Confusion

Bluish lips or nails

A noticeable fall in oxygen levels

These symptoms may indicate more serious respiratory involvement and require prompt medical assessment.

Who Needs to Be Particularly Cautious?

Although influenza can affect people of any age, certain groups are more likely to develop severe illness. These include young children, older adults, pregnant women and people with asthma or other chronic lung conditions, heart disease, diabetes or kidney disorders.

People with weakened immune systems are also at greater risk of complications. This includes cancer patients, particularly those receiving chemotherapy or other treatments that suppress immunity.

“An oncology patient may not always develop a dramatic set of symptoms at the beginning. Chemotherapy can affect blood counts and reduce the body's ability to mount an effective response to infection. That is why a new fever or respiratory symptom during treatment deserves earlier attention than it might in an otherwise healthy person,” says Dr Ankur Nandan Varshney, Sr. Medical Oncologist, Medanta Hospital, Noida, told HealthandMe.

Which Tests Are Actually Needed?

Not everyone with a cough and fever needs an H1N1 test. Testing is generally guided by symptoms, severity, risk factors and the clinical situation.

If the doctor suspects influenza and confirmation is needed, testing is usually done using a respiratory sample collected through a nasal or nasopharyngeal swab. Molecular methods such as RT-PCR can identify the influenza virus and help confirm the diagnosis.

“For a cancer patient, I would not look at the H1N1 report in isolation. A CBC with differential, particularly the neutrophil count, can be clinically important during chemotherapy. Depending on symptoms, oxygen saturation and examination findings, the doctor may also recommend a chest X-ray or CT scan to look for pneumonia or other lung complications,” explains Dr Varshney.

Don't Wait for Symptoms to Become Severe

People who are more susceptible to complications should seek medical advice early rather than relying on repeated home tests or taking medicines without guidance.

While many seasonal influenza infections improve on their own, individuals with weakened immunity or other underlying risk factors need closer monitoring and should contact their doctor promptly if symptoms appear or start getting worse.

“Especially in patients undergoing cancer treatment, the aim should be to identify deterioration early rather than wait until breathing becomes difficult,” said Dr Varshney.

How Can You Prevent H1N1 Infection?

Simple precautions can help reduce the spread of seasonal influenza:

Wash your hands regularly with soap and water.

Cover your mouth and nose when coughing or sneezing.

Avoid close contact with people who are sick.

Stay home when experiencing flu-like symptoms.

Improve ventilation in shared indoor spaces.

Avoid touching your eyes, nose and mouth with unwashed hands.

Amid a significant surge in H1N1 cases in India, experts say the flu can affect more than just the respiratory system—it can also cause eye symptoms.

H1N1, a strain of influenza A virus, is usually associated with fever, cough, sore throat, body ache, fatigue and other respiratory symptoms. It spreads mainly through respiratory droplets when an infected person coughs, sneezes or talks. However, influenza can sometimes affect areas beyond the respiratory system, including the eyes.

Some people may develop watering, redness, irritation, photophobia or dryness during a flu infection. While these symptoms may improve as the flu resolves, sudden changes in vision should not be ignored.

How Does H1N1 Affect the Eyes?

Speaking to HealthandMe, Dr. Sfurti Maan, Senior Consultant, Internal Medicine, Shalby International Hospital, said that in most cases, eye symptoms are mild and settle with appropriate care. One of the more noticeable problems is viral conjunctivitis.

“The eyes may become red and watery, with burning, irritation or mild discharge. More intense inflammation may cause swelling of the eyelids or conjunctiva,” the expert said.

A person may also develop light sensitivity or general discomfort in the eyes.

Another possible finding is a bright-red patch on the white portion of the eye. This is called a subconjunctival hemorrhage and can sometimes occur after severe coughing or vomiting.

When Should You See A Doctor?

Most H1N1-related eye problems are limited to conjunctivitis. However, rare cases of deeper eye inflammation, including uveitis, retinitis and optic nerve involvement, have also been reported. These complications are uncommon but can affect vision.

“If someone has influenza and develops persistent blurred vision, severe eye pain, marked sensitivity to light or a sudden drop in vision, that should not be treated as routine conjunctivitis. These symptoms need an eye examination,” Dr. Sfurti said.

Dr. Poninder Kumar Dogra, Senior Consultant, Ophthalmology at ShardaCare – Healthcity, said people with influenza should see an ophthalmologist if they experience:

• Sudden loss of vision

• Blurred or double vision

• Flashes of light

• An increase in eye floaters

• Vision problems when looking close up

• Substantial eye pain

• Intense redness or redness around the eye

• An unusual increase in photophobia with discharge

What About Contact Lens Wearers?

Contact lens wearers may develop eye pain, redness and changes in vision. Contacts should not be worn, and an eye examination should be arranged until the eyes have been investigated and an ophthalmic practitioner says they can be worn again.

Fluid loss, dehydration and fever during the flu can cause dryness and discomfort. Various medications may also cause dry eyes.

How Can You Prevent Eye Symptoms?

Annual flu vaccination is one of the key ways to reduce the risk of influenza. Others include:

• Good hand hygiene,
• covering the mouth and nose while coughing or sneezing,
• avoiding close contact with people who are sick
• staying home when unwell.

Dr. Sfurti advised people with flu symptoms to also avoid touching or rubbing their eyes, particularly with unwashed hands. If conjunctivitis is present, sharing towels, tissues, pillows or personal eye-care products should also be avoided.

“It is important not to panic just because H1N1 can affect the eyes. Serious ocular complications are very rare. The important thing is to recognise the warning signs. If there are only redness, watering and mild irritation, it is usually not a reason for alarm. But any significant change in vision deserves prompt medical attention.”

Dr. Poninder told HealthandMe that antibiotic drops or steroids should never be self-prescribed without seeing an ophthalmologist, as they can potentially delay diagnosis or affect the diagnosis of another condition.

Redness with a slight amount of discharge, discomfort or irritation with transient dryness that gradually resolves may not require an ophthalmologist referral. However, sudden loss of vision, intense pain, extreme redness and progressing inflammation should be checked.
