Blue light emitted by devices like smartphones, computers, and televisions is becoming a major factor disrupting our sleep cycles. Research reveals that a significant number of Americans use electronic devices close to bedtime, contributing to poor sleep quality. Reducing exposure to blue light, particularly in the evening, is a simple yet effective way to help your body prepare for restful sleep.
Circadian rhythms are 24-hour cycles that control essential bodily functions, including sleep. Light is the primary factor that aligns these rhythms with day and night. Historically, exposure to sunlight during the day helped set our body clocks, signaling when to be awake and when to sleep. However, the widespread use of artificial lighting and electronic devices has introduced more light exposure after dark, disrupting these natural cycles.
Blue light, in particular, has the strongest impact on circadian rhythms. During daylight hours, blue light helps us feel alert by stimulating the brain, raising body temperature, and increasing heart rate. But in the evening, exposure to blue light can confuse the body’s internal clock, suppressing melatonin—the hormone responsible for making us feel sleepy. As a result, our brains may remain in “daytime mode,” preventing us from winding down for the night.
Persistent disruption of circadian rhythms can lead to a range of health issues, including metabolic disorders, poor mental health, and increased risk for conditions like depression and anxiety. Furthermore, the inability to sleep well at night affects cognitive performance, mood, and overall well-being. Chronic exposure to blue light in the evening may significantly contribute to these negative health outcomes.
Many common devices in our daily lives emit blue light, including:
- Smartphones and tablets
- Computer monitors and laptops
- Televisions and e-readers
- LED and fluorescent lighting
- Video game consoles
To reduce the effects of blue light on your sleep, here are some practical strategies:
1. Turn off screens before bed: Try to avoid using electronic devices at least two to three hours before bedtime. Reducing screen time helps prevent blue light from interfering with melatonin production.
2. Adjust your lighting: Dim your home’s lights or switch to warmer-toned lighting in the evening. You can also use lamps with red or orange light, which are less likely to impact your circadian rhythms.
3. Night mode settings: Many smartphones and computers have a "night mode" feature that reduces blue light emission. Make use of these features to limit exposure in the hours leading up to bedtime.
4. Blue light-blocking glasses: Special glasses designed to filter out blue light may be helpful for some individuals. These glasses can block or reduce the melatonin-suppressing effects of blue light.
5. Apps for blue light reduction: There are several smartphone and computer apps available that reduce blue light emission, allowing you to use your devices before bed without disturbing your sleep.
6. Create a sleep-friendly environment: If you can’t control light sources in your bedroom, consider using an eye mask to block out ambient light and promote better sleep.

Skin breakouts are often common occurrences during the monsoon season, but not all outbreaks of bumps that occur during this period are traditional cases of acne.
The combination of humidity along with sweat and sebum production makes the skin susceptible to different skin conditions, making it easy to mistake fungal acne for a regular one.
While acne and fungal acne may appear almost identical, the factors that trigger them are not the same. Identifying the right condition early makes it easier to choose the most appropriate treatment and maintain healthier skin in the long run.
It is quite common to experience frequent breakouts during monsoon season. This usually happens due to the accumulation of humid conditions, sweat, and increased oil production.
When sweat mixes with sebum, dead skin cells and skincare products, pores may become clogged, which eventually results in acne. At the same time, the environment also supports the growth of Malassezia, a yeast that naturally lives on the skin.
When it grows excessively, it can trigger fungal acne, medically known as Malassezia folliculitis. Since both conditions tend to flare up during the rainy season, they are frequently confused with one another.

There are several indications which one may use to differentiate between normal acne and fungal acne. Regular acne mostly develops as a combination of blackheads, whiteheads, inflamed pimples, and sometimes painful cysts.
On the other hand, fungal acne presents itself in the form of tiny bumps that usually appear itchy and develop in clusters. These bumps commonly occur on the forehead, chest, shoulders and upper back, especially in areas where sweat tends to collect.
Since regular acne and fungal acne occur due to different reasons, they also require different treatment approaches. Although proper skin care can help in reducing the possibilities of outbreaks, it does not entirely prevent breakouts.
Over-the-counter acne products are usually intended to unclog the pores and control the growth of bacteria causing acne; however, they do not work on fungal infections. In fact, in some cases, using the wrong products can even worsen irritation or allow the breakouts to persist.
Therefore, always consult a dermatologist for targeted skin issues, particularly when acne scars are also a concern. In such situations, many experts may suggest modern treatments such as Harmony XL Pro for personalised results.
This multi-application platform combines numerous energy-based technologies to address specific acne-related concerns and is also used in a variety of aesthetic procedures such as acne-scar removal and overall skin rejuvenation.
A minimal skincare routine can go a long way during the monsoon. Always start with a gentle cleansing after excessive sweating. Choose non-comedogenic moisturisers and make sure not to apply multiple oily or occlusive products that could result in clogged pores.
If you develop a breakout, do not pick or squeeze the acne, as doing so can increase inflammation and the risk of scarring.
In the end, recognising whether a breakout is regular acne or a fungal one is the first step towards appropriate treatment. Although both conditions become more common during humid weather, they are not managed in the same way.
Paying attention to symptoms such as itching, the pattern of the bumps and how the skin responds to treatment can make a meaningful difference.

People think of menopause as just hot flashes and irregular periods, but menopause is more than that.
Perimenopause and menopause can bring a host of emotional and cognitive shifts for many women, including mood swings, anxiety, easily irritated, trouble sleeping, or having what some refer to as “brain fog.”
Perimenopause is the period leading up to menopause that can last anywhere from two to eight years. This is when hormonal changes take place, especially a drop in estrogen.
These hormonal changes also impact neurotransmitters like serotonin and dopamine that are essential for mood, memory, sleep and emotional wellness.
Consequently, a woman can suffer from forgetfulness, lack of concentration, mental tiredness, low energy levels, dry skin, loss of libido and less productivity.

Brain fog can be a frustrating and overwhelming experience during menopause, particularly if a woman is juggling her career, family, ageing parents and personal obligations.
Many women suffer from anxiety symptoms, even if they have no mental health background. Hormonal changes, poor sleep and stress can exacerbate these symptoms.
But not all symptoms are due to the menopause or "normal ageing". Thyroid disorders, vitamin deficiencies, depression and other medical problems can have similar symptoms.
Therefore, if symptoms start to impact life, work, relationships or emotional wellbeing, it is important to seek medical advice and have a proper health check-up.
Management is often comprehensive, and may involve lifestyle modifications. Regular exercise, balanced nutrition, stress management and healthy sleep patterns.
In a few instances, you may additionally be suggested to take Menopausal Hormone Therapy (MHT). As more research is done and preparations of lower doses and greater safety, earlier misconceptions about hormone therapy are gradually decreasing.
Medically, women can make a difference in their quality of lives and manage menopause with greater physical, mental and emotional wellness with early recognition and timely intervention.

Everyone knows that using sunscreen is one of the most important steps for protecting the skin from harmful sun rays, but dermatologists explain that it isn't the only thing you should do to keep your skin healthy. Other daily routines are also important for minimizing sun damage and maintaining healthy skin over time.
Skin is a protective barrier for the body but constant exposure to the sun, pollution, heat and unhealthy lifestyle habits can make this barrier vulnerable.
Once the skin barrier is damaged, the skin is more susceptible to tanning, pigmentation, dryness, sun ageing and other sun damage.
Using a moisturiser every day is a very simple, yet effective habit. A good moisturiser is one that doesn't contain any scents and will support the barrier function of the skin, thereby preventing unwanted water loss from the skin.
Wet and plump skin is resistant to the environment and sun's rays.

Antioxidants are also a best practice for dermatologists. Antioxidants prevent the damage to skin cells by free radicals created by UV exposure, pollution etc.
This protection can help minimize issues like hyperpigmentation, uneven skin tone and premature ageing. Consuming foods that contain antioxidants (such as fruits, vegetables and nuts) can help keep skin healthy on the inside.
Next, hydration is crucial. It's important to keep drinking enough water all day long to keep the skin supple and to allow the skin to repair itself. Moisture also contributes to skin's healing from environmental stress.
Sun protection is also of great importance. Wearing hats or caps, using umbrellas, and wearing clothing that protects against the sun's rays can minimize direct exposure to the sun.
All these are simple actions that serve as a physical barrier and prevent sunburn and long term damage to the skin, particularly between 10 a.m. and 4 p.m. These simple steps provide a physical barrier and reduce the risk of sunburn and chronic skin damage, particularly in the peak hours of 10 a.m. to 4 p.m.

Another focus has been on the connection between gut health and healthy skin, as experts recognize how crucial the role of the gut is in maintaining healthy skin.
Probiotics can potentially improve the gut-skin axis and aid in the healing process and alleviate inflammation in the body. The better the gut environment, the better the skin will be able to recover and the less the exposure to the sun will age the skin.
Some people can use collagen supplements as an added benefit. Collagen is involved in supporting the dermis, the skin's structural component. Keeping collagen high can help promote skin repair and healing mechanisms.
Doctors say while sunscreen is important, long-term skin protection can be achieved through a variety of healthy habits, proper nutrition, hydration and physical sun protection measures, which must be followed daily.
