Do you feel a sense of clarity on some days? Everything you put your mind to, you ace it. But suddenly, the clarity is gone, there is a bit of brain fog. Turns out, it is because of your menstrual cycle.

Even till this date, studies around woman's biology is lacking. However, some recent studies have shown that menstrual cycle causes brain to function a certain way.

For instance, when a woman is ovulating, her sexual desires is at peak, whereas in the beginning of follicular phase a woman might experience clarity in imagination, perception, memory and social abilities. This is also the same time when spatial skills are better, and in the later follicular phase, the anxiety rises.

Studies have also found that during the luteal phase, women feel calmer.

The Hormone Game

In 2022, Pauline Maki along with colleagues from the Gerontology Research Centre studied the fluctuating oestrogen levels and its affects on woman's abilities over the course of each month.

The study involved 16 women who were assessed twice. Once just after period when the oestrogen and progesterone levels were low and once more a week after they ovulated, when the hormone levels were high.

The study found that when these hormones were at peak, the communication abilities in women increased, whereas right after period, the spatial abilities increased.

The reason is in the Hausmann study, this reveals that a woman's tendency to use both sides of the brain becomes more extreme when the hormone levels increases each month.

Studying The Brain

A study led by neuroscientists Elizabeth Rizor and Viktoriya Babenko of the University of California Santa Barbara tracked 30 women throughout their menstrual cycles.

Menstruators experience for about 450 periods during their lifetimes. The fluctuation of hormones during this time impacts behavioural, structural and functional abilities.

To understand this better, the team took MRI scans of their subjects during the three menstrual phases: menses, ovulation and mid-luteal, which occurs after ovulation and lasts till before menstruation.

The results showed that as hormones fluctuate, the gray and white matter in the scans change too. Oestrogen and the luteinizing hormones that spurs ovulation rise and shows a change in white matter in the scan, which suggests a better information transfer.

While for progesterone that rises after ovulation, the tissue increases and cerebrospinal fluid volume decreases. What this means for the brain is yet unknown, but it opens door to more studies, including how menstrual cycle can impact mental health.

Menstrual Cycle And Mood

Turns out that mood swings are not just limited to menstruation or PMS, it changes throughout the menstrual cycle. A menstrual cycle consists of four different phases follicular phase, ovulation, luteal phase, and menses.

Follicular Phase

The follicular phase starts when you begin your menstrual cycle and lasts for about 14 to 21 days, this overlaps with your menses, which is when you are on your period. This means body secretes follicle-stimulating hormone, it does not have a say in your mood, and only helps eggs to grow.

Menstruation

While menses means that uterine blood and tissues comes out through vagina. Right before your period, you may feel blues or sick, an indication that your period is approaching. While on period the feelings of anxiety remains.

Ovulation

Ovulation is when the egg is matured and is released. This is when your oestrogen levels are at peak and it improves your mood, energy and also increases sex drives.

Luteal

The luteal phase is when the follicle left behind by the departing egg secretes progesterone, this increases cravings, lowers anxiety and improves sleep. However, when the egg is left unfertilised, the progesterone levels fall and leads to PMS.

As temperatures rise and warm weather becomes unbearable, it is very important for people to take precautions to protect their own health. Things like applying sunscreen and covering up properly before they leave the house are a must. It also helps to know the symptoms of heatstroke as you will be able to identify it as soon as it happens.

According to the World Meteorological Organization (WMO) 2025 is likely to be one of the three warmest years for global average temperature. This unusual warmth means our bodies might not be fully used to such heat, making it even more important to be mindful of how we're feeling and any potential signs of heat-related illness. Several warnings have been issued globally for people to take proper precautions so that they do not fall victim to the harsh consequences of this heat.

Currently, the temperature in the UK is rising and the National Health Service has issued a warning for people to look out for this unexpected sign if heatstroke. While you may not expect it, signs of heatstroke can appear throughout your body, whether it is in the form of stress and lightheadedness in your arms and legs.

Unexpected Sign of Heatstroke

One lesser-known symptom of heatstroke happens to be cramps in your arms and legs. you might also experience them in your tummy area. So, if you're out in the heat and start to get these kinds of muscle spasms, it could be an early warning sign that your body is struggling with the high temperatures, and you need to take action to cool down and rehydrate. Don't ignore these cramps, especially if they are accompanied by other symptoms of heat exhaustion.

Can Symptoms Related To Heatstroke Be Life Threatening?

The National Health Service (NHS) is highlighting that a condition called heat exhaustion can develop into something much more serious, known as heatstroke, if it's not treated quickly. Heat exhaustion is when your body gets too hot, but it's usually something you can recover from if you take steps to cool down within about half an hour. However, if heat exhaustion progresses into heatstroke, it becomes a medical emergency that requires immediate treatment from healthcare professionals because it can be life-threatening if not addressed promptly. Recognizing the signs of heat exhaustion early is key to preventing it from turning into heatstroke.

Other Symptoms To Be Aware Of

Besides muscle cramps, there are several other important signs of heat exhaustion that you should watch out for when it's very hot. These include feeling unusually tired, experiencing dizziness, having a headache, feeling sick to your stomach or actually vomiting, sweating a lot, and your skin becoming pale and feeling clammy, or even developing a heat rash (though changes in skin color might be harder to notice on brown and black skin). You might also notice that your breathing or heartbeat becomes faster than normal, you have a high temperature, you feel extremely thirsty, and you experience general weakness. It's also noted that children with heat exhaustion might become more irritable than usual.

Undergarments play a very important role in protecting our health. They not only promote hygiene, but they also reduce the chances of chaffing, infections and keep the sensitive areas dry and prevent any unwanted odor. Most women own several pairs of bras, an undergarment used to support breasts, for different occasions. Sports bras are one such variety that women wear when they are doing active work. These bras are different than a daily wear bra as they are more durable and meant to restrict movement to ensure there are no injuries due to sudden movements.

However, a new study suggests that this restrictive movement may be causing women back pain. The research published in the European Journal of Sport Science suggested that these bras, designed to really hold everything in place, might unintentionally put extra pressure on your spine while you're active.

How Does Movement In Sports Bras Affect Women?

To understand how a bra affected breast movement, researchers observed a woman doing activities like running, to see how it affected her breasts, back and spine movement. To understand the difference of movement in each bra, they ran the same test with no bra, a regular day wear bra and a sports bra. By tracking these movements, the researchers were able to see how each type of bra affected her body's mechanics during the activity. This detailed monitoring helped them understand the potential impact of different levels of breast support on other parts of the body, like the spine.

Understanding the Sports Bra Mechanism

Sports bras are specifically designed to limit how much your breasts move around when you're exercising. This is important because excessive bouncing can be uncomfortable and even cause pain, especially if you have larger breasts. Over time, repeated bouncing without proper support can also strain the skin and ligaments in the chest area. Because of these issues, the focus of many sports' bra designs, especially the newer ones, has been on achieving the highest possible level of breast motion control to maximize comfort and support during physical activity.

The researchers pointed out that when your breasts naturally bounce while you're doing activities like running or spinning, the soft tissues around your chest actually help to absorb some of the force that would otherwise go to your joints and spine. However, a sports bra that's too tight and completely stops this natural bounce might prevent this force absorption. As a result, that pressure could then be transferred back to your spine, potentially causing your back muscles to work harder to compensate, which could eventually lead to pain or discomfort in the back

.

Too Much Movement Restriction Can Cause Issues

It is natural for breasts to have movement when one is working out, while too much movement may hurt, allowing some movement can actually be good. This movement allows the surrounding tissues to play a role in shock absorption, protecting the spine and other joints from some of the impact. When a sports bra is so restrictive that it eliminates all bounce, it might disrupt this natural mechanism. This could mean that the forces generated during exercise, which would normally be partially absorbed by the breasts and their supporting tissues, are instead directly transmitted to the back, potentially increasing the load and stress on the spinal structures and muscles.

Used as an umbrella term, dementia is a condition that affects your memory, thinking as well as one's daily activities. While it is concerning to forget things every now and then, dementia essentially chips away at a person’s identity, changing the way they think and behave. Affecting nearly 57 million people worldwide (World Health Organization) in 2021, dementia can occur due to diseases and any sort of injury to the brain. It is the 7th leading cause of death globally and 60-70% of these cases are Alzheimer's disease.

According to the Cleveland Clinic, dementia is caused by damage to your brain, it affects your brain’s nerve cells which blocks the brain’s ability to communicate properly with other parts of your body. They also explained that while dementia cannot be prevented, lifestyle choices can reduce or increase its risk.

Simple and accessible methods, like incorporating exercise into our lives, are seen as very important for helping people maintain a good quality of life as they get older and for reducing the impact of this condition on individuals and their families. While we already know that regular exercise can help keep our brains healthy and lower the chances of getting dementia, new research is pointing towards a specific type of exercise: weight training.

According to a new study published in the GeroScience journal, doing exercises to build muscle might also help protect the brains of older individuals from developing dementia.

How Can Strength Training help Brain Health?

To understand this potential link better, researchers conducted a study with older adults who had already been diagnosed with mild cognitive impairment, which are early signs of potential future dementia. They divided these participants into two groups. One group participated in a weight training program that gradually increased in difficulty and intensity, happening twice a week. The other group, acting as a comparison, did not engage in any structured exercise during the study period. This setup allowed the researchers to directly compare the effects of weight training versus no exercise on the brain health of these individuals.

Can This Help Reverse Early Cognitive Decline?

One of the most hopeful findings of the study was that some of the individuals in the weight training group no longer met the criteria for having mild cognitive impairment by the time the study concluded. This suggests that weight training might have the potential to actually change the course of early cognitive decline.

Researchers believe this happens through several ways: by reducing harmful swelling in the brain, by improving how the body uses sugar which can affect brain health, by increasing helpful substances in the brain that support the growth and survival of brain cells, and by improving blood flow to the brain, which is essential for it to function properly.

Looking ahead, researchers are planning to delve deeper into the specific biological processes at a molecular level that explain how weight training has these protective effects on the brain. They also aim to identify specific markers in the body that could help us understand who might benefit most from this type of exercise and what the ideal exercise routines might look like for different individuals.
