Loneliness in numbers.
Loneliness is a part of life and something that most of us experience at some point. But when loneliness is severe or lasts a long time, it can have a negative impact on our health and well-being.
Recent studies suggest that long-term loneliness is one of the largest health concerns we face. It is as harmful as obesity or smoking 15 cigarettes a day. Feeling lonely can lead to depression, anxiety, disrupted sleep and stress. It can also be a factor in heart disease, increased blood pressure and degenerative brain diseases such as Alzheimer’s.
