The Notion ‘Cold Temperature Increases Lifespan’ Challenged




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.

What Interferes with Successful Breastfeeding?




While breastfeeding is ideal, it comes with many difficulties new parents might face.

After experiencing the intensity of labor and delivery, many new parents are left exhausted. Despite this fatigue and surviving pospartum, new parents soon learn the importance of managing the needs of an infant. Putting aside their own desires, parents learn to quickly adapt.

Exhaustion and recovery are not the only things that discourage parents from breastfeeding. There are a variety of other woes that can make it difficult for a lactating parent to continue to choose this option. 

While 83 percent of women breastfeed at the beginning of postpartum, there is a drastic reduction by 6 months, resulting in only 56% of babies still being breastfed. 

Engorged Breasts

When a lactating woman’s milk comes in, she may experience intense pain and discomfort. The breasts typically become overly filled with milk because they have not yet regulated their supply. This engorgement can continue throughout the breastfeeding journey for a variety of reasons.

If the baby’s schedule changes, a woman’s breasts can become overly full. If the parent misses a feeding, breasts can experience discomfor which can lead to breastfeeding infection. If a woman becomes preoccupied at work and does not make time to pump, she can experience discomfort. 

If breast engorgement is not treated properly, milk ducts can become blocked, and if a woman does not work to move the milk through her breasts (via feeding her baby, pumping, or expressing the milk), this engorgement can lead to further problems and may cause clogged milk ducts.


One of the biggest concerns beyond the pain a woman experiences with engorgement is infection. This is known as mastitis, and leads to a woman experiencing not only breast pain and warm breast tissue, but also flu-like symptoms that come with fever, chills, headache, and further exhaustion.

In order to help prevent infection, regular feedings are essential. Often, the best mastitis treatment, at least for early symptoms, is to massage the breast in a warm shower and express the extra milk.

Furthermore, by working with an International Board Certified Lactation Consultant (IBCLC), parents can have a great resource on how to best deal with, treat, and alleviate these problems. 

Not only is an IBCLC a great resource in helping prevent breast infection, but a great source for your breastfeeding journey to encourage and educate you in best practices. 

The best way to achieve breastfeeding success is to utilize the many tools that an IBCLC offers. 


To exclusively breastfeed your baby can be quite overwhelming and exhausting. Between nightly feedings, cluster feedings, and pumping sessions for working mothers, breastfeeding is difficult to maintain. Unless a woman is properly supported by her family, friends, and workplace, the chances that a woman will continue to breastfeed are significantly impacted.

Culture also impacts the likelihood of a baby being breastfed beyond 6 months. The CDC discovered that parents in the Southeast United States are less likely to breastfeed their children past six months. This was in contrast to the Northwest, where business policies and the culture is more breastfeeding-friendly and supportive. 


Despite the nutritional benefits afforded to a breastfed baby, there are many obstacles that can be discouraging for parents on their breastfeeding journey. From exhaustion to pain to lack of supoort, parents have many reasons to give up. 

To increase your chances of success, surround yourself with supportive individuals, reach out to an IBCLC, also known as lactation consultants, and gain the necessary tools required to provide your child with the healthiest option available – you!
