How light can change your mood and mental health

Published

on


It’s spring and you’ve got probably noticed a change within the sunrise and sunset times. But have you furthermore mght noticed a change in your mood?

We have known for a very long time that light affects our well-being. Many of us feel more positive when spring returns.

But for others, big changes in light, similar to originally of spring, can be difficult. For many, shiny light at night can be an issue. Here’s what’s happening.

An ancient rhythm of light and mood

In an earlier article in our series, we learned that light shining into the back of the attention sends “time signals”to the brain and the master clock of the circadian system. This clock coordinates our circadian rhythm.

“Clock genes” also regulate circadian rhythms. These genes control the timing of many other genes activate and off in a 24-hour light-dark cycle.

But how is all this related to our mood and mental health?

Circadian rhythms could also be disrupted. This can occur if there are problems with the event or functioning of the body clock, or if someone is usually exposed to shiny light at night.

When circadian rhythms are disrupted, it increases the chance of some mental disorders. They belong to them bipolar disorder AND atypical depression (a variety of depression where someone is amazingly sleepy and has problems with energy and metabolism).

Light for the brain

Light can also affect circuits within the brain that control mood, like animal studies show.

There is evidence that this happens in humans. A brain imaging study showed exposure to shiny light throughout the day while contained in the scanner modified the activity the world of ​​the brain chargeable for mood and alertness.

Another brain imaging study found the connection between every day exposure to sunlight and the best way the neurotransmitter (or chemical messenger) serotonin binds to receptors within the brain. In several cases, we observe changes in serotonin binding mental disordersincluding depression.

Our mood can improve in sunlight for a lot of reasons related to our genes, brain and hormones.

What happens when the seasons change?

Light can also affect mood and mental health because the seasons change. In autumn and winter, symptoms similar to low mood and fatigue may appear. However, these symptoms often disappear with the arrival of spring and summer. This is known as “seasonality” or, when severe, “seasonal affective disorder“.

What is less known is that for others, the transition to spring and summer (when there may be light) can also include changes in mood and mental health. Some people experience a rise in energy and willingness to be energetic. For some that is positive, for others it can be seriously destabilizing. This can be an example of seasonality.

Most people they usually are not very seasonal. But for many who are, seasonality matters genetic component. Relatives of individuals with seasonal affective disorder are also more prone to experience seasonality.

Seasonality can be more common in conditions similar to bipolar disorder. For many individuals affected by such conditions, the change in day length throughout the winter can trigger a depressive episode.

Counterintuitively, longer days in spring and summer can also destabilize individuals with bipolar disorder in “activated” is a condition during which energy and activity are in excess and symptoms are harder to regulate. Seasonality can due to this fact be serious.

Alexis Hutcheon, who experiences seasonality and helped write this text, told us:

(…) the change of season is like preparing for a battle – I never know what is going to occur, and I rarely emerge unscathed. I’ve experienced each hypomanic and depressive episodes brought on by the change of season, but whether I’m up or down, the one constant is that I can’t sleep. To cope, I attempt to persist with a strict routine, adjust my medications, maximize light exposure, and at all times concentrate to subtle mood changes. This is a time of increased awareness and the need to be one step ahead.

So what happens within the brain?

One explanation for what happens within the brain when mental health changes with the seasons involves the neurotransmitters serotonin and dopamine.

Serotonin helps regulate mood and is the goal many antidepressants. There is a few evidence of seasonal changes in serotonin levels, which could also be lower IN Winter.

Dopamine is a neurotransmitter involved in reward, motivation and movement, and for some it is usually a goal antidepressants. Dopamine levels may additionally fluctuate with seasons.

However, the neuroscience of seasonality is an emerging field that requires further research is required know what is going on within the brain.

How about shiny light at night?

We know that exposure to shiny light at night (for instance, when someone has been up all night) can disrupt someone’s circadian rhythm.

This variety of circadian rhythm disorder is related to a more frequent occurrence of symptoms including self-harm, depressive and anxiety symptoms and deterioration of well-being. This also comes with higher rates mental disorderssimilar to major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (PTSD).

Why is that this? Bright light at night confuses and destabilizes the biological clock. It disrupts the rhythmic regulation of mood, cognition, appetite, and metabolism many Other mental processes.

But persons are very different from one another sensitivity to light. It continues to be a hypothesis that people who find themselves most sensitive to light could also be most prone to disruption of their biological clock brought on by shiny light at night, which consequently results in a greater risk of mental problems.

Where to from here?

Learning about light will help people cope higher with their mental health problems.

By encouraging people to raised adapt their lives to the light-dark cycle (to stabilize their body clock), we can also help prevent conditions similar to: depression AND bipolar disorder appears first.

Healthy light habits – avoiding light at night and looking for light throughout the day – are good for everybody. But they can be especially helpful to humans endangered mental health problems. These include individuals who have a family history of mental health problems or who’ve them night owls (sleeping late and getting up late), that are more prone to biological clock disturbances.

Ant stings can be painful. Here’s how to avoid getting stung this summer (and what to do if it happens)

Published

on

By

The starting of summer is just a couple of days away, and plenty of of us will be looking forward to long, sunny days spent on the beach, by the pool, camping or having a picnic within the park.

Insects love summer too. Most of them right then grow and feed. However, this shared appreciation of the season can sometimes lead to conflict.

Insects have long been preyed upon by many species, including birds, mammals, amphibians, and other insects. Accordingly, quite a lot of defense mechanisms have evolved – perhaps none more familiar to humans than the sting.

Many ants have a stinger on their rear end which they use to deliver venom. It will not be the sting itself that causes pain, but relatively venom. Ant venom accommodates a mix of various chemicals, a few of which have evolved specifically to manipulate the nerve endings in our skin to cause pain.

Let’s take a have a look at the several ant stings chances are you’ll experience this summer in Australia and how to respond.

Bull ants

Bull ants (also often called bulldog ants, jumper ants, or jumper ants) are large for an ant. Some species can grow to length 4 centimeters. They are easily identified by their large eyes, long mandibles (jaws), and aggressive nature.

Their sting is immediate, hot, sharp and unambiguous, similar to that of a honey bee. The intense pain will only last a couple of minutes before being replaced by redness and swelling across the sting site.

There are many differing kinds of bull ants in Australia.

Green-headed ants

Green-headed ants are also called green ants (but not to be confused with green ants). green tree ants northern Australia, which do not sting). Green-headed ants are common and love our lawns.

About Length 6 millimetersthey’re much smaller than bull ants. They can be recognized by their shiny green-purple exoskeleton.

Green-headed ants are frequently less aggressive than bull ants, but they can still deliver a big sting. The pain from a green ant sting can construct up step by step and cause intense, sticky pain.

Fire ants

Fire ants (or imported red fire ants) are native to South America. They were detected first in Brisbane in 2001it probably moved in containers and has since spread across south-east Queensland.

Fire ants are reddish brown and black and range in size from Length 2–6 millimeters.

You will almost certainly encounter fire ants of their nests, which appear like a pile of loose dirt. A hearth ant nest has no obvious entrance, which is way to distinguish it from other similar ant nests.

Disturbing a hearth ant nest will awaken an offended mass of a whole bunch of ants and expose you to being stung.

The initial pain from a single sting seems like an intense, hot itch, although it can be controlled. However, fire ant stings rarely occur in the only digits. One ant can sting multiple times, and plenty of ants can sting one person, which can lead to a whole bunch of stings. A hearth ant sting can cause pus-filled ulcers and scarring in the next days.

If you reside in an area where fire ants are present, it’s price taking a couple of minutes to learn how to do this recognize and report their.

Electric ants

Electric ants is one other nasty random import, coming from Central and South America. Currently limited to Cairns and surroundingsthese are tiny (1.5 millimeters long) yellow ants.

Like fire ants, these ants are frequently defensive, so lots of them will sting without delay. Their sting is more painful than you’ll expect from such a tiny creature. I compare it to being showered with red, hot sparks.

If you think that you see electric ants, please report it Biosecurity in Queensland.

Australian ants should not the worst

You may be surprised to hear that Australian ants don’t even make it to the rostrum when it comes to essentially the most painful ant stings. The winners include: harvester ants (North and South America), which cause severe, sticky pain, comparable to a drill slowly rotating in a muscle – for up to 12 hours.

The gold medal goes to the sting of the South and Central American bullet ant, which has been described How:

Pure, intense, sensible pain. It’s like walking on burning charcoal with a 3-inch nail stuck in your heel.

How to avoid getting stung (and what to do if you do)

Fortunately, the answer is frequently quite simple. Look around before you sit on the bottom or unfolded a picnic blanket, avoiding places where you see ant nests or a lot of foraging ants.

The selection of footwear might also be necessary. In my experience, most stings occur on the feet of those wearing thongs.

If you get stung, generally the situation will improve by itself. The pain often subsides after a couple of minutes (sometimes slightly longer within the case of a green ant sting). The redness, swelling and itching that sometimes follows may last for several days.

In the meantime, if mandatory, ice pack it will help with the pain. If it’s particularly bad, a topical numbing cream containing lidocaine may provide temporary relief. You can get it over-the-counter at a pharmacy.

A small proportion of individuals may experience an allergic response to ant stings. In very severe cases this may include respiratory problems or ingestion. If you or a loved one experiences these symptoms after an ant sting, you need to seek urgent medical attention.

Health matters: WNBA star Napheesa Collier on her commitment to women’s reproductive health

Published

Minnesota lynx

Napheesa Collier will not be only a WNBA superstar for the Minnesota Lynx and a two-time Olympic gold medalist, but additionally the mother of her daughter Mila and an advocate for women’s reproductive health rights.

It recently decided to partner with Opill®, the primary and only every day contraceptive pill available over-the-counter within the United States. This breakthrough represents a major step forward in women’s health care by providing a convenient and accessible contraceptive option. With Opill, women not need to visit health care facilities for prescriptions, making it easier than ever to take control of their reproductive health.

The collaboration relies on Opill®’s long-standing partnership with the Women’s National Basketball Association (WNBA). “One of the reasons Opill® partnered with the WNBA is the great passion of players who use their platform to support causes they believe in,” said Leila Bahbah, leading women’s health brand at Perrigo within the US. “Napheesa exudes this passion, and together we plan to educate and empower people to take control of their reproductive health.”

Collier advocates for girls and says she is willing to have conversations, even in the event that they are difficult. “I just truly believe in everything they do at Opill®. I believe it’s important to talk to people who may become pregnant and to women about the reproductive health and contraceptive options available to them,” Collier tells ESSENCE.

He continues: “I want people to know that if they want contraception, Opill® is a great option. It is the first over-the-counter drug approved by the FDA. It is inexpensive, available. You don’t need a prescription to get it. I think that’s a key thing in today’s climate.”

Collier notes that within the off-season, he tries to travel to various colleges to talk to students about their reproductive freedoms. “Talking about this topic is essential to remove the stigma as it should not be considered a shameful topic or something that should not be discussed openly. My mother was a nurse, so it was casual to talk about it in our house, and I want to pass it on to other people too, so I’m very excited about it,” she says.

In the present political climate, many ladies with daughters are concerned about their future and reproductive health. Collier, included. “Especially because I am the mother of a young girl, it is very important to me to be able to raise her in an atmosphere where she knows her reproductive rights and health, that she has access to affordable health care and contraception if she wants it and that she can ask me these questions and have open conversations.”

Collier continues: “It’s back to education. Again, I think it’s harmful that we can’t have open conversations about birth control and other issues that are usually taboo. I think it’s harmful. I think this does a lot of harm to women. It hurts. This is harmful to our society. Being able to talk about these issues and empowering women to learn about their rights and bodies creates a safer and healthier society.”

Yes, despite what you’ve heard on TikTok, you still need to use sunscreen

Published

By

Summer is nearly here. But as an alternative of using sunscreen, some TikTokers just do that encouraging followers throw it away and forgo sunscreen.

They argue that it’s healthier to forgo sunscreen to get the complete advantages of the sun.

Here’s what the science really says.

How does sunscreen work?

Due to the acute UV environment in Australia, most individuals with pale to olive skin or other risk aspects for skin cancer must accomplish that protect yourself. Applying sunscreen is a key approach to protecting areas that aren’t easily covered by clothing.

Sunscreens work by absorbing or scattering UV rays before they reach the skin and damage DNA or supporting structures corresponding to collagen.

In this photo I (Katie) apply sunscreen only to the appropriate side of my face. Sunscreens absorb and scatter UV light (right side), although it can’t be seen with the naked eye (left side). The photo on the appropriate also shows where sun spots (dark spots) accumulate on my skin and where I do not care to apply sunscreen evenly – under the attention, on the cheek and completely missing the ear.

When UV molecules hit DNA, the surplus energy can damage our DNA. This damage might be repaired, but when the cell divides before the error is repaired, it causes a mutation that may lead to skin cancer.

The energy of the UV particle (photon) causes the DNA strands to break and reconnect incorrectly. This causes a tumor within the DNA strand, which makes accurate copying difficult and might introduce mutations.

The most typical skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Melanoma is less common but most definitely spreads throughout the body; this process known as metastasis.

Two against three At least the Australians will one skin cancer during their lives they usually reconcile 80% all cancers in Australia.

About 99% of skin cancers in Australia are attributable to overexposure to UV radiation.

Excessive exposure to UV radiation also affects the looks of the skin. UVA rays are able to penetrate deep into the skin, where they break down supporting structures corresponding to elastin and collagen.

This causes signs premature agingcorresponding to deep wrinkles, brown or white spots and broken capillaries.

Sunscreen may also help prevent skin cancer

Consistently used sunscreen reduces the danger of skin cancer and slows skin aging.

In Queensland studyparticipants either used sunscreen day by day for nearly five years or continued their usual use.

After five years, the danger of squamous cell cancer was reduced within the day by day group 40% compared to the second group.

Ten years later, the danger of developing invasive melanoma was reduced within the group of individuals taking the drug day by day 73%

Do sunscreens block the health-promoting properties of sunlight?

The answer is a little more complicated and involves a personalised risk-benefit trade-off.

First, the excellent news: spending time within the sun has many health advantages don’t rely under the influence of UV radiation and aren’t affected by the use of sunscreens.

Sunscreens only filter UV rays, not visible light or infrared light (which we feel as heat). Importantly, a number of the advantages of sunlight are obtained through Eyes.

Visible light improves mood and regulates and possibly reduces circadian rhythm (which influences the sleep-wake cycle). myopia (myopia) in children.

Infrared light is being researched as a treatment for several conditions skin, neurological, psychiatric AND autoimmune disorders.

So what is the good thing about exposing your skin to UV radiation?

Sun exposure produces vitamin D, which is crucial for healthy bones and muscles.

Vitamin D deficiency is surprisingly common amongst Australians, peaking in Victoria at 49% in winter and lowest in Queensland at 6% in summer.

Fortunately, individuals who deal with sun protection can avoid vitamin D deficiency taking a complement.

Skin exposure to UV radiation could have advantages independent of vitamin D production, but these haven’t been proven. It may reduce the danger of autoimmune diseases corresponding to multiple sclerosis or cause the discharge of a chemical that may lower blood pressure. However, there aren’t enough details about these advantages to say whether sunscreen can be an issue.

What does this mean for you?

Exposure of the skin to UV radiation may provide some advantages that could be blunted by sunscreens. This determines whether it’s value giving up these advantages to avoid skin cancer how susceptible you have skin cancer.

If you have pale skin or other aspects that increase your risk of skin cancer, try to use sunscreen day by day on all days when the forecast UV index reaches 3.

If you have darker skin that rarely or never burns, you might want to skip using sunscreen on daily basis – although you’ll still need protection when you’re outdoors for prolonged periods of time.

For now, the balance of evidence suggests that it is healthier for people susceptible to skin cancer to proceed using sunscreen, supplementing with vitamin D as needed.
