Science v/s myth: What actually keeps you warm
What's the story
A lot of us hold onto those beliefs about what keeps us warm on a cold day.
One common belief is drinking hot beverages, thinking it warms you up from the inside.
But, it's important to bust these myths with science to know what really affects our body's temperature regulation.
Myth 1
The myth of warming beverages
The notion that certain beverages can "warm the body" is a myth deeply rooted in many cultures. The truth, however, is backed by science.
Drinking them doesn't raise your core body temperature; it causes peripheral vasodilation.
This expands blood vessels near your skin, creating a temporary warmth but actually drawing heat away from your core.
It's a misleading sensation that can ultimately decrease your body temperature in cold environments.
Myth 2
Understanding true warmth sources
Another pervasive myth is that specific foods or drinks can function as internal heaters during winter months.
While the metabolism of food does produce heat (a process called thermogenesis), no food or drink significantly raises the body's core temperature.
The secret to warmth isn't found in immediate fixes but rather in balanced nutrition and supporting healthy circulation.
Myth 3
Layering up vs consuming for warmth
Many believe hot drinks or spicy foods are more effective at warming you up than dressing appropriately for the cold.
This underestimates the importance of clothing and shelter in conserving heat.
Layering is the key. It traps heat and keeps out the cold air more effectively than any food or drink. This is the most crucial strategy for staying warm.
Myth 4
The role of hydration in temperature regulation
A myth implies that dehydration helps retain warmth by limiting the amount of body fluid available to cool down, but this is a misconception.
Hydration is essential for maintaining normal body temperature and circulation.
Dehydration impairs heat production and actually increases cooling in cold environments, emphasizing the need for adequate hydration in all weather conditions.
