Daylight saving time begins at 2 a.m. on a Sunday in March, when clocks spring forward an hour, effectively robbing most people of an hour of sleep. It is reversed in November when clocks "fall back." Most of America goes through the twice-a-year ritual of changing the clocks for daylight saving time (DST) every year. This change, especially the "spring forward" adjustment, can have a significant effect on our health, beyond sleep disruption.

While designed to extend the duration daylight lasts when awake, the shift can significantly interfere with the body's natural circadian rhythm, regulated by light and darkness exposure.

The body's internal clock is sensitive to light. Morning daylight resets the body's circadian rhythm, and evening darkness triggers the body to release melatonin, a sleep hormone. DST interferes with the evening daylight, delaying melatonin release, which makes it harder to sleep at night. The interference can last for weeks, leading to sleep loss, loss of cognitive function, and increased disease risks.

How Springing Forward Affects Your Health

Disrupted Sleep and Fatigue

The primary impact of DST is the loss of sleep. According to a study by the American Academy of Sleep Medicine, people lose 40 minutes of sleep on the first Monday after the time shift. This sleep deprivation can lead to daytime fatigue, reduced concentration, and compromised cognitive function.

Risk of Heart Attack and Stroke

Studies indicate a remarkable rise in heart attacks and strokes following DST. The American Heart Association suggests that sleep deprivation and sudden circadian rhythm shift can be the cause of this rise, particularly in individuals with existing cardiovascular disease.

Increased Risk of Car Accidents

The facts are confirmed that deadly auto crashes suddenly spike in the days following DST, particularly on morning hours when drivers have not yet adapted to missing one sleeping hour. Sleep deprivation also affects reaction time and alertness, and drowsy driving is a big problem.

Impact on Mental Health

Daylight shift can enhance mental illness such as anxiety, depression, and seasonal affective disorder (SAD). The sudden adjustment in daylight schedules can leave people tired, irritable, and unstable emotionally. Studies indicate that about 10% of SAD victims experience higher symptoms when spring and summer arrive.

Decreased Workplace Productivity

The first Monday after DST sees less "cyberloafing," or surfing the internet free from work, as a new study published in the Journal of Applied Psychology revealed. Employees are less productive, more distracted, and prone to errors due to sleep deprivation and mental lethargy.

How to Prepare for Daylight Saving Time

Since the effects of DST can last for weeks, preparing ahead of time can help make the transition easier. Here are some science-backed tips to minimize the effect:

Gradually Change Your Sleeping Routine

Start adjusting your bedtime 15 to 20 minutes earlier each night a few days before DST begins. Gradually changing your sleeping routine allows your body to adapt more naturally to the new routine, minimizing the shock of an abrupt change.

Boost Morning Sunlight Exposure

Natural light is crucial to maintaining circadian rhythms in sync. Take a sun break during the day, especially the initial week of DST, to help your body acclimate. Exposure to morning sunlight helps reset your internal clock and reduces drowsiness.

Avoid the use of bright screens, such as TVs, tablets, and phones, at least an hour prior to bedtime. Electronic devices emit blue light, which suppresses melatonin production and makes it harder to sleep.

Be Aware of Caffeine and Alcohol Consumption

Caffeine and alcohol will interfere with sleep quality. Try not to take caffeine in the afternoon and do not drink too much alcohol close to bedtime because both will break deep sleep cycles and make it more difficult for your body to adjust.

Establish a Regular Sleep Pattern

Try to sleep and wake up at the same time every day, even on weekends. Maintaining a consistent sleep schedule helps the body's internal clock, so the transition between time changes is less jarring.

Take Short Naps if Necessary

If you're feeling sleep-deprived, a brief nap (20 minutes or less) in early afternoon can improve alertness without interfering with nighttime sleep.

Will the U.S. Abandon Daylight Saving Time?

There has long been controversy over whether or not to eliminate DST. The Sunshine Protection Act, a bipartisan measure that would establish permanent daylight saving time, has stalled in Congress for years.

Daylight saving time is more than a minor nuisance—it has measurable effects on sleep, heart function, mood, and even work productivity. Although efforts to eliminate DST persist, being aware of the effect and taking preventive measures in advance can reduce the ill effects. Being prepared in advance by adjusting sleeping patterns, benefiting from early sun, and sticking to a healthy regimen can smooth the transition and reduce related health hazards for "springing forward."

A deadly case of hantavirus has been confirmed in Israel, while health authorities in the UK and Spain are investigating suspected infections in three individuals, raising fresh concerns over the spread of the rare rat-borne disease.

Hantavirus is primarily transmitted through contact with infected rodents or exposure to their urine, droppings, and saliva, though rare cases of person-to-person transmission have also been reported.

According to the World Health Organization (WHO), eight cases — including three deaths — have been confirmed so far. However, additional suspected and confirmed cases are continuing to emerge across countries.

Despite growing concern, the WHO, the US Centers for Disease Control and Prevention (CDC), and other health agencies have stated that the overall public health risk remains low.

Here’s a look at the countries reporting confirmed and suspected hantavirus cases.

Israel

The case in Israel, reported by the local newspaper Maariv, is believed to have been infected during a stay in Eastern Europe several months ago. It is reportedly not linked to the ongoing outbreak linked to the MV Hondius cruise ship in the Atlantic Ocean.

The patient underwent an antibody test after the symptoms appeared, which showed exposure to hantavirus, the report said. A PCR (polymerase chain reaction) test was then conducted to detect the virus’s genetic material, confirming the infection, it added.

The patient was said to be in stable condition, not in need of intensive care or strict isolation, and was being kept under medical observation.

Details about the patient and the medical center where the diagnosis was made could not yet be published, but have been reported to the country's Health Ministry.

UK

The UK Health Security Agency had confirmed two British cases connected to the outbreak on board the MV Hondius.

One remains in a stable condition in the Netherlands after being evacuated from the ship, the other remains in intensive care after being flown to South Africa last month.

A third case is also being suspected on the remote South Atlantic island of Tristan da Cunha, where the ship stopped in mid-April, the UK HSA said.

In addition, the agency said that two British nationals are self-isolating at home after potential exposure to hantavirus on the cruise ship. The pair had disembarked earlier in the voyage and currently shows no symptoms.

They were part of a group of 30 people from a dozen nations - including seven Britons - who disembarked from the ship at St Helena in the south Atlantic on 24 April, according to operator Oceanwide Expeditions. Four Britons who disembarked on St Helena remain there, BBC reported.

They do not have symptoms but are in contact with health officials. It is understood that medical staff will be sent to the islands to provide support.

Spain

A 32-year-old woman who shared an airplane with a MV Hondius cruise ship passenger who later died of hantavirus is now showing symptoms consistent with the disease, Secretary of State for Health Javier Padilla said while speaking to the media.

The woman ⁠has been taken to a hospital in Alicante, where she ⁠remains in isolation, he added. Her symptoms included coughing and "general malaise".

She is being transferred to a hospital in the city of Alicante where she will be tested ‌for ⁠the virus, with results expected 24 to 48 hours later, according to a statement on the regional health department's website.

Padilla said the woman, a resident of Alicante in the Valencia region, ⁠was sitting two rows behind the cruise ship passenger, but the contact between them "was brief" since the passenger had only been "on ⁠board for a short time" during the flight.

Netherlands

The World Health Organization confirmed that a KLM flight attendant, who was isolating in an Amsterdam hospital with mild symptoms after being in brief contact with a hantavirus patient, has tested negative for the virus.

Her case supports the WHO experts’ theory that the rat-borne disease can only be transmitted person-to-person through prolonged, close contact.

Singapore

Two Singaporean residents who were onboard the MV Hondius cruise ship have tested negative for the virus, the Communicable Diseases Agency (CDA) said today.

The 67-year-old and a 65-year-old had been tested and isolated in the city state. The CDA's National Public Health Laboratory conducted testing on multiple samples collected from the individuals and confirmed that hantavirus, including the Andes virus, was not detected, it said.

“The risk to the general public in Singapore is currently low,” the CDA said.

Hantavirus: The Common Symptoms And How To Reduce Your Risk

According to the CDC, symptoms can appear one to eight weeks after exposure, initially presenting fatigue, fever, and muscle aches. As the disease progresses, it can cause coughing, shortness of breath, and chest tightness as fluid accumulates in the lungs.

The CDC reports that about one-third of individuals who develop respiratory symptoms from the disease may not survive.

You can reduce your risk by eliminating and minimizing your contact with rodents in your home, workplace, or campsite. The best way is to seal holes and gaps in your home or garage and keep the rodents from entering your home. You can also place traps in and around your home to decrease rodent infestation. Clean up any easy-to-get food that could attract rodents.

A deadly case of hantavirus has been confirmed in Israel, while health authorities in the UK and Spain are investigating suspected infections in three individuals, raising fresh concerns over the spread of the rare rat-borne disease.

The case reported from is unlikely to be linked with the ongoing outbreak linked to the MV Hondius cruise ship, currently sailing to the Canary lslands.

The UK is suspecting its third case from a remote South Atlantic island of Tristan da Cunha. Spain is suspecting its first case in a 32-year-old woman who shared an airplane with a MV Hondius cruise ship passenger who later died of hantavirus.

In a good news, suspected cases from Singapore and the Netherlands have reportedly turned negative.

The health officials across 12 countries have joined the WHO in contact tracing efforts. They are:

• Canada
• Denmark
• Germany
• The Netherlands
• New Zealand
• Saint Kitts and Nevis
• Singapore
• Sweden
• Switzerland
• Türkiye
• The United Kingdom
• The United States of America

US CDC Classifies Outbreak As 'Level 3' Emergency

The US Centers for Disease Control and Prevention (CDC) activated its Emergency Operations Centers and has classified the hantavirus outbreak as "Level 3" emergency.

Level 3 is the lowest level of emergency activation and is typical for this stage, ABC News reported.

It also signifies that the risk of the rat-borne virus to the general public remains low. However, the public health agency is actively monitoring the situation.

As per the media report, activating the Emergency Operation Centers signals that an emergency team, consisting of epidemiologists, scientists, and physicians, may have been set up to assist with the response.

No Immediate Public Health Threat To India, says ICMR

After reports of two Indian nationals infected with hantavirus aboard MV Hondius cruise ship, Dr Naveen Kumar, director of the ICMR’s National Institute of Virology (NIV), said that there is "no immediate public health threat” to India.

Dr Kumar said the outbreak appears to be isolated, and that there is currently no evidence of community spread. He stressed that, unlike COVID-19, hantavirus does not spread easily between humans.

“The reported hantavirus cases appear to be isolated ones, and there is no immediate public health threat to India,” he was quoted as saying by news agency PTI.

According to the World Health Organization, the Indian passengers were among a small cluster of suspected infections identified aboard the ship, with health authorities monitoring contacts and taking precautionary measures.

Surveillance Capacity Adequate In India

Kumar said India has sufficient laboratory infrastructure to detect suspected hantavirus cases through the ICMR-NIV and the nationwide Viral Research and Diagnostic Laboratory Network.

“India has diagnostic capacity for hantavirus infection through the ICMR-National Institute of Virology and the nationwide Viral Research and Diagnostic Laboratory Network of 165 labs,” he said.

He said symptoms generally appear one to five weeks after exposure. It includes

fever,

• severe body ache,
• headache,
• fatigue,
• nausea,
• abdominal pain,
• dry cough.

2 Indians Among Crew On MV Hondius Cruise Ship

Two Indians are among 149 people aboard MV Hondius, the expedition cruise ship hit by a deadly hantavirus outbreak that has so far left three passengers dead and eight others infected, according to a BBC report.

The vessel, operated by Oceanwide Expeditions, began its journey from Ushuaia, Argentina, on April 1 and is currently travelling to Spain's Canary Islands on May 10.

According to the World Health Organization, eight people onboard the cruise ship MV Hondius have been infected with hantavirus. Of these, three have died, and five have been confirmed to have the virus. However, more people are likely to be infected, as the disease can take a long time to show symptoms.

The luxury cruise ship was carrying around 150 passengers and crew members from 28 countries.

The nationalities included 38 people from the Philippines, 31 from the United Kingdom, 23 from the United States, 16 from the Netherlands, 14 from Spain, nine from Germany, six from Canada and two crew members from India, BBC reported.

While it is yet not known whether they're infected or not, Dr Puneet Misra, Professor of Community Medicine, AIIMS Delhi, told ANI News Agency that it is likely that the two passengers "might have been exposed to the infection".

He added that "there is no pandemic or epidemic threat" with hantavirus. "The public should not worry. There is no need for panic..."

US President Donald Trump is hopeful that the deadly hantavirus outbreak is very much under control. However, questions are mounting as his administration cut funding to study the rat-borne virus last year.

According to the World Health Organization, eight people onboard the cruise ship MV Hondius have been infected with hantavirus. Of these, three have died, and five have been confirmed to have the virus. However, more people are likely to be infected, as the disease can take a long time to show symptoms.

Speaking to reporters Thursday, Donald Trump sought to reassure Americans that the situation appeared contained.

“It’s very much, we hope, under control,” Trump said during an impromptu appearance near the Lincoln Memorial Reflecting Pool in Washington, DC. The President added that the administration planned to release “a full report” on the incident and said health officials were continuing to study the outbreak closely.

“We’re doing the best we can,” Trump told reporters when asked whether Americans should worry about the wider spread of the virus.

Notably, at least 23 passengers from the hantavirus-affected MV Hondius cruise ship returned home, including several to the United States — and one of them has already fallen ill.

Hantavirus Cases In The US?

The travelers reportedly did not know they had been exposed to the deadly virus when they disembarked during the ship’s stop at Saint Helena, a remote island in the South Atlantic, on April 23.

People in at least five US states — Georgia, Arizona, California, Texas, and Virginia — are reportedly being monitored for possible hantavirus exposure, though none have shown symptoms.

According to Dr. Jay Bhattacharya, Director of the US National Institutes of Health (NIH), “Hantavirus is not spread by people without symptoms, transmission requires close contact, and the risk to the American public is very low.”

CDC Cuts On Hantavirus Research

Behind the public reassurance, however, health authorities are confronting a situation that remains poorly understood — particularly because the Trump administration last year cut funding to study the virus behind the deadly cruise ship outbreak, and also fired scientists in key positions who were tracking viruses.

The Centers for Research in Emerging Infectious Diseases were designed to study viruses that could jump from animals to people, including hantavirus, but in 2025, the National Institutes of Health said the work would not continue.

Further, in its 2026 budget request, on one hand, the Trump administration said it planned to refocus the CDC on outbreak investigations and preparedness; on the other hand, it proposed eliminating about $750 million in preparedness grants that states rely on to cope with natural and man-made disasters, including outbreaks.

It also zeroed funding for the Hospital Preparedness Program, which strengthens healthcare systems to respond to emergencies, saying the program “has been wasteful and unfocused”, the New York Times reported.

Notably, the effects of the Trump administration’s cuts to infectious disease research are also being felt globally. South Africa has the capacity to sequence the hantavirus partly because of investments made by previous US administrations through the President’s Emergency Fund for AIDS Relief (PEPFAR), Dr. Carlos del Rio, an infectious disease expert at Emory University, told reporters.

However, the Trump administration has significantly reduced support for South Africa’s research system and is pulling back funding for PEPFAR.

“I worry that as we disinvest in global health, we’re losing our capacity — our global capacity — to deal with diseases,” Dr. Del Rio said.
