cold temperature increases lifespan - challenged

There is a poplar belief according to the free radical theory, that cold temperatures increase the lifespan of a person, because the metabolic rate slows down due to cold. But this notion has been challenged by a recent research about aging process.

Some scientists working at Marine Biological Laboratory in Woods Hole, MA, revealed that the genes of a person play a major role in determining how much the cold temperature affects his or her lifespan. This university is an affiliate of University of Chicago, in Illinois.

For this research, tiny aquatic animals called rotifers were chosen. They make the perfect choice because they have more genes in common with humans. Moreover, they are transparent in shape, which makes it easy to study them properly. Not just that, they also possess a nervous system along with the brain, muscles, reproduction system, and digestive system. All of these traits make them highly similar to the humans.

If going by the free radical theory, all creatures should age slowly due to the cold temperatures. When this research was carried out on 11 strains of rotifers, results were highly varied. According to the popular belief, each rotifer should reach similar in cold temperatures. However that was not the case.

According to the results, each strain of rotifers gave different response to the test. There was a change in median lifespan of each strain, ranging from -6% to +100%. In some strains, the cold temperature also extended their reproductive period, which means increase in healthspan.

So, based on the latest research, the genetic makeup affects the response of body to cold temperatures. It can even increase the health span of a person, although it may not alter the lifespan. In short, when it comes to aging, genetic makeup should also be taken into consideration when going for any research.

Best Times to Take Whey Protein Isolate for Optimal Results

For anyone looking to build muscle, recover faster, or simply improve their overall nutrition, timing can make a big difference when it comes to protein intake. Whey protein isolate is one of the most efficient and bioavailable sources of protein available — easily absorbed by the body and ideal for supporting recovery and growth. Whether you’re a seasoned athlete or just starting your fitness journey, knowing the best times to take it can help you make the most of its benefits. If you’re looking for a high-quality option, explore premium whey protein isolate in Australia to fuel your results.

1. Post-Workout: The Prime Time for Recovery

The period immediately after your workout is arguably the best time to consume whey protein isolate. During exercise, your muscles experience micro-tears and deplete their glycogen stores. Consuming whey protein isolate within 30 minutes post-training provides your body with fast-digesting amino acids, which help repair muscle tissue and stimulate protein synthesis.

Pairing your shake with a source of carbohydrates can further enhance recovery by replenishing glycogen stores and promoting better nutrient absorption.

2. First Thing in the Morning

After several hours of sleep, your body wakes up in a fasted state. Consuming whey protein isolate in the morning helps prevent muscle breakdown and kickstarts your metabolism for the day. It’s particularly useful if you don’t have time for a full breakfast or if you train early in the morning.

This quick, easily digestible protein gives your muscles a readily available source of amino acids to maintain muscle mass and energy levels throughout the morning.

3. Between Meals to Support Protein Intake

If you struggle to meet your daily protein goals through food alone, taking whey protein isolate between meals is a simple way to boost your intake. This is especially beneficial for those aiming to build lean muscle or lose fat while maintaining muscle mass.

A mid-morning or mid-afternoon shake helps stabilise blood sugar levels and reduces the temptation to reach for less nutritious snacks.

4. Before Bed (When Needed)

While casein protein is traditionally recommended for nighttime use due to its slow digestion, whey protein isolate can also be beneficial before bed in certain cases — particularly for those who train late in the evening or need additional daily protein intake.

Although it digests quickly, it still provides your muscles with amino acids to support repair and recovery during the early stages of sleep.

Optimising Your Protein Strategy

Ultimately, the best time to take whey protein isolate depends on your fitness goals, training schedule, and dietary habits. The most important thing is to ensure you’re consistently meeting your total daily protein needs. Whey protein isolate’s versatility makes it easy to integrate into your lifestyle — from breakfast smoothies to post-workout shakes.
