Let's focus on love everyday!❤️
Happy Valentine’s Day ♥️ let this be your reminder that love is not limited to romance.
Whether you are married, single, dating, widowed, or somewhere in between, what matters biologically is meaningful connection.
Time with close friends.
A deep conversation.
A hug from someone you trust.
Feeling part of a community.
Research in the field of social genomics shows that chronic stress and loneliness are linked to increased activity of genes that promote inflammation within the immune system.
In contrast, people who feel supported, connected, and emotionally safe tend to show lower activation of these same inflammatory pathways. Scientists describe this pattern as the Conserved Transcriptional Response to Adversity, a gene expression profile shaped in part by how safe or threatened we feel in our social world.
Feeling seen and supported is associated with measurable shifts in immune regulation, including reduced activation of inflammatory gene pathways linked to long-term chronic disease risk.
Connection is a fundamental human nutrient. And your body responds to it at the level of your genes.
