Spending time in nature: How natural environments can foster a healthier relationship with time

Recent research highlights nature’s potential benefits in alleviating the pressures of contemporary urban living by influencing human perceptions of time. This understanding could pave the way for creating healthier living environments that integrate the therapeutic qualities of natural settings.

In modern lifestyles, time is a pivotal element, often equated with money and considered a resource that must be carefully managed. This perspective is especially prevalent among urban dwellers, who are typically required to sync their daily activities with the precise ticking of the clock rather than the more fluid rhythms of the natural world. Such an intense focus on mechanical time has been shown to negatively impact cognitive functions and overall well-being, with an increasing number of people experiencing a pervasive sense of time scarcity. This raises an intriguing question: could a reconnection with the natural world and its inherent rhythms lead to a more balanced and healthier time perception?

Dr. Ricardo Correia, Assistant Professor at the University of Turku, Finland, discusses how time perception is a highly subjective phenomenon influenced by various factors, including attention, memory, emotions, and physical condition. He notes that while time may seem to drag during mundane or stressful situations, such as being stuck in traffic, it tends to pass quickly during enjoyable interactions. According to Dr. Correia, urban living exerts considerable pressure on the mechanisms that govern time perception. In contrast, nature has a vital impact, helping individuals recalibrate and achieve a more balanced temporal perspective.

Dr. Correia’s review of scientific literature concerning the interplay between human time perception and natural environments reveals that experiences in nature have a positive impact on at least two aspects of time perception: temporal duration and temporal perspective. Temporal duration refers to how people perceive and experience the length and passage of time. Studies indicate that durations spent in natural settings are overestimated, suggesting that time stretches longer than in urban contexts. This phenomenon could offer a sense of having more time, which is valuable in combating the feelings of constant rush and insufficient time typical of urban living.

Moreover, evidence suggests that being in natural environments can alter people’s temporal perspective, which involves the ability to traverse past, present, and future mentally. While some individuals may dwell on the past due to nostalgia or trauma, others might focus predominantly on the present or future, driven by immediate pleasures or long-term goals. A heavy bias towards any single temporal frame can be detrimental, often linked to risky behaviours and poor mental health. Nature encourages a more fluid and balanced movement between these temporal states, fostering a healthier and more holistic view of time.

Dr. Correia strongly believes in the significant role of nature in nurturing a healthier temporal perception and asserts that the influence of natural environments on human well-being deserves greater recognition. He also points out the need for more detailed research on specific natural elements or experiences most effectively influencing time perception. Such insights could be crucial in designing urban spaces, like parks and recreational areas, to enhance collective well-being by integrating natural elements that help regulate our perception of time.

In conclusion, the research on the relationship between nature and time perception offers a promising avenue for enhancing individual and community health. It also underscores the need for a strategic urban planning and development approach. By integrating natural elements in urban environments, we can create spaces that not only enhance life quality but also promote a more balanced relationship with time, thereby benefiting the well-being of urban dwellers.

Revolutionising Shrimp Waste: Harnessing Powerful Antioxidants for Health and Sustainability

Scientists have unveiled groundbreaking antioxidative compounds in Northern shrimp (Pandalus borealis), marking a significant advancement for the food and pharmaceutical industries. This discovery highlights not only the nutritional richness of shrimp but also introduces new compounds with promising health benefits.

Shrimp, known for their substantial nutritional content, also contain valuable substances like chitin and carotenoids. However, with the global rise in shrimp consumption, by-products such as heads, shells, and tails, which can constitute up to 50% of waste, pose a significant environmental challenge. Shrimp shells, in particular, are rich in minerals, proteins, and chitin. This research, therefore, holds the key to transforming these by-products into value-added products, offering a sustainable solution to the environmental issue.

A recent study published in the journal Food Production, Processing and Nutrition on 28 February 2024, conducted by researchers from Memorial University of Newfoundland, has identified antioxidative compounds in Northern shrimp, signalling a vital breakthrough for both the food and pharmaceutical sectors. The study not only reaffirms the nutritional importance of shrimp but also uncovers novel compounds that provide potential health advantages.

In this research, ethanol emerged as the most effective solvent for extracting antioxidant elements from shrimp by-products, especially the shells, which exhibited high levels of total phenolic content (TPC) and carotenoid content (TCC). This finding not only highlights the efficiency of ethanol in extraction processes but also exposes the strong antioxidative properties present in shrimp waste. Utilising advanced chromatographic techniques and mass spectrometry, the researchers isolated phenolic compounds, marking a significant step in exploring the nutritional potential of shrimp. The precise analysis and isolation process, involving silica gel column chromatography and thin-layer chromatography (TLC), resulted in the discovery of groundbreaking compounds such as 7-(3-butenyl)-2-hydroxy-6-(1,2,5,6-tetrahydropyridin-2-yl) quinoline and its dihydroquinoline variant, which unveil complex antioxidative mechanisms in shrimp and open up new possibilities for further scientific research and potential health-related applications. The study points to the rich yet underutilised antioxidant sources in shrimp by-products, encouraging a more extensive examination of seafood waste and proposing new avenues for nutritional and pharmaceutical developments.

Dr Fereidoon Shahidi, a co-author of the study, stressed the importance of these discoveries. He noted that the identification of these unique heterocyclic phenolic compounds not only sheds light on shrimp’s antioxidative properties but also fosters new opportunities for using shrimp by-products in ways that align with sustainable and waste-minimising practices in the seafood industry. He further suggested that structural conformation could benefit from advanced techniques like 3D NMR, which have become more accessible since the original research was conducted.

This breakthrough not only highlights the untapped potential of shrimp processing waste but also introduces novel compounds with significant health implications. These compounds could potentially offer anti-inflammatory, anticancer, and anti-ageing benefits, opening up a new frontier in health-related applications. Furthermore, it promotes a sustainable approach to seafood processing, converting waste into valuable health-promoting agents.
