There are several reasons why the elderly do not sleep well: 1, physiological reasons: with age, brain cells shrink, thus affecting sleep. 2, psychosocial factors: the elderly are more susceptible to social and psychological interference, affected by events such as widowhood or retirement, which leads to poor sleep. 3, environmental factors: the home is more noisy, etc. 4, the use of excitatory drugs: drugs used to treat asthma can also make patients more prone to excitement, which can affect sleep. If the insomnia is not particularly serious, you can take oral sleep-aiding drugs to improve.
