A study from June 2025 suggested there’s one issue that’s clearly linked to a whopping 172 diseases. Perhaps even scarier, it’s a common one: disrupted sleep patterns. Researchers looked at more than 88,000 people’s data from the UK Biobank, a large-scale biomedical database in Britain, and found that poor sleep was associated with a higher risk of many conditions. Before we go any further, it’s important to note that, as with many studies, these findings are possibilities — not confirmed facts.
