Scientists have found that while greater heat and humidity can slow the spread of Covid-19, longer hours of sunlight is associated with a higher incidence of the disease as per COVID-19 Information & Resources.
The studies, published journal Geographical Analysis, inform the widespread scientific debate over how seasonal changes, specifically warmer weather, might shape the spread of Covid-19.
While research has shown that pathogens such as influenza and SARS thrive in lower temperatures and humidity, little is known about SARS-CoV2, the agent that causes COVID-19.

“There is a lot of pressure to reopen the economy, and many people want to know if it will be safer to do so in the summer months,” said study lead author Antonio Paez, Professor at McMaster University in Canada.
“Restrictions in movement, which have begun to ease around the world, hinge in part on how SARS-CoV2 will be affected by a change in season,” he said.
For the results, the researcher team investigated climate factors in the spread of Covid-19 in several provinces in Spain, one of the countries hardest hit by the pandemic.
They combined and analysed data on reported cases of the disease and meteorological information over a period of 30 days that began immediately before a state-of-emergency was declared.
At higher levels of heat and humidity, researchers found that for every percentage increase, there was a three per cent decline in the incidence of Covid-19, possibly because warmer temperatures curtail the viability of the virus.
The opposite was true for hours of sunshine: more sun meant greater incidence.
The researchers speculate the increase may be related to human behaviour since compliance with lockdown measures breaks down in sunnier days.
They were also surprised to find rates of transmission dropped among more dense populations and in areas with more older adults, suggesting those populations regard themselves as being at greater risk, and so are more likely to adhere to lockdown guidance.
While older adults are more vulnerable to the disease, researchers believe they are less likely overall to contribute to the spread of the disease because they are more apt to be isolated from others because of health or mobility issues.
The researchers stressed that models such as this one show that contagion of COVID-19 declines as a lockdown progresses, possibly to the vanishing point – an argument for maintaining discipline despite the approach of pleasant weather.
Earlier this month, another study published in the journal Transboundary and Emerging Diseases, revealed that Covid-19 could be a seasonal illness with a higher risk in winter.

In the era of computers and smartphones, it is hard to imagine a task that hasnt been made easier by some sort of technology. You all may know how harmful the blue light emitted by computers, smartphones, tablets, televisions, and other electronics is for your eyes. Since the inception of the pandemic, the use of these electronic devices has increased, and we all know it can have multiple undesirable effects on the eye.
Dark circles are formed mostly due to the reflection of the dark maroon underlying orbicularis oculi, a circular muscle around our eye. The dark pigmentation gives you an exhausted look which makes you seem sick or sleep-deprived. The skin around the eye is the thinnest, results in reflection of the said dark maroon underlying orbicularis oculi. The artificial light from the screen of your electronic devices causes a lot of drying, as it steals the moisture from the skin and also causes a breakdown of collagen

How can you deal with the undesirable effects?
*Follow a proper skincare regimen, use a moisturiser rich in vitamins especially C,E, and K. Massage it gently in clockwise and anticlockwise gentle circular movements.
*Apply under-eye cream 40 minutes before going to bed.
*Green tea bags can also help to shrink the blood vessels that will lessen dark circles.
*Catching up on sleep can help reduce the appearance of dark circles.
*Take frequent breaks while using digital devices.
*Reduce overhead lighting to minimize screen glare.
*Keep your eyes an arm's distance away from the screen.
Vivek Singh, CEO and Co-founder of Anveya Living says, "People spend a large portion of the day straining their eyes on computers, phones or tablets. Our eye muscles try to focus and refocus on and off screens which causes strain. There are a few solutions to this problem. Dehydration plays a big role, especially in the area around the eyes. Make sure you pick an eye cream that suits your eye concerns. For example, Anveya has an under eye cream with Vitamin C that helps to reduce puffiness, wrinkles and pigmentation. It basically provides intense hydration, nourishes and protects the thin skin around the eyes".

Commenting on the same, Shilpa Rathi Maheshwari, Founder of I AM LOVE, a Nutraceutical Health and Skincare Brand, said, "Screen time is the latest plague that has been going around and everyone has fallen victim to it; the young and the old. Too much eye strain affects the skin around the eyes, it causes them to age at an accelerated rate. While curbing screen time is one solution, it can't be a solution for people whose livelihood depends on it. Well, you don't have to worry when you have enough protein and collagen in your body. You might need to supplement your body with an increased amount of collagen and protein to negate the damage being done."

Some women say they experienced period changes after getting a Covid-19 vaccination. While the reported changes are short-lived, research into this possible adverse reaction remains critical to the success of the vaccination programme, according to an editorial published in The BMJ.
"A link between menstrual changes after Covid-19 vaccination is plausible and should be investigated," wrote Dr Victoria Male, a reproductive specialist at Imperial College London, in the editorial. Reports of menstrual changes after Covid-19 vaccination have been made for both mRNA and adenovirus-vectored vaccines, she added, suggesting that, if there is a connection, it is likely to be a result of the immune response to vaccination, rather than to a specific vaccine component, she said.
While changes to periods or unexpected vaginal bleeding are not listed as common side effects of Covid-19 vaccination, more than 30,000 such reports have been made to the UK Medicines and Healthcare Products Regulatory Agency (MHRA) surveillance scheme for adverse drug reactions till September 2. However, most people find that their period returns to normal the following cycleand, importantly, there is no evidence that Covid-19 vaccination adversely affects fertility, Male said.

The MHRA states that its surveillance data does not support a link between changes to menstrual periods and Covid-19 vaccines, since the number of reports is low in relation to both the number of people vaccinated and the prevalence of menstrual disorders generally. However, the way in which data is collected makes firm conclusions difficult, Male noted.
She argued that approaches better equipped to compare rates of menstrual changes in vaccinated versus unvaccinated populations are needed, and pointed to the study that the US National Institutes of Health (NIH) has undertaken. Indeed, the menstrual cycle may be affected by the body's immune response to the virus itself, with one study showing menstrual disruption in around a quarter of women infected with SARS-CoV2.
If a link between vaccination and menstrual changes is confirmed, this will allow individuals seeking vaccination to plan in advance for potentially altered cycles, Male contended. In the meantime, clinicians must encourage their patients to report any changes to periods or unexpected vaginal bleeding after vaccination. And anyone reporting a change in periods persisting over a number of cycles, or new vaginal bleeding after the menopause, should be managed according to the usual clinical guidelines for these conditions, she suggested.
