Earth will be closest to the Sun today: PSI

The Planetary Society of India (PSI) said on Monday that the Earth will reach its closest point to the sun on Tuesday.
PSI Director N Sri Raghunandan Kumar said in a press release that the earth revolves around the sun in an elliptical orbit. Therefore, at a certain point in time, the earth will be closest to the sun.
Therefore, he said that at 12:09 on Tuesday noon, the earth will reach the closest point to the sun in an annual elliptical orbit of 0.9833 AU, which is 14,70,99,586 kilometers from the sun.
In astronomy, this phenomenon is called “perihelion.” At 12:41 pm on July 4 this year, the earth will be located at the aphelion point 1.0167 AU (15,20,96,155 kilometers) from the sun, which is the point furthest from the sun.
In other words, due to perihelion, the earth will be 49,96,569 kilometers closer to the sun in its orbit than on July 4.
Mr. Kumar said that it is generally believed that the distance from the earth to the sun determines the season or temperature on the earth. However, it is not.
When the earth revolves around the sun, the axial tilt of its axis (approximately 23.5 degrees) regulates the seasons on the planet earth, with one hemisphere facing away from or facing the sun.
At the beginning of the year, in most countries in the northern hemisphere, January is winter, and the earth is closest to the sun in early 2022.
And now is the summer in the southern hemisphere countries. Also in July, when the earth is at the farthest position from the sun, compared to January, the weather in India and nearby areas is mostly very hot.
This clearly shows that the distance from the earth to the sun does not determine the seasons, but the inclination of its journey around the sun each year.
Mr. Kumar said that, just like every year, in 2021, the celestial event from the Earth’s perihelion (nearest point) to the Sun will occur on January 2, 2021. The celestial event from the aphelion (furthest point) from the earth to the sun occurred on July 6, 2021. So in this year, 2021, compared with July 6, the earth will be close to 50,07,355 kilometers from the sun on January 2, 2021.
He said that it takes 365.25 days for the earth to revolve around the sun. This is a fact. In contrast, Mercury needs about 87.96 Earth days, while Venus needs 224.7 Earth days to complete a revolution around the sun.
This means that people on Mercury celebrate the New Year every 88 days, while people on Venus celebrate every 225 days.
Just like the Earth or even Mercury, Venus is also closer (perihelion) and farther (aphelion) at some point in its revolution. Therefore, on January 16, 2022, Mercury will be located at perihelion (nearest point) to the sun. On January 23, 2022, Venus will be located at the perihelion (nearest point) to the sun.
On that day, although people will not be able to notice or observe any major events related to these three astronomical events in January. It has greater educational value and scientific awareness.
It is important that people understand that the temperature or seasons on the earth do not depend on the distance from the earth to the sun, but the axial tilt during travel around the sun.

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine

Taking regular breaks from intense training, like deload weeks, helps your body recover, preventing fatigue and injury, and ultimately boosts fitness gains.

When it comes to getting fit, the idea of spending hours at the gym might come to mind, but many fitness experts argue that taking a “deload week” every six to eight weeks is actually key to improving your fitness gains. A deload week involves reducing the intensity of workouts to allow the body to recover from the fatigue and muscle damage caused by intense training.

While high-intensity training helps build strength and fitness, it can also lead to muscle strain, and without adequate recovery, these gains can’t fully materialise. Deload weeks give the body much-needed rest to repair and rebuild, ensuring continued progress. (Also read: Bhagyashree swears by this super easy exercise for instant leg pain relief and better mobility.

Why recovery is key for muscle growth

According to an article by The Conversation, intense exercise can cause tiny tears in muscle fibres, leading to inflammation that requires rest or low-intensity exercise to heal. This inflammation is essential for muscle growth and fitness improvements. However, without proper recovery, muscles remain in a state of slight damage, preventing inflammation from resolving. This chronic state of inflammation can hinder muscle function, reducing oxygen efficiency and impairing performance. Giving muscles time to recover through rest ensures they repair properly and are primed for continued progress, setting us up for greater success in our fitness journey.

Many gymgoers fear taking time off and are worried it will lead to a loss of gains. However, research shows that muscle genes have a “memory imprint,” which keeps them in a semi-prepared state. This allows muscles to respond more quickly and effectively to future training, promoting growth after a rest period. Even after extended periods of reduced intensity, up to seven weeks, muscular fitness can be restored to prime condition—and in some cases, surpass previous levels. Interestingly, recovery can occur twice as fast as it took to reach peak fitness initially, even if some strength is lost.

Taking time off from intense training is crucial to prevent muscle soreness and avoid overtraining syndrome. Overtraining occurs when the body doesn’t get enough rest, leading to prolonged fatigue, decreased performance, and mood disturbances. Symptoms develop gradually, making overtraining difficult to recognize until it’s severe. Rest is essential to avoid these issues and ensure long-term progress in training.

Role of overtraining syndrome and deload weeks

Overtraining syndrome is challenging to quantify due to its vague symptoms. Studies suggest it may affect as few as 10% of elite athletes, though rates could climb to 60% among highly competitive individuals. Recovery is essential for both fitness and overall health. When engaging in heavy gym routines, it’s vital to incorporate sufficient recovery time into your workout plan. Unlike rest days, which involve little to no exercise once or twice a week, deload weeks feature lighter training at reduced intensity—typically about 50% fewer workouts or a 20% drop in workout intensity.

Both rest days and deload weeks are essential for recovery and crucial to improving fitness. It’s not about choosing one over the other—they complement each other. For instance, intense training for marathons, Ironman, or CrossFit competitions requires weekly rest days alongside scheduled deload weeks. However, for recreational gym-goers exercising 1–3 times weekly at a moderate intensity, the recovery from this routine is often sufficient without the need for additional deload weeks.

Fitness influencers recommend incorporating deload weeks into training schedules every 4–8 weeks, aligning closely with the expert advice of 4–6 weeks. However, it’s crucial to listen to your body and schedule deload weeks as needed. If your performance plateaus or worsens, it may signal time for a deload. Training plans should be flexible enough to allow rest when required. Deload weeks not only enhance performance but also support overall health.
